目的：探讨不同的手术方法对巨大裂孔视网膜脱离病例的预后影响。方法：回顾１９９５年１月～１９９７年３月间我院住院治疗的巨大裂孔视网膜脱离７２例７３眼。手术方法分为四种。结果：术后随访３月，总视网膜解剖复位率为５７／７３（７８．１％），其中单纯型为１４／１６（８７．５％），复杂型为４３／５７（７５．４％）。单纯型与复杂型患眼的术后复位率无统计学差异。环扎加压术后，单纯型患眼的复位率高于复杂型。对于复杂型患眼，玻璃体手术合并环扎加压术与否对其复位率无影响；玻璃体手术中使用Ｃ１０Ｆ１８与否对其复位率无影响。结论：环扎加压术对于治疗单纯型巨大裂孔视网膜脱离，尚属一种有效的方法。Ｃ３Ｆ８气体和全氟碳液是治疗有翻转后瓣的巨大裂孔视网膜脱离的有效手段。部分复杂型巨大裂孔视网膜脱离常用硅油填充。根据患眼的具体情况，选择合适的手术方法至关重要。
Objective: To explore the different surgical methods on the prognosis of cases with huge hiatus retinal detachment. Methods: A retrospective review was performed between January 1995 and March 1997 in 72 patients (73 eyes) with giant hiatal retinal detachment in our hospital. Surgical methods are divided into four. Results: The total retinal reattachment rate was 57/73 (78.1%) after 3 months of follow-up. Among them, the simple type was 14/16 (87.5%) and the complex type was 43/57 (75.4%). . There was no significant difference in the rate of postoperative recovery between simple and complicated eyes. Cerclage compression surgery, simple type of eye reduction rate higher than the complex type. For complex type of affected eyes, vitreous surgery with or without cerclage ligation had no effect on the rate of reduction; vitreous surgery with or without C10F18 had no effect on the rate of reduction. Conclusion: Cerclage compression surgery for the treatment of simple giant retinal detachment is still an effective method. C3F8 gas and perfluorocarbon fluids are effective treatments for the treatment of giant hiatal retinal detachment with flipped valves. Part of the complex fractures of large retinal detachment commonly used silicone oil filled. According to the specific conditions of the affected eye, the selection of appropriate surgical methods is crucial.
