Myopia
A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.
Myopia, Degenerative
Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.
Refraction, Ocular
Refraction of LIGHT effected by the media of the EYE.
Eyeglasses
A pair of ophthalmic lenses in a frame or mounting which is supported by the nose and ears. The purpose is to aid or improve vision. It does not include goggles or nonprescription sun glasses for which EYE PROTECTIVE DEVICES is available.
Hyperopia
A refractive error in which rays of light entering the eye parallel to the optic axis are brought to a focus behind the retina, as a result of the eyeball being too short from front to back. It is also called farsightedness because the near point is more distant than it is in emmetropia with an equal amplitude of accommodation. (Dorland, 27th ed)
Refractive Errors
Deviations from the average or standard indices of refraction of the eye through its dioptric or refractive apparatus.
Sensory Deprivation
The absence or restriction of the usual external sensory stimuli to which the individual responds.
Eye
The organ of sight constituting a pair of globular organs made up of a three-layered roughly spherical structure specialized for receiving and responding to light.
Accommodation, Ocular
The dioptric adjustment of the EYE (to attain maximal sharpness of retinal imagery for an object of regard) referring to the ability, to the mechanism, or to the process. Ocular accommodation is the effecting of refractive changes by changes in the shape of the CRYSTALLINE LENS. Loosely, it refers to ocular adjustments for VISION, OCULAR at various distances. (Cline et al., Dictionary of Visual Science, 4th ed)
Sclera
The white, opaque, fibrous, outer tunic of the eyeball, covering it entirely excepting the segment covered anteriorly by the cornea. It is essentially avascular but contains apertures for vessels, lymphatics, and nerves. It receives the tendons of insertion of the extraocular muscles and at the corneoscleral junction contains the canal of Schlemm. (From Cline et al., Dictionary of Visual Science, 4th ed)
Axial Length, Eye
The distance between the anterior and posterior poles of the eye, measured either by ULTRASONOGRAPHY or by partial coherence interferometry.
Tupaiidae
The only family of the order SCANDENTIA, variously included in the order Insectivora or in the order Primates, and often in the order Microscelidea, consisting of five genera. They are TUPAIA, Ananthana (Indian tree shrew), Dendrogale (small smooth-tailed tree shrew), Urogale (Mindanao tree shrew), and Ptilocercus (pen-tailed tree shrew). The tree shrews inhabit the forest areas of eastern Asia from India and southwestern China to Borneo and the Philippines.
Retinoscopy
An objective determination of the refractive state of the eye (NEARSIGHTEDNESS; FARSIGHTEDNESS; ASTIGMATISM). By using a RETINOSCOPE, the amount of correction and the power of lens needed can be determined.
Emmetropia
The condition of where images are correctly brought to a focus on the retina.
Biometry
The use of statistical and mathematical methods to analyze biological observations and phenomena.
Tupaia
A genus of tree shrews of the family TUPAIIDAE which consists of about 12 species. One of the most frequently encountered species is T. glis. Members of this genus inhabit rain forests and secondary growth areas in southeast Asia.
Astigmatism
Unequal curvature of the refractive surfaces of the eye. Thus a point source of light cannot be brought to a point focus on the retina but is spread over a more or less diffuse area. This results from the radius of curvature in one plane being longer or shorter than the radius at right angles to it. (Dorland, 27th ed)
Lasers, Excimer
Gas lasers with excited dimers (i.e., excimers) as the active medium. The most commonly used are rare gas monohalides (e.g., argon fluoride, xenon chloride). Their principal emission wavelengths are in the ultraviolet range and depend on the monohalide used (e.g., 193 nm for ArF, 308 nm for Xe Cl). These lasers are operated in pulsed and Q-switched modes and used in photoablative decomposition involving actual removal of tissue. (UMDNS, 2005)
Photorefractive Keratectomy
A type of refractive surgery of the CORNEA to correct MYOPIA and ASTIGMATISM. An EXCIMER LASER is used directly on the surface of the EYE to remove some of the CORNEAL EPITHELIUM thus reshaping the anterior curvature of the cornea.
Visual Acuity
Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.
Keratomileusis, Laser In Situ
A surgical procedure to correct MYOPIA by CORNEAL STROMA subtraction. It involves the use of a microkeratome to make a lamellar dissection of the CORNEA creating a flap with intact CORNEAL EPITHELIUM. After the flap is lifted, the underlying midstroma is reshaped with an EXCIMER LASER and the flap is returned to its original position.
Contact Lenses
Lenses designed to be worn on the front surface of the eyeball. (UMDNS, 1999)
Lenses
Pieces of glass or other transparent materials used for magnification or increased visual acuity.
Keratotomy, Radial
A procedure to surgically correct REFRACTIVE ERRORS by cutting radial slits into the CORNEA to change its refractive properties.
Corneal Topography
The measurement of curvature and shape of the anterior surface of the cornea using techniques such as keratometry, keratoscopy, photokeratoscopy, profile photography, computer-assisted image processing and videokeratography. This measurement is often applied in the fitting of contact lenses and in diagnosing corneal diseases or corneal changes including keratoconus, which occur after keratotomy and keratoplasty.
Cornea
The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed)
Orthokeratologic Procedures
An alternative to REFRACTIVE SURGICAL PROCEDURES. A therapeutic procedure for correcting REFRACTIVE ERRORS. It involves wearing CONTACT LENSES designed to force corrective changes to the curvature of the CORNEA that remain after the lenses are removed. The effect is temporary but is maintained by wearing the therapeutic lenses daily, usually during sleep.
Vitreous Body
The transparent, semigelatinous substance that fills the cavity behind the CRYSTALLINE LENS of the EYE and in front of the RETINA. It is contained in a thin hyaloid membrane and forms about four fifths of the optic globe.
Singapore
Anterior Chamber
The space in the eye, filled with aqueous humor, bounded anteriorly by the cornea and a small portion of the sclera and posteriorly by a small portion of the ciliary body, the iris, and that part of the crystalline lens which presents through the pupil. (Cline et al., Dictionary of Visual Science, 4th ed, p109)
Asian Continental Ancestry Group
Individuals whose ancestral origins are in the southeastern and eastern areas of the Asian continent.
Keratectomy, Subepithelial, Laser-Assisted
A surgical technique to correct REFRACTIVE ERRORS of the EYE, such as MYOPIA and ASTIGMATISM. In this method, a flap of CORNEAL EPITHELIUM is created by exposure of the area to dilute alcohol. The flap is lifted and then replaced after laser ablation of the subepithelial CORNEA.
Refractive Surgical Procedures
Surgical procedures employed to correct REFRACTIVE ERRORS such as MYOPIA; HYPEROPIA; or ASTIGMATISM. These may involve altering the curvature of the CORNEA; removal or replacement of the CRYSTALLINE LENS; or modification of the SCLERA to change the axial length of the eye.
Mydriatics
Agents that dilate the pupil. They may be either sympathomimetics or parasympatholytics.
Anisometropia
A condition of an inequality of refractive power of the two eyes.

