A series of tests used to assess various functions of the eyes.
Type of vision test used to determine COLOR VISION DEFECTS.
Defects of color vision are mainly hereditary traits but can be secondary to acquired or developmental abnormalities in the CONES (RETINA). Severity of hereditary defects of color vision depends on the degree of mutation of the ROD OPSINS genes (on X CHROMOSOME and CHROMOSOME 3) that code the photopigments for red, green and blue.
Relatively bright light, or the dazzling sensation of relatively bright light, which produces unpleasantness or discomfort, or which interferes with optimal VISION, OCULAR. (Cline et al., Dictionary of Visual Science, 4th ed)
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).
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.
The ability to detect sharp boundaries (stimuli) and to detect slight changes in luminance at regions without distinct contours. Psychophysical measurements of this visual function are used to evaluate visual acuity and to detect eye disease.
The process in which light signals are transformed by the PHOTORECEPTOR CELLS into electrical signals which can then be transmitted to the brain.
Vision considered to be inferior to normal vision as represented by accepted standards of acuity, field of vision, or motility. Low vision generally refers to visual disorders that are caused by diseases that cannot be corrected by refraction (e.g., MACULAR DEGENERATION; RETINITIS PIGMENTOSA; DIABETIC RETINOPATHY, etc.).
The blending of separate images seen by each eye into one composite image.
Function of the human eye that is used in dim illumination (scotopic intensities) or at nighttime. Scotopic vision is performed by RETINAL ROD PHOTORECEPTORS with high sensitivity to light and peak absorption wavelength at 507 nm near the blue end of the spectrum.
Images seen by one eye.
The inability to see or the loss or absence of perception of visual stimuli. This condition may be the result of EYE DISEASES; OPTIC NERVE DISEASES; OPTIC CHIASM diseases; or BRAIN DISEASES affecting the VISUAL PATHWAYS or OCCIPITAL LOBE.
Mental processing of chromatic signals (COLOR VISION) from the eye by the VISUAL CORTEX where they are converted into symbolic representations. Color perception involves numerous neurons, and is influenced not only by the distribution of wavelengths from the viewed object, but also by its background color and brightness contrast at its boundary.
Persons with loss of vision such that there is an impact on activities of daily living.
The total area or space visible in a person's peripheral vision with the eye looking straightforward.
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.
The selecting and organizing of visual stimuli based on the individual's past experience.
Devices that help people with impaired sensory responses.
The difference between two images on the retina when looking at a visual stimulus. This occurs since the two retinas do not have the same view of the stimulus because of the location of our eyes. Thus the left eye does not get exactly the same view as the right eye.
Photosensitive afferent neurons located primarily within the FOVEA CENTRALIS of the MACULA LUTEA. There are three major types of cone cells (red, blue, and green) whose photopigments have different spectral sensitivity curves. Retinal cone cells operate in daylight vision (at photopic intensities) providing color recognition and central visual acuity.
Investigative technique commonly used during ELECTROENCEPHALOGRAPHY in which a series of bright light flashes or visual patterns are used to elicit brain activity.
A nonspecific term referring to impaired vision. Major subcategories include stimulus deprivation-induced amblyopia and toxic amblyopia. Stimulus deprivation-induced amblyopia is a developmental disorder of the visual cortex. A discrepancy between visual information received by the visual cortex from each eye results in abnormal cortical development. STRABISMUS and REFRACTIVE ERRORS may cause this condition. Toxic amblyopia is a disorder of the OPTIC NERVE which is associated with ALCOHOLISM, tobacco SMOKING, and other toxins and as an adverse effect of the use of some medications.
Social welfare organizations with programs designed to assist individuals in need.
Advanced technology that is costly, requires highly skilled personnel, and is unique in its particular application. Includes innovative, specialized medical/surgical procedures as well as advanced diagnostic and therapeutic equipment.
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.
Eating an excess amount of food in a short period of time, as seen in the disorder of BULIMIA NERVOSA. It is caused by an abnormal craving for food, or insatiable hunger also known as "ox hunger".

