Management of complicated retinal detachment by vitrectomy and silicone oil injection.

One hundred eyes of 95 patients were operated with vitrectomy and silicone oil injection. The patients were divided into 3 groups: Penetrating trauma (PT)-22 eyes, proliferative diabetic retinopathy (PDR)-14 eyes, and proliferative vitreoretinopathy (PVR)-64 eyes. All of the eyes had retinal detachment including the macula. Final attachment of the retina was achieved in 40% of PT, 50% of PDR, and 60% of PVR. Improvement of visual acuity following the operation was noted in 54% of PT, 43% of PDR, and 67% of PDR. Postoperative complications included band keratopathy, elevation of IOP, hypotony, and cataract. Neovascularization of the iris, either preoperative or postoperative, is associated with very poor prognosis.