Streptococcal keratitis after myopic laser in situ keratomileusis. (1/1261)

A 24-year-old healthy male underwent uncomplicated laser in situ keratomileusis (LASIK) in left eye. One day after the surgery, he complained of ocular pain and multiple corneal stromal infiltrates had developed in left eye. Immediately, the corneal interface and stromal bed were cleared, and maximal antibiotic treatments with fortified tobramycin (1.2%) and cefazolin (5%) were given topically. The causative organism was identified as 'Streptococcus viridans' both on smear and culture. Two days after antibiotic therapy was initiated, the ocular inflammation and corneal infiltrates had regressed and ocular pain was relieved. One month later, the patient's best corrected visual acuity had returned to 20/20 with -0.75 -1.00 x 10 degrees, however minimal stromal scarring still remained. This case demonstrates that microbial keratitis after LASIK, if treated promptly, does not lead to a permanent reduction in visual acuity.  (+info)

Tonic accommodation, age, and refractive error in children. (2/1261)

PURPOSE: An association between tonic accommodation, the resting accommodative position of the eye in the absence of a visually compelling stimulus, and refractive error has been reported in adults and children. In general, myopes have the lowest (or least myopic) levels of tonic accommodation. The purpose in assessing tonic accommodation was to evaluate it as a predictor of onset of myopia. METHODS: Tonic accommodation was measured in children enrolled in the Orinda Longitudinal Study of Myopia using an infrared autorefractor (model R-1; Canon, Lake Success, NY) while children viewed an empty lit field or a dark field with a fixation spot projected in Maxwellian view. Children aged 6 to 15 years were measured from 1991 through 1994 (n = 714, 766, 771, and 790 during the 4 years, successively). Autorefraction provided refractive error and tonic accommodation data, and videophakometry measured crystalline lens curvatures. RESULTS: Comparison of the two methods for measuring tonic accommodation shows a significant effect of age across all years of testing, with the lit empty-field test condition yielding higher levels of tonic accommodation compared with the dark-field test condition in children aged 6 through 11 years. For data collected in 1994, mean (+/-SD) tonic accommodation values for the lit empty-field condition were significantly lower in myopes, intermediate in emmetropes, and highest in hyperopes (1.02 +/- 1.18 D, 1.92 +/- 1.59 D, and 2.25 +/- 1.78 D, respectively; Kruskal-Wallis test, P < 0.001; between-group testing shows each group is different from the other two). Age, refractive error, and Gullstrand lens power were significant terms in a multiple regression model of tonic accommodation (R2 = 0.18 for 1994 data). Lower levels of tonic accommodation for children entering the study in the first or third grades were not associated with an increased risk of the onset of myopia, whether measured in the lit empty-field test condition (relative risk = 0.90; 95% confidence interval = 0.75, 1.08), or the dark-field test condition (relative risk = 0.83; 95% confidence interval = 0.60, 1.14). CONCLUSIONS: This is the first study to document an association between age and tonic accommodation. The known association between tonic accommodation and refractive error was confirmed and it was shown that an ocular component, Gullstrand lens power, also contributed to the tonic accommodation level. There does not seem to be an increased risk of onset of juvenile myopia associated with tonic accommodation.  (+info)

Colchicine causes excessive ocular growth and myopia in chicks. (3/1261)

Colchicine has been reported to destroy ganglion cells (GCs) in the retina of hatchling chicks. We tested whether colchicine influences normal ocular growth and form-deprivation myopia, and whether it affects cells other than GCs. Colchicine greatly increased axial length, equatorial diameter, eye weight, and myopic refractive error, while reducing corneal curvature. Colchicine caused DNA fragmentation in many GCs and some amacrine cells and photoreceptors, ultimately leading to the destruction of most GCs and particular sub-sets of amacrine cells. Colchicine-induced ocular growth may result from the destruction of amacrine cells that normally suppress ocular growth, and corneal flattening may result from the destruction of GCs whose central pathway normally plays a role in shaping the cornea.  (+info)

The growing eye: an autofocus system that works on very poor images. (4/1261)

It is unknown which retinal image features are analyzed to control axial eye growth and refractive development. On the other hand, identification of these features is fundamental for the understanding of visually acquired refractive errors. Cyclopleged chicks were individually kept in the center of a drum with only one viewing distance possible. Defocusing spectacle lenses were used to stimulate the retina with defined defocus of similar magnitude but different sign. If spatial frequency content and contrast were the only cues analyzed by the retina, all chicks should have become myopic. However, compensatory eye growth was still always in the right direction. The most likely cues for emmetropization, spatial frequency content and image contrast, do therefore not correlate with the elongation of the eye. Rather, the sign of defocus was extracted even from very poor images.  (+info)

Naturally occurring vitreous chamber-based myopia in the Labrador retriever. (5/1261)

PURPOSE: To investigate whether myopia is present in a breed of domestic dog, the Labrador retriever, and how the ocular components are related to refractive error in this breed. METHODS: Cycloplegic refractive error was measured in 75 Labrador retrievers by retinoscopy. Corneal and crystalline lens radii of curvature were measured in the right eyes of 57 of these dogs using a video-based keratophakometer, with axial ocular dimensions measured using A-scan ultrasonography. RESULTS: Of the 75 dogs tested, 11 (14.7%) were myopic by at least -0.50 D in one eye, and 6 (8.0%) were myopic in both eyes (full range of refractive errors, +3.50 D to -5.00 D). Of the 57 dogs with ocular component measurements, seven (12.3%) were myopic by at least -0.50 D in the right eye. There was a significant negative correlation between refractive error and vitreous chamber depth (Spearman r = -0.42; P < 0.001). Myopic eyes had an elongated vitreous chamber depth (10.87+/-0.34 mm for myopic dogs, 10.02+/-0.40 mm for nonmyopic dogs; P < 0.0001, Kruskal-Wallis test). There was also a significant quadratic association between lens thickness and vitreous chamber depth (P < 0.005; R2 = 0. 11), indicating that thinner lenses occurred at both shorter and longer vitreous chamber depths. CONCLUSIONS: Myopia in the Labrador retriever is analogous to human myopia in that it is caused by an elongated vitreous chamber. Thinner crystalline lenses found at longer vitreous chamber depths may be analogous to lens thinning documented in human ocular development. The Labrador retriever warrants investigation as a potential model of myopia that is naturally occurring rather than experimentally induced.  (+info)

