Clinical profile of multiple sclerosis in Bengal. (1/354)

Forty five patients of multiple sclerosis diagnosed on the basis of Poser's criteria from West Bengal were studied. The male-female ratio was 1:1.5, mean age of onset 31.83 years in male and 29.11 years in females. The maximum cases were between the 3rd and 4th decade. Definite MS comprised of 60%, while remaining 40% were probable. Visual impairment (53.33%), weakness of limbs (31.11%) and sensory paraesthesia (20%) were the common presenting symptoms whereas pyramidal tract involvement (93.33%) with absent abdominal reflexes (90%) and optic pallor (64.44%) were common signs. Posterior column and spinothalamic sensations were involved in 55% and 51% of cases respectively. Inter-nuclear ophthalmoplegia was present in 6.66% of cases. Pattern of involvement commonly showed three or more sites of lesion. Optico-spinal affection was present in 22.2% of cases. Relapsing and remitting course was found in 48. 91%, relapsing and progressive course in 33.33% and chronic progressive in 17.8%. MRI of brain showed positive results in 16 out of 23 cases. CSF study showed increased positivity in estimation of immunoglobulin level than oligoclonal band. Findings revalidate the disease pattern as being similar to that in other parts of India as well as Asia.  (+info)

Chronic cortical visual impairment in children: aetiology, prognosis, and associated neurological deficits. (2/354)

BACKGROUND/AIMS: To evaluate prevalence, aetiology, prognosis, and associated neurological and ophthalmological problems in children with cortical visual impairment (CVI). METHODS: The records of 7200 outpatients seen in the paediatric ophthalmology practice over the past 15 years were reviewed in order to compile data concerning CVI. In addition, the authors devised and applied a system for grading visual recovery in order to assess prognosis. RESULTS: CVI occurred in 2.4% of all patients examined. The four most common causes of CVI were perinatal hypoxia (22%), cerebral vascular accident (14%), meningitis (12%), and acquired hypoxia (10%). Most children with CVI had associated neurological abnormalities. The most common were seizures (53%), cerebral palsy (26%) hemiparesis (12%), and hypotonia (5%). Associated ophthalmological problems were esotropia (19%), exotropia (18%), optic nerve atrophy (16%), ocular motor apraxia (15%), nystagmus (11%), and retinal disease (3%). On average, CVI patients improved by two levels as measured by the authors' scale. CONCLUSION: The majority of children with CVI showed at least some recovery. In this group of children, CVI is often accompanied by additional ophthalmological problems and is nearly always associated with other, serious neurological abnormalities.  (+info)

Prevalence of self-rated visual impairment among adults with diabetes. (3/354)

OBJECTIVES: This study estimated the prevalence of self-rated visual impairment among US adults with diabetes and identified correlates of such impairment. METHODS: Self-reported data from the 1995 Behavioral Risk Factor Surveillance System survey of adults 18 years and older with diabetes were analyzed. Correlates of visual impairment were examined by multiple logistic regression analysis. RESULTS: The prevalence of self-rated visual impairment was 24.8% (95% confidence interval [CI] = 22.3%, 27.3%). Among insulin users, multivariable-adjusted odds ratios were 4.9 (95% CI = 2.6, 9.2) for those who had not completed high school and 1.8 (95% CI = 1.0, 2.8) for those who had completed high school compared with those with higher levels of education. Comparable estimates of odds ratios for nonusers of insulin were 2.2 (95% CI = 1.4, 3.4) and 1.3 (95% CI = 0.9, 2.0), respectively. Among nonusers, the adjusted odds for minority adults were 2.4 (95% CI = 1.0, 3.7) times the odds for non-Hispanic Whites. CONCLUSIONS: By these data, 1.6 million US adults with diabetes reported having some degree of visual impairment. Future research on the specific causes of visual impairment may help in estimating the avoidable public health burden.  (+info)

Cancer-associated retinopathy during treatment for small-cell lung carcinoma. (4/354)

A 70-year-old woman with small-cell lung carcinoma (c-T4N2M0) was treated by six courses of combination chemotherapy (carboplatin and etoposide). After two weeks, she complained of a sense of darkness and night blindness. A Western blot analysis showed that the patient's serum bound with the recombinant 23-kDa retinal cancer-associated retinopathy (CAR) antigen at 1:1,000 dilution. Her visual acuity became so poor that she could only recognise a hand motion at 50 cm despite treatment with corticosteroids and combination chemotherapy. The patient was diagnosed as having a rare type of CAR because CAR is usually found before the diagnosis of primary cancer.  (+info)

