据一些统计调查,我国主要致盲的眼病依次为角膜白斑、青光眼、白内障和眼外伤等,而角膜白斑和白内障分别有47％和81％为可治盲。现简要讨论如下。一、角膜白斑:眼球最前面是一层透明的角膜,它很容易受伤或因炎症感染形成角膜溃疡,成为角膜白斑的主要原因。其他如婴幼儿缺乏维生素A所致的角膜软化症合并感染,也会遗留角膜白斑;严重的角膜变性,能阻碍光线进入眼内,甚至使光线完全不能透入眼内,以致造成失明,这些仅占极少数。角膜白斑患者,如果光觉和色觉正常,说明病人眼底(包括视神经和视网膜)是健康的,仅仅是角膜混
According to some statistical surveys, the main blinding eye diseases in our country are corneal leukoplakia, glaucoma, cataracts and ocular trauma, etc. However, 47% and 81% of the leucoma and cataracts are blind. Now briefly discussed below. First, the corneal leukoplakia: the front of the eye is a layer of transparent cornea, it is easily injured or corneal ulcer infection due to inflammation, a major cause of corneal leukoplakia. Others such as infants and young children lack of vitamin A due to corneal softening infection, will also leave the corneal leukoplakia; severe corneal degeneration, can hinder the light into the eye, and even completely light can not penetrate the eye, resulting in blindness, these accounted for only Very few. Patients with corneal leukoplakia, if the normal light and color vision, indicating that the patient’s fundus (including the optic nerve and the retina) is healthy, only the corneal
