EFFECT OF POSTERIOR FIXATION SUTURES ON THE ACCOMMODATIVE ELEMENT OF PARTIALLY ACCOMMODATIVE STRABISMUS

In a prospective study, we investigated the effect of posterior fixati on sutures on the accommodative element of partially accommodative str abismus. Twenty patients were included in the study. Recession of one or both medial rectus muscles combined with bilateral posterior fixati on sutures was performed on each patient. The results showed that this combined operation had a greater effect on the angle without glasses at both distance and near fixation, but not enough to eliminate the an gle without glasses in all the cases. The results in patients with con vergence excess are not satisfactory, as far as the reduction of the a ngle without glasses is concerned. In patients without convergence exc ess, this operation is effective in satisfactorily reducing the squint without glasses when the difference of the angle with and without gla sses does not exceed 15 Delta.
