玻璃体切除术治疗人工晶状体眼视网膜脱离

Clinical study of vitrectomy for pseudophakic retinal detachment

目的探讨以玻璃体切除术治疗人工晶状体眼视网膜脱离的临床效果。方法对50例（50眼）人工晶状体眼视网膜脱离施用玻璃体切除术。其中16眼行硅油填充术，34眼行C3F8眼内填充。术后随访6～24月。结果术后视网膜最终完全复位49眼（98．00％）。15眼（30．00％）术中新发现裂孔。术后视力均有不同程度的提高。结论玻璃体切除术治疗人工晶状体眼视网膜脱离具有术野清晰、易于寻找隐匿性裂孔、提高视网膜复位率及复发率低的优点。

Objective To study the vitrectomy for treatment of pseudophakic retinal detachment. Methods The vitrectomy was performed in 50 cases for pseudophakic retinal detachment with a standardized procedure. The vitreous cavity was tamponaded with silicone oil in 16 eyes and C3F8 in other 34 eyes.The postoperative follow-up time was 6 - 24 months. Results The total retinal reattachment was in 49 eyes （98%） New retinal breaks were identifed in 15 eyes intraoperatively.All eyes visual acuity was improved after operation. Conclusions The main advantage of vitrectomy for pseudophakic retinal detachment isbetter intraoperative sight to find the occult retinal breaks in peripheral fundus, to improve the rate of retinal reattachment, to decrease the rate of retnal redetachment and to improve the visual function after vitrectomy. The vitrectomy is a safe, effective clinical treatment for pseudophakic retnal detachment.