Characteristics of discrepancies between self-reported visual function and measured reading speed. Salisbury Eye Evaluation Project Team. (1/745)

PURPOSE: Visual impairment is a risk factor for morbidity in the elderly and is often screened for by self-report. This study evaluates whether there are subsets for whom there is a discrepancy between self-reported and measured function. METHODS: The prevalence of a discrepancy between self-reported difficulty reading a newspaper and measured reading speed was determined in 2520 community-based men and women, aged 65 to 84 years, and the discrepant group characterized by polychotomous regression. RESULTS: Of subjects who reported minimal difficulty reading a newspaper, 10.8% (227/2107) read newsprint-sized text (0.21 degrees) more slowly than 80 words/min, a level previously shown to be necessary for sustained reading. Poor visual acuity, presence of psychiatric symptoms, and less satisfaction with vision were associated with being in the group that read slowly and reported difficulty with reading. Better cognition, better visual acuity, more years of education, white race, and fewer psychiatric symptoms were associated with being in the group that read more quickly and reported minimal difficulty. When reading the text size at which subjects read their fastest, only 2.6% of those with minimal difficulty remained discrepant. These individuals were more likely to have less education, be male, be African American, and have poorer cognitive status than those who did not remain discrepant. CONCLUSIONS: A subset of the elderly population have a substantial discrepancy between self-reported reading difficulty and measured reading speed. In some, this discrepancy may be based on underlying expectations and experiences, and in others it may represent a transition from no visual impairment to visual impairment.  (+info)

Tonic accommodation, age, and refractive error in children. (2/745)

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)

Visual function in term infants with hypoxic-ischaemic insults: correlation with neurodevelopment at 2 years of age. (3/745)

AIMS: To determine if there is any association between the findings of visual assessment performed at the age of 5 months and neurodevelopmental outcome at the age of 2 years in children who have sustained hypoxic-ischaemic insults. METHODS: Twenty nine term infants with hypoxic-ischaemic encephalopathy and/or brain lesions on neonatal magnetic resonance imaging (MRI) were prospectively evaluated. At 5 months of age all the infants had their visual function assessed using the Atkinson Battery of Child Development for Examining Functional Vision, which includes the assessments of optokinetic nystagmus (OKN), acuity, visual fields, fixation shift and phase and orientation reversal visual evoked potentials. At 2 years of age the children had a structured neurological evaluation and a Griffiths developmental assessment. RESULTS: There was good correlation between the extent of the early detected visual impairment and both neuromotor and global development. Children with more than three out of five abnormal visual tests at 5 months of age tended to have abnormal neurological examination results and abnormal developmental quotients. Children with three or fewer abnormalities tended to have developmental quotients in the normal range; the level of their performance, however, was still related to the number of visual tests passed. CONCLUSIONS: Individual visual tests can provide important prognostic information. While abnormal OKN and acuity were always associated with abnormal outcome, normal results on visual evoked potentials and fixation shift tended to be associated with normal outcome.  (+info)

Off-axis monochromatic aberrations estimated from double pass measurements in the human eye. (4/745)

Off-axis monochromatic aberrations in the human eye impose limits on peripheral vision. However, the magnitude of the aberrations off-axis, and in particular coma, has not been yet completely determined. We have developed a procedure to estimate third order aberrations in the periphery of the human eye. The technique is based on recording series of double pass retinal images with unequal entrance and exit pupil diameters (Artal, Iglesias, Lopez-Gil & Green (1995b). J. Opt. Soc. Am. A, 12, 2358-2366.) which allows the odd asymmetries in the retinal image be assessed. The procedure that is described provides accurate estimates of the main off-axis aberrations: astigmatism, defocus and coma. We have measured these aberrations in four normal subjects. For a given eccentricity, the measured amount of coma and astigmatism are relatively similar among subjects, because the angular distance from the axis is the dominant factor in determining the magnitude of these aberrations. However, we found considerable variability in the values of peripheral defocus, probably due to a complicate combination of off-axis aberrations and fundus shape. The final off-axis optical performance of the eye for a given object location is determined by a particular mixture of defocus, astigmatism, coma and higher order aberrations.  (+info)

The Bristol Shared Care Glaucoma Study: reliability of community optometric and hospital eye service test measures. (5/745)

