Comparison of bilateral medial rectus recession vs recession-resection as surgery for infantile esotropia

Background: Infantile esotropia is misalignment of eyes from bifoveal fixation where surgical correction at an early age usually presents with good outcomes. Aims and Objective: To compare the surgical outcome between bilateral medial rectus recession (BMR) and recession- resection (RR) surgery in infantile esotropia. Materials and Methods: The study was conducted in Lumbini Eye Institute, Bhairahawa, from December 2017 to December 2018. Patients with infantile esotropia who underwent surgical correction were included in the study. Patients were examined pre operatively, and post operatively at day one and third month, where the angle of deviation was measured and the level of binocular single vision (BSV) was assessed. Data was entered and analyzed using the SPSS program. Results: Total 79 patients were included in the study out of which 33 underwent BMR and 46 underwent RR. The mean pre-operative angle by PBCT was 52.58 PD (SD ±15.468) in the BMR group and 47.83 PD (SD ±12.140) in the RR group. Post-operative deviation in the BMR group had angle
