Abstract

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.
