Objective: To study the results of large (6 and 7mm) bimedial rectus recessions in large-angle (50 prism dioptres or greater) congenital esotropes. Design: A prospective study on nineteen patients of congenital esotropia registered from May 1994 to December 1996 for 6 and 7mm bimedial rectus recessions. Setting: Indoor patients of general community at the Department of Ophthalmology, Unit-1, Eye Hospital, Liaquat Medical College, Jamshoro/Hyderabad. Main Outcome Measures: Correction of large-angle esotropes by large bimedial rectus recessions. Results: Nineteen congenital esotropes having deviations of 50 to 80 prism dioptres underwent 6 and 7mm, bimedial rectus recessions. The refractive errors ranged from -1.50 to +3.00 dioptres and age at surgery ranged from 2 to 12 years. Of the 19 cases, 15 patients (78.40%) achieved successful alignment within 10 prism dioptres. Four patients were undercorrected and no patient had overcorrection. Conclusion: Large (6 and 7mm) bimedial rectus recessions in 19 congenital esotropes with deviations of 50 to 80 prism dioptres provided successful alignment within 10 prism dioptres of orthophoria in 78.94% of cases.
