Abstract: Purpose: To discuss the prevalence and associated factors related to visual impairment and blindness amongst the elderly agricultural and fishing population. Methods: A total of 6542 healthy elderly adults voluntarily admitted to a teaching hospital for a physical check-up and eye disease in Taipei, Taiwan. Results: The overall prevalence of visual disability (the better eye visual acuity <0.5) was 13.2%, including 12.8% of visual impairment and 0.4% of blindness. From the logistic regression, the significantly independent factors of visual disability (visual impairment plus blindness) were sex (male vs. female, OR=0.68, 95%CI: 0.55-0.85), age (65-74 yrs vs. 60-64 yrs, OR=1.49, 95%CI: 1.18-1.89, 75-84 yrs vs. 60-64 yrs, OR=2.77, 95%CI: 2.11-3.65, ³85 yrs vs. 65-69 yrs, OR=4.76, 95%CI: 3.55-6.39), glaucoma (OR=1.51, 95%CI: 1.02-2.23), corneal diseases (OR=2.27, 95%CI: 1.69-3.05), myopic or diabetic retinopathy (OR=1.77, 95%CI: 1.29-2.42), age-related macular degeneration (OR=3.78, 95%CI: 2.36-6.05), and cataract (OR=3.22, 95%CI: 2.50-4.16). Conclusions: Our results revealed that visual impairment and blindness are important visual health problems in elderly agricultural and fishing population. Age-related macular degeneration, cataracts, corneal diseases, myopic or diabetic retinopathy, glaucoma, female, and increased age were the leading causes for the visual disability. Further organized preventive strategies to eye care are recommended in this sub-population.
