PurposeTo investigate disparities in the prevalence and causes of visual impairment and blindness, cataract surgical coverage, and ocular findings in older adults from two Brazilian geo-socio-demographic areas, Sao Paulo and Parintins cities.MethodsData from two population-based studies including participants 50 years and older from the cities of Sao Paulo (Sao Paulo Eye Study - SPES, 2004) and Parintins (Brazilian Amazon Region Eye Survey - BARES, 2014) were aggregated.ResultsA total of 5318 participants (3677 from SPES,1641 from BARES) were included. The prevalence of severe visual impairment (SVI) and blindness were, respectively, 0.74% (0.46-1.02) and 0.77% (0.48-1.05) in SPES and 1.72% (1.09-2.35) and 3.44% (2.55-4.33) in BARES. SVI and blindness were associated with BARES study [OR = 2.27 (1.30-3.95), p = .004 - SVI] [OR:4.07 (2.51-6.60), p < .001- blindness], and older age [OR = 10.93 (4.20-28.45), p < .001 - SPES, OR = 17.96 (8.75-36.83), p < .001 - BARES] while higher education level was a protective factor [OR = 0.21 (0.05-0.95) - SPES, p = .042, OR = 0.21 (0.05-0.91), p = .037 - BARES]. Cataract was the main cause of bilateral severe visual impairment (25.93% in SPES and 64.29% in BARES) and bilateral blindness (21.43% in SPES and 35.71% in BARES). Cataract surgical coverage was significantly lower in BARES (36.32%) compared to SPES (57.75%).ConclusionThe prevalence of SVI and blindness was three times higher in older adults from the Brazilian Amazon compared to those living in Sao Paulo city, despite a 10-year interval between the two studies. These disparities should be mitigated by initiatives to promote access to eye care services targeting underprivileged and remote Brazilian areas.
