Abstract: :
Purpose: To evaluate the clinical efficacy for early application of the silicone oil in patients that vitrectomy with primary silicone oil injection was performed in the severe proliferative diabetic retinopathy. Methods: We did retrospective clinical analysis on the preoperative and postoperative retinal findings, visual results, postoperative complications in 26 patients (30 eyes) with severe proliferative diabetic retinopathy who vitrectomy and silicone oil injection was performed simultaneously. Results: Vitrectomy with silicone oil injection was performed in 14 eyes(46.7%) with severe traction retinal detachment involving macula, 10 eyes(33.3%) showed severe hemorrhage of the cases that iatrogenic retinal tear was developed in the eyes with traction retinal detachment and 6 eyes(20.0%) with combined tractional and rhegmatogenous retinal detachment, and silicone oil was removed on mean 2.65 months(1.4∼6.0 months) in 28 eyes of a total of 30 eyes, postoperatively. After surgery, final anatomic success was obtained in 26 eyes(86.7%) and functional success in 23 eyes(76.7%). There was visual improvement of mean 2.8, 1.9 lines and improvement over 2 lines in 17(56.7%), 11(36.7%) eyes for best and final visual acuity comparing to preoperative visual acuity, respectively. Postoperative complications included cataract formation and aggravation in 24 or 25 phakic eyes(96.0%), membrane reproliferation in 10 eyes(33.3%), retinal detachment in 10 eyes(33.3%), neovascular glaucoma in 5 eyes(16.7%), vitreous hemorrhage in 3 eyes(10.0%), and phthisis, band keratopathy, endophthalmitis in 1 eye (3.3%) respectively. Conclusions: In the proliferative diabetic retinopathy that difficulty in the retinal reattachment is predicted or that has high risk of the rebleeding, early application of the silicone oil is expected to be useful tool.
