PURPOSE
To determine the etiology, clinical diagnosis prognosis and to identify the major treatable and preventable causes of visual disability among attendees at the Al -Noor institute for the visually impaired ,Bahrain.
METHODS
Using the standardized methodology of the world Health Organization, a detailed study was conducted of 124 visually disabled subjects , mainly children . At the Al -Noor institute for the visually impaired. The patients were examined clinically during 1994 and 1995. There were 70 Bahrainis and 54non - Bahrainis: 81 were male and 43 female.
RESULTS
The main causes of visual disability were due to hereditary diseases (42%). The main cause was retinal dystrophy, while glaucoma cataract, intrauterine infections and retinopathy of prematurity were the other main causes. Data analysis revealed that 46.8% had parents who were closely related. Moreover, the consanguinity was 63.2% in those subjects with a positive family history of visual disability among closely related family members. On the other hand, subjects who had a negative or unknown family history revealed consanguinity among parents in 32.9% of cases.
CONCLUSION
The main cause of blindness is hereditary disease Consanguinity represents an important factor in visual disability among children.

VISUAL DIASABILITY SURVEY IN BAHRAIN
Ebtisam Al Alawi MD, Ahmed Ahmed, Bahaa Fatiha, Salmaniya Medical Complex, Manama , Bahrain.
OBJECTIVES
To establish the baseline profile of visual disability among randomly selected samples of Bahraini population . To identify the causes of visual disabilities.
METHODS
Cross sectional survey of a randomly selected sample of Bahraini population. Using WHO standard methodology to record the findings . Eye examination included an initial screening of the subjects, then full ophthalmological examination for cases with visual impairment or visual disability .
RESULTS
A representative sample was selected and 2426 was included in the study . The survey revealed that 3/60 was 4% and found that refractive errors constitute % of the cases . Cataract 8.7% glaucoma 4.1% . macular degeneration 2.6% and diabetic retinopathy 2.0% . On the otherhand, bilateral blindness (Visual acuity less than 3/60 was 1.9% Cataract and glaucoma constitute the major causes of blindness (21.3% and 9.6% respectively , followed by control opacity 6.4% refractive errors 4.3% and diabetic retinopathy was 2.0% .
CONCLUSION
The overall visual disability was 12.7% .The bilateral blindness was 2.0% and bilateral low vision was 4.0% .The major causes of visual disability was identified. Refractive errors constitute the main cause of impairment and cataract the major cause of disability.
A total of 228-procedure ware needed for action. Recommendation to identify and treat visual disabilities will be discussed. This study was done in collaboration with IMPACT.
