A Comparison of the Effectiveness of Bilateral Resection to Unilateral Marginal Myotomy and Resection for Correcting Residual Esodeviations

Abstract

A review of patients with infantile esotropia that re-developed an esodeviation following a symmetrical recession of the medial recti was performed to determine the effectiveness of two methods for correcting residual esotropia.

Twelve patients were managed with bilateral lateral rectus resections and ten patients received a marginal myotomy-resection operation. All patients were followed for at least four years after the second operation. Bilateral lateral rectus resections were performed more frequently within the first year following bilateral medial rectus recessions. Marginal myotomy-resection operations were selected for recurrent esodeviations that occurred later in patients who had developed an ocular preference. Each operation had approximately an equal correction effect on the secondary esodeviation.
