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).
Application of tests and examinations to identify visual defects or vision disorders occurring in specific populations, as in school children, the elderly, etc. It is differentiated from VISION TESTS, which are given to evaluate/measure individual visual performance not related to a specific population.
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.
Deviations from the average or standard indices of refraction of the eye through its dioptric or refractive apparatus.
Misalignment of the visual axes of the eyes. In comitant strabismus the degree of ocular misalignment does not vary with the direction of gaze. In noncomitant strabismus the degree of misalignment varies depending on direction of gaze or which eye is fixating on the target. (Miller, Walsh & Hoyt's Clinical Neuro-Ophthalmology, 4th ed, p641)
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.
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.
Perception of three-dimensionality.
The process in which light signals are transformed by the PHOTORECEPTOR CELLS into electrical signals which can then be transmitted to the brain.

The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.
Photosensitive protein complexes of varied light absorption properties which are expressed in the PHOTORECEPTOR CELLS. They are OPSINS conjugated with VITAMIN A-based chromophores. Chromophores capture photons of light, leading to the activation of opsins and a biochemical cascade that ultimately excites the photoreceptor cells.

Test-retest variability of frequency-doubling perimetry and conventional perimetry in glaucoma patients and normal subjects. (1/2067)

PURPOSE: To compare the test-retest variability characteristics of frequency-doubling perimetry, a new perimetric test, with those of conventional perimetry in glaucoma patients and normal control subjects. METHODS: The study sample contained 64 patients and 47 normal subjects aged 66.16+/-11.86 and 64.26+/-7.99 years (mean +/- SD), respectively. All subjects underwent frequency-doubling perimetry (using the threshold mode) and conventional perimetry (using program 30-2 of the Humphrey Field Analyzer; Humphrey Instruments, San Leandro, CA) in one randomly selected eye. Each test was repeated at 1-week intervals for five tests with each technique over 4 weeks. Empirical 5th and 95th percentiles of the distribution of threshold deviations at retest were determined for all combinations of single tests and mean of two tests, stratified by threshold deviation. The influence of visual field eccentricity and overall visual field loss on variability also were examined. RESULTS: Mean test time with frequency-doubling perimetry in patients and normal control subjects was 5.90 and 5.25 minutes, respectively, and with conventional perimetry was 17.20 and 14.01 minutes, respectively. In patients, there was a significant correlation between the results of the two techniques, in the full field and in quadrants, whereas in normal subjects there was no such correlation. In patients, the retest variability of conventional perimetry in locations with 20-dB loss was 120% (single tests) and 127% (mean tests) higher compared with that in locations with 0-dB loss. Comparative figures for frequency-doubling perimetry were 40% and 47%, respectively. Variability also increased more with threshold deviation in normal subjects tested with conventional perimetry. In both patients and normal subjects, variability increased with visual field eccentricity in conventional perimetry, but not in frequency-doubling perimetry. Both techniques showed an increase in variability with overall visual field damage. CONCLUSIONS: Frequency-doubling perimetry has different test-retest variability characteristics than conventional perimetry and may have potential for monitoring glaucomatous field damage.  (+info)

Post-traumatic pituitary apoplexy--two case reports. (2/2067)

A 60-year-old female and a 66-year-old male presented with post-traumatic pituitary apoplexy associated with clinically asymptomatic pituitary macroadenoma manifesting as severe visual disturbance that had not developed immediately after the head injury. Skull radiography showed a unilateral linear occipital fracture. Magnetic resonance imaging revealed pituitary tumor with dumbbell-shaped suprasellar extension and fresh intratumoral hemorrhage. Transsphenoidal surgery was performed in the first patient, and the visual disturbance subsided. Decompressive craniectomy was performed in the second patient to treat brain contusion and part of the tumor was removed to decompress the optic nerves. The mechanism of post-traumatic pituitary apoplexy may occur as follows. The intrasellar part of the tumor is fixed by the bony structure forming the sella, and the suprasellar part is free to move, so a rotational force acting on the occipital region on one side will create a shearing strain between the intra- and suprasellar part of the tumor, resulting in pituitary apoplexy. Recovery of visual function, no matter how severely impaired, can be expected if an emergency operation is performed to decompress the optic nerves. Transsphenoidal surgery is the most advantageous procedure, as even partial removal of the tumor may be adequate to decompress the optic nerves in the acute stage. Staged transsphenoidal surgery is indicated to achieve total removal later.  (+info)

