Background/Aim: Refractive errors are abnormal visual conditions that are usually managed by spectacle correction, use of contact lenses or laser surgery. They are relatively common and should be corrected as soon as possible in children to enable them have adequate vision to live a normal active life without visually-induced limitations. With increasing westernization, the misconceptions illiterate and semi-literate parents had about use of glasses at an early age have been largely overcome and more young children are nowadays being brought to the hospital for visual problems and where refractive errors are implicated, having their parents actually purchase the spectacles and encourage their use. The aim of this study is to find out the types of refractive error that occur in children aged 1 - 18 years obtaining spectacle correction from the Nigerian National Petroleum Corporation (N.N.P.C.) Medical Services in Akpajo, Port Harcourt. This is for comparison with data obtained in other locations within the state, geographical region and worldwide for effective planning for future school health and prevention of blindness programmes in the state.

Methodology: This is a retrospective study in which data on refraction was obtained from the records of all children (aged 1 - 18 years) who were refracted during a period of one year (1st May, 2018 to 30th April, 2019) at the NNPC medical services facility. The children entitled to treatment in this facility are those of currently serving staff of the corporation. Relevant data such as age, sex and past ocular/family history were obtained from the electronic medical records. Other data included visual acuity, results of basic eye examinations; external ocular examination, funduscopy, slit lamp examination as well as the result of refraction. All the information was entered into a proforma specifically designed for this study and analysis was done using SPSS Version 20.

Results: One hundred and fifty one children were seen, sixty six males and eighty five females with an age range of 1 - 18 years. (mean age was 12.53 std = 3.18. The commonest refractive error encountered was hyperopic astigmatism, followed closely by myopic astigmatism. Hyperopia was uncommon and anisometropia was rare. Refractive error is commonest in the adolescent age group (13 - 18 years) and there is no significant relationship between type of refractive error and sex distribution of patients diagnosed with refractive error.
