Abstract:
Sixty cases of intermittent exotropia were studied to compare the outcome of those patients treated medically with the outcome of those patients treated surgically. Below 30 prism diopters of intermittent exotropia, there is a high functional cure rate in both groups. Preoperative orthoptics did not lead to a surgical overcorrection. And finally, central fusion is not essential for a clinical cure.
