目的:探讨孔源性视网膜脱离行巩膜扣带术后,影响其视力恢复的相关因素。方法:回顾性分析孔源性视网膜脱离患者102例102眼,均行一次巩膜扣带术成功治疗视网膜脱离。术后随访3～6mo,观察术后最佳矫正视力,χ2检验用于分析影响视力恢复的相关因素。结果:黄斑是否脱离、术前最佳矫正视力、视网膜脱离范围及术中是否行视网膜下放液均与术后最佳矫正视力相关(P<0.01)。黄斑脱离在1wk内与1wk以上术后视力恢复差异有统计学意义(P<0.05)。结论:黄斑是否脱离及脱离时间、术前最佳矫正视力、视网膜脱离范围和术中放液是影响术后视力恢复的重要因素,术前应详细分析病情,术中尽可能避免行视网膜下放液。

AIM:To discuss the relative risk factors affecting visual recovery after scleral buckling surgery in rhegmatogenous retinal detachment.METHODS:A total of 102 cases(102 eyes)with rhegmatogenous retinal detachment treated by scleral buckling surgery in our hospital were retrospectively analyzed.Patients were followed up for 3 to 6 months,and the best-corrected visual acuity(BCVA)was observed.The Chi-square test was used to analyze the relative factors affecting the visual recovery.RESULTS:Macular detachment status,preoperative BCVA,quadrants of retinal detachment,as well as subretinal fluid drainage affected visual recovery significantly(P<0.01).Eyes with macula-off ≤7 days had a significantly lower BCVA compared to eyes with macula-off>7 days(P<0.05).CONCLUSION:Macular detachment status and time,preoperative visual acuity,quadrants of retinal detachment,as well as subretinal fluid drainage affect visual recovery significantly.Subretinal fluid drainage should be avoided as far as possible.
