Abstract

Background: Much of the vision loss from age-related eye disease can be prevented. The purpose of this study is to determine the prevalence of preventable causes of low vision.
Materials and Methods: In this study, files of 204 patients were evaluated. Low vision was defined as best-corrected visual acuity in the better eye between 20/70 to 20/200. Diagnosis of anterior and posterior segment disease was based on the eye examination that performed with Topcon slit-lamp biomicroscope and direct and indirect ophthalmoscope examination.
Results: The prevalence of preventable causes of low was respectively: diabetic retinopathy, in 33 patients (16.18%), glaucoma in 6 patients (2.94%), and amblyopia in 2 patients (1%).
Conclusions: The majority of cases have treatable and/or preventable causes; reduction of low vision or blindness can be achieved by appropriate screening strategies.