Spherical and aspherical photorefractive keratectomy and laser in-situ keratomileusis for moderate to high myopia: two prospective, randomized clinical trials. Summit technology PRK-LASIK study group. (6/1261)

OBJECTIVE: Determine the outcomes of single-zone photorefractive keratectomy (SZPRK), aspherical photorefractive keratectomy (ASPRK), and laser in-situ keratomileusis (LASIK) for the correction of myopia between -6 and -12 diopters. DESIGN: Two simultaneous prospective, randomized, multi-center clinical trials. PARTICIPANTS: 286 first-treated eyes of 286 patients enrolled in one of two studies. In Study I, 134 eyes were randomized to SZPRK (58 eyes) or ASPRK (76 eyes). In Study II, 152 eyes were randomized to ASPRK (76 eyes) or to LASIK (76 eyes). INTERVENTION: All eyes received spherical one-pass excimer laser ablation as part of PRK or LASIK performed with the Summit Technologies Apex laser under an investigational device exemption, with attempted corrections between -6 and -12 diopters. MAIN OUTCOME MEASURES: Data on uncorrected and best spectacle-corrected visual acuity, predictability and stability of refraction, and complications were analyzed. Follow-up was 12 months. RESULTS: At 1 month postoperatively, more eyes in the LASIK group achieved 20/20 and 20/25 or better uncorrected visual acuity than PRK-treated eyes; at the 20/25 or better level, the difference was significant for LASIK (29/76 eyes, 38%) over SZPRK (10/58 eyes, 17%) (P = .0064). At all subsequent postoperative intervals, no difference was seen between treatment groups. Similarly, best corrected visual acuities were better for LASIK than all PRK eyes at 1 month postoperatively, and LASIK was better than SZPRK at 3 months follow-up (e.g., for 20/20 or better at 1 month, LASIK 50/76 eyes (66%) versus SZPRK 24/57 eyes (42%), P = .0066). PRK eyes had a mean loss of BCVA through 6 months, while LASIK eyes had a slight gain of mean BCVA through month 6; at 12 months, both ASPRK groups but not SZPRK continued to have a small mean loss of BCVA (e.g., compared to preoperative, mean BCVA at 12 months for SZPRK was + 0.3, LASIK was +.21, ASPRK I was -0.11, and ASPRK II -0.31 (SZPRK versus ASPRK II, P = .0116). Predictability was better for PRK than LASIK at all follow-up intervals (e.g., for manifest refraction spherical equivalent +/- 1.0 diopters at 6 months, ASPRK I 42/62 eyes (68%) versus LASIK 29/72 eyes (40%), P = .0014%). Stability was slightly but insignificantly less in the LASIK eyes compared to PRK eyes. All visual outcome measures were better for eyes with preoperative myopia between -6 and -8.9 D compared with eyes with myopia between -9 and -12 D. No consistent differences in refractive outcomes or postoperative corneal haze were seen between aspherical and single-zone ablations; haze diminished over 12 months and was judged to be vision-impairing in only one ASPRK eye. Microkeratome and flap complications occurred in 4 eyes, resulting in delay of completion of the procedure in 3 eyes but not causing long-term impairment. CONCLUSIONS: Improvement in uncorrected visual acuity and return of best corrected visual acuity was more rapid for LASIK than PRK, but efficacy outcomes in the longer term through 12 months were similar for all treatment groups. LASIK eyes tended toward undercorrection with the nomogram employed in this study compared to PRK, but the scatter was similar, suggesting little difference between these procedures for most patients by 6 months and thereafter. No consistent advantage was demonstrated between aspherical and single-zone ablation patterns. Predictability was much better for all procedures for corrections of -6 to -8.9 D compared with -9 to -12 D. Sporadic loss of best corrected vision in the PRK eyes not found in the LASIK eyes and other measures of visual function require further study.  (+info)

Enhancement ablation for the treatment of undercorrection after excimer laser in situ keratomileusis for correcting myopia. (7/1261)

OBJECTIVE: To evaluate the treatment of undercorrection after the excimer laser in situ keratomileusis (LASIK) for correcting moderate and high myopia. METHODS: An enhancement ablation was performed in 48 eyes of 39 patients who had undergone LASIK but remained in undercorrection. Four procedures were performed within 1 month postoperatively, and the others performed between 3 and 10 months. The surgical technique includes the re-invert of the corneal cap from the temporal side, the excimer laser ablation, and the re-position of the cap. RESULTS: The undercorrection (spherical equivalent) ranged from -2.00 to -11.00 D, with a mean of -4.34D +/- 1.95 D. Following up after enhancement ablation was done after 4 to 12 months, the refractions in the 42 eyes were found to be within +/- 1.00 D. Undercorrection of -2.50 D to -5.00 D recurred in 6 eyes. Uncorrected visual acuity equals to the preoperative spectacle corrected visual acuity in 39 of 48 eyes (81.3%). Five eyes gained 1 line, 1 eye gained 2 lines and 4 eyes lost 1 line. No eyes had haze. CONCLUSION: Undercorrection after LASIK can be corrected by an enhancement ablation of the stroma under the primary corneal cap with a 193 nm ArF excimer laser, and the time for the enhancement of ablation is at 3 months postoperatively.  (+info)

Long-term changes in retinal contrast sensitivity in chicks from frosted occluders and drugs: relations to myopia? (8/1261)

Experiments in animal models have shown that the retinal analyzes the image to identify the position of the plane of focus and fine-tunes the growth of the underlying sclera. It is fundamental to the understanding of the development of refractive errors to know which image features are processed. Since the position of the image plane fluctuates continuously with accommodative status and viewing distance, a meaningful control of refractive development can only occur by an averaging procedure with a long time constant. As a candidate for a retinal signal for enhanced eye growth and myopia we propose the level of contrast adaptation which varies with the average amount of defocus. Using a behavioural paradigm, we have found in chickens (1) that contrast adaptation (CA, here referred to as an increase in contrast sensitivity) occurs at low spatial frequencies (0.2 cyc/deg) already after 1.5 h of wearing frosted goggles which cause deprivation myopia, (2) that CA also occurs with negative lenses (-7.4D) and positive lenses (+6.9D) after 1.5 h, at least if accommodation is paralyzed and, (3) that CA occurs at a retinal level or has, at least, a retinal component. Furthermore, we have studied the effects of atropine and reserpine, which both suppress myopia development, on CA. Quisqualate, which causes retinal degeneration but leaves emmetropization functional, was also tested. We found that both atropine and reserpine increase contrast sensitivity to a level where no further CA could be induced by frosted goggles. Quisqualate increased only the variability of refractive development and of contrast sensitivity. Taken together, CA occurring during extended periods of defocus is a possible candidate for a retinal error signal for myopia development. However, the situation is complicated by the fact that there must be a second image processing mode generating a powerful inhibitory growth signal if the image is in front of the retina, even with poor images (Diether, S., & Schaeffel, F. (1999).  (+info)

