角膜内皮营养不良有三种表现形式:(1)最常见的情况是内皮细胞于后弹力层后方产生额外的胶原。作者称此新组织为角膜后胶原层。在临床上,这一组织表现为后弹力层增厚——点状变性,多形赘疣,或灰色层。在超微结构上,该组织为原后弹力层与营养不良的内皮细胞之间的异常基膜或原纤维组织。(2)内皮细胞变大,多形,且被赘疣排挤而与后弹力层分离。在裂隙灯下以镜面反射法观察,或用反射显微镜或扫描 Corneal endothelial malnutrition has three manifestations: (1) The most common situation is endothelial cells in the posterior elastic layer produce additional collagen. The authors call this new organization the corneal collagen layer. Clinically, this tissue is manifested as thickening of the posterior elastic layer - degeneration of dots, polygons, or gray layers. In the ultrastructure, this tissue is an abnormal basement membrane or fibrillar tissue between the primitive post-elastic layer and dystrophic endothelial cells. (2) endothelial cells become larger, pleomorphic, and were squeezed out of the warts and after the elastic layer separation.
