Abstract
To determine the prevalence and etiology of blindness and visual impairment as part of the Amazon Vision 2000 Project among Indians from Legal Amazon in Brazil. The Amazon Vision 2000 Project was established in 1997 to promote primary ocular health care to people from Legal Amazon. In this first phase of the Project, participants were 900 Indians from 3 different ethnic groups: Bororo (N=366), Xavante (N=334) and Karajá (N=200). Initial screening including visual acuity (VA), external appearance of the eyes and visual complaints was performed by health agents. Subjects with VA than 20/40 and/or visual complaints (N=190-21%) were submitted to ofthalmologic examination including slitlamp biomicroscopy, tonometry, cycloplegic refraction and dilated ocular fundus. Bilateral blindness (VA < 20/200 in the better eye) was found in 24 (2,7%) cases. The most frequent cause of bilateral blindness was cataract (N=19-79,2%). Corneal diseases (N=3-12,5%), glaucoma (N=1-4,2%) and diabetic retinopathy (N=1-4,2%) were present. Visual impairment (corrected VA 20/50-20/150 in the better eye was found in 18 (2%) cases. Cataract was also the most common cause of visual impairment (N=13-72,2%). Cataract surgery was performed in 31/37 patients. Prevalence of bilateral blindness and visual impairment among Brazilian Indigenous groups were, respectively, 2,9% and 2%. The most frequent etiological factor for vision loss was the presence of cataract.
