Resumo

Purpose: To determine the prevalence and causes of visual impairment and blindness in adults aged 45 years and older from Parintins, Brazilian Amazon Region. Methods: A random cluster sampling method was used to identify subjects 45 years of age and older from urban and rural census sectors of Parintins city, Amazonas State, from March 2014 to May 2015. Participants underwent a detailed ocular examination, including presenting (PVA) and best corrected visual acuity (BCVA). The main cause of PVAResults: A total of 2384 subjects were enumerated and 2041 (85.6%) examined. The prevalence of presenting mild visual impairment - MiVI (<20/32 - >= 20/63) in the better-seeing eye was 17.0% {[}95% CI: 15.3-18.7%], and 8.5% {[}95% CI: 7.3-9.7%] with best correction. The prevalence of presenting moderate visual impairment - MVI (<20/63 - >= 20/200) was 18.4% {[}95% CI: 16.2-20.6%], and 6.9% {[}95% CI: 5.8-8.0%] with best correction. The prevalence of presenting bilateral VA <20/200 was 4.3% {[}95% CI: 3.6-5.0%], and 3.3% {[}95% CI: 2.5-4.0%] with best correction and increased with older age. Cataract (47.8%) and glaucoma (7.5%) were its main causes. In less severely affected eyes, uncorrected refractive errors (MVI: 42.6%; MiVI: 79.0%), cataract (MVI: 40.6%; MiVI: 13.7%) and pterygium (MVI: 7.6%; MiVI: 2.7%) were the main causes. Conclusions: Most cases of visual impairment in Parintins are either preventable or treatable, and public health initiatives should target cataract surgical services and refraction with spectacle provision.
