Corneal Pachymetry: Measurement of the thickness of the CORNEA.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)Diagnostic Techniques, Ophthalmological: Methods and procedures for the diagnosis of diseases of the eye or of vision disorders.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.Keratoconus: A noninflammatory, usually bilateral protrusion of the cornea, the apex being displaced downward and nasally. It occurs most commonly in females at about puberty. The cause is unknown but hereditary factors may play a role. The -conus refers to the cone shape of the corneal protrusion. (From Dorland, 27th ed)Corneal Edema: An excessive amount of fluid in the cornea due to damage of the epithelium or endothelium causing decreased visual acuity.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)Tomography, Optical Coherence: An imaging method using LASERS that is used for mapping subsurface structure. When a reflective site in the sample is at the same optical path length (coherence) as the reference mirror, the detector observes interference fringes.Encyclopedias as Topic: Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)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.Ocular Hypertension: A condition in which the intraocular pressure is elevated above normal and which may lead to glaucoma.Intraocular Pressure: The pressure of the fluids in the eye.Glaucoma, Open-Angle: Glaucoma in which the angle of the anterior chamber is open and the trabecular meshwork does not encroach on the base of the iris.Tonometry, Ocular: Measurement of ocular tension (INTRAOCULAR PRESSURE) with a tonometer. (Cline, et al., Dictionary of Visual Science, 4th ed)Periodicals as Topic: A publication issued at stated, more or less regular, intervals.Access to Information: Individual's rights to obtain and use information collected or generated by others.Journal Impact Factor: A quantitative measure of the frequency on average with which articles in a journal have been cited in a given period of time.Publishing: "The business or profession of the commercial production and issuance of literature" (Webster's 3d). It includes the publisher, publication processes, editing and editors. Production may be by conventional printing methods or by electronic publishing.Observer Variation: The failure by the observer to measure or identify a phenomenon accurately, which results in an error. Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material).Reproducibility of Results: The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.Pathology: A specialty concerned with the nature and cause of disease as expressed by changes in cellular or tissue structure and function caused by the disease process.Privacy: The state of being free from intrusion or disturbance in one's private life or affairs. (Random House Unabridged Dictionary, 2d ed, 1993)Confidentiality: The privacy of information and its protection against unauthorized disclosure.Computer Security: Protective measures against unauthorized access to or interference with computer operating systems, telecommunications, or data structures, especially the modification, deletion, destruction, or release of data in computers. It includes methods of forestalling interference by computer viruses or so-called computer hackers aiming to compromise stored data.Informed Consent: Voluntary authorization, by a patient or research subject, with full comprehension of the risks involved, for diagnostic or investigative procedures, and for medical and surgical treatment.Genetic Privacy: The protection of genetic information about an individual, family, or population group, from unauthorized disclosure.Internet: A loose confederation of computer communication networks around the world. The networks that make up the Internet are connected through several backbone networks. The Internet grew out of the US Government ARPAnet project and was designed to facilitate information exchange.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.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.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.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)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.Migraine Disorders: A class of disabling primary headache disorders, characterized by recurrent unilateral pulsatile headaches. The two major subtypes are common migraine (without aura) and classic migraine (with aura or neurological symptoms). (International Classification of Headache Disorders, 2nd ed. Cephalalgia 2004: suppl 1)Migraine without Aura: Recurrent unilateral pulsatile headaches, not preceded or accompanied by an aura, in attacks lasting 4-72 hours. It is characterized by PAIN of moderate to severe intensity; aggravated by physical activity; and associated with NAUSEA and / or PHOTOPHOBIA and PHONOPHOBIA. (International Classification of Headache Disorders, 2nd ed. Cephalalgia 2004: suppl 1)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.Glaucoma: An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches. (Dictionary of Visual Science, 4th ed)Glaucoma, Angle-Closure: A form of glaucoma in which the intraocular pressure increases because the angle of the anterior chamber is blocked and the aqueous humor cannot drain from the anterior chamber.Eye Diseases: Diseases affecting the eye.Vision Disorders: Visual impairments limiting one or more of the basic functions of the eye: visual acuity, dark adaptation, color vision, or peripheral vision. These may result from EYE DISEASES; OPTIC NERVE DISEASES; VISUAL PATHWAY diseases; OCCIPITAL LOBE diseases; OCULAR MOTILITY DISORDERS; and other conditions (From Newell, Ophthalmology: Principles and Concepts, 7th ed, p132).Optic Nerve: The 2nd cranial nerve which conveys visual information from the RETINA to the brain. The nerve carries the axons of the RETINAL GANGLION CELLS which sort at the OPTIC CHIASM and continue via the OPTIC TRACTS to the brain. The largest projection is to the lateral geniculate nuclei; other targets include the SUPERIOR COLLICULI and the SUPRACHIASMATIC NUCLEI. Though known as the second cranial nerve, it is considered part of the CENTRAL NERVOUS SYSTEM.Endothelium, Corneal: Single layer of large flattened cells covering the surface of the cornea.Lenses, Intraocular: Artificial implanted lenses.Optometry: The professional practice of primary eye and vision care that includes the measurement of visual refractive power and the correction of visual defects with lenses or glasses.Optic Nerve Diseases: Conditions which produce injury or dysfunction of the second cranial or optic nerve, which is generally considered a component of the central nervous system. Damage to optic nerve fibers may occur at or near their origin in the retina, at the optic disk, or in the nerve, optic chiasm, optic tract, or lateral geniculate nuclei. Clinical manifestations may include decreased visual acuity and contrast sensitivity, impaired color vision, and an afferent pupillary defect.Pressure: A type of stress exerted uniformly in all directions. Its measure is the force exerted per unit area. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Patents as Topic: Exclusive legal rights or privileges applied to inventions, plants, etc.Laser Therapy: The use of photothermal effects of LASERS to coagulate, incise, vaporize, resect, dissect, or resurface tissue.Lens, Crystalline: A transparent, biconvex structure of the EYE, enclosed in a capsule and situated behind the IRIS and in front of the vitreous humor (VITREOUS BODY). It is slightly overlapped at its margin by the ciliary processes. Adaptation by the CILIARY BODY is crucial for OCULAR ACCOMMODATION.Postoperative Period: The period following a surgical operation.Ultraviolet Rays: That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.

