目的 :探讨视网膜脱离继发黄斑裂孔的原因 ,手术方法、特点和疗效。方法 :11例患者均在局麻下行常规视网膜脱离复位手术。间接检眼镜直视下冷冻周边裂孔 ,硅胶带环扎或外加压 ,放液 ,注气。结果 :所有患者随访 6月～ 2年 ,视网膜复位良好 ,黄斑孔贴附。最终视力均在 0 .0 2以上 ,其中≥ 0 .0 5者 9例 ,最好视力 0 .2。结论 :视网膜脱离继发黄斑裂孔的形成可能与视网膜急性缺氧 ,黄斑囊变有关。手术关键是封闭周边裂孔 ,配合气体填充 ,术后黄斑孔不必激光封闭。此种手术方法简单 ,成功率高 ,术后视力能得到一定程度改善。
Objective: To investigate the causes, surgical methods, features and curative effects of secondary macular hole with retinal detachment. Methods: All the 11 patients underwent routine retinal detachment under local anesthesia. Indirect ophthalmoscopy under the frozen peripheral holes, silicone band cerclage or external pressure, liquid, gas injection. Results: All patients were followed up for 6 months to 2 years. The retinal reattachment was good and macular holes were attached. The final visual acuity were more than 0. 02, of which ≥ 0. 0 5 in 9 cases, the best visual acuity of 0.2. Conclusion: The formation of macular hole secondary to retinal detachment may be related to retinal acute hypoxia and macular degeneration. The key is to close the surgical hole around the hole, with gas filling, macular hole postoperative laser without closure. This surgical method is simple, high success rate, postoperative visual acuity can be improved to some extent.
