角膜水肿在临床上不少见,可以自然发生或出现于内眼手术后。损害视力。目前对其病理生理学有较明确的了解。本文复习了角膜水肿的现代知识和治疗的发展。一、角膜水化的生理角膜水肿的形成与身体其它部分组织液体异常集聚不同。角膜无血管,因此它的水化状态的改变与血管渗透性的改变无关。角膜有五层结构,包括厚的实质,主要是胶元纤维排列为200→250板层,它们彼此并与表面互相平行。现已知角膜的透明是取决于胶元纤维的规则排列。表面为复层上皮及前弹力膜,内壁有一单层上皮及后弹力膜。它沐浴在外界的泪幕
Corneal edema is not uncommon in clinical practice, can occur spontaneously or after intraocular surgery. Damage vision. There is a clear understanding of its pathophysiology. This article reviews the development of modern knowledge and treatment of corneal edema. First, corneal hydration physiological corneal edema and other parts of the formation of abnormal tissue fluid accumulation. The cornea is avascular, so changes in its hydration state are not associated with changes in vascular permeability. The cornea has a five-layer structure, including thick parenchyma, mainly collagen fibers arranged in 200 → 250 plies that are parallel to each other and to the surface. It is known that the transparency of the cornea depends on the regular arrangement of the collagen fibers. The surface of the stratified epithelium and the former stretch membrane, the inner wall has a single layer of epithelial and post-stretch membrane. It is bathed in the tears of the outside world
