文档介绍：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’ followup, 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 degenerative 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[
