style=\";font-family:宋体;line-height:200%;font-size:16px\">(2)玻璃体液化(fluidity of vitreous body)：玻璃体液体是玻璃体由凝胶状态变为溶解状态，是玻璃体新代谢障碍所引起的胶体平衡破坏。亦以高度近视及老年患者为常见。液化一般从玻璃体中央开始，出现一光学空间，逐渐扩大，也可以多个较小液化腔融合成一较大的液化腔。液化腔内有半透明灰白色丝束样或絮状物飘浮晃动。</span></p><p

style=\";font-family:宋体;line-height:200%;font-size:16px\">(1)与近视眼的关系：视网膜脱离多发生于近视眼患者。在较大样本孔源性视网膜脱离病例中，近视屈光度在-6.00D以上的病人很多。近视眼中孔源性视网膜脱离的发病年龄较正视眼者轻。近视眼的病变主要在眼球的后节，自赤道起始，眼球后节渐渐扩张，脉络膜的毛细血管层萎缩变薄甚至消失，视网膜也继发变性、萎缩，同时玻璃体也出现液化。具有这些致病因素便容易发生视网膜脱离。</span></p><p

style=\";font-family:宋体;line-height:200%;font-size:16px\">(2)眼外肌运动的影响：4条直肌的止端位于锯齿缘前，其运动对视网膜的影响不大。而斜肌止于眼球的后部，上斜肌牵拉眼球下转，再加玻璃体的重力作用，可能与颞上象限视网膜容易产生裂孔有一定关系。黄斑部易发生囊样变性，可以继发成裂孔，有人认为也与下斜肌运动时的牵拉有关。有人观察了286例视网膜脱离手术时裂孔的分布情况，发现68.4%的裂孔在视网膜的颞侧，其中47.49%与上、下斜肌止端的位置相对应，即裂孔在颞上象限，右眼多集中于10～11点钟，左眼1～2点钟方位，角膜缘后13～15mm处。此外还常在11～1点钟方位，角膜缘后16～22mm处出现大马蹄形裂孔。颞下象限的裂孔比较集中在右眼8～9点钟和左眼的3～4点钟，角膜缘后16.46～26mm处，呈前后水平走行。</span></p><p

style=\";font-family:宋体;line-height:200%;font-size:16px\">(3)与眼外伤的关系：眼球受钝挫伤后发生锯齿缘断离，可发展成视网膜脱离。青少年眼外伤在视网膜脱离中的患病率较高，占18.71%～20%。动物实验证实，在眼球挫伤的瞬间，眼球变形可引起视网膜远周边部发生撕裂。此外，重度外伤可直接在赤道部产生视网膜裂孔。外伤引起的后极部毛细血管循环淤滞、视网膜振荡与玻璃体牵引，可发生黄斑裂孔或由黄斑囊样变性进而发展成孔。除这些与外伤有明确关系的视网膜脱离外，其他大多数病例，多半是视网膜和玻璃体已有变性或粘连，具备了视网膜脱离的内在因素，外伤仅作为诱因诱发了视网膜脱离的发生。</span></p><p
