Abstract
|
|
|
Vision training was conducted for a 10-year-old girl who have exophoria with convergence insufficiency. Prior to the start of vision training, the patient’s exodeviation was 8.67±1.15 ? at distance and 26.67±2.89 ? at near and positive fusional convergence was 8/10/4 ? at distance and 20/25/16 ? at near. The gradient AC/A ratio was measured as 1.8:1. After the vision training, distant exodeviation was 2.67±1.15 ?, and near exodeviation was 11.33±1.15 ? and the positive fusional vergence was 18/25/20 ? at distance and 30/35/25 ? at near.
After vision training, both distance and near exodeviation was decreased and the positive fusional vergence value was increased.
