Prevalence and causes of blindness and visual impairment in Kogi state, Nigeria-Findings from a Rapid assessment of avoidable blindness survey

To determine the prevalence and causes of blindness and visual impairment among adults in Kogi, Nigeria. A Rapid assessment of avoidable blindness (RAAB) protocol was used with additional tools measuring disability and household wealth to measure the prevalence of blindness and visual impairment (VI) and associations with sex, disability, wealth, cataract surgical coverage and its effectiveness. Age- and sex-adjusted all-cause prevalence of bilateral blindness was 3.6% (95%CI 3.0-4.2%), prevalence of blindness among people living with additional, non-visual disabilities was 38.3% (95% CI 29.0-48.6%) compared to 1.6% (95%CI 1.2-2.1%; [Formula: see text] = 771.9, p6/18) was seen in 61 eyes (52.6%) increasing to 71 (61.2%) eyes with best correction. Cost was identified as the main barrier to surgery. Findings suggest there exists inequalities in eye care with women, poorer people and people with disabilities having a lower Cataract Surgical Coverage, thereby, underscoring the importance of eye care programs to address these inequalities.
