  • Title: Comparison of the Efficacy of Medial Rectus Recession and Lateral Rectus Resection for Treatment of Divergence Insufficiency.
    Author: Breidenstein BG, Robbins SL, Granet DB, Acera EC.
    Journal: J Pediatr Ophthalmol Strabismus; 2015; 52(3):173-6. PubMed ID: 26053209.
    Abstract:
    PURPOSE: Surgical approaches for divergence insufficiency esotropia include medial rectus recession and lateral rectus resection. A retrospective chart review compared the efficacy of each. METHODS: Eighteen patients older than 50 years with divergence insufficiency esotropia who were operated on between 2005 and 2012 by two surgeons were reviewed. RESULTS: Nine patients underwent medial rectus recession and nine underwent lateral rectus resection. The average distance esotropia decreased from 19.75 to 3.2 prism diopters in the medial rectus recession group (P = .001) and from 17.7 to 2.6 prism diopters in the lateral rectus resection group (P = .0002). The disparity between distance and near alignment decreased from 7.3 to 3.4 in the medial rectus recession group (P = .019) and from 9 to 5.4 prism diopters in the lateral rectus resection group (P = .004). CONCLUSIONS: Both medial rectus recession and lateral rectus resection are effective treatment for divergence insufficiency, with both decreasing distance-near disparity.
