Clinical practice patterns for assessing children with learning difficulties: survey of eye health care professionals

Clinical relevance: Understanding what aspects of vision or binocular vision may affect learning, and how these are assessed, is important for the eye health care professional assessing children with learning difficulties. It is vital that visual dysfunction is identified or excluded in these patients to ensure targeted and timely intervention.Background: The aim of this study was to investigate similarities and differences between eye care professionals in the knowledge, attitudes and practice patterns, when evaluating children with learning difficulties.Methods: This study was a cross-occupational, cross-sectional, predominantly quantitative internet-based survey. Ophthalmologists, optometrists, and orthoptists working in Australia were eligible to participate. A questionnaire comprising of 31 multiple-choice questions with up to 19 additional branching questions was distributed using REDCap in September 2022.Results: A total of 130 responses were analysed (6 ophthalmologists, 84 orthoptists and 40 optometrists of whom 9 were practicing behavioural vision care). Most respondents assessed distance visual acuity (95%), near stereoacuity (85%), presence of strabismus (88%) and ocular movements (91%). Near vision was assessed less often (65%). Optometrists were most likely to measure colour vision (p < 0.002), accommodation and undertake a subjective refraction (each p < 0.001). Ophthalmologists were least likely to measure convergence (p = 0.041) but more likely to undertake a cycloplegic refraction (p = 0.044). More optometrists practicing behavioural vision care reported testing binocular vision (p = 0.026), fusional vergence (p < 0.001), saccades (p = 0.066), and smooth pursuit (p = 0.050) than other professions. There was a positive correlation between frequency and confidence level when assessing children with learning difficulties (rho = 0.64). Respondents referred to paediatricians (39%), speech pathologists (30%), educational psychologists (29%) and general practitioners (29%).Conclusion: Despite similarities across occupations, there were differences in testing the vision and binocular functions of children with learning difficulties. Future research should aim to establish minimum standards for assessing this patient cohort to ensure consistent and relevant assessment.

Automated summary

Understanding the impact of vision and binocular vision on learning, as well as how to assess these aspects, is crucial for eye health care professionals evaluating children with learning difficulties. This study aimed to investigate the similarities and differences in knowledge, attitudes, and practice patterns among eye care professionals when evaluating such children. The results indicated variations in testing the vision and binocular functions of children with learning difficulties across different professions.
