Surgical treatment options in cyclotropia.

We report our experience with a procedure involving the transposition and realignment of the vertical recti muscles, in two cases. In the first case, 11 degrees of unilateral excyclotropia was corrected by a one muscle width nasal transposition of the ipsilateral inferior rectus muscle. In the second case, excyclotropia was created in both eyes by a one-half muscle width nasal transposition of both superior recti, and, in a second operation, reversed by a horizontal realignment of these muscles. We found this procedure to be useful in the treatment of both incyclo- and excyclotropia.
