SINCE the advent of insulin therapy enabling survival of patients with diabetes, diabetic retinopathy has become and has remained one of the leading causes of incurable blindness. Both internists and ophthalmologists are haunted by the specter of diabetic retinopathy resulting in a hopelessly blind patient. Lack of effective treatment has prompted many therapeutic trials.
