目的：研究四川省成年人视力损害主要原因的变化趋势，评价老龄化对其影响。方法：采用1987年和2006年四川省残疾人抽样调查数据。计算和比较VI主要病因的年龄调整患病率和各病因按年龄分层的患病率。结果：2006年，视网膜疾病增多，成为引起VI的第二大病因，而致盲沙眼明显减少。白内障和非沙眼角膜疾病是这两年VI的主要原因。我们发现年龄与VI的病因之间存在关联，其中年龄与白内障的相关性最强，而与其他原因的相关性相对较低。结论：在过去的20年里，VI的主要病因发生了巨大的变化，视网膜疾病显著增加，致盲沙眼减少。人口老龄化可能是VI变化趋势的一个重要因素。了解VI的患病率、主要原因和随时间的变化趋势有助于优先考虑和制定有效的干预策略并监测其影响。
AIM: To study the trends of major causes of visual impairment (VI) in adults in Sichuan, China and evaluate the effect of aging on the trends.METHODS: We used data from the National Sample Survey on Disabilities (NSSD) in Sichuan province conducted in 1987 and 2006. The age -adjusted prevalence of major causes of VI and the prevalence stratified by age in each cause were calculated and compared. The association between age and each cause of VI was also analyzed.RESULTS: Retinal disease increased and became the second leading cause of VI in 2006 while blinding trachoma decreased markedly. Cataract and non-trachomatous corneal diseases were among the leading causes of VI in both years. We found associations between age and causes of VI, with age showing the strongest association with cataract and relatively lower associations with other causes.CONCLUSION: In the last two decades, dramatic changes occurred in the major causes of VI with significantly increased retinal disease and decreased blinding trachoma. Aging of the population might be an important factor accounting for the changed trends of VI. Understanding the prevalence of VI, its major causes and trends over time can assist in prioritizing and developing effective interventional strategies and monitoring their impact.
