Abstract: | A retrospective study of 49 patients (22 males and 27 females) has been completed. The mean age of the group was 20.1 years. Diplopia, headaches, asthenopia and blur as a result of binocular visual dysfunction were the most frequently reported symptoms. Sixty-five per cent of the group were found to have either intermittent or constant deviations of the eyes. Over the mean course of treatment of 7.6 weeks, the distance and near angles of deviation, the positive vergences at distance and near, the near point of convergence and the binocular amplitude of accommodation were found to have changed significantly. Constant deviations were strongly related to longer necessary treatment durations. Further results of the treatment are presented and the implications of this data with regard to the treatment of these patients is briefly discussed. |
