“…The leading causes of preventable visual impairment in the studied area were cataracts (10.2%), refractive errors (8.4%), glaucoma (7.0%), age-related macular degeneration (4.1%), and diabetic retinopathy (2.1%). This is in consonance with the study carried out by Hudu et al in Jos North Local Government Area of Plateau State, Nigeria, [37], Nigeria Army Eye Centre, Bonny Cantonment Lagos, Nigeria, [38] as well as in other countries [39][40][41][42].…”

Aim: Visual impairment is a public health problem globally. This study aimed to determine the prevalence and pattern of visual impairment among adult population in Mangu Local Government Area (L.G.A), Plateau State, Nigeria. Study Design: A population-based descriptive cross-sectional survey of 802 adult population aged 18 years and above was conducted in Mangu L.G.A, Plateau State, Nigeria using a multi-stage cluster random sampling design. Methodology: Subjects were evaluated using a magnifying loupe, Snellen E chart, direct ophthalmoscope and torchlight. Vision status was defined using World Health Organization categories of visual impairment based on presenting visual acuity (VA). Results: Out of a total of 960 respondents enumerated for the study, 802 (83.5%) adults participated. Prevalence of blindness (presenting VA of less than 3/60 in the better eye) was 8.1%; prevalence of low vision (presenting VA of at least 3/60 but less than 6/18 in the better eye) was 27.6%; prevalence of overall visual impairment (presenting VA less than 6/18 in the better eye) was 35.7%. Prevalence of visual impairment was higher in males (40.8%) than in females (34.9%), although not statistically significant (p=0.098). Prevalence of blindness and impaired vision increased significantly with increasing age, from 21.7% at 20 - 39 years to 83.6% among those aged ≥80 years (P < 0.001). Conclusion: Much can be done by individuals, governments and non-governmental organizations to reduce so much blindness and vision loss through cost-effective interventions such as wears of sunglasses and other preventive measures to prevent ultraviolet radiation effect on their eyes.

Review of the burden of vision impairment and blindness and ocular disease occurrence in Indigenous Peoples of the Americas. We systematically reviewed findings of the frequency of vision impairment and blindness and/or frequency of ocular findings in Indigenous groups. The database search yielded 2829 citations, of which 2747 were excluded. We screened the full texts of 82 records for relevance and excluded 16. The remaining 66 articles were examined thoroughly, and 25 presented sufficient data to be included. Another 7 articles derived from references were included, summing a total of 32 studies selected. When considering adults over 40 years old, the highest frequencies of vision impairment and blindness in Indigenous Peoples varied from 11.1% in high-income North America to 28.5% in tropical Latin America, whose rates are considerably higher than those in the general population. Most of the ocular diseases reported were preventable and/or treatable, so blindness prevention programs should focus on accessibility to eye examinations, cataract surgeries, control of infectious diseases, and spectacles distribution. Finally, we recommend actions in six areas of attention towards improving the eye health in Indigenous Peoples: access and integration of eye services with primary care; telemedicine; customized propaedeutics; education on eye health; and quality of data.