Correction of Myopia Evaluation Trial (COMET) - Full Text View - ClinicalTrials.govCorrection of Myopia Evaluation Trial (COMET) - Full Text View - ClinicalTrials.gov
Myopia (nearsightedness) is an important public health problem, which entails substantial societal and personal costs. It is highly prevalent in our society and even more frequent in Asian countries; furthermore, its prevalence may be increasing over time. High myopia contributes to significant loss of vision and blindness. At present, the mechanisms involved in the etiology of myopia are unclear, and there is no way to prevent the condition. Current methods of correction require lifelong use of lenses or surgical treatment, which is expensive and may lead to complications. The rationale for this trial, the Correction of Myopia Evaluation Trial (COMET), arises from the convergence of research involving (1) the link between accommodation and myopia in children and (2) animal models of myopia showing the important role of the visual environment in eye growth. A contribution of this research is that blur is a critical component in the development of myopia. The primary aim of COMET, to evaluate the ...

The change in AL/CR progression and spherical equivalent progression may predict the risk of high myopia | IOVS | ARVO JournalsThe change in AL/CR progression and spherical equivalent progression may predict the risk of high myopia | IOVS | ARVO Journals
Purpose : To investigate the axial length and corneal radius of curvature (AL/CR) ratio in high versus low myopes and its relationship with myopia progression. Methods : Baseline AL/CR ratio of the right eyes of 310 high myopes (aged 7 to 16; myopia ≤ -6.00D) from the ZOC-BHVI High Myopia Registry (2012- 2013, Guangzhou, China) and 733 low myopes (aged 6 to 16; myopia -0.50D to -3.50D) from Vision CRC studies (2010-2014, Guangzhou, China) were calculated. Exclusion criteria were ocular disease, surgery or previous treatment for myopia. All participants underwent measurement of axial lengths (AL), corneal radii of curvature (CR) and cycloplegic objective refraction. Low myopes were followed 6 monthly for 12 months. Parental myopia was documented. General linear model was used to test the relationship between AL/CR ratio and spherical equivalent (SE) after adjusting for parental myopia, gender, age, and high versus low myopia. The progression in AL/CR ratio with progression in SE was assessed in ...

THE IMPACT OF MYOPIA AND HIGH MYOPIA - better vision at any age
Measures for the detection and management of myopia ought to be an integral part of plans for the provision of eye-care services. They ought to be part of general health care for vision impairment due to (i) the uncorrected refractive error associated with related to the increased prevalence of myopia; (ii) the pathologic repercussions of myopia.. The term myopic macular degeneration (MMD) should be used scientifically and in research to classify the blinding retinal diseases associated with high myopia. Presently, a number of terms are used, including MMD, myopic maculopathy, myopic retinopathy and myopic choroidal neovascularization.. Epidemiological data are lacking on the occurrence of myopia, high near-sightedness and vision impairment connected with high myopia in Africa, Central America, South America and Oceania. These locations ought to be priorities for future research study.. Interpretations of myopia and high myopia. The medicinal definition of myopia is a condition in which the ...

Study of Myopia Prevention in Children With Low Concentration of Atropine - Full Text View - ClinicalTrials.govStudy of Myopia Prevention in Children With Low Concentration of Atropine - Full Text View - ClinicalTrials.gov
The prevalence rate of myopia is rising rapidly in several Asian countries. A prevalence survey conducted in 1995 of 11178 school children in Taiwan were 12 percent for six year old and 84 percent for teenagers 16 o 18 years. Among them, twenty percent were high myopes. While in the United States and Europe the prevalence rate in older adults is 20% to 50%. The rate of progression of myopia is highest in young children, and the average age of stabilization of myopia is approximately 16 years.The onset of myopia may occur at a relatively young age, leading to higher risks of high myopia (myopia at least 6.0 diopters ) in adulthood. High myopia is associated with potentially blinding complications. Therefore, prevention of myopia progression is important in Taiwan, especially in young children.. There is some evidence that atropine eyedrops retard myopia progression in three randomized clinical trials. It is believed that atropine act on muscarinic receptor located in the sclera and through some ...

Undercorrection of myopia enhances rather than inhibits myopia progression
The effect of myopic defocus on myopia progression was assessed in a two-year prospective study on 94 myopes aged 9{14 years, randomly allocated to an undercorrected group or a fully corrected control group. The 47 experimental subjects were blurred by approximately +0.75 D (blurring VA to 6/12), while the controls were fully corrected. Undercorrection produced more rapid myopia progression and axial elongation (ANOVA, F(1,374)=14.32, p,0.01). Contrary to animal studies, myopic defocus speeds up myopia development in already myopic humans. Myopia could be caused by a failure to detect the direction of defocus rather than by a mechanism exhibiting a zero-point error ...

Myopia and Outdoor Exposures | IOVS | ARVO JournalsMyopia and Outdoor Exposures | IOVS | ARVO Journals
Children are less likely to develop myopia when they are more often outside. Animal models show that bright laboratory lighting (15,000-25,000 lux) slows deprivation myopia (chick, tree shrew, monkey) and negative lens-induced myopia (chick, tree shrew). Long-term exposure for 3 months to bright light in the lab increases retinal dopamine production and release (chicks); and because a dopamine antagonist was found to cancel the effect of bright light on deprivation myopia (chicks), it was proposed that bright light might inhibit myopia development by stimulating dopamine release from the retina. But does bright light in the lab really reflect the natural conditions outside? Stone and colleagues1 have now compared deprivation myopia development in chicks in animal facilities and in real outdoor settings, with variable weather and illuminances. They found disappointingly small and temporary effects on deprivation myopia, and the effects on retinal dopamine were inconsistent-no effect of outdoor ...

The prevalence of myopia in developed countries in East and Southeast Asia has increased to more than 80% in children completing schooling, whereas that of high myopia has increased to 10%-20%. This poses significant challenges for correction of refractive errors and the management of pathological high myopia. Prevention is therefore an important priority. Myopia is etiologically heterogeneous, with a low level of myopia of clearly genetic origins that appears without exposure to risk factors. The big increases have occurred in school myopia, driven by increasing educational pressures in combination with limited amounts of time spent outdoors. The rise in prevalence of high myopia has an unusual pattern of development, with increases in prevalence first appearing at approximately age 11. This pattern suggests that the increasing prevalence of high myopia is because of progression of myopia in children who became myopic at approximately age 6 or 7 because age-specific progression rates typical of ...

