高度近视周边视网膜变性的预防性激光治疗

Preventive treatment of peripheral retinal degeneration of high myopia by laser photocoagulation

目的 观察高度近视眼的周边视网膜变性和／或裂孔进行预防性光凝的疗效。 方法 散瞳检查高度近视眼眼底，发现周边视网膜变性和／或裂孔２０６ 只眼，予以预防激光治疗。 结果 实行视网膜变性预防性光凝的患者，接受ＬＡＳＩＫ手术后，随访一年无一例发生视网膜脱离，矫正视力没有变化。 结论 视网膜变性激光预防性光凝对预防视网膜脱离至少在角膜屈光手术后近期观察中是安全有效的方法。

Objective To observe the effect of laser photocoagulation of the peripheral retinal holes and/or degeneration in high myopia. Methods Full fundus examination for high myopic patients was made before keratorefractive surgery with binocular indirect ophthalmoscopy.Peripheral holes,degeneration and vitreous traction were found in 206 eyes of 135 patients,and all of them were treated with laser photocoagulation. Results No retinal detachment occurred after keratorefrative operation within 1 year follows up. Conclusions Retinal laser photocoagulation is an effective and safety method before keratorefractive operation for prevention of the retinal detachment in high myopia at least in short term observation.
