Abstract
This study was conducted to explore the prevalence and the associated factors of visual impairment and blindness among the elderly Taiwanese population. A nationwide population-based visual health care screening program of elderly people aged 65 years or older was conducted between 1 July 2002 and 31 December 2002 in Taiwan. Based on the same standardized protocol used by the Bureau of Health Promotion, Department of Health, and a stratified random sampling design, 3160 out of 5000 elderly subjects were selected by a two-stage visual care screening method. The overall response rate was 63.2%. The mean age of the elderly participants was 72.4 ± 5.1 years. The overall prevalence of glaucoma, corneal diseases, trauma, cataracts, myopic or diabetic retinopathy, and age-related macular degeneration among the elderly population was 2.1%, 6.3%, 0.9%, 60.2%, 7.5%, and 2.9%, respectively.