Central corneal thickness considered an index of corneal hydration of the UVB irradiated rabbit cornea as influenced by UVB absorber. (1/42)

UVB radiation from sunlight induces an acute corneal inflammation, photokeratitis, accompanied by changes in corneal hydration. We employed a method of ultrasonic pachymetry for daily examination of central corneal thickness as an index of corneal hydration of the rabbit cornea repeatedly irradiated by UVB radiation (312 nm, daily dose of 0.25 J/cm(2) during three or four days) as influenced by UVB absorber (actinoquinol combined with hyaluronic acid) dropped on the ocular surface during irradiation. One day after the third irradiation procedure the animals were sacrificed and corneas examined immuno-histochemically for peroxynitrite formation, a marker of oxidative damage, the antioxidant aldehyde dehydrogenase 3A1 and endothelial nitric oxide synthase, an enzyme generated nitric oxide. Results show that UV absorber combined with hyaluronic acid protected the cornea against UVB-induced changes in corneal thickness and microscopical disturbances to the cornea (both seen after buffered saline application) until the fourth experimental day. These UVB doses are equivalent to a daily exposure of 2.5 hrs of the human cornea to solar UVB radiation for three consecutive days. It is suggested that actinoquinol/ hyaluronic acid drops might be helpful for the human eye in the defence against photooxidative and other oxidative processes.  (+info)

A short-term in vivo experimental model for Fuchs endothelial corneal dystrophy. (5/42)