Utilisation of eyecare services in an urban population in southern India: the Andhra Pradesh eye disease study. (5/354)

AIM: To assess utilisation of eyecare services by people with visual impairment <6/18 or equivalent visual field loss in the better eye in the urban population of Hyderabad in southern India. METHODS: 2522 subjects of all ages, representative of the population of Hyderabad city, underwent a detailed interview and dilated examination as part of the population based Andhra Pradesh eye disease study. Subjects more than 15 years of age were interviewed regarding the use of eyecare services. RESULTS: Of 250 subjects with presenting distance visual acuity <6/18 or equivalent visual field loss in the better eye, information on utilisation of eyecare services was available for 229 (91.6%). Of these 229 subjects, 44 (19%) had visual acuity <6/60 or equivalent visual field loss in the better eye, and 202 (88.2%) had noticed decrease in vision over the past 5 years. Multivariate analysis showed that this decrease in vision was noticed significantly less by subjects with refractive error as the cause of visual impairment (odds ratio 0.34, 95% confidence interval 0.12-0.93). Of the 229 subjects who were visually impaired, 108 (59%) did not seek treatment. Multivariate analysis revealed that the odds for seeking treatment were significantly lower for Hindus than Muslims (odds ratio 0.53, 95% confidence interval 0.28-0.98). The reasons for not seeking treatment could be classified as personal (49.5%), economic (30.8%), and social (19.6%). CONCLUSION: A large proportion of subjects with visual impairment in this urban population in India did not seek treatment even after noticing decrease in vision. Projecting these data to the 155 million urban population >15 years of age in India, there may be 4.9 million (95% confidence interval 4.3-5.5 million) people in urban India who are not seeking treatment for their visual impairment even after noticing decrease in vision. These data suggest that efforts have to be made to better understand the reasons for this phenomenon so that optimal utilisation of the available eyecare services in urban India can be planned.  (+info)

Clinical effect of low vision aids. (6/354)

The number of patients with low vision is increasing as life expectancy increases. In addition, the interest and demand for low vision aids are also increasing with improved socioeconomic status and the development of mass media. Therefore, it is imperative to recognize the importance of low vision aids. We reviewed the clinical records of 118 patients who visited our low vision clinic more than twice. According to the data analyzed, optic nerve atrophy, retinal degeneration, diabetic retinopathy and age-related macular degeneration were the most common causes of low vision in these patients. The best corrected visual acuities without low vision aids were less than 0.3, but with the help of low vision aids, vision improved to more than 0.4 in 87% of the patients for near vision, and 56% for distant vision. The patients had complained that they could not read books, see a blackboard, recognize a person at a distance, and had other problems because of low vision. However, with the use of low vision aids their satisfaction with their vision rose to 70%. Hand magnifiers, high-powered spectacle lenses, and stand magnifiers were the low vision aids commonly used by people for near vision, while the Galilean telescope and Keplerian telescope were the most popular devices used for distant vision. In conclusion, low vision aids are very helpful devices to patients with low vision.  (+info)

Chronic, traumatic intraconal hematic cyst of the orbit removed through the fronto-orbital approach--case report. (7/354)

A 22-year-old male presented with a chronic encapsulated intraorbital hematoma 3 months after blunt trauma to his left eyeball. Ophthalmological examination found the best corrected visual acuity was 4/20 in the left eye, and 20/20 in the right eye. The orbit exhibited exophthalmus and inability of the eye to move above the horizontal level. Orbital magnetic resonance imaging showed a fairly well-demarcated area in the medial aspect of the orbit appearing as hyperintense on T1-weighted images and isoto hyperintense on T2-weighted images. This area was believed to be hemorrhage. No other abnormalities were found. The diagnosis was hematic cyst. The cyst was approached through a left fronto-orbital route and its location identified within the periorbita and orbital fat. The cyst was removed partially. Histological examination demonstrated cystic accumulation of blood and breakdown products in a non-epithelium-lined fibrous capsule, compatible with hematic cyst. The presence of hemosiderin in the cyst wall suggested that the cyst was a chronically enlarging lesion. Hematic cysts of the orbit usually present as subperiosteal mass months to years after trauma. Surgical removal of the cyst wall rather than needle aspiration is recommended to prevent recurrence.  (+info)

Elicited sequential presentation for low vision reading. (8/354)

