Clinical observation of laser photocoagulation before laser in situ keratomileusis with retinal degeneration
［Abstract］ Objective To investigate the effect of argon laser photo coagulation before laser in situ keratomileusis(LASIK) with retinal degeneration in assuring the success of operation. Methods Patients with myopia were regularly examined with direct ophthalmoscope and Goldmann three mirror contact lens preoperatively，144 patients (168 eyes)with retinal holes or severe degeneration were treated by argon laser photocoagulation first，as therapeutics.Two weeks later after retinal holes or degeneration closed well，LASIK was performed.As for controls，108 patients(126 eyes)with slight retinal degeneration were followed up to observe the change of retina after LASIK and treated by argon laser pho免费论文网 【http://www.51lunwen.net】tocoagulation if necessary.All the patients were followed up for 12 months after LASIK. Results retina were stable in the 168 eyes of the therapeutic group，while in the control group of 126 eyes，6 eyes were treated by argon laser photocoagulation and 1 eye was treated by the surgery of retinal detachment after LASIK. Conclusion For the myopic patients confirmed with retinal holes or degeneration， argon laser photocoagulation before LASIK was an important method to prevent retinal detachment after LASIK and assure the success of operation.

LASIK在近视眼患者治疗中的有效性、安全性以及良好的可预测性已在临床得到证实［1］。随着手术患者的增加，LASIK术后发生视网膜脱离的报道逐渐增多［2~4］，已经引起眼科屈光医师和近视眼患者的广泛关注。本对我院眼科中心2002年1月~2005年1月LASIK术前通过充分散瞳三面镜检查发现有明确周边视网膜变性或伴干性裂孔的近视眼患者，进行氩 离子激光预防性视网膜光凝，并探讨LASIK术前预防性光凝对视网膜稳定性的影响，现报告如下。
1 资料与方法
1.1 一般资料 我院眼科中心2002年1月～2005年1月LASIK术前发现有明确周边视网膜变性或伴干性裂孔的近视眼患者，行氩离子激光治疗者144例（168眼）为治疗组，未行氩离子激光治疗者108例（126眼）为对照组。治疗组男66例（72眼），女78例（96眼），年龄18～46岁，平均（26.3±5.7）岁。对照组男48例（57眼），女60例（69眼），年龄18～42岁，平均（25.2±4.8）岁。治疗组和对照组屈光状态分布及视网膜病变类型，见表1、表2。治疗组和对照组均随诊12个月。 表1 LASIK术前治疗组视网膜病变情况 表2 LASIK术前对照组视网膜病变情况 （略）