PURPOSE: We evaluated the in vivo functionality of a corneal endothelium tissue-engineered using corneal endothelial cells from human patients with Fuchs endothelial corneal dystrophy (FECD). METHODS: A total of 15 healthy cats underwent full-thickness corneal transplantation. All transplants were of xenogeneic human origin and all grafts but two were tissue-engineered. In seven animals the graft corneal endothelium was tissue-engineered using cultured corneal endothelial cells from humans with FECD (TE-FECD). Two control animals were grafted with an endothelium engineered using cultured endothelial cells from normal eye bank corneas (TE-normal). Two controls received a native full-thickness corneal transplant, and four other controls were grafted with the stromal carrier only (without endothelial cells). Outcome parameters included graft transparency (0, opaque to 4, clear), pachymetry, optical coherence tomography, endothelial cell morphometry, transmission electron microscopy (TEM), and immunostaining of function-related proteins. RESULTS: Seven days after transplantation, 6 of 7 TE-FECD grafts, all TE-normal grafts, and all normal native grafts were clear (transparency score >3), while all carriers-only grafts were opaque (score <1). The mean pachymetry was 772 +/- 102 mum for TE-FECD, 524 +/- 11 mum for TE-normal, 555 +/- 48 for normal native, and 1188 +/- 223 mum for carriers only. TEM showed subendothelial loose fibrillar material deposition in all TE-FECD grafts. The TE endothelium expressed Na(+)-K(+)/ATPase and Na(+)/HCO3(-). CONCLUSIONS: Restoration of transparency and corneal thickness demonstrated that the TE-FECD grafts were functional in vivo. This novel FECD seven-day living model suggests a potential role for tissue engineering leading to FECD cell rehabilitation.  (+info)

Corneal pachymetry - Wikipedia  Corneal pachymetry - Wikipedia
Corneal pachymetry is the process of measuring the thickness of the cornea. A pachymeter is a medical device used to measure the thickness of the eyes cornea. It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, LRI surgery and is useful in screening for patients suspected of developing glaucoma among other uses. It can be done using either ultrasonic or optical methods . The contact methods, such as ultrasound and optical such as confocal microscopy (CONFOSCAN), or noncontact methods such as optical biometry with a single Scheimpflug camera (such as SIRIUS or PENTACAM), or a Dual Scheimpflug camera (such as GALILEI), or Optical Coherence Tomography (OCT, such as Visante) and online Optical Coherence Pachymetry (OCP, such as ORBSCAN). Corneal Pachymetry is essential prior to a refractive surgery procedure for ensuring sufficient corneal thickness to prevent abnormal bulging of the cornea, a side effect known as ectasia. The instrument used for this ...

Corneal Pachymetry - Medical Clinical Policy Bulletins | Aetna  Corneal Pachymetry - Medical Clinical Policy Bulletins | Aetna
Corneal pachymetry is a non-invasive ultrasonic technique for measuring corneal thickness, and has been used primarily in the evaluation of persons with corneal diseases and in the assessment of persons at risk for glaucoma. Ultrasonic corneal pachymetry is performed by placing an ultrasonic probe on the central cornea, after the cornea has been anesthetized with a topical anesthetic. A technician can operate the pachymeter and it normally takes less than 30 seconds per eye to complete measurements.. The Ocular Hypertension Treatment Study (Kass et al, 2002; Gordon et al, 2002), a prospective randomized controlled clinical trial of glaucoma treatment in persons with elevated intra-ocular pressure (IOP) greater than or equal to 24 mm Hg, found central corneal thickness a statistically significant predictor of development of glaucoma. Corneal thickness was measured only after the study was initiated, and was not used to guide therapy. For the enrolled patients, the Ocular Hypertension Treatment ...