This paper reports on a variant of the rapid serial visual presentation (RSVP) technique for low vision reading called elicited sequential presentation (ESP). In both techniques, words are presented sequentially at a constant screen location, but with ESP, the reader elicits presentation of each new word by means of a button press, rather than (as with RSVP) being presented with it automatically at fixed intervals. An experiment comparing reading speeds using, ESP, RSVP and a conventional closed-circuit television (CCTV) reading aid showed that for 15 slow readers who were customary CCTV users with low vision, ESP is superior to RSVP and yields reading speeds averaging 47% faster than RSVP--about the same as CCTV reading speed. The log of the ratio of ESP to RSVP reading speeds was significantly negatively correlated with the log of RSVP reading speed, showing that slower readers benefit more than faster readers; regression predicted no benefit for readers who read with RSVP at 133 wpm or greater. Finally, word length and word presentation duration chosen by subjects reading with ESP were significantly correlated, suggesting that part of the benefit of ESP is due to reader's ability to allocate time based on word length and difficulty.  (+info)

Barriers to Low Vision Rehabilitation: A Qualitative Approach, Online, Structured Abstract: Introduction: This study sought to describe and better understand barriers to accessing low vision rehabilitation services. Methods: A qualitative description research paradigm was employed. Focus group participants were recruited through their involvement in the Montreal Barriers Study in Montreal, Canada. Six focus groups (n = 21 participants) were conducted to assess perspectives (both positive and negative) about accessing low vision rehabilitation services, and in particular the barriers to accessing these services. Interview transcripts were prepared and analyzed using content analysis. Results: Analyses revealed barriers inherent to the person (perceived ability to comfortably engage in activities of daily living and gradual participatory losses); the clinic (inefficiencies in educating clientele about low vision rehabilitation services, and problems and dissatisfaction associated with ophthalmic
Low vision rehabilitation research is a quickly growing area, due in part to the increase in the demand for services geared at older adults with age-related vision loss. Various professions collaborate to provide such rehabilitation services; however, it is currently unclear which profession takes the leading role in advancing the frontiers of low vision rehabilitation research. A recent review article proposed that in Canada, this role is held by physicians. The present study was conducted to replicate these findings under conditions of a systematic review ...
Our team is interested in what can be done to improve the functioning of patients who suffer from glaucoma, a chronic and irreversible eye disease. Patients with vision loss as a result of this disease may feel like they have been given up on, or lost to our medical system when no further interventions can be offered to treat their eye disease. It is our intent to investigate what alternatives we can provide our patients, instead of simply saying, nothing more can be done. We have learned from studies done on other chronic eye diseases, like age related macular degeneration, that low vision rehabilitation can improve visual function.. What exactly is low vision? It can involve a loss of visual acuity, making activities such as reading or writing a challenge; it can involve loss of contrast sensitivity, making shapes and edges hard to discern, like those of a stair edge, or persons face. It could also involve a loss of peripheral, or side vision which is a symptom common to most glaucoma ...