Characteristics of discrepancies between self-reported visual function and measured reading speed. Salisbury Eye Evaluation Project Team. (3/2067)

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)

Space representation in unilateral spatial neglect. (4/2067)

Patients with unilateral brain lesions were given a task requiring exploration of space with the hand in order to assess the visual dependency of unilateral spatial neglect. The task was carried out both without visual control and under visual control. Performances were compared with that of normal subjects. Results were :(1) patients with right brain damage with no visual field defect demonstrated left-sided neglect only when the exploration was not controlled visually; (2) patients with left and right brain damage with visual field defect demonstrated contralateral neglect only when the exploration was under visual guidance. The performance of the patients with right brain damage without visual field defect in not clearly understood. The other results suggest that inner spatial representation remains intact in most cases of spatial neglect. The role of parietal lobe damage in the development of this visually induced phenomenon is hypothesised. The dominant position of vision among the senses is indicated.  (+info)

Cyclic compression of the intracranial optic nerve: patterns of visual failure and recovery. (5/2067)

A patient with a cystic craniopharyngioma below the right optic nerve had several recurrences requiring surgery. Finally the cyst was connected with a subcutaneous reservoir by means of a fine catheter. Symptoms of optic nerve compression recurred more than 50 times during the following year, and were relieved within seconds upon drainage of the reservoir. In each cycle, a drop in visual acuity preceded a measurable change in the visual field. The pattern of field changes was an increasingly severe, uniform depression. Optic nerve ischaemia induced by compression was probably the most important factor causing visual failure in this case.  (+info)

Factors associated with the poor final visual outcome after traumatic hyphema. (6/2067)

In order to determine the factors related to the worse final visual outcome following nonperforating traumatic hyphema, the clinical characteristics of 18 patients with visual outcome of 0.1 or worse were compared with those of 166 patients with visual outcome of 0.15 or better. The presence of posterior segment injuries such as macula edema, retinal hemorrhage, epiretinal membrane, and choroidal rupture were significant factors of a poor final visual outcome (P < 0.01). The presence of anterior segment injuries such as corneal blood staining, traumatic mydriasis, iridodialysis, cataract, and lens subluxation had significant predictive factors on a poor final visual outcome and the concurrent posterior segment injuries were more frequent in these patients. Initial visual acuity of 0.1 or worse, glaucoma, vitreous hemorrhage, and eyelid laceration were also significant associations of a poor final visual outcome (P < 0.05). Patients with initially larger hyphema (grade I or more vs microscopic) and older age group (16 years or more vs 15 years or less) tended to have poor final visual acuities. Rebleeding was not associated with significant deterioration in visual prognosis. We conclude that the posterior segment injuries seem to be directly related to a poor visual outcome rather than the occurrence of secondary hemorrhage.  (+info)

The need for cataract surgery: projections based on lens opacity, visual acuity, and personal concern. (7/2067)

AIM: To assess the projected needs for cataract surgery by lens opacity, visual acuity, and patient concern. METHODS: Data were collected as part of the Melbourne Visual Impairment Project, a population based study of age related eye disease in a representative sample of Melbourne residents aged 40 and over. Participants were recruited by a household census and invited to attend a local screening centre. At the study sites, the following data were collected: presenting and best corrected visual acuity, visual fields, intraocular pressure, satisfaction with current vision, personal health history and habits, and a standardised eye examination and photography of the lens and fundus. Lens photographs were graded twice and adjudicated to document lens opacities. Cataract was defined as nuclear greater than or equal to standard 2, 4/16 or greater cortical opacity, or any posterior subcapsular opacities. RESULTS: 3271 (83% response) people living in their own homes were examined. The participants ranged in age from 40 to 98 years and 1511 (46.2%) were men. Previous cataract surgery had been performed in 107 (3.4%) of the participants. The overall prevalence of any type of cataract that had not been surgically corrected was 18%. If the presence of cataract as defined was considered the sole criterion for cataract surgery with no reference to visual acuity, there would be 309 cataract operations per 1000 people aged 40 and over (96 eyes of people who were not satisfied with their vision, 210 eyes of people who were satisfied with their vision, and three previous cataract operations). At a visual acuity criterion of less than 6/12 (the vision required to legally drive a car), 48 cataract operations per 1000 would occur and people would be twice as likely to report dissatisfaction with their vision. CONCLUSIONS: Estimates of the need for cataract surgery vary dramatically by level of lens opacity, visual acuity, and patient concern. These data should be useful for the planning of health services.  (+info)