Purpose: To assess reproducibility of central corneal thickness (CCT) measurement by means of ultrasonic pachymetry.. Methods: Fifty one volunteers underwent three sessions of CCT measurements, each consisting of three CCT measurements, performed by each of three different observers. Intra- and interobserver reproducibility was calculated by means of intraclass correlation coefficient (ICC). The expected range of variability between two independent evaluations was calculated using scatter plots of each test-retest difference against their mean. The standard deviation of the mean differences in the test-retest scores was used to describe the differences in the score spread.. Results: The ICC ranges of the intra- and interobserver evaluations were 0.95-0.97 and 0.89-0.95 respectively; the expected variability was ⩽±1% and ⩽± 2% respectively (95% confidence interval).. Conclusions: The measurement of CCT by means of ultrasonic pachymetry is highly reproducible.. ...

The distribution of the CCT values is shown in Figure 1. The mean (SD), median, skewness, and kurtosis of CCT distribution was 530.9 (31.5) μm (range 380-627), 529.0 μm, 0.08, and 0.32, respectively, which suggest a normal distribution. The distributions of CCT for age categories are presented in Table 1. In univariate analysis, a thicker CCT was correlated significantly with a younger age (P , 0.001), higher IOP (P , 0.001), and longer AL (P = 0.003); however, CCT was not associated significantly with ACD (P = 0.087, Table 2). According to the regression line, CCT decreased by 4.0 μm for every decade of life (95% confidence intervals [CI] 2.4-5.5 μm), increased by 2.73 μm for every 1 mm Hg increase in the IOP (95% CI 2.10-3.36 mm Hg), and increased by 2.84 μm for every mm increase in the AL (95% CI 0.98-4.71 μm). When CCTs of male and female subjects were compared, the average CCT in men was 5.8 μm more than that in women (P = 0.001, Table 3). The average CCT in subjects with ...

Reproducible and repeatable objective means to evaluate corneal endothelial morphology and CCT are vital, in both clinical and research settings. Assessment of the endothelium is crucial to determine the suitability of donor corneas, to monitor the outcome of anterior segment procedures, such as cataract surgery, and when evaluating the safety of new intraocular or corneal surgical procedures and intraocular lenses [32, 33]. Thus, assessment and validation of newly developed measurement techniques is essential to determine which techniques can be used interchangeably.. The results of this study indicate that the intra-observer repeatability of ECD, CV, and CCT measurements using z-ring CS4 were not significantly different (p ≥ 0.05). Also, there were no statistically significant differences in intra-observer repeatability for observer 1 of ECD, CV, and CCT measurements with SP-2000P and USP (CCT only). These results indicate a high reliability of repeat testing for ECD, CV, and CCT ...

This work shows that three-dimensional images from MPLSM of endogenous tissue fluorescence can effectively distinguish between normal, precancerous, and cancerous epithelial tissues. The high-resolution capability of MPLSM enabled the identification of three morphologic features (nuclear density ratio, keratin, and epithelial thickness), which showed statistically significant differences between normal and both precancerous and cancerous tissues. Moreover, statistically significant differences were observed in the keratin thickness of dysplasia and both types of SCCs and in the epithelial thickness of dysplasia and CIS. The lack of statistically significant differences in the epithelial thickness of dysplasia and SCCs may be because the imaging depth was limited by signal attenuation in the SCCs, thus underestimating the epithelial thickness in these samples. The statistically significant morphologic changes that accompany precancer and cancer development in the MPSLM images ( Table 1) are ...

Pellucid marginal degeneration - Wikipedia  Pellucid marginal degeneration - Wikipedia
The early stages of pellucid marginal degeneration may also be managed with soft contact lenses.[2] Success has been shown with the use of rigid gas permeable contact lenses combined with over-refraction. People wearing contacts dont report increased problems with glare and contrast sensitivity, but it is not clear if this is due to the corneal disease, or the contact lenses themselves. New studies found that the use of Scleral contact lens, a type of rigid gas permeable (RGP) lens, may be a good option for most people with PMD. Most of these lenses are in the range of 15.5mm to 18.0mm in diameter. Regardless of the lens size, it is thought that the larger the RGP lens will in most cases be more comfortable then standard rigid corneal lenses, and at times more comfortable than soft lenses, regardless of the fact that it is a rigid lens. The highlight to the scleral design and the correction of eye disorders such as pellucid marginal degeneration is that vision with these types of lenses is ...

