前言传统的老年性白内障诊断标准,以晶状体出现混浊、影响视力为依据,但为时已晚,因变性凝固的晶体蛋白不能恢复透明,只有等待内障成熟,手术摘除。尽管人工晶体植入对无晶体眼有所弥补,但仍有其缺点和并发症。因此,保持或延长老年人晶状体的透明性,是合理的设想。故有必要研究老年性白内障的更早期诊断体征,以便在晶状体发生混浊之前,进行早期防治。
Introduction The traditional diagnostic criteria for senile cataracts are based on the opacification of the lens and the visual acuity. However, it is too late. Crystalline proteins denatured by denaturation can not be restored to transparency. Only waiting for the cataract to mature and remove the surgically. Although intraocular lens implantation to make up for aphakia, but there are still shortcomings and complications. Therefore, to maintain or extend the transparency of the lens of the elderly, is a reasonable idea. It is therefore necessary to study earlier signs of diagnosis of senile cataracts in order to provide early control before opacification of the lens occurs.