BACKGROUND/AIMS: Primary open angle glaucoma patients and glaucoma suspects make up a considerable proportion of outpatient ophthalmological attendances and require lifelong review. Community optometrists can be suitably trained for assessment of glaucoma. This randomised controlled trial aims to assess the ability of community optometrists in the monitoring of this group of patients. METHODS: Measures of cup to disc ratio, visual field score, and intraocular pressure were taken by community optometrists, the hospital eye service and a research clinic reference "gold" standard in 405 stable glaucoma patients and ocular hypertensives. Agreement between and within the three centres was assessed using mean differences and intraclass correlation coefficients. Tolerance limits for a change in status at the level of individual pairs of measurements were also calculated. RESULTS: Compared with a research clinic reference standard, measurements made by community optometrists and those made in the routine hospital eye service were similar. Mean measurement differences and variability were similar across all three groups compared for each of the test variables (IOP, cup to disc ratio, and visual field). Overall, the visual field was found to be the most reliable measurement and the cup to disc ratio the least. CONCLUSIONS: Trained community optometrists are able to make reliable measurements of the factors important in the assessment of glaucoma patients and glaucoma suspects. This clinical ability should allow those optometrists with appropriate training to play a role in the monitoring of suitable patients.  (+info)

Interobserver agreement for grating acuity and letter acuity assessment in 1- to 5.5-year-olds with severe retinopathy of prematurity. (6/745)

PURPOSE: To evaluate interobserver test-retest reliability of the Teller Acuity Card procedure for assessment of grating acuity at ages 1, 2, 3.5, 4.5, and 5.5 years, for HOTV letter acuity at 3.5 and 4.5 years, and for Early-Treatment Diabetic Retinopathy Study (ETDRS) letter acuity at 5.5 years in the multicenter study of Cryotherapy for Retinopathy of Prematurity (CRYO-ROP). METHODS: Subjects were the 73 participants in the CRYO-ROP study who had acuity assessed at one or more ages by two of the seven study visual acuity testers as part of a quality control procedure. All subjects had birth weights of less than 1251 g, and all had severe (threshold) ROP in one or both eyes. RESULTS: For sighted eyes, interobserver agreement for grating acuity (across all five test ages) was 0.5 octave or better in 57% of eyes and 1.0 octave or better in 85% of eyes. Interobserver agreement for letter acuity (3.5-, 4.5-, and 5.5-year test ages) was 0.5 octave or better in 71% of eyes and 1.0 octave or better in 93% of eyes. For all eyes (sighted and blind), Kendall rank correlation coefficients (Tau) were 0.86, 0.83, and 0.94 for grating, HOTV, and ETDRS acuity, respectively. Kappa statistics on data from all eyes indicated excellent interobserver agreement for grating, HOTV, and ETDRS acuity (0.73, 0.80, and 0.84, respectively). Interobserver agreement was not related to age or to severity of retinal residua of ROP. CONCLUSIONS: Excellent interobserver agreement for grating acuity measurements and for letter acuity measurements was obtained. Results suggest that with careful training and implementation of quality control procedures, high reliability of visual acuity results is possible in clinical populations of young children.  (+info)

RPGR transcription studies in mouse and human tissues reveal a retina-specific isoform that is disrupted in a patient with X-linked retinitis pigmentosa. (7/745)

X-linked retinitis pigmentosa (XLRP) is a genetically heterogeneous group of progressive retinal degenerations. The disease process is initiated by premature apoptosis of rod photoreceptor cells in the retina, which leads to reduced visual acuity and, eventually, complete blindness. Mutations in the retinitis pigmentosa GTPase regulator ( RPGR ), a ubiquitously expressed gene at the RP3 locus in Xp21.1, account for approximately 20% of all X-linked cases. We have analysed the expression of this gene by northern blot hybridization, cDNA library screening and RT-PCR in various organs from mouse and man. These studies revealed at least 12 alternatively spliced isoforms. Some of the transcripts are tissue specific and contain novel exons, which elongate or truncate the previously reported open reading frame of the mouse and human RPGR gene. One of the newly identified exons is expressed exclusively in the human retina and mouse eye and contains a premature stop codon. The deduced polypeptide lacks 169 amino acids from the C-terminus of the ubiquitously expressed variant, including an isoprenylation site. Moreover, this exon was found to be deleted in a family with XLRP. Our results indicate tissue-dependent regulation of alternative splicing of RPGR in mouse and man. The discovery of a retina-specific transcript may explain why phenotypic abberations in RP3 are confined to the eye.  (+info)

