PURPOSE
A retrospective study was performed to determine the incidence of retinal detachment after extracapsular cataract extraction in high myopia and the risk factors associated with the occurrence of retinal detachment.
METHODS
Of the 463 patients (463 eyes) who had undergone extracapsular cataract extraction with or without intraocular lenses implant between July 1993 and January 1994, 90 patients companied with high myopia and the others were senior cataract. All patients had been followed up for 27 to 33 months.
RESULTS
One (1.11%) developed retinal detachment in the patients with high myopia, and no retinal detachment occurred in the patients with senior cataract. The difference of the incidence of retinal detachment between two groups were no significant (P > 0.05), More myopic patients underwent Nd:YAG laser capsulotomy (P < 0.05).
CONCLUSION
Comparing with intracapsular method, extracapsular cataract extraction decreased the risk of retinal detachment even in the high myopic patients. The risk factors for retinal detachment were young patients, long eye axis and posterior capsulotomy.
目的
进行一项回顾性研究，以确定高度近视患者白内障囊外摘除术后视网膜脱离的发生率以及与视网膜脱离发生相关的危险因素。
方法
在1993年7月至1994年1月间接受白内障囊外摘除术（有或无人工晶状体植入）的463例患者（463只眼）中，90例为高度近视患者，其余为老年性白内障患者。所有患者均随访27至33个月。
结果
高度近视患者中有1例（1.11%）发生视网膜脱离，老年性白内障患者未发生视网膜脱离。两组视网膜脱离发生率的差异无统计学意义（P>0.05），更多近视患者接受了Nd:YAG激光后囊切开术（P<0.05）。
结论
与囊内摘除法相比，白内障囊外摘除术即使在高度近视患者中也降低了视网膜脱离的风险。视网膜脱离的危险因素为年轻患者、眼轴长和后囊切开术。