Measuring the effectiveness of cataract surgery: the reliability and validity of a visual function outcomes instrument. (8/2067)

AIMS: To assess test-retest reliability and validity of the "TyPE" patient self assessed visual function questionnaire, as part of a study in two hospitals measuring the effectiveness of cataract surgery. The American TyPE questionnaire had minor adaptations made for use in Britain. METHODS: Test-retest reliability was assessed on 63 out of 378 adult cataract surgery patients in the study, using Spearman correlation coefficients and kappa coefficients of agreement. "Construct" validity was evaluated by comparing the association between changes in visual function questionnaire scores after surgery, with patients' perception of change in visual function obtained by independent interview of 24 patients. RESULTS: The TyPE questionnaire items showed very good test-retest reliability. Average Spearman and kappa coefficients for 39 patients from hospital 1 were 0.93 and 0.84 respectively. Spearman and kappa coefficients of 0.9 and 0.81 were obtained for those nine patients in hospital 2 where both the test and retest questionnaires were filled in by the same people. However, for the 15 patients from hospital 2, where the questionnaire was filled in by different people in the retest, reliability was less good: the Spearman coefficients were still high, average 0.72, but the kappa coefficients were poor, 0.27. Good construct validity was exhibited, with a correlation of 0.79 between change in distance vision score from the questionnaires and the independent interview. CONCLUSIONS: The adapted TyPE questionnaire is both very reliable and has good construct validity. The kappa coefficient should be used wherever possible to evaluate reliability. The test-retest reliability and validity and practicability of other visual function questionnaires have not been assessed adequately, and further development should be carried out of all such questionnaires, so that they may be introduced into routine clinical care.  (+info)

A comprehensive eye examination includes visual acuity, slitlamp exam, pupil exam, intraocular pressure, gonioscope lens and 90D lens with slitlamp exam fundus. A number of eye diseases are irreversible at on early stage. Both glaucoma and diabetic retinopathy(DR)are frequently asymptomatic until significant, often-irreversible, damage to the vision has already occurred. It has been estimated that only 10% of persons in India with glaucoma are diagnosed, and the Handan Eye Survey reports that only 10% of persons with diabetes in rural areas of China have received diabetic eye care. In order to deliver effective care for DR and glaucoma in areas with limited resources, education of patients and interventions to promote compliance among patients will both be needed ...
The purpose of this study was to examine the association between reported visual impairment and mortality among a nationally representative sample of American adults. The studys findings show that severe visual impairment and less severe VI, to a lesser extent, are associated with increased risk of all-cause and cardiovascular-related deaths in American women; no link was found for men. These findings, though not fully understood, are similar to other previous studies on cardiovascular disease. For more information regarding the significance of the link between visual impairment and halacha, please see the explanation of Lee et als Visual Impairment and Unintentional Injury Mortality: The National Health Interview Survey 1986-1994.. ...
Your eyes are an important part of your health. There are many things you can do to keep them healthy and make sure you are seeing your best. Follow these simple steps for maintaining healthy eyes well into your golden years.. Have a comprehensive eye examination.. You might think your vision is fine or that your eyes are healthy, but visiting your eye care professional for a comprehensive eye examination is the only way to really be sure. When it comes to common vision problems, some people dont realize they could see better with glasses or contact lenses. In addition, many common eye diseases such as glaucoma, diabetic eye disease and age-related macular degeneration often have no warning signs. An eye examination is the only way to detect these diseases in their early stages.. During a comprehensive eye examination, your eye care professional may also instill drops into your eyes to dilate, or widen, the pupil to allow more light to enter the eye the same way an open door lets more light ...
A reader asks: As a man at middle age, I am concerned about my eyesight. How can I preserve my eyesight and prevent the progression of vision loss, or is it unavoidable? I am now wearing over-the-counter reading glasses. What is it about carrots, or is that an urban myth?. Sure, aging takes its toll on our eyesight. As time rolls on, the surface of the cornea, the clear covering, flattens and lets less light into the eye. The macula, part of the retina, becomes thinner. Free radicals generated by environmental toxins and our normal body functions also cause many changes. Years of poor eating habits also contribute to visual problems as we age. However, the good news is, rarely is it too late to make a difference. The right changes in lifestyle and diet always can make an improvement. And so it is true also with age-related macular degeneration (AMD), cataracts and glaucoma. These conditions are the most common causes of loss of vision in people over 40. AMD occurs when cells in the macula ...