We describe a bidirectional color Doppler Fourier-domain optical coherence tomography system capable of measuring absolute velocities of moving scatterers by illuminating the sample with two linearly and orthogonally polarized beams, incident at a known angle on the sample. The velocity calculation is independent of the exact orientation of the velocity vector in the detection plane. First measurements were performed on a rotating disk driven at well-defined velocities and tilted by various small angles. Our results indicate a high correlation between preset and calculated velocities (correlation coefficient 0.999) and the independency of these velocities from the tilting angle of the disk. We demonstrate that bidirectional color Doppler optical coherence tomography allows for the measurement of absolute blood flow values in vivo in human retinal vessels.. © 2008 Optical Society of America.

Fuchs Dystrophy Risk Factors | The Eye Clinic of Texas  Fuchs Dystrophy Risk Factors | The Eye Clinic of Texas
Fuchs Dystrophy is a type of corneal disease that affects the inner most layer of the cornea-the endothelium. Fuchs Dystrophy is slowly progressive, is found in both eyes and is slightly more common in women than men. While we can see Fuchs Dystrophy in people in their 30s and 40s, it usually does not compromise vision until people are in their 50s or 60s.. About Fuchs Dystrophy. The endothelial cells are responsible for pumping water out of the cornea and helping to maintain the corneal transparency. While the reason is poorly understood, in Fuchs Dystrophy, the endothelial cells die, which make the endothelium less efficient in its pumping activity. This results in the cornea swelling and distorting vision. Fuchs Dystrophy Risks & Severity. Researchers reporting in the journal Investigative Ophthalmology and Visual Science studied the effects of smoking, and other risk factors, on the development of advanced Fuchs endothelial corneal dystrophy (FECD) and on central corneal thickness ...

0026] The clamping block 40 may include a beveled collar 46 radiating from its outer wall. The beveled collar 46 includes a beveled surface 48 and a flat surface 50. The flat surface 50 is configured to be acted upon by a spacer ring 52, which is, in turn, acted upon by the nut 80 when tightened. The spacer ring 52 is constructed of a rigid material such that it provides a surface against which the nut 80 may slide when rotated thereagainst. The spacer ring 52 thus reduces the degree to which rotational motion of the nut 80 is transmitted to the elastomeric material of the clamping block 40. The beveled surface 48 acts against a corresponding surface the housing 22 to prevent axial movement of the clamping block 40 when the nut 80 is tightened. The beveled surface 48 also transmits axial compression to an inward deformation of the central lumen 42 such that any tool disposed within the central lumen 42 is squeezed by the clamping block 40. Additionally, the central lumen 42 of the clamping block ...

Corneal collagen crosslinking (CXL) was effective at improving the maximum K value, corrected distance visual acuity, and uncorrected distance visual acuity in eyes with cornea ectasia at 1 year post-treatment, according to researchers in a prospective, randomized, multicenter controlled clinical trial. Led by Peter Hersh, MD, the researchers focused on the safety and efficacy of corneal collagen crosslinking to treat corneal ectasia after refractive surgery in 179 subjects. The treatment group had standard CXL compared with riboflavin alone without removal of the epithelium in sham control group patients. The primary efficacy criterion was a change over 1 year of topography-derived maximum keratometry when comparing the two study groups. The maximum K value declined by 0.7 D from baseline to 1 year, compared with a continued progression in the control group (1.3 D difference between treatment and control). The maximum K value decreased by 2.0 D or more in 14 eyes (18%) and by 2.0 D or more in ...

