Comparative Study of Unilateral Recession Resection Versus Bilateral Recession in Intermittent Exotropia

Abstract

Aim: To compare the surgical outcome of unilateral recession resection versus bilateral recession in intermittent exotropia. Material & Method: This was a prospective randomized control study that included 40 patients of intermittent exotropia attending outpatient Department of Ophthalmology, Subharti Medical College, Meerut. Age matched randomization of patients was done in two groups of 20 each. Patients in group A underwent unilateral lateral rectus recession and medial rectus resection while those in group B underwent bilateral lateral rectus recession. Surgery was performed by a single surgeon and the amount of muscle recession or resection was decided on the basis of the degree of deviation. Patients were evaluated at 1st postoperative day, 1week, 6 weeks and 12 weeks. The postoperative outcome was considered satisfactory if there was esophoria 10 PD esophoria and one patient in group B had > 10 PD exophoria. Conclusions: Therefore, unilateral recession resection and bilateral recession are equally effective in the treatment of intermittent exotropia.
