The purpose of this study was to determine the prevalence and distribution of refractive error among schoolchildren in the Agona Swedru municipality of Central Region of Ghana.
This was a cross sectional school based study conducted with 637 randomly selected schoolchildren aged 11-18 years.
The prevalence of low vision (VA = 6/18 or worse in the better eye) was 2.5%.
Seventy-nine (85.9%) of those who failed the vision test and had refraction were found to have refractive errors representing the prevalence of 13.3%.
Out of the children with refractive errors, 30 (38.0%) had hyperopia, 10 (12.6%) had myopia while 39 (49.4%) had astigmatism.
The prevalence of hyperopia, myopia and astigmatism among the children was 5.0%, 1.7% and 6.6% respectively.
Uncorrected refractive error is a common cause of visual impairment among schoolchildren in the municipality suggesting the need for improved eye care services.
