Sudesh Arya

Purpose: To find out final outcome of surgical intervention in patients with concomitant exotropia.

Material and Methods: Retrospective analysis of case records of patients having concomitant exotropia during last 3 years.

Results: Total 46 patients were included in the study with mean age of 25.5 years. Age ranged from one year to 50 years.45.6% patients had alternate divergent type, 21.7% had intermittent type while rest 34.7% had unilateral constant type of exotropia. A or V pattern was seen in 32.6% patients.Amblyopia was present in 23.9% of patients.69.5% patients could achieve parallel visual axis after horizontal muscle surgery and 75% patients with A or V pattern had parallel visual axis after vertical transposition of horizontal recti.

Conclusion: Majority of patients with concomitant exotropia requiring surgical intervention could achieve parallel visual axis along with binocular single vision.
