Prevalence of refractive error among Dongarias and use of Folding Phoropter Report # 13

Purpose To evaluate the prevalence of uncorrected refractive error (URE) among Dongarias-a particularly vulnerable tribal group in Rayagada, Odisha, India and evaluate if folding phoropter (FoFo) can help achieve on-site correction of URE. Methods This was a cross-sectional study. FoFo was used for...

Description
Summary:Purpose To evaluate the prevalence of uncorrected refractive error (URE) among Dongarias-a particularly vulnerable tribal group in Rayagada, Odisha, India and evaluate if folding phoropter (FoFo) can help achieve on-site correction of URE. Methods This was a cross-sectional study. FoFo was used for people with URE. Spherical equivalent (SE) spectacles based on the FoFo refraction were dispensed when distance visual acuity improved to > 6/12. Others were referred to fixed eye centres. Multivariable logistic regression evaluated the relationship of URE with sociodemographic characters and factors predicting acceptance of FoFo. Results In the study, 7.5% (95% confidence interval [CI]:7-8) people had URE, and included 4% with severe vision impairment and 36% with moderate visual impairment. URE was less common in children. Simple hyperopia was more common in females (25.3% vs 19.3%); compound myopic astigmatism was more common in males (27.4% vs 20.2%). People older than 50 years (p