Low Vision What is Low vision? Low vision is a condition characterised by level of vision that is 20/70 or worse and that cannot be fully corrected with medical treatment, surgery, or conventional glasses. Unlike total blindness, most individuals with low vision have some useful sight. But, as vision deteriorates, those affected often find it difficult to accomplish the tasks of everyday life such as reading, recognizing faces, cooking, driving, and differentiating color. In most cases, the low vision makes patient unable to live a normal and independent life.. Children and adults can have low vision at any stage in life. Most people develop low vision as a result of eye conditions and diseases, including congenital eye diseases, macular degeneration, diabetic retinopathy, glaucoma, cataracts, retinitis pigmentosa, and trauma. Some causes of low vision, such as cataracts, are treatable and good vision can be restored. When diagnosed early, other conditions that lead to low vision, such as wet ...
Purpose : One in three vision impaired older adults has subclinical symptoms of depression and/or anxiety and is at risk of full blown psychiatric disorders. This puts a burden on quality of life of patients and on societal resources. Recently our stepped-care program proved to be effective in preventing development of disorders (relative risk: 0.63), however, evidence of cost-effectiveness is not yet available. We performed an economic evaluation alongside a multicenter randomized clinical trial to investigate the cost-effectiveness from a societal perspective of this new intervention to prevent depressive and/or anxiety disorders. Methods : Vision impaired adults (,50 years) having subclinical symptoms of depression and/or anxiety (mean age 74, 70% women, 46% macular degeneration) from 17 Dutch and Belgian low vision rehabilitation centers were randomized to stepped-care (n=131) or usual care (n=134). If symptoms persisted as assessed every three months, patients moved to the next more ...
Low Vision Rehabilitation of Retinitis Pigmentosa, Online, Retinitis pigmentosa is a rod-cone dystrophy, commonly genetic in nature. Approximately 60–80% of those with retinitis pigmentosa inherit it by an autosomal recessive transmission (Brilliant, 1999). There have been some reported cases with no known family history.
These conditions can occur at any age but are more common in older people. Normal aging of the eye does not lead to low vision. It is very important to have regular eye exams by your ophthalmologist so that he/she can diagnose eye diseases, treat those conditions that can be helped, and start the process of vision rehabilitation.. LOW VISION TREATMENT. Vision rehabilitation can help people with low vision compensate for their vision loss. Those with low vision can learn new strategies to complete daily activities. By mastering new techniques and devices, one can regain confidence and live independently in spite of vision loss. This period of adjustment can be challenging for some. It requires patience, practice, motivation and the support of your doctor, family and friends. The amount of rehabilitation needed depends on your vision loss and what you want to be able to do.. LOW VISION AIDS. Many devices can help people with low vision make the most of their remaining vision and can enhance the ...
The National Eye Institute has designated February as Low Vision Awareness Month, a time to raise awareness about visual impairment and rehabilitation for those living with the condition. An estimated 3 million Americans age 40 and older are living with low vision, which can greatly impact their functionality, productivity and general enjoyment of life.. What is Low Vision?. Low vision is defined as having 20/70 vision or poorer in the better eye with maximum correction. The diagnosis often means that a person must live with blurred vision, tunnel vision or blind spots.. Following are the definitions of visual acuity, according to the World Health Organization. These ratings are for vision in the better eye with the best possible prescription corrective lens:. 20/30 to 20/60: Mild vision loss, but near-normal vision. 20/70 to 20/160: Moderate low vision. 20/200 to 20/400: Severe low vision. 20/500 to 20/1,000: Profound visual impairment. Less than 20/1,000: Near-total blindness. No light ...

If low vision problems are recognized early, treatment can begin in an effort to prevent as much deterioration as possible and improve quality of vision and life. An examination for low vision is not the same as a typical eye exam and may involve a test for refraction (to evaluate vision and determine if corrective lenses may be helpful), visual field (which assesses peripheral vision), and ocular motility (to identify how well the eyes move). What type of eye doctor should you consult? Ophthalmologists are medical or osteopathic doctors who specialize in the eye. They perform eye exams, diagnose and treat disease, prescribe medications and eyeglasses, and perform surgery. Optometrists examine the eyes for vision and health problems, diagnose and treat eye problems and diseases, and prescribe ophthalmic medications. Some optometrists provide low vision care. If you are diagnosed with low vision, you will want to be treated by a low vision specialist. Treatment for low vision can include several ...

A recent survey found more than half of low vision patients are unwilling to use assistive devices, even when they improve their visual performance. Researchers in India interviewed 413 low vision patients from their tertiary eye hospital to uncover the reasons 235 of them shy away from assistive technology. They found cost and convenience werent necessary to blame. In fact, the biggest factor for patients older than age 40 was social stigma (cited by 41.3% of the patients). Those between the ages of 41 and 60 were most likely to avoid these tools due to a fear of losing their job (26.6% of patients). Of all patients younger than 60, 25% felt they didnt need them, despite the fact that the researcher found 53% of those who felt there were not candidates actually had severe visual impairment. Those older than 60 seem to have a harder time accepting their failing vision, as 16.5% were in denial about the magnitude of their condition, the researchers wrote. However, this statistic was somewhat ...
What is low vision? Low vision is a loss of eyesight that cannot be sufficiently improved with conventional glasses, contact lenses, or medical and surgical interventions. Low vision interferes with everyday tasks. A person with low vision may find very hard to accomplish activities such as reading, writing, shopping, watching television, driving a car, or recognizing faces.
The Teacher for Students who are Blind or have Low Vision also keeps in contact with the parents either directly or through the teacher of service in the building in which the student attends. Support to the parents is given in many ways. Communication may be through names and numbers of optometrists/ophthalmologists or workshops available for students/parents in the area. Blind/Low Vision services offered through the Outreach program at the Indiana School for the Blind and Visually Impaired can also be facilitated by the TSBLV ...
Visual aids enable millions of people who suffer from low vision to be able to function and live relatively normal lives, by maximizing their remaining eyesight. An optometrist can do a low vision eye exam and provide specialized glasses or tints to optimize vision, or recommend quality magnifiers with appropriate magnification and working distance. Full spectrum lighting or magnifiers with an attached light source are often used to aid individuals with low vision. You can also get special lens tints, which are used to enhance contrast and reduce glare, with special coatings for specific conditions. Other low vision aids act as guides to help the person focus on non-visual cues, such as sound or feel. Many people unfortunately try a trial and error or dollar store readers or magnifiers when it comes to vision aids which can lead to frustration. In fact, there is a systematic approach. to finding the right visual aid, which is a matter of consulting with a professional to determine what works ...

