白内障是人类致盲的重要原因之一。掌握其发展规律,对于揭示白内障发生机理和选择有效治疗方法都具有重要的实用价值。目前,临床上主要使用裂隙灯显微镜进行晶体形态学的检查。判定晶体混浊的形态特点常受医生主观印象的干扰,并难以对同一病人做长期追踪观察和比较。实验室研究也难以将生化等方面的数据资料与白内障形态改变做相应的评价。因此,研制客观反映晶体透明度的现代方法势在必行。本文对近年国外眼科学者创造的几种检查方法简单介绍如下: 一、离体晶体彩色摄影分类法Chylack(1978)报告,将冷冻术摘出的完整 Cataracts are one of the major causes of human blindness. To master the law of its development has important practical value for revealing the mechanism of cataract and choosing effective treatment methods. At present, the clinical use of slit lamp microscope crystal morphology examination. It is often disturbed by the doctor’s subjective impression to determine the morphological characteristics of crystal opacity, and it is difficult to make long-term follow-up observation and comparison on the same patient. Laboratory research is also difficult to biochemical and other aspects of data and cataract morphological changes do the corresponding evaluation. Therefore, it is imperative to develop a modern method of objectively reflecting the transparency of the crystal. In this paper, the foreign ophthalmologists in recent years to create several inspection methods are briefly described as follows: First, the in vitro crystal color photography classification Chylack (1978) report, frozen extracted complete
