Influence of Binocular Visual Anomalies on Reading in First Grade School Children with High Visual Acuity.

The aim of this study was to describe the binocular visual status of first grade children with high binocular visual acuity. The results have shown that only 5.1% of children had normal binocular vision, 25.7% had only moderate and 67.9% had severe and moderate binocular anomalies. Significant differences were revealed between students with poor reading and with normal reading with respect to reduced convergence (P < 0.001), and mean scores of behavior symptom numbers, indicating the presence of binocular visual anomalies (P < 0.002).