Low vision rehabilitation is like physical therapy after loss of a limb. The end result is maintenance of independence and a sense of self-worth. This rebuilding and reinforcement of the visual foundation is mainly accomplished through identification of goals, introduction to low vision devices, and training. After evaluation by a low vision specialist, specially trained therapists teach daily activities such as safe cooking strategies, proper lighting, labeling techniques, and use of adaptive equipment. Such equipment includes optical devices like prescription magnification glasses, electronic magnifiers, telescopes, and computer magnification software. Non-optical approaches are also introduced, such as large print books, talking books, and scanners that read printed material aloud. Low vision rehabilitation is an important part of the continuum of care following diagnosis of AMD. Such training will help you maintain your quality of life and independence by finding new ways to function and ...

Some people with significantly reduced acuity may benefit from training conducted by individuals trained in the provision of technical aids. Rehabilitation professionals, some of whom are connected to an agency for the blind, can provide advice on lighting and contrast to maximize remaining vision. These professionals also have access to non-visual aids, and can instruct patients in their uses. Visually impaired patients may benefit from high-tech aids such as OCR scanners that can, in conjunction with text-to-speech software, read the contents of books and documents aloud via computer. Vendors also build closed-circuit televisions that electronically magnify paper, and even change its contrast and color, for visually impaired users. The vast majority of patients with low vision can be helped to function at a higher level with the use of low vision devices. Low vision specialists recommend appropriate low vision devices and counsel patients on how better to deal with their reduced vision in ...

The patient with impaired vision represents a challenge to eye-care professionals. Whether temporary or permanent, low vision is the consequence of an eye disorder, and ophthalmologists and optometrists have a responsibility to manage it. If the outcome of optimal medical and surgical intervention is diminished functional vision, the patient needs vision rehabilitation (see also Chapter 25). No person with low vision should have to search far and wide for low-vision care. Some level of care should be integrated into every ophthalmic practice, either on-site or by referral to a low-vision center. ...

Using outcomes from a recently completed clinical trial, the Low Vision Depression Prevention Trial in Age-Related Macular Degeneration (VITAL) study, 188 senior adults with low vision from age-related macular degeneration were evaluated.

Aim: To conduct a Rapid Assessment of Cataract Surgical Services estimate the prevalence and causes of blindness and visual impairment in the population aged ≥40 years in Limbe Urban Area, Cameroon. Methods: Clusters of 50 people aged ≥40 years were sampled with probability proportionate to size. Compact segment sampling was used to select households within clusters.

The prevalence of bilateral blindness was 1.1% (95% CI: 0.7-1.5%), 0.3% (0.1 -0.6%) for severe visual impairment and 3.0% (2.0 - 4.0%) for visual impairment. Posterior segment disease was the leading cause of blindness (29%), followed by cataract (21%) and optic atrophy (21%). Cataract was the most common cause of severe visual impairment (43%) and visual impairment (48%). Most cases of blindness (50%), severe visual impairment (57%) and ...

For the fourth year in a row, the UAB Department of Occupational Therapy handed out one of their most prized possessions - the infamous Golden Toilet Award.. First year M.S. in Occupational Therapy students (pictured L/R) EJ Johnston, Elaine Kurtz, Emily Hug and Mallory Jordan joined the distinguished list of past winners and signed the lid of the prestigious award. They beat out 12 other teams, consisting of four MSOT students each, to take first place.. The annual competition is part of the OT 677: Foundations in Low Vision Rehabilitation course. The challenge is for students to design and build restroom signs - with a catch. The signs must be reliably read by people with 20/200 visual acuity (the visual acuity of someone with cataracts) at a distance of 10 feet. In order to prepare, the students wore special simulation glasses so they would understand the difficulties people with cataracts face every day trying to read signs.. This is our fifth year to host this competition and every year we ...
