目的:观察并统计准分子手术前眼底检查出视网膜变性的比率,探讨手术前检查对术后并发症防治的临床意义。方法:对2007-01/2008-01术前扩瞳检查1128例1128眼眼底情况进行分析,对比低、中、高度近视发生视网膜变性的几率,进行激光治疗及手术情况,平均随访1～15mo。结果:所选1128眼发现视网膜变性需激光治疗者48眼,视网膜干性裂孔20眼。结论:视网膜变性是近视眼最为常见的一种并发症,如果不及时处理,可以导致视网膜脱离等一系列严重损害视功能的后遗症,因此手术前的筛查对预防并发症的发生有极其重要的意义。

AIM:To observe the ratio of retinal degeneration by fundus examination before LASIK surgery,and to evaluate the clinical significance of pre-operative examination for prevention and treatment of postoperative complications.·METHODS:Totally 1128 patients with preoperative pupil dilation were examined and analyzed from January 2007 to January 2008. The risk of retinal degeneration,laser treatment and surgery condition were observed and compared in the low,middle and high myopic patients. All patients were followed up for 1 to 15 months.·RESULTS:Retinal degeneration with laser treatment were in 48 cases,and retinal dry hole in 20 cases. ·CONCLUSION:Retinal degeneration is the most common complication of myopic patients,if not treated in time,it can cause a series of after-effects including retinal detachment.It is very important to prevent complications by sieving before surgery.
