Incidence of rhegmatogenous retinal detachment after vitrectomy in eyes of diabetic patients.

PURPOSE: To assess the incidence of rhegmatogenous retinal detachment (RRD) after pars plana vitrectomy (PPV) among diabetic patients with complications of proliferative diabetic retinopathy.

METHODS: Ninety-three eyes of diabetic patients-who underwent PPV with or without intraocular gas tamponade for complications of proliferative diabetic retinopathy-were reviewed retrospectively. Indication for vitrectomy was vitreous hemorrhage in 80 patients (86.1%), tractional retinal detachment in 3 (3.2%), and vitreous hemorrhage associated with tractional retinal detachment in 10 (10.7%).

RESULTS: Four (4.3%) of 93 eyes developed an RRD after vitrectomy. The primary reason for vitrectomy was recurrent or nonresolving vitreous hemorrhage. The retina was attached with one additional surgical procedure in two of these eyes; the other two had to undergo a third operation before attachment was achieved.

CONCLUSION: RRD occurs in a small percentage of patients after PPV with or without gas tamponade for vitreous hemorrhage or tractional retinal detachment caused by proliferative diabetic retinopathy. Thorough postoperative follow-up is important to make early diagnosis and intervention possible.
