摘要

目的:調查台北市65歲(含)以上老人視力障礙之 盛行率及其原因。方法：本研究以台北市大同、中山區 65歲(含)以上老人為篩檢對象,進行視力檢查。如果 表現視力低於0.5 ，則轉介做進一步眼科檢查。視力障礙 定義為優眼最佳矯正視力低於0.5。結果:共計有367位 老人接受視力篩檢。受檢者初步篩檢雙眼表現視力均低 於0.5的比例為7.9%。受檢者複檢視力障礙之比率為 1.9%。本研究老人視力障礙最常見的原因是白內障及其司關疾病(51.3%) ,其次是視網膜及其相關疾病 (33.3%)。其中視網膜及其相關疾病與老人視力障礙有極明顯的相關性。結論:白內障及其相關疾病是台北市的 歲(含)以上老人視力障礙最常見的原因,其次是視網膜 及其相關疾病。而視網膜及其相關疾病與視力障礙有極明顯的相關性。

Objective: This study was conducted to investigate the prevalence and associated factors of
visual impairment among people aged 65 years or older in Taipei, Taiwan. Methods: This was a population-based, cross-sectional study. People aged 65 years or alder were enrolled for interviews and ophthalmic examinations in a visual healthcare survey in 2 districts of Taipei. The ophthalmic examinations included visual acuity testing, and slit-lamp and dilated retinal examinations for those presenting with visual acuity worse than 6/12. Visual impairment was defined as the best-corrected acuity of worse than 6/12 in the better-seeing eye. Results: Three hundred and sixty-seven elderly people were included in this study.
The proportion of overall bilateral presenting acuity of worse than 6/12 was 7.9 %. Alter referral, we estimated the proportion of visual impairment among the elderly in Taipei to be 1.9%. Cataract-related disease was the most-frequent factor (51.3%) associated with visual impairment, followed by retinopathy-related disease with/without macular edema (33.3%). Multiple logistic regression revealed that retinopathy with/without macular edema was the most significantly associated facto r correlated with visual impairment among the elderly (odds ratio = 49.82, 95% confidence interval: 4.58-542.19). Conclusions: Although cataracts were the most frequent factor in visual impairment, we found that retinopathy with/without macular elderly was the most significantly associated factor related to visual impairment among elderly people in Taipei.
