后巩膜加固术治疗变性性近视远期疗效观察
【摘要】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<);术后6~,,,即年平均增长度均<。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。

Abstract 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: Visual acuity of all cases was significantly improved at different degrees (P<). After 6 to 11 years’ followup, the average increased eyeball axis was , and . The increased eye diopter was lower than each year : Posterior scleral reinforcement surgery can elevate visual acuity, delay and control the progres
sion of myopia, as well as decrease plication of myopia. The posterior scleral reinforcement operation currently is an effective method in treatment of degenerative myopia.

变性性近视是眼科致盲的主要原因之一,随病情发展,眼轴逐渐拉长,眼球扩张,从而导致玻璃体混浊、液化,视网膜、脉络膜萎缩,黄斑变性等缺血性病理改变,造成视功能成严重损害[1]。后巩膜加固术可机械性地加强巩膜,使眼球壁变厚变牢,眼轴不再继续拉长,减缓近视发展,还可通过改善脉络膜、视网膜的血液循环以提高视功能,防止或减少严重并发症的发生[2]。既往国内、外有应用巩膜加固术治疗变性性近视的文献报导[
