Alterations in its physiologyhave an important impact in health. It also affects psychological,social and productively, being a major cause of disability. It is anticipatedthat the number of visually impaired will increase significantly by 2020.Objective: To determine the causes of low visual acuity and visualimpairment in people attending to screening for blindness campaignin the Bolivian Foundation of Ophthalmology (FBO).Methods: Cross-sectional, descriptive and exploratory study. Studypopulation consists of people over 50 years old who visitedthe FBO for prevention campaign referring low vision. Variablesstudied were age, sex, best corrected visual acuity in both eyes,the presence of low visual acuity and causes of low visual acuity.Intervening variables included medical and surgical history. Datacollection techniques were direct observation and review of medicalrecords of patients.Results: We studied 260 subjects. We found visual acuity less than20/60 in 140 subjects, 71% of them were visually impaired. Themain causes of low visual acuity were cataracts, macular degenerationand glaucoma.Discussion and Conclusions:The prevalence of low visual acuityis superior to that found in other studies, due to the recruitmentmode of study population. The causes of low visual acuity coincidewith the statements by most authors. It is found that cataract is theleading cause of low visual acuity. -RESUMEN: Introducci車n: Se percibe el 80% de est赤mulos ambientales a trav谷sdel sistema visual, alteraciones en su funcionamiento repercuten enla salud, funcionamiento psicol車gico, social y productivo del afectado,siendo una causa importante de discapacidad.
