Surgical treatment of residual esotropia.

Residual esotropia is a common problem following bilateral medial rectus (MR) recessions for esotropia. The patient was 30 years old men who underwent bilateral MR recession of both eyes in the childhood. Recession was repeated on the right eye few years after the first surgery, but residual esotropia progressed. Prior to our surgery residual angle of esotropia was 50PD degrees with restriction of abduction and elevation of the left eye. Sinechiolysis et myectomia of right MR and sinechiolysis and recession of left MR were performed using operating microskop. One week after surgery residual angle was 4 PD. Motility of both eyes was free except slight residual reduction of left eye elevation. During postoperative period of 2 years residual angle was not greater than 8 PD, with good motility of both eyes. We suggest that sinechiolysis and myectomia of MR together with recession of the prior operated muscle, when possible, can be a reasonable surgical option in the treatment of large-angle residual esotropia.