Non-Cycloplegic SE Helps Predict Myopia OnsetNon-Cycloplegic SE Helps Predict Myopia Onset
A patients risk of myopia onset can be influenced by various things, including parental myopia, female gender, longer axial length, reduced outdoor time, increased near work time and accommodative insufficiency. Since cycloplegia isnt readily available for most medical practitioners outside of eyecare offices, assessment of spherical equivalent (SE) refraction-commonly used in myopia studies-has limited applicability for other care providers. A recent cohort study observed the performance of SE obtained using non-cycloplegic methods as a predictor of myopia, which would be more accessible across the board for patient assessment. Researchers included 1,022 children aged six to 10 years from two elementary schools in Wenzhou, China. The participants were evaluated at baseline and annual follow-up appointments for three years. The doctors performed non-cycloplegic refraction, ocular biometry and accommodation measurements. A total of 830 of the students were non-myopic at baseline. Two years into ...

Purpose: To investigate the association between serum vitamin D levels and myopia in young adults. Methods: A total of 946 individuals participating in the 20-year follow-up of the Western Australian Pregnancy Cohort (Raine) Study were included in this study. Ethnicity, parental myopia, and education status were ascertained by self-reported questionnaire. A comprehensive ophthalmic examination was performed, including postcycloplegic autorefraction and conjunctival UV autofluorescence photography. Serum 25-hydroxyvitamin D3 (25(OH)D3) concentrations were determined using mass spectrometry. The association between serum 25(OH)D3 concentrations and prevalent myopia was determined using multivariable logistic regression. Myopia was defined as mean spherical equivalent ≤ −0.5 diopters. Results: Of the 946 participants, 221 (23.4%) had myopia (n = 725 nonmyopic). Myopic subjects had lower serum 25(OH)D3 concentrations compared to nonmyopic participants (median 67.6 vs. 72.5 nmol, P = 0.003). In ...

An epidemiological study of the risk factors associated with myopia in young adult men in Korea | Scientific ReportsAn epidemiological study of the risk factors associated with myopia in young adult men in Korea | Scientific Reports
The prevalence of myopia has been increasing worldwide. Its causes are not completely clear, although genetic and environmental factors are thought to play a role. Data were collected by the Korean Military Manpower Administration. Frequency analysis was used for comparisons of general characteristics. Pearsons chi-square tests and logistic regression analysis were used to verify the correlations between possible risk factors and the prevalence of myopia or high myopia. The prevalence of myopia (50.6-53.0%) and high myopia (11.3-12.9%) increased each year. These tended to be the highest in patients born in spring, and decreased in the following order according to education level: 4- or 6-year university education or more, high school education or less, and 2- to 3-year college education. Moreover, the prevalence of myopia and high myopia was significantly higher in patients ≤ 60 kg and with a body mass index ≤ 18.5 kg/m2. The prevalence of high myopia was significantly higher in taller patients (

Common childhood myopia control myths - Myopia Control SingaporeCommon childhood myopia control myths - Myopia Control Singapore
Orthokeratology Lenses are hard contact lenses which are specifically worn overnight during sleep. This method was first developed in the 1960s to correct myopia without glasses.. The Ortho-K Lenses work by temporarily moulding and flattening the corneas shape so light rays entering the eyes are more focused on the retina, this sharpening vision. The user can go about his/her activities the next day without spectacles and glasses, but the effect only lasts for a day and he/she will have to wear the Ortho-K lens again at night to achieve the same effect the next morning.. Therefore, Ortho-K does not actually treat, control nor reduce myopia. It only temporarily reshapes the cornea into a flatter curvature to overcome near-sightedness. Although Ortho-K lenses can be worn for temporary correction for myopia, most ophthalmologists will not recommend Ortho-K lenses as a means of controlling childhood myopia progression.. ...

Progressive (High) Myopia - AAPOSProgressive (High) Myopia - AAPOS
Myopia (near-sightedness) is a condition in which the optical system of the eye causes incoming light rays to focus in front of the retina, instead of focusing directly on the retinal surface. Various factors can cause this abnormal focus of light rays, including abnormalities of the lens or cornea, or by an eye that is abnormally long. Myopia is treated with glasses in younger children or, in some cases, contact lenses in older children and teenagers. Refractive surgery, such as Lasik, is generally reserved for adults except for certain limited studies in children less than 18 years of age. High myopia is generally defined as near-sightedness of -6.00 diopters or higher, and is often associated with a very long eye, termed a long axial length. High myopia generally begins in early childhood, and continued growth of the eye often means that the corrective lens prescription required to allow proper focus may not stabilize until the early adult years. The prevalence of high myopia has been ...

Prevalence and risk factors for myopia in older adult east Chinese population | BMC Ophthalmology | Full TextPrevalence and risk factors for myopia in older adult east Chinese population | BMC Ophthalmology | Full Text
This survey provides the first population-based cross-sectional data on the prevalence of myopia and high myopia and associated risk factors among the older adult in East China. The major finding was that myopia is common in East Chinese resident population with age ≥ 60 years. It indicated that 21.1% subjects had myopia, which was much lower than the rate (41.8%) among Japanese urban population with age ≥ 65 reported in the Tajimi study [18]. However, it was higher than the rate among rural Korean population in the same age group (13.2% in 60-69 years, 15.9% in 70-79 years, and 34.9% in 80+ years) [29]. The prevalence of myopia among older adult population in East China was lower than South China, and approximated North China. Different distribution of myopia in Chinese cities may suggest that environment and lifestyle may play an important role in myopia among older population, except reasons such as differences in ages of subjects included and the examination techniques used in different ...

Mutations in SCO2 are associated with autosomal-dominant high-grade myopia | ScholarBank@NUSMutations in SCO2 are associated with autosomal-dominant high-grade myopia | [email protected]
Myopia, or near-sightedness, is an ocular refractive error of unfocused image quality in front of the retinal plane. Individuals with high-grade myopia (dioptric power greater than -6.00) are predisposed to ocular morbidities such as glaucoma, retinal detachment, and myopic maculopathy. Nonsyndromic, high-grade myopia is highly heritable, and to date multiple gene loci have been reported. We performed exome sequencing in 4 individuals from an 11-member family of European descent from the United States. Affected individuals had a mean dioptric spherical equivalent of -22.00 sphere. A premature stop codon mutation c.157C>T (p.Gln53*) cosegregating with disease was discovered within SCO2 that maps to chromosome 22q13.33. Subsequent analyses identified three additional mutations in three highly myopic unrelated individuals (c.341G>A, c.418G>A, and c.776C>T). To determine differential gene expression in a developmental mouse model, we induced myopia by applying a -15.00D lens over one eye. Messenger ...

