摘 要:目的应用减视年数(potentialyearsofvisionlost,PYVL)指标分析四川省因角膜病致盲的危害程度。方法采用《四川省1986年盲目和低视力流行病学调查》资料进行减视年数指标分析。结果四川省因角膜病致盲的减视年数率高于白内障致盲的减视年数率,不同于患病率的结果是后者高于前者。结论减视年数指标可以反映不同年龄视力损失程度的群体和个体差别。角膜病是防盲工作的重点。ObjectiveTo study the harmful degree of blindness caused by corneal diseases to the community and individuals in Sichuan Province by the index of potential years of vision lost(PYVL).MethodsBy a new index,PYVL,the data of blindness and low vision caused by corneal diseases in 1986 in Sichuan Province were analysed.ResultsThe PYVL rate of blindness caused by corneal diseases is higher than that of cataract,although cataract occupies the highest prevalence.ConclusionThe PYVL index can reveal the different effect of visual defect of different age groups of the community and individuals but prevalence can’t.The prevention and treatment of corneal disease is an important task in the prevention of blindness.
