倒睫的临床表现及治疗

来源:华人健康网 | 发布时间:2010-12-10 10:07:29 | www.chinesejk.com

  倒睫

  倒睫是指睫毛倒向眼球,刺激角膜和球结膜的一种睫毛位置异常。常与眼睑内翻同时存在,但也可以只有倒睫而无内翻者。倒睫的原因常是由于眼睑内翻,睑缘炎特别是溃疡性睑缘炎后引起的毛囊部瘢痕收缩的结果。此外,眼睑赘皮等都是倒睫的常见原因。

  [临床表现]

  患者自觉磨痛、怕光、流泪。检查时,可见部分或大部分踺毛向内(贴近眼球)倾倒,接触角膜或结膜,眼睑痉挛(闭眼难睁),结膜充血,角膜上皮剥脱(一般需在放大镜或裂隙灯显微镜下观察方可察觉),甚至出现角膜混浊、角膜溃疡、角膜上长有新生血管。