The question is if those with poor eyesight have increased as a percentage of the population. Our ability to curb poor eyesight with glasses has prevented this genetic code from acting as a Darwinian filter. Logic would indicate that those with poor eyesight (including me) would die off faster and, as a result, produce fewer young in a primitive world. But, given todays circumstances, I wonder if we have seen an ever-increasing number of people with bad eyesight. Could we conclude that our dependence on corrective lenses is, in fact, reducing our ability to see naturally?

In simpler terms, it is a field that connects opthalmology and neurology. ...

Whether it be reading, writing, smart board work, or using a computer; a childs eyes are constantly in use in the classroom and at play.

When you think about improving your eyesight, natural therapies are not usually the first thing that occurs to you. Most people make an appointment with their eye doctor, and resign themselves to the fact that they will be buying new glasses, contact lenses, or maybe even the dreaded bifocals. Your eyes, like any other part of your body, can be strengthened and protected by exercise. Your ophthalmologist probably doesnt advocate this, but since about 1910, a small group of physicians and eye care professionals have been researching and advocating natural vision correction through a system of eye exercises. Dr. William H Bates was one of the leading crusaders for eyesight improvement by natural methods. He was one of the original physicians who believed there was more to vision than the actual physical act of seeing. He believed that vision was a mind/body process that interpreted visual information. Unfortunately, for Dr. Bates, he was about seventy years ahead of his time. In his era of ...

In a 2012 survey, almost 70% of people around the world said theyd rather lose a limb or give up 10 years of their life rather than lose their eyesight. This question, among others, was asked to over 11,000 people across 11 countries in a survey performed by eye care company Bausch + Lomb. Of course, the thought of losing a limb or eyesight is almost unbearable to those who dont currently face those daily struggles. Having to choose might not come easy but heres the thinking.. If someone loses a limb, there are medical treatments - prosthetics - that can help such a fellow becomes mobile again. The fellow might unlikely be able to move quite the same, but could, at a minimum, get some function back. But theres no prosthetic eye that gives you your vision back.. So if our vision is so important to us, why do we ignore our eye health? In the 2012 survey, only 21% had an eye exam in the previous 5 years. In the survey, less than one third said they do what they should to preserve their eye ...

Despite nine months of growth in utero, babies are not born with fully developed eyes and vision - just like they cant walk or talk yet. Over the first few months of life, their visual systems continue to progress, stimulated by their surroundings.. Babies will develop the ability to track objects, focus their eyes, and move them like a team. Their visual acuity will improve and they will gradually be able to see more colors. They will also form the neural connections that will allow them to process what they see, to understand and interact with the world around them. Healthy eyes and good vision are necessary for proper and timely progress; ocular or visual problems can lead to developmental delays. So how do you know if your infant is developing normally? What can you do to ensure your babys eye health and vision are on track? While infant eye problems are not common here are some steps you can take to ensure your childs eyes are healthy. ...

We believe in healthy happy communities. One of the ways we work towards this is by conducting regular eye checks, particularly for school children. These can identify vision problems that may also be an obstacle to learning. Many children do not receive any professional eye care until they become adults. By then some may have suffered loss of development due to poor eyesight or eye disease.. Our vision screening program is a free community service and a valuable tool for parents and educators. It helps ensure that any eye health concerns are addressed quickly. The screenings are quick and fun for children. Parents receive a vision screening report of their child including a basic assessment and any recommendation for a further comprehensive eye examination if required..

School is back in full swing which is easy to tell with the traffic and supply lists at nearly every store in the country. New shoes, clothes, bags and schedules are the order of the day.. Did your children start school with good eyesight? Most of our learning approximately 80+% occurs through vision. Often parents overlook this important part of the learning cycle until the school gets around to screening the students or their child starts complaining that they are having difficulty seeing or having headaches.. Life gets busy and if there isnt an obvious problem of complaint things get put off, but vision and eye health should not be one of those. Schools are only required to screen certain grades and this is surprisingly often done at the end of the school year. As a parent you can not rely on those screening to determine if your children should have a comprehensive eye examination.. Good habits develop early when an emphasis is on teaching reading and foundational arithmetic. This time is ...