Outcome of cataract surgery considering the preoperative situation: a study of possible predictors of the functional outcome. (8/745)

AIM: To analyse possible predictors of the self assessed functional outcome of a cataract extraction. METHODS: The patients' self assessed visual function was studied by use of a questionnaire, the "Catquest", before and 6 months after surgery. All patients (n=1933, mean age 75.5 years, 66.8% women) who were undergoing cataract surgery in March 1995, in 35 different departments of ophthalmology participating in the National Swedish Cataract Register, were included in the study. A routine ophthalmic examination was performed before and after surgery. The following preoperative variables were studied with regard to a possible relation to the outcome: age, sex, ocular comorbidity, best corrected preoperative vision (better eye), first or second eye surgery, other diseases with a need for long term medication, need for home help, need for subsidised travel by taxi. RESULTS: Ocular comorbidity was strongly related to a "no benefit" outcome after surgery (p= 0.005). Second eye surgery and young age was related to a "very good benefit" outcome after surgery (p=0.0001 and p<0.0001 respectively). CONCLUSIONS: Patients with an ocular comorbidity in the eye undergoing a cataract extraction were characterised by a significantly higher frequency of deteriorated self assessed visual function after surgery than patients with no ocular comorbidity. The highest degree of improvement was most frequently found in younger patients undergoing second eye surgery.  (+info)

There are several types of color vision defects, including:

1. Color blindness: This is a common condition where individuals have difficulty distinguishing between certain colors, such as red and green. It is usually inherited and affects males more frequently than females.
2. Achromatopsia: This is a rare condition where individuals have difficulty seeing any colors and only see shades of gray.
3. Tritanopia: This is a rare condition where individuals have difficulty seeing the color blue and only see yellow and red.
4. Deuteranomaly: This is a common condition where individuals have difficulty seeing red and green colors and see these colors as more yellow or orange.
5. Anomalous trichromacy: This is a rare condition where individuals have an extra type of cone in their retina, which can cause unusual color perception.

Color vision defects can be diagnosed with a series of tests, including the Ishihara test, the Farnsworth-Munsell 100 Hue Test, and the Lantern Test. Treatment options vary depending on the type and severity of the condition, but may include glasses or contact lenses, color filters, or surgery.

In conclusion, color vision defects can significantly impact daily life, making it important to be aware of these conditions and seek medical attention if symptoms persist or worsen over time. With proper diagnosis and treatment, individuals with color vision defects can lead normal and fulfilling lives.

Some common types of vision disorders include:

1. Myopia (nearsightedness): A condition where close objects are seen clearly, but distant objects appear blurry.
2. Hyperopia (farsightedness): A condition where distant objects are seen clearly, but close objects appear blurry.
3. Astigmatism: A condition where the cornea or lens of the eye is irregularly shaped, causing blurred vision at all distances.
4. Presbyopia: A condition that occurs as people age, where the lens of the eye loses flexibility and makes it difficult to focus on close objects.
5. Amblyopia (lazy eye): A condition where one eye has reduced vision due to abnormal development or injury.
6. Strabismus (crossed eyes): A condition where the eyes are misaligned and point in different directions.
7. Color blindness: A condition where people have difficulty perceiving certain colors, usually red and green.
8. Retinal disorders: Conditions that affect the retina, such as age-related macular degeneration, diabetic retinopathy, or retinal detachment.
9. Glaucoma: A group of conditions that damage the optic nerve, often due to increased pressure in the eye.
10. Cataracts: A clouding of the lens in the eye that can cause blurred vision and sensitivity to light.

Vision disorders can be diagnosed through a comprehensive eye exam, which includes a visual acuity test, refraction test, and dilated eye exam. Treatment options for vision disorders depend on the specific condition and may include glasses or contact lenses, medication, surgery, or a combination of these.

