激光近视矫正术前视网膜劈裂症的诊断及预防性激光治疗的体会

Diagnosis and preventive photocoagulation for retinoschisis before laser surgery for myopia

目的:探讨近视患者视网膜劈裂症的发生特点及预防性光凝对于激光近视矫正术的重要意义。方法:对12例22眼平均矫正视力0.82±0.13,平均屈光度6.50±3.98D的近视合并视网膜劈裂症的患者,先行术前预防性光凝,治疗后1mo再行激光近视矫正术。结果:对12例22眼患者术前行预防性光凝治疗后,后行激光近视矫正,术后无1例发生视网膜脱离。结论:对近视患者进行详细的眼底检查,借助氩激光诊断试验认识并诊断视网膜劈裂症,实施预防性光凝治疗后行激光近视矫正术是安全有效的,但需掌握近视手术的适应证。

AIM：To discuss the characteristic of retinoschisis in patients with myopia and the significance of preventive photocoagulation before laser surgery for myopia.METHODS：A total of 22 eyes in 12 patients suffering from myopia combined with retinoschisis were included.The mean best-corrected visual acuity was 0.82±0.13 and the mean preoperative spherical equivalent of the subjective refraction was 6.50±3.98D.The patients underwent preventive photocoagulation 1 month before the laser surgery for myopia.RESULTS：All the eyes that received preventive photocoagulation for retinoschisis had no retinal detachment after laser surgery for myopia.CONCLUSION：A thorough fundus examination is necessary before the surgery for myopia.The retinoschisis should be recognized and treated with preventive photocoagulation.The laser surgery for myopia is safe after preventive photocoagulation for these indicated patients.
