Patients and methods: This prospective study included 28 patients diagnosed with convergence excess esotropia who had worn their full cycloplegic refraction and/or bifocal glasses for at least 6 months and still had near-distance disparity esotropia. The patients were divided into 2 groups; Group I underwent combined bimedial rectus muscles resection 2.5 mm from the insertion end with recession based on near-angle esotropia according to current surgical tables with 1 mm add of recession for each muscle, while Group II underwent bimedial recession based on far angle combined with retroequatorial myopexy at 13–14 mm from insertion. A satisfactory result was defined as orthophoria or esotropia <10 prism diopters (∆) at near and distance with reduction of the near-distance disparity to <10 ∆. The patients were followed up for at least 2 years for stability of correction and late onset consecutive exotropia. Results: In Group I, all the patients had satisfactory alignments at near and far with residual near–far disparity ≤10 ∆, no cases of overcorrection at far was reported; while in Group II, all cases had orthophoria at far, but 4 cases (28.6%) showed near–far disparity >10 ∆. Conclusion: The technique of combined resection–recession is safe, easy and more effective in the treatment of near-distance disparity esotropia regardless of the level of accommodative convergence/accommodation ratio, with stability of results though longer follow-up period is still needed.
