To examine the association between self-rated vision and visual acuity by race.
Two thousand five hundred and twenty individuals, aged 65 to 84, including 666 Black participants and 1854 White participants from the Salisbury Eye Evaluation Study reported their self-rated vision score. Binocular visual acuity was assessed. Based on the level of visual acuity and the self-reported vision score, participants were placed into concordant and discrepant groups. Race specific Spearman correlation coefficients were calculated to estimate the strength of the association between the self-reported vision score and presenting binocular visual acuity. Age-adjusted multinomial logistic regression models were used to examine the characteristics associated with concordant and discrepant groups.
The Spearman correlation coefficient for the association between self-reported vision score and presenting visual acuity was -0.29 (95% confidence interval [CI], -0.24, -0.33) for White participants and -0.20 (95% CI, -0.12, -0.27) for Black participants. Being Black increased the odds more than two fold (odds ratio, 2.53; P=0.008) of being in the discrepant group that reported good vision but had a visual acuity worse than 20/40.
Black participants in the SEE population were more likely than White participants to report good vision in spite of having poor visual acuity. Given the racial discrepancies, self-reported vision status should be used cautiously in surveillance surveys especially when assessing racial disparities in vision.
