Paediatric Refractive Errors in an Eye Clinic in Osogbo, Nigeria
This study set out to determine the pattern of refractive errors in children attending an eye clinic in South West Nigeria.
The age range of subjects was between 3 and 16 years with mean age = 11.7 and SD = 0.51; with males making up 33.9%.
The commonest presenting complaint was blurring of distant vision (40%), presenting visual acuity 6/9 (33.9%), normal vision constituted >75.0%, visual impairment20% and low vision 23.3%.
Low grade spherical and cylindrical errors occurred most frequently (35.6% and 59.9% respectively). Regular astigmatism was significantly more common.
The commonest diagnosis was simple myopic astigmatism (41.1%). Four cases of strabismus were seen.
Simple spherical and cylindrical errors were the commonest types of refractive errors seen. Visual impairment and low vision occurred and could be a cause of absenteeism from school.
Low-cost spectacle production or dispensing unit and health education are advocated for the prevention of visual impairment in a hospital set-up.
