Diagnosis and surgical options in superior oblique surgery.

The surgical treatment of superior oblique paresis is most gratifying to the patient and to the surgeon. Whereas the large range of vertical fusion may make it difficult to bring out the total deviation, this same fusion is the surgeon's best ally postoperatively. In addition, while there are multiple choice as to which muscle or muscles to operate upon, the great advantages of the tucking operation on the superior oblique are (1) it practically always straightens the head, (2) it greatly reduces the hyperdeviation, and (3) it has no effect on the width of the lid fissures.
