Survey of major blinding conditions in Qatar

Qatar is one of the rapidly developing Gulf States. Its life style is rapidly changing from a seminomadic to a more settled urban one. This is the first study of the causes of economic blindness (6/60) in Qatar. It embraces 3,072 patients (70% males and 30% females). The most common causes in those under 40 years of age were trachoma, infectious diseases, retinal diseases, trauma and congenital malformations. After 40 years, cataract and glucoma occupy the second and third commonest causes after trachoma. Thus, a proper antitrachoma campaign will cut down the incidence of blidness by 50%. Control of individual behavior and antenatal caution in prescribing medicines can reduce the risk of trauma and congenital malformations. Cataract is not preventable, but early detection of glaucoma delays the damage of ocular tissues. This is the same with systemic disease.
