A clinical study on diabetic retinopathy.

A clinical research on the diabetic retinopathy(DR) is reported. In the 662 cases of diabetes mellitus examined, the prevalence of DR was 51.3%, of which 7.6% were preproliferative and 7% proliferative. The study showed that when the disease progressed to the preproliferative and proliferative DR, laser photocoagulation could be the best treatment of choice, and panretinal photocoagulation was also quite effective in the treatment of pregnant patients with proliferative diabetic retinopathy.
