PURPOSE: To evaluate results and prognostic factors of pars-plana vitrectomy (ppv) using membrane peeling and C2F6-gas for diabetic traction retinal detachments with a hole. METHODS: We retrospectively reviewed the healing course of 84 eyes, which were treated in this way consecutively (follow-up 6-32 month). C2F6 was always used in case of a retinal hole at the posterior pole or in the upper part of the eye. The influence of HBA1c, type of diabetes, preoperative visual acuity, preoperative laser-coagulation and macular status over treatment results and rate of complications were studied using multivariate logistic regression analysis. RESULTS: Preoperatively 56% of the eyes showed premacular vitreous hemorrhage and 69% macular detachment. Using on an average 1.3 treatments in 73% retina was completely reattached and in 85% visual acuity remained unchanged or improved. The most important prognostic factors were HBA1c or = 9.3 and insufficient laser treatment. CONCLUSION: Best corrected blood sugar levels preoperatively and sufficient laser treatment seem to be very important to decrease the risk for rubeosis and repeated vitreous hemorrhages especially for patients with type I diabetes.
