引起角膜血染症的主要原因有2个:(1)在持续高眼压下的严重前房出血时,红细胞崩解产物通过内皮细胞移行到实质内,引起弥蔓性的血染症。(2)由于各种原因的角膜实质内新生血管出血,引起限局性的血染症。虽然出血初期是红色的,但是慢慢随着吸收而变为褐色。在实质组织中出现的红细胞变性崩解,一旦被实质细胞或游走细胞吞噬吸收,则血红蛋白也被破坏,最初在这些细胞内产生含铁血黄素。后这些细胞自体也变性崩解。电子显微镜观察,虽然红细胞崩解产物最初在角膜实质的胶原纤维间被 There are two main causes of corneal blood stained disease: (1) In severe hyphema under continuous high intraocular pressure, erythrocyte disintegration products migrate through the endothelial cells to the parenchyma, causing diffuse bloodborne disease. (2) due to a variety of reasons corneal neovascularization within the essence of bleeding, causing the bloody limit of the situation. Although the initial bleeding is red, but slowly with the absorption and brown. The red blood cell degeneration that disintegrates in the parenchymal tissue, once engulfed by the parenchymal or migratory cells, also destroys hemoglobin, initially producing hemosiderin in these cells. After these cells themselves also degeneration. Electron microscopic observation showed that although erythrocyte disintegration products were initially trapped between corneal collagen fibers
