We reviewed the consecutive series of 228 legally blind patients at an urban hospital during 1994. The series included 175 patients (77%) aged 60 years or over and 10 patients (4%) under 40 years of age. There were 105 males (46%) and 123 females (54%). Degenerative myopia was the most common cause involving 53 patients (23%). There were 49 patients (22%) with diabetic retinopathy and 43 (19%) with glaucoma. Visual impairment in patients under 50 years of age was mainly due to various heredodegenerative conditions.
