高龄老人2768例视力状况的临床分析

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2002年12月眼科会诊的2768人(5536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(fundus fluorein angiography，FFA)、吲哚青绿脉络膜血管造影(Indoeyanine green angiography，ICGA)、光学相干断层扫描(optical coherence tomography，OCT)等检查，找出病因。结果 患白内障者为5536眼(100．00％)，患老年性黄斑变性(aged-related macular degeneration，AMD)者为1982眼(35．72％)，剥脱综合症(pseudoexfoliatio nsyndrome，PXS)为1550眼(28．03％)，青光眼177眼(3．22％)，单纯性视神经萎缩133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。

Clinical analysis of visual acuity in 2768 venerable aged patients

Objective To investigate the main diseases affecting visual acuity in venerable aged patients.Methods 2768 patients(5536 eyes)over 80 years old were performed ocular examinations,patients whose vision less than 1.0 were carried out slit-lamp,direct or indirect ophthalmoscope,fundus fluorescein angiography(FFA),indocyanine green angiography(ICGA)or optical coherence tomography(OCT)examinations to find out the causes.Results There were 5536 eyes(100.00%)of which were caught cataract,1982 eyes(35.72%)of which were caught aged-related macular degeneration(AMD),1550 eyes(28.03%)of which were caught pseudoexfoliation syndrome(PXS),177 eyes(3.22%)were glaucoma,133 eyes(2.43%)were simple optic atrophy.The main diseases that affect vision were cataract,aged-related macular degeneration,glaucoma and optic atrophy.Conclusions Ocular diseases in venerable aged patients had great increase,while cataract and aged-related macular degeneration are the main disease affecting vision.
