Abstract
Introduction: Learning problems influencing the social and psychological development of children may result from poor visual acuity (VA), insufficient amplitude of accommodation and receded near point of convergence (NPC). This study assessed Grade 4 and 5 academic achievement (< 50%, 51-69% and ≥ 70%) in relation to visual acuity, amplitude of accommodation and NPC. The study attempts to determine the association between these visual functions and academic performance. Methods: A cross-sectional study included a randomised sample of learners (n = 199) selected from five public schools in Bloemfontein. Information was obtained on each participant regarding history, visual acuity (distance and near), amplitude of accommodation and NPC (subjective and objective). Participant aggregates for the most recent school term and the grade average were compared to measures of these visual functions.Results: The children’s median age was 10.3 years (with range 8.7 to 12.7 years) and 53.8% were female. More than 50% of children were Sesotho-speaking. Complaints revealed by his-tory-taking were mostly headaches (57.8%) and eyestrain (58.3%). Regarding academic achievement, 18.6% of the learners were below average, 53.8% on average and 27.6% above average. Of the learners tested, 42.2% achieved a VA of 6/6 or better on both distance and near visual acuity. Amplitude of accommodation was less than the minimum requirements in 17.6% of participants. Approximately 30% of those below grade average did not meet the minimum requirements for amplitude of accommodation, compared to 13% of learners above grade average, which was statistically significant. More than 70% had a receded break point (> 5 cm) for NPC and 85.7% had a receded recovery point (> 7 cm).Conclusion: Of the three visual functions evaluated in this study, the only visual function associated with academic achievement was amplitude of accommodation. It would thus be recommended that learners are screened for optimal visual function earlier in life if especially the amplitude of accommodation is receded.
Highlights
Learning problems influencing the social and psychological development of children may result from poor visual acuity (VA), insufficient amplitude of accommodation and receded near point of convergence (NPC)
Learning problems that develop as a result of poor visual acuity, insufficient amplitude of accommodation and receded near point of convergence (NPC) play a vital role in the social, psychological and academic development of learners[1,2,3]
Academic performance at primary school level can affect self-esteem but may contribute to substantial levels of stress experienced by children and parents
Summary
Learning problems influencing the social and psychological development of children may result from poor visual acuity (VA), insufficient amplitude of accommodation and receded near point of convergence (NPC). Learning problems that develop as a result of poor visual acuity, insufficient amplitude of accommodation and receded near point of convergence (NPC) play a vital role in the social, psychological and academic development of learners[1,2,3]. In Grades 4 and 5, children start to write formal examinations requiring them to study larger amounts of work for longer periods of time. The results of these examinations would be more representative of true academic performance
