Surgical Management of Convergence Excess Esotropia

Abstract

Propose:The purpose of this study was to evaluate retro-equatorial myopexy (faden operation) of medial rectus muscles for the treatment of near-distance disparity esotropia.Patients & Methods: This study included 14 patients with convergence excess esotropia not responding to bifocal glasses. All patients underwent bimedial recession based on far angle combined with retro-equatorial myopexy at 12-14mm from insertion (faden operation). A satisfactory result was defined as orthophoria or esotropia less than 10 prism diopters (Δ) at near and distance with reduction of the near-distance disparity to less than 10 Δ. All patients were followed up for 1 year in average and 6 months at least for stability of correction and onset of consecutive exotropia Results: 1 case (7%) had residual esotropia at far, 2 cases (14%) had residual near-far disparity and no cases had consecutive exotropia;Conclusion: Faden operation is effective in management of convergence excess esotropia. However, it is quite difficult technique.Larger sample size and longer follow-up periods are still needed.
