We evaluated the prognostic value of the vitreous in 735 eyes of 379 patients with diabetic retinopathy. Initially, the eyes showed complete posterior vitreous detachment (PVD) in 9%, partial PVD in 24% and no PVD in 67%. All the 68 eyes with complete PVD remained in nonproliferative stage throughout the follow-up period averaging 37 months. Panretinal photocoagulation (PRP) was performed in 54% of the 68 eyes. No eyes required vitrectomy. Final visual acuity was 0.4 in average. Maculopathy was resposible for poor vision below 0.1. Among the 172 eyes with partial PVD, 98% were initially categorized as proliferative diabetic retinopathy. PRP was performed in 86% and vitrectomy in 77%. Final visual acuity was 0.08 in average. Poor vision was due to maculopathy in 27% and tractional retinal detachment in 38%. In 495 eyes with no PVD, 60% showed proliferative retinopathy at the beginning. One-half of eyes with nonproliferative retinopathy progressed to proliferative one during the follow-up. PRP was performed in 89% and vitrectomy in 29%. Final visual acuity was 0.4. Poor vision below 0.1 was due to maculopathy in 64% and tractional retinal detachment in 12%. The study shows that the initial state of the vitreous determines the course of retinopathy and visual outcome in diabetic retinopathy even under treatment.
