Objective To investigate clinic effects of external microsurgery and conventional external surgery in treatment of rhegmatogenous retinal detachment and to compare the safety. Methods A total of 98 patients with rhegmat-ogenous retinal detachment admitted from January to December 2016 were divided into control group (n=49) and obser-vation group (n=49). Control group was given conventional external surgery, while observation group was given external microsurgery. Clinic effect and incidence rate of complication rate were compared in two groups. Results In control group, no new holes were found during operation, and holes in 4 patients were missed after operation; in observation group, holes in 6 patients were found during operation, and hole in 1 patient was missed after operation;the differences between two groups were statistically significant (P<0. 05). There were no significant differences in application condi-tions of surgical implants, incidence rate of postoperative complications, recovery of visual acuity and complete anatomi-cal reduction of retina between the two groups (P>0. 05). In observation group, operative time was significantly shorter, while excellent and good rate of condensation was significantly higher than those in control group (P<0. 05). Conclu-sion External microsurgery in treatment of rhegmatogenous retinal detachment can achieve better curative effect than that by traditional external operation, and it also has better security.%目的 探讨显微外路手术和传统外路手术治疗裂孔源性视网膜脱离的临床疗效,并对比分析其安全性.方法 选取2016年1月—12月收治的98例裂孔源性视网膜脱离作为研究对象.按治疗方法将分为对照组和观察组,每组49例,对照组采取传统外路手术治疗,观察组采取显微外路手术治疗.对比分析两组的临床疗效和并发症发生率.结果 对照组术中未发现新裂孔,术后遗漏裂孔4例;观察组术中发现新裂孔6例,术后遗漏裂孔1例;两组比较差异有统计学意义(P<0.05).两组外植入物应用情况、术后并发症发生情况、视力恢复程度以及视网膜完全解剖复位情况比较差异无统计学意义(P>0.05).观察组手术时间短于对照组,冷凝程度良好率高于对照组(P<0.05).结论 显微外路手术治疗裂孔源性视网膜脱离的临床疗效优于传统外路手术,且具有较高的安全性.
