Objective To investigate the effect of prophylactic 360°laser retinopexy on retinal redetachment after silicone oil removal. Methods The clinical data of 181 vitreoretinal patients after silicone oil removal were retrospectively analyzed. In 88 patients (photocoagulation group) was taken prophylactic 360-degree laser retinopexy before silicone oil removal; in 93 patients (control group) without prophylactic laser retinopexy. The incidence, time, the cause of retinal redetachment and the complications of laser retinopexy after silicone oil removal in two groups were observed. Results The duration of silicone oil tamponade is 4~72 weeks, averaging 13.7±2.4 weeks. 20 cases of retinal redetachment were recorded after silicone oil removal, including 5 cases (5.7%) in photocoagulation group and 15 cases (16.1%) in control group. The difference between two groups is statistically significant (P lt;0.05). Among these 20 patients with retinal redetachment, 10 occured during the first 3 days after the operation, 6 during 4~7 days, 3 during 8~14 days. 1 case occured 2 months after the operation. 11 cases of redetachment result from the omission of small retinal breaks located in ora serrata or behind the photocoagulation zone, or the reopening of primary retinal breaks because of insufficient photocoagulation and freezing during the operation. 1 case result from the hole that come from laser photocoagulation scar tracted by nearby proliferative tissue. 7 cases result from the formation of new breaks from the proliferative vitreoretinopathy(PVR) or proliferation of residual vitreous. There are 52 cases of burning of pupillary border, with the incidence of 59%. Conclusions Prophylactic 360-degree laser retinopexy is associated with a decrease of the incidence of retinal redetachment after removal of silicone oil. （Chin J Ocul Fundus Dis，2008，24：283-285）
