晶体混浊及严重程度有一简单的临床分级方法。用一组标准照片与临床裂隙灯检查比较对核混浊的浓度分级。用后照法检查皮质混浊的范围,估计受累的部分,用裂隙光束来测量后囊下混浊的范围。这种方法对白内障的临床和流行病学的研究将会很有用。
There is a simple clinical classification of opacity and severity of the crystal. A set of standard photographs were compared with clinical slit lamp to classify the concentration of nuclear opacity. Cortical opacities were examined by post-mortem, the affected area was estimated, and the extent of posterior capsule opacities was measured with a slit beam. This method of cataract clinical and epidemiological studies will be very useful.
