作为发展中国家首位致盲原因的白内障,已日益引起人们的重视。在我国,近年对盲人或眼病的流行病学调查,已比较明确白内障盲人的比重。然而在自然人群中进行老年性白内障患病率的调查报告还是较少见。 As the first cause of cataract in developing countries, cataract has drawn increasing attention. In our country, the epidemiological investigation of blindness or eye disease in recent years has made it clear that the proportion of blind people with cataract has been relatively clear. However, the survey of the prevalence of senile cataract among the general population is still rare.