Dealing With Degenerative Myopia - optometrist.com.auDealing With Degenerative Myopia - optometrist.com.au
Most people do not take Myopia seriously. After all, it is a common vision problem. This condition, (also called nearsightedness or short-sightedness), involves having blurred vision when looking at things far from you while objects near you appear clear. This is assuming you are not wearing glasses or contact lenses.. Perhaps, the notion of myopia as a relatively safe eye condition comes from the fact that most cases improve as one ages, especially with the help of eye glasses or contact lenses. However, very few people know that myopia can actually be a serious problem that can cause vision loss. Read on to learn more about this condition.. Degenerative Myopia. This condition is more severe than other types of nearsightedness. It is associated with changes in the retina and the macula. It progresses rapidly and it can cause severe vision loss and retinal detachment.. Degenerative myopia is believed to be hereditary and is present from the time of birth. Most of the time, however, its symptoms ...

RePub, Erasmus University Repository: The causes and consequences of childhood myopiaRePub, Erasmus University Repository: The causes and consequences of childhood myopia
Myopia is the eye disorder with the most rapid increase in prevalence worldwide. It develops in childhood with a peak incidence between 13-15 years. Especially high myopia, a refractive error of -6 diopters or more, increases the risk of permanent visual impairment during adulthood due to structural abnormalities of the retina and optic nerve. The causes of myopia are complex. Lifestyle factors in childhood, such as time spent outdoors and close work are risk factors. Moreover, genetic studies have revealed more than many factors associated with myopia. Pharmacological and optical interventions to inhibit myopia progression are becoming increasingly common. The ultimate goal of this thesis was to gain insight into the causes and consequences of childhood myopia. For this purpose we investigated the environmental and genetic factors of myopia, eye growth in children and ocular biometry development in subjects of the Generation R and ALSPAC study. We studied the consequences of high myopia on ...

Progressive Myopia: When Your Childs Vision Keeps Getting WorseProgressive Myopia: When Your Childs Vision Keeps Getting Worse
Myopia is a refractive error that happens when the eye focuses incoming light in front of the retina, rather than directly on it, resulting in blurred distance vision. While an exact cause of progressive myopia is not known, most research indicates that a combination of environmental and genetic factors trigger the condition. First of all, there is evidence that a family history of nearsightedness is a contributing factor. Additionally, spending a lot of time indoors may play a role in myopia development, as studies show that children who spend more time outside have less incidence of myopia. Lastly, near point stress, which can be caused from looking at a near object for an extended period of time, can prompt the eye to grow longer and result in myopia. Several eye doctors recommend following the 20-20-20 rule when using digital devices (stopping every 20 minutes to look 20 feet away for 20 seconds) to reduce near point stress caused by computer use. ...

What Is Myopia Control?. Although an outright cure for nearsightedness has not been discovered, Bellevue Vision Clinic can now offer a number of treatments that may be able to slow the progression of myopia.. ​. These treatments can induce changes in the structure and focusing of the eye to reduce stress and fatigue associated with the development and progression of nearsightedness.. ​. Why should you be interested in myopia control? Because slowing the progression of myopia may keep your child from developing high levels of nearsightedness that require thick, corrective eyeglasses and have been associated with serious eye problems later in life, such as early cataracts or even a detached retina. ...

Oh my - myopia! Should I be worried? - Pediatric Eye Associates, LLC
Myopia is also called nearsightedness. It means that you cannot see long distances without the help of glasses or contact lenses (refractive lenses). On the other hand, you have no trouble seeing objects up close in focus. Myopia is caused by changes to the shape of the eye globe - specifically elongation or lengthening. This impairs the eyes ability to properly focus light that is being projected on the retina. Instead of focusing it right at the retina, it focuses it in front of the retina. Myopias sister - hyperopia, or farsightedness - is the opposite. Because the eye globe is shortened, the light focuses behind the retina.. Children whose parents have myopia are more likely to develop it, but it isnt a cause-and-effect situation. Some childrens ophthalmologists suspect that screen use has something to do with the rise in diagnosis rates, as well. If you suspect your child may have myopia, look for these symptoms:. ...

Purpose: To determine the effects of intravitreal atropine on scleral growth in the form-deprived chick as an experimental model of myopia. Methods: Five groups of five chicks were studied from day 0-12 post-hatching. One group remained untreated (C), and four were form-deprived by monocular light diffusers to induce myopia. Two groups (RL and A) wore diffusers for 9 days, and the other two groups (D and D + A) wore diffusers throughout the study. Group D received no further treatment (myopia positive control). Groups A and D + A received intravitreal injections of atropine for days 9-12. Measurements of refractive error and axial length were performed on days 0, 9, and 12. Sclera changes were assessed in cartilaginous and fibrous layers by histological analysis. Results: All form-deprived eyes had a myopic refractive error on day 9. All atropine- treated groups were hyperopic on day 12. The effect of atropine was most evident in Group D + A in which diffusers were maintained throughout ...

Myopia: A public health crisis in waiting | Points de Vue | International Review of Ophthalmic OpticsMyopia: A public health crisis in waiting | Points de Vue | International Review of Ophthalmic Optics
Both environmental and genetic factors are thought to contribute to the onset and progression of myopia, but it has been suggested that environmental factors have a larger role to play in the rapid increase in the prevalence of myopia. A heavily indoor and near-activity based lifestyle,[16, 17] with less time outdoors,[18] combined with the intense education commencing at very young ages, as occurring in many East Asian countries, are major contributing factors.[16] Evidence is now growing to support the use of interventions in slowing myopia progression. Optical interventions that modulate the visual feedback and environmental interventions promoting increased outdoor time can successfully delay and slow the progress of myopia in an individual. Optical strategies shown to slow the progress of myopia include ortho-K (30% to 57%),[19, 20] multifocal-type soft contact lenses (25% to 72%),[20] and executive bifocals (39% to 51%).[21] Progressive addition spectacles are limited to 15% to 20%.[21] ...

How Multifocal Lenses Slow Down Myopia : Schaeffer Eye Center
What causes myopia?. Myopia develops when the eye exhibits unusual structural issues. In some children, the problem might arise if the cornea, which helps incoming light focus at a single point, is overly curved. Other children might have longer than average eyes. A naturally healthy eye assumes a nearly perfectly round shape, but a longer eye makes it more difficult for light to converge at the retina as needed for clear vision.. Why does myopia in children worsen with age?. Children with myopia tend to experience a progressive deterioration of their vision until adulthood. The growing process characteristic of childhood affects many bodily organs, including the eyes. As a result, the eyes may change, making myopia worse. Once the eyes stop their growth, which may not happen until early adulthood, the severity of a persons myopia may begin to stabilize ...

