Objective: To evaluate the ability of primary school teachers to perform simple vision screening on their school pupils, so as to determine if they can provide the first level of school vision screening services, and refer to the ophthalmologist for further evaluation when necessary. Methods: Using a multi-stage sampling technique, 130 teachers were randomly selected from 13 schools in Port Harcourt Local Government Area of Rivers State. They were trained for six hours at a skills acquisition workshop on vision disorders in children and vision screening using Snellen visual acuity charts. Subsequently, they screened 1,300 of their pupils, who were all re-screened by the research team. Results: One hundred and ten female (84.6%) and 20 male teachers (15.4%) participated in the study. Seventy (53.8%) were from public schools while 60 (46.2%) were from private schools. The sensitivity of the teachers' visual acuity test, compared to that of the research team, was 53.3%, with a high specificity of 94.6%. The positive and negative predictive values of the teachers' test were also high. The teachers' visual acuity measurements showed moderate agreement with that of the research team with a Kappa score of 0.604. Conclusion: The study concluded that trained primary school teachers can effectively perform vision screening in school children using Snellen visual acuity charts for early detection and treatment of vision disorders in school pupils.

“…In south -western Nigeria, Ajaiyeoba [10] documented a prevalence of 5.8% for uncorrected refractive errors. Faderin [12] also reported a prevalence of 7.3% for uncorrected refractive error in primary school children of south western Nigeria with hypermetropia predominating. The findings of this study were similar to ours.…”

“…Ajaiyeoba's result compared to ours is not unexpected as the South-Westerners are more highly educated than those in Bayelsa State where our study took place. The studies by Nkanga [6] in Enugu and Faderin [7] in Lagos, both in cosmopolitan cities, also observed high prevalence of refractive error ((7.4% and 7.3% respectively). The variation in the prevalence of refractive error in these regions may be related to ethnic differences and in the case of Lagos and Enugu, the large heterogeneous population.…”

“…In a study [6] on vision screening in primary school children in Enugu Nigeria, the prevalence of refractive error was 7.4%. Faderin [7] in her study on refractive error in pupils of Army children primary school in Lagos Nigeria found a prevalence of 7.3%. A similar study [8] on vision survey of school children in a rural community in south-east Nigeria observed a lower refractive error prevalence of 4.2%.…”

IntroductionVision screening study in primary school children has not been done in Bayelsa State. This study aims to screen for refractive error among primary school children in Bayelsa State and use the data to plan for school Eye Health Program.MethodsA cross sectional study on screening for refractive error in school children was carried out in Yenagoa Local Government Area of Bayelsa State in June 2009. A multistage sampling technique was used to select the study population (pupils aged between 5-15 years). Visual acuity (VA) for each eye, was assessed outside the classroom at a distance of 6 meters. Those with VA ≤6/9 were presented with a pinhole and the test repeated. Funduscopy was done inside a poorly lit classroom. An improvement of the VA with pinhole was considered refractive error. Data was analyzed with EPI INFO version 6.ResultsA total of 1,242 school children consisting of 658 females and 584 males were examined.About 97.7% of pupils had normal VA (VA of 6/6) while 56 eyes had VAs ≤ 6/9. Of these 56 eyes, the visual acuity in 49 eyes (87.5%) improved with pinhole. Twenty seven pupils had refractive error, giving a prevalence of 2.2%. Refractive error involved both eyes in 22 pupils (81.5%) and the 8-10 years age range had the highest proportion (40.7%) of cases of refractive error followed by the 9-13 year-old age range (37%).ConclusionThe prevalence of refractive error was 2.2% and most eyes (97.7%) had normal vision.