APEDS was a population based study representative of the population of the Indian state of Andhra Pradesh with a good participation rate.. We have previously reported data on moderate visual impairment from the urban area of APEDS using two definitions of moderate visual impairment.7 In the previous report, the prevalence of moderate visual impairment in the urban area was estimated at 7.2% with definition one (presenting distance visual acuity ,6/12-6/60 or equivalent visual field loss), and 4.8% with the other more conservative definition two (presenting distance visual acuity ,6/18-6/60 or equivalent visual field loss).7 These estimates were adjusted for the population distribution of India available from the year 1991 census.7 For this report, we have adjusted the estimates for the most recent data for the estimated population distribution of India in the year 2000.3,13 On adjusting the urban area estimates for the estimated population distribution of India in the year 2000, the prevalence ...

It is prudent to contact an ophthalmologist at some health care center at the earliest if you suspect poor vision in your child. He or she will confirm poor vision and then look for the cause of the same. A timely treatment is very crucial in saving the sight and sometimes the life of the child.. There are many special tests available which help the doctor in determining the visual acuity of children in all age groups. The ophthalmologist will decide which tests to use and will get an idea of the visual loss and the chances of getting good vision after treatment.. Take immediate care as soon as poor vision is detected in a child -. If the poor vision in child is not treated early enough, the eye may not develop properly and develop a condition called amblyopia (lazy eye). Therefore, if the eye is treated at a later stage, the eye may not get good vision. It is very important to treat the cause of poor vision, e.g., refractive error, cataract, glaucoma, diseases of cornea etc. as early as ...

Its extremely common to have deteriorating eyesight as you age. Vision problems can be present at birth or not show up until later in life. Vision problems can become apparent at any point during an individuals life, and the point of onset and severity varies greatly from person to person.. Vision problems can occur for no apparent reason, and are often hereditary. Various eye diseases can cause impaired vision, such as glaucoma, cataracts, macular degeneration, and diabetes. Vision problems can also occur as a result of injury or as a natural part of the aging process.. Diseases of the eye tend to become more common with age. Glaucoma, macular degeneration, and cataracts are all eye conditions that are far more prevalent in the older population than in younger generations. Macular degeneration that occurs with aging is one of the leading causes of total blindness. Glaucoma is another leading cause of vision problems, affecting one in ten individuals over the age of eighty. Over the age of 74, ...
Why are our eyes called the windows to our souls? Why do we speak of the way that we see the world? Why do we say, I see, in order to communicate that we understand? What is the understanding? What is the relationship between our vision, our eyesight, and our way of Being? Eyesight is not just a physical process involving acuity. It is a multi-dimensional function affecting and affected by our emotional and mental state of Being, and linked to our personalities. That is, each type of vision impairment correlates with specific personality types. All nearsighted people have something in common in their personalities, and all farsighted people share a particular character trait, and all those with astigmatism are working with a similar issue in their lives. All kinds of impaired vision represent stressed ways that a person interacts with their environment. Some say that stress is responsible for all emotional and physical imbalances, and stress reflects how an individual interacts with his or ...
In addition to being qualified to perform complex surgery, a pediatric ophthalmologist can manage childrens eye problems using glasses and medications. With early diagnosis, good vision can develop and be maintained.
The preventive effects of therapy and the fact that patients with PDR or macular edema may be asymptomatic provide strong support for a screening program to detect diabetic retinopathy. Because retinopathy is estimated to take at least 5 years to develop after the onset of hyperglycemia, patients with type 1 diabetes should have an initial dilated and comprehensive eye examination within 5 years after the diabetes diagnosis (48). Patients with type 2 diabetes who may have had years of undiagnosed diabetes and have a significant risk of prevalent diabetic retinopathy at the time of diagnosis should have an initial dilated and comprehensive eye examination shortly after diagnosis. Examinations should be performed by an ophthalmologist or optometrist who is knowledgeable and experienced in diagnosing diabetic retinopathy. Subsequent examinations for type 1 and type 2 diabetic patients are generally repeated annually. Exams every 2 years may be cost-effective after one or more normal eye exams, and ...

