Abstract

Purpose: The purpose of this study was to evaluate combined recession and resection of medial rectus muscles for the treatment of near-distance disparity esotropia. Background: Convergence excess esotropia is defined as esotropia that is greater for near fixation than for distance. An acceptable definition of convergence excess esotropia would be a convergent squint, which is greater for near fixation than distance fixation after full hypermetropic correction. Aim and objectives: To clearly illustrate how medial rectus muscles combined recession and resection surgery affects convergence-excess accommodating esotropia to produce the best possible binocular vision. Patients and methods: The prospective case-series study was conducted on 42 patients at Ophthalmology outpatient clinics in Benha University hospitals. Results: There was a high statistically significant difference between the near angle data and the stereopsis before and after operation p < 0.001. The mean change in disparity was 26.33 ± 7.97 SD with range (3-35) degree and according to outcome there were 39 (92.9%) successful and 3 (7.1%) under correction. Conclusion: Convergence in accommodating esotropia undergoes considerable alterations before and after medial rectus combined resection and recession.
