Detection of causes of low vision and blindness on the geriatric population.
Prospective non-interventional transversal case series of patients evaluated for first time at the ophthalmology department of the Hospital Nacional de Geriatria from September 2006 to April 2007. Screening included uncorrected and corrected Snellen Visual Acuity (VA), biomicroscopy, tonometry (Goldmann) and fundoscopy.
164 patients (326 eyes), mean age 75.9 +/- 8.44 years, 60.97% were females. 35.58% had low vision (53.5% refractive errors, 23.3% cataracts, 8.6% age macular degeneration (AMD)) and 14.11% legal blindness (47.8% refractive errors, 15.22% AMD, 13.04% cataracts).
Refractive errors and cataract are the leading causes of impaired vision in the geriatric population in Costa Rica.