The only way to prevent glaucoma progressing, is to have your eyes examined regularly. A comprehensive eye examination with one of our highly-trained optometrists allows us to thoroughly screen for glaucoma. As there are typically no early warning signs or symptoms of glaucoma, it is very important to have a regular eye examination even if you are not having any problems. If you can see well, or you dont wear glasses, a regular eye examination will help detect glaucoma early enough to prevent any visual field loss.. Our optometrist will perform a simple painless procedure during the eye examination to measure the eye pressure. Most people do not like to have the puff test, as they find it uncomfortable. We have invested in a newer, quicker and more accurate way of measuring your eye pressure. We will examine your optic nerve and carry out a retinal scan, for better monitoring of any changes, as well as doing a field of vision test. The visual field test we carry out, is one of the most ...
About half of people with MS experience at some point in their life a condition called acute optic neuritis, in which the nerve carrying vision from the eye to the brain gets inflamed, said study author Raj Kapoor, MD, with the National Hospital for Neurology and Neurosurgery in London, England. The condition can cause sudden total or partial blindness, foggy or blackened vision and pain. Even though eyesight can recover eventually, each attack still damages the nerve and the eye.. For the study, the researchers randomly selected 86 people with acute optic neuritis within two weeks of having symptoms to receive either the epilepsy drug phenytoin or a placebo for three months. The researchers then used medical imaging to measure the thickness of the retina, the light sensitive nerve layer at the back of the eye at the beginning of the study and then six months later. Each patients eyesight (including sharpness and color perception) was also tested.. The study found on average that the group ...

Vision screening by a school nurse, pediatrician or other qualified health provider is the best way to ensure healthy vision in children. Eyes should be examined during regular pediatric appointments and vision testing should be conducted around age three. If there are issues, theyll be referred to a pediatric ophthalmologist for a comprehensive eye exam.. Parents should be aware of signs that may indicate their child has vision problems, including ...
The findings are published in the April 21 advance online issue of Cell Research.. Retinitis pigmentosa (RP) is a group of inherited vision disorders caused by numerous mutations in more than 60 genes. The mutations affect the eyes photoreceptors, specialized cells in the retina that sense and convert light images into electrical signals sent to the brain. There are two types: rod cells that function for night vision and peripheral vision, and cone cells that provide central vision (visual acuity) and discern color. The human retina typically contains 120 million rod cells and 6 million cone cells.. In RP, which affects approximately 100,000 Americans and 1 in 4,000 persons worldwide, rod-specific genetic mutations cause rod photoreceptor cells to dysfunction and degenerate over time. Initial symptoms are loss of peripheral and night vision, followed by diminished visual acuity and color perception as cone cells also begin to fail and die. There is no treatment for RP. The eventual result may ...

Foods for Better Eyesight and In Home Senior Care. As we age, there are many reasons to start eating right and to find ways to fuel our bodies in a healthy way. We have learned that food plays an important role in how we feel and perform through the day. There are good foods and bad, and while its important to avoid eating poorly all of the time; moderation is key to healthy and happy living. Some foods are particularly good for certain parts of the body. We may take for granted our gift of sight, and as we age, and with certain medications, vision may become poor. Food can play an important role in improving eyesight. Oily fish such as salmon and tuna are not only easy to prepare, but are also delicious to serve as main dishes. Oranges and other juices are great for providing Vitamins and can be incorporated in cooking and served with meals.

Many optometrists regard school eye tests as a notoriously poor indicator of visual problems. Standards vary widely, and in the worst cases a dodgy chart is hung up at the end of a corridor and the children become familiar with the letters while filing past. Parents get a letter saying their childs eyesight is normal, but such reassurances can be dangerous. The test may not pick up eye disease or binocular vision problems, where the two eyes dont work well together. However, the City University Vision Screener for Schools, designed by Dr David Thomson, senior lecturer in the universitys Department of Optometry, could change all that. It is a computer programme devised to pick up visual defects that might affect the education or development of the child, such as squints (which need to be picked up as early as possible to stand any chance of successful treatment), refractive errors like short-sightedness or long-sightedness (which might result in blurred vision or headaches) and colour vision ...
Family physicians have an essential role in assessing, identifying, treating, and preventing or delaying vision loss in the aging population. Approximately one in 28 U.S. adults older than 40 years is visually impaired. Vision loss is associated with depression, social isolation, falls, and medication errors, and it can cause disturbing hallucinations. Adults older than 65 years should be screened for vision problems every one to two years, with attention to specific disorders, such as diabetic retinopathy, refractive error, cataracts, glaucoma, and age-related macular degeneration. Vision-related adverse effects of commonly used medications, such as amiodarone or phosphodiesterase inhibitors, should be considered when evaluating vision problems. Prompt recognition and management of sudden vision loss can be vision saving, as can treatment of diabetic retinopathy, refractive error, cataracts, glaucoma, and age-related macular degeneration. Aggressive medical management of diabetes, hypertension, and
