关于老年性白内障的患病率,我国已有许多文献报道。但这些报道多系眼科门诊及住院病人中老年性白内障所占的比例,或者盲和低视力调查中老年性白内障的患病率,真正以正常人群为基础的调查研究较少。而以正常视力人群调查者尚未见报道,但在临床实践中,观察到具有典型的起始于晶体赤道部楔形混浊的老年性白内障,视力仍保持正常者并非少见,本文以视力正常者为对象,于1986年,对北京海淀区部分大、中、小学的老师及科学研究单位的科学研究人员进行了老年性白内障发病情况的调查研究,
About the prevalence of senile cataracts, our country has many reports. However, these reports mostly account for the proportion of senile cataract in ophthalmology clinics and inpatients, or the prevalence of senile cataract in blind and low-vision surveys. There are few studies on the basis of normal population. However, there are no reports of people with normal eyesight. However, in clinical practice, it is not uncommon to observe cataract with typical wedge-shaped opacities starting from the equator of the crystalline lens and the eyesight remains normal. , In 1986, conducted a survey on the incidence of senile cataract in scientific research personnel from teachers of major, middle and primary schools and scientific research units in Haidian District, Beijing.
