Description

<p>[Purpose] Two years ago, we initiated a vision screening program for 5-year-old children and reported the usefulness of the program. The present study described our efforts to implement the screening program in 4-year-old children to determine the optimal age for performing pediatric vision screening.</p><p>[Subjects and Methods] The vision screening program targeted at 2,038 4-year-old children who were attending day-care centers or preschools in Niihama City between 2015 and 2016. Orthoptists from Sumitomo Besshi Hospital visited 37 day-care centers and preschools in Niihama City and performed eye examinations for near vision, refraction under a natural viewing condition using a binocular open-field autorefractometer, eye position, and binocular function if necessary.</p><p>[Results] At the primary screening, 2,016 (98.9%) of the 2,038 children could undergo the examinations and 275 (13.6%) children were suspected of having visual anomalies. Of 275, 231 (84.0%) children underwent a secondary screening by an ophthalmologist and 53 were diagnosed with amblyopia. Of 53, 31 were followed up at our hospital and their mean cycloplegic refraction, indicated by the spherical equivalent, was +2.78 ± 2.54 D. The mean duration required to achieve visual acuity of 1.0 in the affected eye was 172.75 ± 75.32 days.</p><p>[Conclusion] In the 31 children who were detected with amblyopia in the 4-year-old pediatric vision screening and were subsequently followed up at our hospital, those who had refractive error as the primary cause of the condition could achieve visual acuity of 1.0 in the amblyopic eye approximately within 6 months. Our results demonstrated that early detection of amblyopia and initiation of treatment before children reach school age could be effective and the pediatric vision screening appeared useful.</p>
