Indications for silicone oil injection included perforating trauma (9%), proliferative diabetic retinopathy (PDR) (6.7%), giant tear (7.8%), and rhegmatogenous retinal detachment (RRD) (76.5%). After SOR, RRD, keratopathy, persistent hypotony, and elevated IOP occurred at rates of 21.3%, 11.2%, 10.1%, and 9%, respectively. Eyes with preoperative hypotony were significantly more likely to have persistent hypotony and a poor visual prognosis. DISCUSSION. Our results provide a thorough contemporary analysis of the visual prognosis and complication rates after SOR. Avoiding SOR with long-term silicone oil retention may be advisable in hypotonous eyes.
