目的：评价视网膜切开和切除（简称切开手术）对复杂性视网膜脱离（ｃｏｍｐｌｉｃａｔｅｄｒｅｔｉｎａｌｄｅｔａｃｈｍｅｎｔ，ＣＲＤ）的治疗价值和效果。方法：用玻璃体切除、视网膜切开或切除、全氟三丁烷胺液（重水）、眼内光凝及硅油填充等治疗３８只眼ＣＲＤ病例。结果：出院时视网膜保持复位９２．１％，随访３～１２个月（平均５．５个月），解剖复位率６６．３％；视力数指以上５７％，最好视力为０．２。结论：切开手术能治愈用常规玻璃体视网膜手术（ｖｉｔｒｅｏ－ｒｅｔｉｎａｌｓｕｒｇｅｒｙ，Ｖ－Ｒ）不能治愈的ＣＲＤ病例；适用于为了到达视网膜下间隙，去除视网膜下膜和松解视网膜的牢固牵引。
Objective: To evaluate the therapeutic value and effect of retinal detachment and resection (CRA) on complicated retinal detachment (CRD). Methods: Thirty-eight CRD cases were treated with vitrectomy, retinal incision or resection, perfluorotributylamine solution (heavy water), intraocular photocoagulation and silicon oil filling. Results: At the time of discharge, the retina was maintained at 92.1%, followed up for 3 to 12 months (average 5.5 months). The anatomic reduction rate was 66.3%. The visual acuity was 57%. The best visual acuity was 0.2. CONCLUSIONS: Open surgery can cure CRD cases that can not be cured with conventional vitreo-retinal surgery (V-R); it is suitable for the removal of subretinal and lytic retinal firm traction in order to reach the subretinal space.