Myopia ControlMyopia Control
The CDC now recognizes progressive myopia (near-sightedness) as an epidemic. There is research to suggest the rapid increase in near-sightedness in the world is related to children spending more time doing near activities (reading, studying, playing computer work) and less time playing outdoors. In addition to increasing outdoor play time, there are medical treatments available to slow down the development of myopia. One such treatment is called ortho-keratology (ortho-k). Ortho-k is a non-surgical procedure that eliminates the need for daytime glasses or contact lenses. It improves vision by gently reshaping the cornea while you sleep. Best of all, this technology has been shown to decrease the rate of myopia development in children. Call the office to learn more about ortho-keratology and other methods of controlling near-sightedness.. ...

Topical Atropine for Myopia Management: The Latest Research - Review of Myopia Management
Visiting Research Scientist, Brien Holden Vision Institute. A network meta-analysis on myopia control found that use of atropine at different concentrations was significantly superior to other interventions (for example, progressive addition spectacle lenses, multifocal soft contact lenses, orthokeratology, more outdoor activities, etc.)1 Other reviews and meta-analysis similarly concluded that there was less myopic progression with atropine and that both the efficacy and adverse effects were dose-dependent.2, 3. Atropine is a non-selective muscarinic acetylcholine receptor antagonist (mAchR), and the underlying mechanisms by which it controls myopia progression remain unclear. Initially, it was thought that the drug acted via accommodative mechanisms. Later evidence suggested that the mechanism was via non-accommodative pathways,4 with some reports suggesting that atropine exerted its action via retinal amacrine cells and dopamine; when atropine binds to mAchR on the cells, they could release ...

Myopia in animals - WikipediaMyopia in animals - Wikipedia
Some animals suffer from shortsightedness and have poor eyesight. In domestic animals, myopia, with or without astigmatism, occurs frequently. Whereas the rhinoceros may suffer from less-than-adequate eyesight, it generally survives by concentrating with its superior hearing and sense of smell. Some reports, however state that it can see better when focusing with one eye, particularly when walking, posturing, and combatting. Myopia, with or without astigmatism, is the most common eye condition in horses. Several types of occlusion myopia have been recorded in tree shrews, macaques, cats and rats, deciphered from several animal-inducing myopia models. Preliminary laboratory investigations using retinoscopy of 240 dogs found myopic problems with varying degrees of refraction errors depending on the breed. In cases involving German Shepherds, Rottweilers and Miniature horses, the refraction errors were indicative of myopia. Nuclear sclerosis of the crystalline lens was noticed in older dogs. ...

Light exposure and childhood myopia | Points de Vue | International Review of Ophthalmic OpticsLight exposure and childhood myopia | Points de Vue | International Review of Ophthalmic Optics
Over the years, a range of different environmental factors have been proposed as potentially playing a role in human myopia development, with factors related to near-work, education and academic achievement being a major focus of many studies.[6] More recently, perhaps spurred on by the sometimes equivocal findings of studies examining the association between myopia and near work, a shift in the focus of refractive error research has occurred, with a move away from traditional near work measures and a broader focus on additional potential environmental factors (e.g. outdoor activities).[7] Evidence has been emerging from both human epidemiological studies, and research with animals, that ambient light exposure may be an important additional environmental factor that plays a role in myopia. Animal studies demonstrate that normal eye growth appears to be influenced by environmental light levels, since rearing young chickens in dim ambient light environments has been shown to result in more rapid ...

In the BLINK trial in almost 300 children, commercially available center-distance soft multifocal contact lenses with a high add power slowed myopia progression by 0.45 D and eye growth by 0.23 mm compared with single-vision contact lenses, and slowed myopia progression by 0.29 D and eye growth by 0.16 mm compared with medium add power multifocal contact lenses over 3 years, according to Jeffrey J. Walline, OD, PhD, of The Ohio State University College of Optometry in Columbus, and co-authors.. The high add power did not clinically alter the ability to see or result in a greater number of adverse events, they wrote in JAMA.. Wallines group explained that in American children, myopia typically begins between ages 8 and 10 years, with progression into the mid-teen years. Myopia is associated with sight-threatening ocular sequelae, such as cataracts, retinal detachment, glaucoma, and choroidal atrophy. Effective myopia control measures should therefore be implemented to reduce the risks ...

TY - JOUR. T1 - Laser vision correction in treating myopia. AU - Ehlke, Germano Leal. AU - Krueger, Ronald R.. PY - 2016/1/1. Y1 - 2016/1/1. N2 - Myopia is a generally benign refractive error with an increasing prevalence worldwide. It can be corrected temporarily with glasses and contact lenses and permanently with laser vision correction. The 2 main procedures currently being performed formyopia correction are photorefractive keratectomy and laser-assisted in situ keratomileusis. Each technique has its advantages, but they appear to yield similar visual outcomes 1 year after surgery. Laser vision correction for myopia was considered a paradigm shift because healthy eyes could now undergo a surgical procedure to permanently and safely correct the error by altering the center of the cornea, which was previously off limits because of the potential for loss of transparency. Customized ablation using wavefront aberrometry and its optimized profiles were created to correct higher-order aberrations ...

Myopia, also called near-sightedness or short-sightedness, is one of the most commonly occurring eye problems in children and adolescents. Early detection and treatment of initial myopia is associated with better outcomes of visual improvement and correction. Myopia is usually managed by wearing glasses and/or contact lenses. It is common practice for traditional Chinese medicine practitioners to use acupuncture for the treatment of myopia. Acupuncture is the stimulation of acupuncture points by needle insertion, acupressure, surface electrical and laser stimulation. This review aimed to assess the effectiveness and safety of acupuncture in slowing the progression of myopia in children and adolescents. We included two studies conducted in Taiwan with a total of 131 school children and did not combine the results as the two trials assessed different outcomes. One study found no significant difference in changes in the length of the eyes. Both studies found several children experienced mild pain ...

There is no way to prevent nearsightedness. Reading and watching television do not cause nearsightedness. In the past, dilating eye drops were proposed as a treatment to slow the development of nearsightedness in children, but they have never been proven effective.. The use of glasses or contact lenses does not affect the normal progression of myopia - they simply focus the light so the nearsighted person can see distant objects clearly. Hard contact lenses will sometimes hide the progression of nearsightedness, but vision will still get worse under the contact lens.. ...

Myopia « A Brief History…Myopia « A Brief History…
A couple of interesting articles about the increasing incidence of myopia in children.. Myopia isnt an infectious disease, but it has reached nearly epidemic proportions in parts of Asia. In Taiwan, for example, the percentage of 7-year-old children suffering from nearsightedness increased from 5.8 percent in 1983 to 21 percent in 2000. An incredible 81 percent of Taiwanese 15-year-olds are myopic.. The first thought is that this is an Asian genetic thing. It isnt.. In 2008 orthoptics professor Kathryn Rose found that only 3.3 percent of 6- and 7-year-olds of Chinese descent living in Sydney, Australia, suffered myopia, compared with 29.1 percent of those living in Singapore. The usual suspects, reading and time in front of an electronic screen, couldnt account for the discrepancy. The Australian cohort read a few more books and spent slightly more time in front of the computer, but the Singaporean children watched a little more television. On the whole, the differences were small and ...

