Abstract:
For undercorrected esotropia after bilateral medial rectus(MR) recession, we performed unilateral or bilateral MR rerecession, unilateral rerecession or marginal myotomy of the recessed medial rectus muscle combined with lateral rectus(LR) resection, or unilateral LR resection. The correction of deviation was 15 delta in unilateral 2.0mm MR rerecession. Bilateral 2.0mm MR rerecession corrected 20 to 25 delta of esodeviation, but undercorrection was noted in one case. With unilateral 2.0mm rerecession or marginal myotomy of the recessed medial rectus muscle combined with 5.5mm or 8.0mm LR resection, the correction of deviation was 26 to 29 delta, and there was no under- or overcorrection. The corrective effect of this procedure was therefore greater and more stable than that of bilateral 2.0mm MR rerecession. Unilateral 8.0mm LR resection performed 3 months after bilateral MR recession showed correction of 15 delta, whereas the same procedure performed 3 weeks after bilateral MR rerecession showed correction of 24 delta. Unilateral LR resection procedure seems to be more efficacious for residual esotropia if performed as soos as possible within 3 months after sufficient bilateral MR recession or rerecession.
