目的:观察准分子屈光手术患者术前周边视网膜变性情况,以及进行预防性激光光凝的疗效。方法:对所有患者术前扩瞳后以78D前置镜、三面镜详细检查眼底周边视网膜情况并记录,对严重的视网膜病变等予以532nm激光光凝治疗,经随访稳定有效后再择期手术。结果:近视度数越高周边部眼底病变的发生率越高,周边部视网膜变性在颞侧的发生率最高。结论:近视屈光术前进行仔细的周边眼底检查很重要,对明确有视网膜变性或伴干性裂孔的近视患者应预防性532nm激光光凝疗。

AIM:To investigate the therapeutic effects of preventive laser photocoagulation for myopia patients with peripheral retinal degeneration or holes before LASIK operation. METHODS:Before operation,the fundus was examined with direct and indirect ophthalmoscope and three-mirror contact lens.The 532nm laser photocoagulation was performed in order to strengthen the retina with severe peripheral degeneration. RESULTS:Peripheral fundus abnormalities and holes both increased with increased refraction diopter.The abnormalities were usually in the temporal fundus. Patients were followed up for 10 months,and no rhegmatogenous retinal detachment was found. CONCLUSION:It is necessary to know the retinopathy before operation.Preventive 532nm laser photocoagulation for moderate and high myopia patients,who were confirmed to have peripheral retinal degeneration or retinal holes before LASIK operation,is very necessary.
