Prevalence of refractive error among Dongarias and use of Folding Phoropter (FoFo) as a field device enabling implementation research in this indigenous community. Tribal Odisha Eye Disease Study (TOES) Report # 13.

ABSTRACT:

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