Multiphoton Microscopy of Endogenous Fluorescence Differentiates Normal, Precancerous, and Cancerous Squamous Epithelial...  Multiphoton Microscopy of Endogenous Fluorescence Differentiates Normal, Precancerous, and Cancerous Squamous Epithelial...
This work shows that three-dimensional images from MPLSM of endogenous tissue fluorescence can effectively distinguish between normal, precancerous, and cancerous epithelial tissues. The high-resolution capability of MPLSM enabled the identification of three morphologic features (nuclear density ratio, keratin, and epithelial thickness), which showed statistically significant differences between normal and both precancerous and cancerous tissues. Moreover, statistically significant differences were observed in the keratin thickness of dysplasia and both types of SCCs and in the epithelial thickness of dysplasia and CIS. The lack of statistically significant differences in the epithelial thickness of dysplasia and SCCs may be because the imaging depth was limited by signal attenuation in the SCCs, thus underestimating the epithelial thickness in these samples. The statistically significant morphologic changes that accompany precancer and cancer development in the MPSLM images ( Table 1) are ...

EYE ON TECHNOLOGY - CROSSLINKING-PLUS - EuroTimes  EYE ON TECHNOLOGY - CROSSLINKING-PLUS - EuroTimes
Comparative map before and after CXL-plus (trans-PTK-PRK + accelerated CXL). SCVA improved from 20/50 to 20/25. Epi-off corneal crosslinking (CXL) is a proven treatment for corneal ectatic disease. It halts the ectatic process by strengthening the cornea by means of creating covalent bonds between collagen fibrils. In the last three years many efforts have been made by researchers and ophthalmic companies to improve the quality and the time of treatment through development of new riboflavin solutions and new irradiance protocols.. However, even though the main target of halting corneal ectasia is reached in most cases, few patients affected by moderate to severe keratoconus have a consistent visual acuity (VA) improvement. When performed on its own, the CXL procedure is not intended to improve vision, but rather to stabilise disease, and therefore the patient still remains to be rehabilitated visually, thereby affecting their quality of life. Many face the need to wear customised contact lenses ...

Corneal collagen crosslinking: new hope  Corneal collagen crosslinking: new hope
Results. The first study on crosslinking treatment of keratoconus was performed in 2003 by Wollensak [1]. In this 3-year study, 22 patients with progressive keratoconus were treated with riboflavin and UVA. In all treated eyes, the progression of keratoconus was at least stopped («freezing»). In 16 there also was a slight reversal and flattening of the keratoconus by 2 diopters. Best corrected visual acuity improved slightly in 15 eyes. The 6-year-long term follow-up data of this study including 241 treated eyes again demonstrated a decrease of keratectasia by up to 4.34 dpt after 3 years, a slight increase in visual acuity and improved contact lens tolerance [5]. Two eyes had to be crosslinked twice due to continued progression. These patients had steroid treatment for neurodermitis, however. Other treatment failures were reported in pregnant patients. Apart from that, neither progression of keratectasia nor serious complications have been observed in the Dresden study so far. In CXL, the ...

Keratoconus is a non-infectious eye condition in which the normally round and regular shape of the cornea progressively thins and bulges until it is a cone-like, irregular shape. This cone shape transformation deflects light as it enters the eye, causing substantial vision impairment.. Corneal Collagen Crosslinking* is a relatively pain-free parasurgical treatment for keratoconus that involves the application of riboflavin eye drops to the eye. Crosslinking is performed to slow or stop the progression of Keratoconus and/or ectasia and to postpone or eliminate the need for corneal transplant..

A total of 15 eyes were scanned with the Visante Omni. A lid speculum was used to keep the rabbits eye open during the measurements to ensure that the eyelids did not block the 10-mm diameter mapping area. The cornea was kept wet regularly with balanced salt solution to prevent the ocular surface from drying. First, the cornea was scanned with ATLAS corneal topographer, incorporated with the Visante Omni, where 8000 data points of the anterior corneal surface were recorded. The anterior corneal topography data were then transferred to the Visante OCT station via a network link. The rabbit was then moved to the Visante OCT station to scan for global pachymetry. Pachymetry alignment with anterior corneal surface data, obtained from the ATLAS corneal topographer, required the observer to locate the center of the pupil, which was achieved when the vertex produced a vertical white line behind the center of the cornea. Thereafter, the Visante OCT system would lock onto the vertex and track it so that ...