Three clinical trials in East Asia have demonstrated that raising the amount of time kids spend outside at college lessens the possibility of myopia. Australia has obviously lower levels of myopia using a lifestyle which emphasises outside activities. Young kids report spending just two to three hours every day out, not counting time outside at college. But, there are powerful barriers to accomplishing this benchmark in places where spending time outside is regarded as a diversion from research.. Policy answers must therefore also plan to impede the development of myopia, the occurrence where moderate to moderate myopia gets more intense during youth. Theres currently controversy over if time outside slows development, but powerful seasonal effects on development suggest it may.. School regimes that give a decent place to time outside can reduce both the start and development of myopia.

Myopia (Nearsightedness). If you have myopia you can clearly see close objects, but distant objects are blurry. Myopia is caused by the eyeball being too long. Myopia occurs in different degrees from minimal to extreme. The more myopic you are the blurrier your vision is at a distance and objects will have to be closer to you so you can see them clearly.. Hyperopia (farsightedness). If you have hyperopia, you can see distant objects clearly, but close ones are blurry. Hyperopia occurs when the eyeball is too short for the light rays to focus clearly on the retina.. Astigmatism. If you have an astigmatism, the surface of the eye (cornea) is not perfectly round, rather it is more oval and doesnt allow the eye to focus clearly. The cornea is very important in helping the eye focus light rays on the retina. Astigmatism rarely occurs alone. It is usually accompanies myopia or hyperopia.. Presbyopia. If you have presbyopia, you have the loss of the ability to focus up close that occurs as you age. ...

Facts About Myopia - Paragon Vision Sciences
For many, the term nearsightedness evokes an image of a school-aged child wearing glasses to correct a common condition so they can clearly see a blackboard. But in areas such as East Asia rates of myopia are disturbingly high. Studies in Taiwan have shown that 93% of 18-year-old girls there are myopic.7 In Singapore around 70% of college graduates have the condition8 and in China, a country of well over one billion people, studies have shown rates as high as 78% among 15-year-old children living in urban areas.9 In the US the prevalence has increased markedly in the last 30 years - from 25% in the early 1970s, among those aged 12 to 54 years, to over 40% now.10. Since 2003, Brien Holden Vision Institute with collaborators through the Vision CRC, have been developing methods using an optical device to slow the growth of the myopic eye and reduce the risk of progressing to high levels of myopia.

The cornea is a part of the eye that helps focus light to create an image on the retina. It works in much the same way that the lens of a camera focuses light to create an image on film. The bending and focusing of light is also known as refraction. Usually the shape of the cornea and the eye are not perfect and the image on the retina is out-of-focus (blurred) or distorted. These imperfections in the focusing power of the eye are called refractive errors. There are three primary types of refractive errors: They are myopia, hyperopia and astigmatism. Persons with myopia, or nearsightedness, have more difficulty seeing distant objects as clearly as near objects. Persons with hyperopia, or farsightedness, have more difficulty seeing near objects as clearly as distant objects.

It was more negative, or less positive, for the myopic group than for the emmetropic group (Aa, Ba). The most prominent differences between the two groups were seen in the vertical C 3 −1 (Ab, Bb) and horizontal C 3 1 coma (Ac, Bc) coefficients, both of which tended to be relatively large in comparison to the other higher-order coefficients. Vertical coma C 3 −1 increased linearly from the superior to the inferior visual field and horizontal coma C 3 1 increased from the nasal to the temporal visual field. Emmetropes had slightly ...

Refraction and keratometry in 40 week old premature (corrected age) and term infants | British Journal of OphthalmologyRefraction and keratometry in 40 week old premature (corrected age) and term infants | British Journal of Ophthalmology
The increasing survival rate of premature infants has led to an increase in long term ocular problems, such as ROP and its sequelae-refractive errors, strabismus, and amblyopia.4-22,30,31. Myopia is a common finding in premature infants, and its incidence increases with lower gestational age and the severity of ROP.15-25,28-33 Holmström et al8 pointed out that even in premature infants without ROP, the risk of myopia and anisometropia is higher than in full term infants: the overall incidence of myopia in their preterm babies was 8% at the corrected age of 6 months and 10% at 30 months. The rate of occurrence of myopia was higher in eyes with ROP than eyes without, and higher in the more premature infants.. Choi et al15 and Lue et al19 reported that in premature infants, myopia begins to appear at 6 months of age and increases in severity between ages 6 months and 3 years. Eyes with ROP are more susceptible to a dramatic change in refractive status after 6 months of age, with no further ...

Monbiots Money Myopia | Climate ResistanceMonbiot's Money Myopia | Climate Resistance
The increasingly cosy relationship between government, industry and the Academy (wed throw activism in there, too) is certainly a problem. But thats not to say Monbiot is entirely right.. First, his article is notable for what it leaves out. He could have added: Why is the Economic and Social Science Research Councils Centre for Climate Change Economics and Policy (CCCEP) chaired by the vice-president of a firm offering carbon-finance products? Or why is the Committee on Climate Change (CCC) chaired by a businessman and green activist?. Second, this linear model of research that Monbiot complains about is also remarkably attractive to those at the top of institutional environmentalism. We reported, for example, on Sir David Kings advocacy for just such a linear model of research funding when he argued that the money spent on the Large Hadron Collider would be better spent saving the climate.. Moreover, since Lord Sterns report on the economics of climate change, the economic impact part ...

Retina6
  • The main vision-threatening complication in high myopia is myopic maculopathy, in which the retinal pigment epithelium (RPE) and choroid beneath the neural retina become severely atrophic, resulting in atrophy of the whole retina and choroid at the macula, the center part of the posterior pole in the eyeball. (nature.com)
  • Eyeglasses or contact lenses may help to correct or improve myopia by adjusting the focusing power to the retina. (stlouischildrens.org)
  • The lens is a multi-zone soft contact lens which provides clear vision and at the same time projects blurred, out-of-focus (defocused) images onto the retina to slow down excessive eye growth in myopia. (tmcnet.com)
  • Studies link myopia as a precursor to other more serious eye conditions like cataracts, myopic macular degeneration, glaucoma and detachment of the retina. (visualtasktips.com)
  • In a worst-case scenario, early myopia can lead to the emergence of progressive myopia, a severe form of short-sightedness: after the onset, a person's vision may quickly deteriorate at a rate of one diopter per year and turn into high myopia, which increases the risk of other eye problems, such as damage to the retina or even blindness 6 .
