白内障在盲人中占很大的比例,成为当今眼科研究的重要课题之一。然而,限制白内障临床研究的一个重要因素是对白内障或晶体混浊的观察缺乏一个相同的可重复的定义及分类系统。近年来,有学者提出了晶体混浊的分类方法,并证实标准照片与临床分类之间有极佳的重复性。针对观察者之间的一致性,我们在门诊工作中,作了初步的尝试。 Cataracts account for a large proportion of blind people and become one of the most important topics in ophthalmic research. However, an important factor limiting the clinical study of cataracts is the lack of an identical, reproducible definition and classification system for the observation of cataract or crystal opacity. In recent years, some scholars have proposed a classification method of crystal opacity and confirmed that there is excellent repeatability between the standard photograph and the clinical classification. In view of the consistency between the observers, we made preliminary attempts in the clinic.
