OBJECTIVE
To investigate the prevalence and risk factors of diabetic retinopathy.


METHODS
29,938 subjects aged 30 years or older were screened for diabetic retinopathy in Capital Steel Company.


RESULTS
Among the 955 subjects (3.19%) proved to have diabetes mellitus, 534 subjects underwent ophthalmoscopic and fluorescein angiographic examinations. Diabetic retinopathy was present in 90 of the 534 (16.9%).
