目的 探讨影响高龄老年人视力的主要致病因素。方法 对我院南楼 1999年 1月至2 0 0 2年 12月眼科会诊的 2 768人 ( 5 5 3 6眼 ) 80岁以上老年人行眼科常规查体 ,对矫正视力低于 1 0者行视野、眼底荧光血管造影 (fundusfluoresceinangiography ,FFA)、吲哚青绿脉络膜血管造影 (In docyaninegreenangiography ,ICGA )、光学相干断层扫描 (opticalcoherencetomography ,OCT)等检查 ,找出病因。结果 患白内障者为 5 5 3 6眼 ( 10 0 0 0 % ) ,患老年性黄斑变性 (aged -relatedmaculardegeneration ,AMD )者为 1982眼 ( 3 5 72 % ) ,剥脱综合症 ( pseudoexfoliationsyndrome ,PXS)为15 5 0眼 ( 2 8 0 3 % ) ,青光眼 177眼 ( 3 2 2 % ) ,单纯性视神经萎缩 13 3眼 ( 2 43 % )。影响视力的主要原因依次是白内障、老年性黄斑变性、青光眼、视神经萎缩。结论 高龄老年人眼部疾病明显增多 ,白内障和老年性黄斑变性是影响视力的主要疾病
Objective To explore the main pathogenic factors that affect the vision of the elderly. Methods A total of 2 768 (566 eyes) aged 80 years or older in our hospital from January 1999 to December 2002 were enrolled in routine ophthalmologic examination. The corrected visual acuity was less than 10 Visual field, fundus fluorescein angiography (FFA), indocyanine green color angiography (ICGA), optical coherence tomography (OCT) and other tests to find out the cause. Results Fifty-three (63) eyes (100%) with cataract and 1982 (3572%) with age-related macular degeneration (AMD) had pseudoexfoliationsyndrome (PXS) Fifty-five eyes (2880%), 177 eyes (322%) of glaucoma, and 13 eyes (243%) of pure optic atrophy. The main causes of visual acuity were cataract, age-related macular degeneration, glaucoma and optic atrophy. Conclusion Ocular diseases in the elderly are obviously increased. Cataracts and age-related macular degeneration are the major diseases affecting vision
