光导直视下巩膜扣带术治疗硅油眼视网膜脱离的临床分析

Clinical study of scleral buckling with optical fiber in retinal detachment of silicone oil-filled eyes

目的总结硅油填充眼视网膜脱离复发时应用光导直视下巩膜扣带术治疗的效果。方法对就诊于吉林大学第二医院并接受光导直视下巩膜扣带术治疗硅油眼视网膜脱离复发的12例（12只眼）患者进行回顾性分析。结果应用光导直视下巩膜扣带术治疗后网膜复位11只眼（91．7％），其中8只眼行硅油取出术后网膜保持复位。术眼均保持了一定视力，其中4只眼（33．3％）视力在0．1以上。结论对于硅油填充术后视网膜再脱离范围局限、前部PVR轻微、裂孔较明确、多位于赤道前、下方裂孔、伴有孔缘局部网膜僵硬的上方裂孔的患者，采用光导直视下行裂孔冷冻、巩膜外垫压或联合环扎术进行治疗，取得了较好的治疗效果。

Objective To summarize therapeutic efficacy of scleral buckling with optical fiber in retinal detachment of silicone oil-filled eyes. Methods we retrospectively studied the clinical materials of 12 patients （12 eyes） who suffered retinal detachment in their silicone oil-filled eyes and undergone scleral buckling with optical fiber in the second hospital. Results retina were rettachment m lleyes （91.7%） after scleral buckling operation with optical fiber. There were 8 eyes in our cases maintained retina attachment even after silicone oil was taken out. All the eyes maintained visual acuity in some degree, the visual acuity of 4 eyes （33. 3%） were above 0.1.Conclusions scleral buckling therapy with optical fiber can be effective to retinal detachment of silicone oil-filled eyes in such cases as localized detachment, slight anterior PVR, defined retinal hole, retinal hole before scleral equator, inferior hole, superior retinal hole with hard rim.
