Retinal evaluation was performed in 20 consecutive type 2 diabetics before and after renal transplantation. This included 19 men and 1 woman of mean age 52 years (range 30 to 60 years). Before renal transplantation, 95% of these patients showed diabetic retinopathy (50% nonproliferative and 45% proliferative diabetic retinopathy). There was no change in retinopathy at 3 months after renal transplantation. At 1 year, two patients (10%) showed deterioration in their diabetic retinopathy, while the remaining 90% did not show any change. Also 25% of renal allograft recipients developed posterior capsular cataracts.