Low vision is not the same as blindness, but it does affect an individual's ability to perform daily activities such as reading, driving, and recognizing faces. The condition can be treated with low vision aids such as specialized glasses, telescopes, and video magnifiers that enhance visual acuity and improve the ability to see objects and details more clearly.

In the medical field, Low Vision is often used interchangeably with the term "visual impairment" which refers to any degree of vision loss that cannot be corrected by regular glasses or contact lenses. Visual impairment can range from mild to severe and can have a significant impact on an individual's quality of life.

Low Vision is a common condition among older adults, with approximately 20% of people over the age of 65 experiencing some degree of visual impairment. However, Low Vision can also affect younger individuals, particularly those with certain eye conditions such as retinitis pigmentosa or other inherited eye disorders.

Overall, Low Vision is a condition that affects an individual's ability to see clearly and perform daily activities, and it is important for individuals experiencing vision loss to seek medical attention to determine the cause of their symptoms and explore available treatment options.

There are different types of blindness, including:

1. Congenital blindness: Blindness that is present at birth, often due to genetic mutations or abnormalities in the development of the eye and brain.
2. Acquired blindness: Blindness that develops later in life due to injury, disease, or other factors.
3. Amblyopia: A condition where one eye has reduced vision due to misalignment or other causes.
4. Glaucoma: A group of eye conditions that can damage the optic nerve and lead to blindness if left untreated.
5. Retinitis pigmentosa: A degenerative disease that affects the retina and can cause blindness.
6. Cataracts: A clouding of the lens in the eye that can impair vision and eventually cause blindness if left untreated.
7. Macular degeneration: A condition where the macula, a part of the retina responsible for central vision, deteriorates and causes blindness.

There are various treatments and therapies for blindness, depending on the underlying cause. These may include medications, surgery, low vision aids, and assistive technology such as braille and audio books, screen readers, and voice-controlled software. Rehabilitation programs can also help individuals adapt to blindness and lead fulfilling lives.

The amblyopic eye may have reduced visual sharpness and/or abnormal ocular alignment (strabismus). The other eye is generally normal or has better vision. Amblyopia is often present at birth but may not be noticed until the child is a few years old. It can also result from various conditions, such as strabismus, cataracts, or differences in the refractive error of the two eyes (anisometropic amblyopia).

The most common form of amblyopia is anisometropic amblyopia, which occurs when there is a significant difference in the refractive power between the two eyes. This can cause the brain to favor one eye over the other, leading to reduced vision in the amblyopic eye. Amblyopia can be treated with glasses or contact lenses, patching the better eye to force the weaker eye to work harder, or surgery to correct strabismus or anisometropia.

Early detection and treatment are important to prevent long-term visual impairment. However, amblyopia can sometimes persist even after treatment, and it is a leading cause of monocular vision in adults.

Some common signs and symptoms of bulimia include:

* Frequent episodes of binge eating, often accompanied by feelings of guilt, shame, or self-criticism
* Purging behaviors such as vomiting, using laxatives, or excessive exercise to compensate for the binge eating
* Secretive or secretive behavior around eating habits
* Difficulty maintaining a healthy weight due to extreme calorie restriction or purging
* Constipation, bloating, or other gastrointestinal symptoms
* Tooth decay and gum problems from frequent acid exposure
* Hormonal imbalances and menstrual irregularities
* Dehydration, electrolyte imbalances, and other complications from purging
* Social withdrawal, low self-esteem, and other emotional difficulties

Bulimia can be difficult to diagnose, as individuals with the disorder may try to hide their symptoms or deny that they have a problem. However, healthcare professionals can use the following criteria to diagnose bulimia:

* Recurring episodes of binge eating or purging behaviors at least once a week for three months
* Self-evaluation of body shape or weight that is distorted or excessive
* Intense fear of gaining weight or becoming fat
* Denial of the disorder or secrecy around eating habits

If you suspect that someone you know may have bulimia, it's important to approach the situation with sensitivity and support. Encourage them to seek professional help from a mental health provider or a registered dietitian who specializes in eating disorders. With appropriate treatment and support, individuals with bulimia can recover and lead a healthy, fulfilling life.
