A Clinical Study on the Silicone Oil in the Treatment of Proliferative Diabetic Retinopathy

ABSTRACT

PURPOSE: To evaluate the surgical results and complications in vitrectomy with silicone oil tamponade for the treatment of proliferative diabetic reitnopathy(PDR). METHODS: Vitreous microsurgery with silicone oil tamponade was performed on 21 patients with advanced proliferative diabetic retinopathy. RESULTS: Anatomic attachment was maintained in 19 eyes(90.5%). Functional success with visual acuity 0.02 or better was found in 17 eyes(81.0%). Functional failures were caused by retinal detachment in 2 eyes and glaucoma in 2 eyes. Complications of silicone oil included cataract in 8 of 14 phakic eyes(57.1%), epiretinal proliferation in 7 of 21 eyes(33.3%), retinal detachment in 6 eyes(28.6%), silicone oil in anterior chamber in 3 eyes(14.3%), secondary glaucoma in 2 eyes(9.5%), and emulsification of silicone oil in 2 eyes(9.5%). CONCLUSION: Vitrectomy with silicone oil was highly effective in advanced proliferative diabetic retinopathy and early removal of silicone oil was recommended to reduce the complications of silicone oil.
