后巩膜加固术治疗变性性近视远期疗效观察

目的:评价后巩膜加固术治疗变性性近视的远期疗效。方法:对52例行后巩膜加固术的进行性近视的患者83眼治疗资料进行术前和术后对比分析。随访观察术后6~11a视力及眼轴的变化情况。结果:裸眼视力术后8,11a均较术前提高(P<0.01);术后6~11a眼轴年平均增长长度分别为0.08,0.10,0·13mm,即年平均增长度均<0.50D。结论:后巩膜加固术可以提高视力、延缓和控制近视度数增长,改善眼底功能,减少、缓解近视严重并发症的发生,是目前治疗变性性近视最有效的方法。

Long-term clinical evaluation of posterior scleral reinforcement surgery in treatment of degenerative myopia

AIM: To observe the therapeutic effect of posterior scleral reinforcement operation on degenerative myopia. METHODS: Comparative observation on the changes of 52 cases (83 eyes) in visual acuity and axis of the eyeball was performed after 6 to 11 years’ follow-up. RESULTS: Visual acuity of all cases was significantly improved at different degrees (P<0.01). After 6 to 11 years’ follow-up, the average increased eyeball axis was 0.08, 0.10 and 0.13mm. The increased eye diopter was lower than 0.5D each year postoperatively. CONCLUSION: Posterior scleral reinforcement surgery can elevate visual acuity, delay and control the progres-sion of myopia, as well as decrease the complication of myopia. The posterior scleral reinforcement operation currently is an effective method in treatment of degene-rative myopia.