The percent correct matches were significantly lower in the CH evaluator group compared with each of the other groups. The comparison between AD and RS was also significantly different. The percent correct matches of AD vs. OP and OP vs. RS were both not significantly different. The percent correct matches for only aspheric and established keratoconus topographies or KS topographies alone was also analyzed. When only aspheric and keratoconus topographies were evaluated, the comparisons did not change their pattern, except for OP vs. RS, which was statistically significant. When the analysis included only KS topographies, the percent correct matches decreased in every evaluator group and the CH group was no longer statistically different from AD group, but the difference remained when comparing CH with OP and RS groups. ...

N2 - Purpose: Measurement of normal corneal thickness and corneal epithelial thickness is important in keratorefractive surgery, glaucoma, following extended contact lens wear, and in patients with corneal disease. Clinically, a central corneal thickness less than 500 µm is considered to be moderately-to-extremely thin. The purpose of this study was to compare biological differences in patients with clinically thin compared to normal corneal thickness values in healthy young adults using Fourier domain optical coherence tomography. Patients and methods: In total, 168 eyes from 84 patients aged 19-38 years were scanned using an Avanti optical coherence tomographer. To eliminate circadian effects on corneal thickness, all patients were scanned within a 4-hour window. Corneal thickness was measured across the ...

A port-wine stain is a flat, pink, red, or purple colored birthmark. These are caused by a concentration of dilated tiny blood vessels called capillaries. They usually occur on the head or neck. They may be small, or they may cover large areas of the body. Port-wine stains do not change color when gently pressed and do not disappear over time. They may become darker and thicker when the child is older or as an adult. Port-wine stains on the face may be associated with more serious problems. Skin-colored cosmetics may be used to cover small port-wine stains. The most effective way of treating port-wine stains is with a special type of laser. This is done when the baby is older by a plastic surgery specialist. ...

Entral corneal thickness changes after phacoemulsification by Tanveer Anjum Chaudhry, Muhammad Hamza et al.  "Entral corneal thickness changes after phacoemulsification" by Tanveer Anjum Chaudhry, Muhammad Hamza et al.
Purpose: To determine when the mean central corneal thickness (CCT) returns to normal values after uneventful phacoemulsification. Material and Methods: This was a prospective case series. The study was carried out at the Section of Ophthalmology, Department of Surgery, Aga Khan University Hospital, Karachi. Eyes scheduled to undergo phacoemulsification during December 2011 - March 2012 were eligible to be included. Eyes with corneal degenerations, dystrophies or high pre-op astigmatism were excluded. A structured proforma was used to collect data on sociodemographics, comorbids, visual acuity, and CCT before surgery and 1 day, 1 week and 1 month after surgery. Changes in the mean CCT over time were measured using repeated measures Analysis of Variance (ANOVA) was done. Results: Eighty one eyes were included in the study. The mean (±SD) age of the participants was 58.30 (± 10.04) years. The majority of them (58.0%) were women. Sixty two (76.5%) eyes completed the last follow-up and were included in

Besides optic disc evaluation and visual field testing, the diagnosis of ocular hypertension, primary glaucoma and normal-tension glaucoma is based on an arbitrary IOP cutoff point of 21 mmHg [11]. This cutoff is made on the basis of statistical grounds, principally for screening purpose rather than as a diagnostic criterion. It is nevertheless in clinical use and any factor that changes the estimates of IOP can lead to a misclassification of the patient or predisposed individuals [12].. In this study it was found that the mean CCT and IOP among Ethiopian glaucoma patients were 508.07 μm and 19.46 mmHg respectively. This study also showed a statistically significant association between CCT and IOP. Furthermore, CCT was correlated linearly with IOP values (ρ =0.271, p , 0.001). In this study IOP was manipulated with surgery or medication in some, and not in others, and hence this result should be interpreted cautiously as correlation between baseline untreated IOPs and CCT is much more ...
