We reviewed 79 cases(133 eyes) of diabetic retinopathy which were treated by panretinal photocoagulation(PRP) and, if necessary, additional treatments, to find the factors which influence either regressed or persisted neovasculization and cause late vitreous hemorrhage after laser treatment. After PRP, 21 eyes(16%) gained 2 or more lines, 64 eyes(48%) were within 1 line and 48 eyes(36%) lost 2 or more lines of visual acuity. After PRP, neovasculization was regressed in 39 eyes and persisted in 42 eyes. Vitreous hemorrhage occurred in 22 eyes at 9.4 months after completion of initial PRP on the average. The duration of diabetes, the level of fasting blood glucose and the presence of neuropathy, nephropathy or hypertension showed no statistically significant correlation to persisted neovasculization or vitreous hemorrhage after laser treatment.
