Intermittent Exotropia: Our Experience in Surgical Outcomes

Abstract

Introduction: Exotropia is ocular misalignment with outward deviation of eyes. Exodeviation is about 25% of all deviations. Incidence is about 32.1/1,00,000 under 19 years of age. Exotropia can be divided into comittant or incomittant. Aim: To compare the surgical outcomes of unilateral recession resection versus bilateral recession in intermittent exotropia. Methodology: Inclusion criteria: Patients age >5 years, Exotropia between 25-45 Prism Diopters. Exclusion criteria: Vertical squint, Paralytic squint, Previous history of squint surgery, Ocular diseases corneal, lenticular and fundal pathology, Patient not willing for surgery, not coming for follow up. After complete examination randomized age group were selected and were grouped in two groups. Group A underwent unilateral lateral rectus recession and medial rectus resection. Group B underwent bilateral lateral rectus recession. Surgery was performed by a single surgeon. Results: Total 66 patients were included in the study. Maximum patient were in 21-25 years in both groups. Female preponderance was present. Cosmetic symptoms were present in all age group. Maximum patients were having 30 PD in both groups. There was no statistical difference in both group. Surgical outcomes were approximately equal in both groups. Conclusion: Outcome of unilateral recession of lateral rectus and resection of medial rectus versus bilateral lateral rectus recession were found to be equal with no significant statistics.
