“…Previous investigations report associations between cataract and postural balance, fear of falls and quality of life 29,30 . However, the studies cited did not address other dimensions of the phenomenon (falls) in the population and were limited to the description of socio-demographic characteristics 31,32 . Likewise, few multidimensional studies are found in the international literature addressing the relationship between visual impairment and falls 18 .…”

The aim of the present study was to evaluate factors associated with falls in community-dwelling older adults diagnosed with cataracts. An analytical, cross-sectional study was conducted with a sample of community-dwelling older adults residing in the Federal District of Brazil. Interviews and assessment tools were administered, such as the Timed Up and Go test, Short Physical Performance Battery (SPPB), Biodex Balance System, Katz Index, Lawton Scale, Minnesota Leisure Time Physical Activity Questionnaire and Mini Mental State Examination. Statistical analysis involved binary logistic regression. One hundred forty-two older adults (85 with cataracts) participated in the study (mean age: 69.39 ± 5.67 years). Falls were associated with the female sex (OR: 4.45) and sub-maximum score on the SPPB (OR: 3.53) among patients with cataracts, whereas multimorbidity (OR: 5.10) was the risk factor risk for older adults without cataracts. The data suggest different risk factors for falls among older adults diagnosed with cataracts.

“…Cataracts are the leading cause of blindness, and account for approximately 51% of cases [ 1 ]. The prevalence of cataracts appears to be increasing with recent reports ranging from approximately 4.9% in Brazil to as high as 23% in Indonesia and Sweden [ 2 – 4 ]. It is expected that age-related cataracts will continue to be an important global health issue due to increasing life expectancy [ 5 ].…”

The aim of this study was to investigate the association of central and abdominal obesity with the prevalence of cataracts in a middle-aged Korean population. This retrospective cross-sectional study was based on the data collected from the Korea National Health and Nutrition Examination Survey 2008–2009, in which 4,914 subjects were examined. Ophthalmological examinations were performed to determine the presence of a nuclear, cortical, or posterior subcapsular cataract. Both general obesity (a body mass index ≥25 kg/m2) and abdominal obesity (a waist circumference ≥90 cm for men and ≥80 cm for women) were significantly associated with the occurrence of cataracts among middle-aged women [adjusted odds ratio (aOR), 1.32; 95% confidence interval (CI), 1.03–1.69; and aOR, 1.40; 95% CI, 1.06–1.85, respectively], while abdominal obesity was significantly inversely associated with the occurrence of cataracts among middle-aged men (aOR, 0.76; 95% CI, 0.58–1.01; and aOR, 0.66; 95% CI, 0.49–0.89, respectively). We report a difference in the association between obesity and the prevalence of cataracts based on gender.

“…Indirect interstudy comparisons pointed to higher disease rates in indigenous peoples compared with nonindigenous populations, including in Nigeria (glaucoma, 6.9% vs 5.0%), the United States (cataract, 39.6% vs 17.2%; AMD, 35.2% vs 6.5%; and glaucoma, 12.9% vs 2.1%), Brazil (cataract, 13.7% and 24.5% vs 4.9%; glaucoma, 8.1% vs 3.4%; and pterygium, 5.0%-36.6% vs 8.1%), and Taiwan (pterygium, 44.1% vs 25.2%) . Some interstudy comparisons suggest a higher disease prevalence in nonindigenous populations, including in the United States (diabetic retinopathy, 20.1% vs 35.1%), Taiwan (AMD, 5.2% vs 11.1%), and Australia (glaucoma, 1.1% vs 3.0%; myopia, 10.1% vs 17%).…”

Prevalence and Causes of Visual Loss Among the Indigenous Peoples of the World

IMPORTANCEStudies have documented a higher disease burden in indigenous compared with nonindigenous populations, but no global data on the epidemiology of visual loss in indigenous peoples are available. A systematic review of literature on visual loss in the world's indigenous populations could identify major gaps and inform interventions to reduce their burden of visual loss.OBJECTIVE To conduct a systematic review on the prevalence and causes of visual loss among the world's indigenous populations.EVIDENCE REVIEW A search of databases and alternative sources identified literature on the prevalence and causes of visual loss (visual impairment and blindness) and eye diseases in indigenous populations. Studies from January 1, 1990, through August 1, 2017, that included clinical eye examinations of indigenous participants and, where possible, compared findings with those of nonindigenous populations were included. Methodologic quality of studies was evaluated to reveal gaps in the literature.FINDINGS Limited data were available worldwide. A total of 85 articles described 64 unique studies from 24 countries that examined 79 598 unique indigenous participants. Nineteen studies reported comparator data on 42 085 nonindigenous individuals. The prevalence of visual loss was reported in 13 countries, with visual impairment ranging from 0.6% in indigenous Australian children to 48.5% in native Tibetans 50 years or older. Uncorrected refractive error was the main cause of visual impairment (21.0%-65.1%) in 5 of 6 studies that measured presenting visual acuity. Cataract was the main cause of visual impairment in all 6 studies measuring best-corrected acuity (25.4%-72.2%). Cataract was the leading cause of blindness in 13 studies (32.0%-79.2%), followed by uncorrected refractive error in 2 studies (33.0% and 35.8%).CONCLUSIONS AND RELEVANCE Most countries with indigenous peoples do not have data on the burden of visual loss in these populations. Although existing studies vary in methodologic quality and reliability, they suggest that most visual loss in indigenous populations is avoidable. Improvements in quality and frequency of research into the eye health of indigenous communities appear to be required, and coordinated eye care programs should be implemented to specifically target the indigenous peoples of the world.
