结膜下出血
结膜(conjunctiva)为衬贴于眼睑内面和眼球表面的一层柔软、光滑而透明的薄膜。在正常活体上,结膜红润,透过之可观察到其深面的毛细血管;不同程度贫血,可见结膜变浅或变苍白;在炎症时,结膜充血,称为结膜炎,是临床常见病、多发病。
结膜根据其分布部位不同,可分为睑结膜和球结膜。睑结膜覆盖眼睑的内面;球结膜覆盖眼球巩膜的表面,前端附着于角膜巩膜缘,二者在眼球的后部相互延续形成结膜穹,分别为结膜上、下穹。当闭眼时,形成密闭的结膜囊,保护眼球,并协助将泪液引流到泪道。 |

结膜
为覆盖在上、下眼睑内面和巩膜前部的一层粘膜。在眼睑内面的称睑结膜,在巩膜前部的称球结膜,在两部之间的移行区称结膜穹窿(此区为沙眼的好发区)。此膜具有保护和便于眼球移动的作用。 |
