角膜炎是常见眼病,尽管其原因、形态(包括位置)以至病理性质多种,但从病变部位而言,不外是浅层与深层。在解剖胚胎学上,角膜前1/3层(包括上皮,上皮下层)为浅层,属身体外层膜,其后约2/3(包括实质层,内皮层)层为深层,与巩膜和葡萄膜关连。因此,前者病因多为外源性,病变亦可由结膜蔓延而来,且不导致虹膜睫状体炎,后者则可由葡萄膜和巩膜炎症波及。临床应用裂隙灯活体显微镜观察,亦可分到上
Keratitis is a common eye disease, although its causes, forms (including location) and even a variety of pathological nature, but from the lesion, nothing more than the shallow and deep. In anatomical embryology, the first 1/3 of the cornea (including the epithelium, the lower epidermis) is a superficial layer of the body’s outer membrane, followed by about 2/3 (including the parenchyma and the endothelium) Uveal related. Therefore, the former mostly etiological exogenous lesions can also be spread from the conjunctiva, and does not cause iridocyclitis, which can be affected by the uveal and scleral inflammation. Clinical application of slit lamp in vivo microscopy, can also be assigned to
