General Anomalies Of Binocular Vision And Accommodation: Prevalence In The Population Of University Students

Purpose: To survey the prevalence of nonstrabismic accommodative andbinocular dysfunction in the population of university students.Methods: One hundred students were chosen randomly. Asymptom-questionnaire was taken which was related to their vision andseveral key tests were performed to diagnose any form of refractive,accommodative or binocular dysfunction.Results: Of the 100 subjects examined, 38 subjects (38%) had some form ofaccommodative or binocular dysfunction and required not just the correctionof the refractive error but related orthoptic treatment or other management foreach of the problems diagnosed. The frequency of binocular dysfuction was34.0%, and 4.0% for accommodative anomalies. Convergence insufficiency(18.0%) was more prevalent than convergence excess (7.0%). 13subjects(13%) were symptomatic without typical abnormal signs. Theirsymptom were attributed to inappropriate-corrected refractive error. 28asymptomatic subjects showed some abnormal signs. It meant that they couldstill compensate for their accommodative or binocular anomalies but requiredclose follow-up at optometric clinics.Conclusion: Non-strabismic binocular vision and accommodative disordersare prevalent conditions. Ophthalmologists and optometrists should keeptheir presence in mind and avoid the non-detection of these anomalies indaily optometric practice. Visual therapy and orthoptic treatment chose lie onexact diagnosis.
