摘要
目的:评估近视眼准分子激光原位角膜磨镶术(LASIK)前预防性激光光凝治疗视网膜裂孔的有效性和安全性。方法:2000-04/2004-04,共对1233例近视患者1845眼在LASIK术前用间接眼底镜行全面的眼底检查。根据是否存在视网膜裂孔分为组Ⅰ(有裂孔者)和组Ⅱ(无裂孔者),并于LASIK术前对所有有裂孔眼包括无症状者进行预防性的激光光凝术处理。结果:本组患者年龄为18～43(25.3±5.7)岁,平均术前等量球镜近视(PSER)度数为(-7.44±2.13)D(-1.50～-14.50)D。组Ⅰ32例37眼(2.05%)确诊有视网膜变性裂孔并进行了光凝治疗;组Ⅱ1201例1808眼没有发现视网膜裂孔。两组患者在年龄和性别上没有统计学差异(P>0.05);组Ⅰ的平均PSER为(-9.41±4.15)D,组Ⅱ为(-7.52±3.71)D,两组间平均PSER统计学处理有显著性差异(P<0.05)。术后平均随诊14mo,没有出现视网膜脱离病例。结论:预防性激光光凝手术治疗干性视网膜裂孔是有效和安全的;近视眼LASIK手术前应进行全面的视网膜检查并对裂孔行视网膜光凝治疗。
AIM： To assess the efficacy and safety of prophylactic laser photocoagulation for retinal breaks before laser in situ keratomileusis （LASIK） in myopic eyes.
METHODS： From April 2000 to April 2004, totally 1 845 eyes （ 1 233 patients ） requesting LASIK had a fundus examination with indirect ophthalmoscopy before the surgery. They were divided into two groups according to the presence （Group 1） or absence of retinal breaks （Group 2）. All patients with retinal breaks, though they were asymptomatic, underwent prophylactic laser photocoagulation to seal the breaks before LASIK.
RESULTS： Patient age ranged from 18 to 43 （ 25.3±5.7） yaers old. Mean preoperative spherical equivalent refraction （PSER） was -7.44± 2.13 D （range, -1.50 to -14. 50 D）. Retinal breaks were identified and treated in 37 eyes （2.05%） of 32 patients; 1 808 eyes of 1 201 patients had no retinal breaks. No statistical difference was found in age （ P 〉0.05） or gender （P 〉0.05） between the two groups. Significant difference of PSER was noted between Group 1 （-9.41±4.15D） and Group 2 （-7.52±3.71D） （P〈0.05）. During a mean 14mo follow-up, none of the patients developed retinal detachment.
CONCLUSION： The efficacy and safety of prophylactic laser photocoagulation for retinal breaks was confirmed. Retinal breaks should be identified and treated by photocoagulation in eyes before LASIK for myopia.
