Causes and Pattern of Eye Diseases in Children Attending the Paediatric Eye Unit of Ahmadu Bello University Teaching Hospital, Shika, Zaria

Abstract

Aim: The purpose was to determine the causes and pattern of eye diseases in children 0-15 years of age who attended the paediatric unit of the Ophthalmology department Ahmadu Bello University Teaching Hospital Shika, Zaria with a view of obtaining data for planning of children eye care. Methods: This was a descriptive cross-sectional study. All children that met the inclusion criteria were recruited. Subjects had visual acuity assessments as appropriate for age. Anterior segment examination was done using a loupe or slit lamp biomicroscope as appropriate while posterior segment was examined by direct ophthalmoscopy. Manual refraction was done using streak retinoscope (cycloplegic refraction when required). Results: A total of 12,516 patients attended the Ophthalmology out-patient clinic of the hospital during the 30- month study period (May 2014- October 2016), 1,760 old and new patients (14.1%) were patients 0-15 years of age (study population). A total of 448 children were recruited for the study. The male to female ratio M:F was 1.3:1. Allergic conjunctivitis 181 (40.4%), refractive error 42 (9.4%) and infective conjunctivitis 39 (8.7%) were the most common ocular disorders seen. The prevalence of visual impairment was 34.4%. Trauma was the most common cause of uniocular visual impairment. The proportion of blind eyes was 3.1% (n=12). Conclusions: Majority of the ocular disorders seen among the children were treatable causes of visual impairment. Public health education is necessary to create awareness on the causes of blindness. However, there was no statistically significant difference in the ocular disorders with respect to age and gender of the children.
