The purpose of this study was to determine the magnitude and pattern of significant refractive errors (visual acuity less than 6/18) among primary school children.
This was a cross sectional school based study conducted with 1439 primary school pupils aged 12 to 15 years.
The study found that 5.2% (75) pupils had refractive errors and the rest 94.4% (1358) had normal vision.
The prevalence of refractive errors was 5.2%.
Hypermetropia was the most prevalent refractive error at 62.7% (47) followed by myopia 32.0% (24) and astigmatism at 5.30%.
Of the 75 pupils with refractive errors and in need of spectacles, 66 (88%) had no spectacles.
Nine pupils (12%) said they had been prescribed spectacles previously but only one (13%) was noted to be wearing spectacles at the time of examination.
The overall prevalence of significant refractive errors in pupils in Makueni’s Kilungu division was 5.2% suggesting the need for regular school screening programme.
