[Results of surgical treatment of alphabetical syndromes in esotropia. Apropos of 98 cases].

The authors report the results of 98 cases of esotropia treated by global surgery. They treated 72 "V" syndromes, 22 "A" syndromes and 4 cases without vertical incommitance but presenting visible hyperactivities of the oblique muscles. The alphabetical variations have been treated by weakening of the oblique muscles and sometimes have been treated by weakening of the oblique muscles and sometimes of the vertical recti which are part of the same torsional couple (inferior oblique - inferior rectus in the "V" syndrome, superior oblique - superior rectus in the "A" syndrome). Post-operative improvement has been obtained in 76% of the cases for the "V" syndrome and in 63% of the cases for the "A" syndrome. The surgery of the oblique muscle must be done according to the importance of the incommitance. The arc-technique permits these adjustments. Some pronounced "X" syndromes appear in the post-operative period. All anomalies found during motility examination should be surgically corrected.
