Brief summary

Comparison Between The Results Of Two Muscles Surgery And Three Muscles Surgery For The Treatment Of Large Angle Exotropia

Detailed description

Exotropia is classified as Primary which includes constant and intermittent exotropias. Secondary XT include Sensory and consecutive XT. Management for IXT consists of non-surgical and surgical treatment. There is some controversy regarding the optimal surgical method varying between bilateral lateral rectus recession (BLR), unilateral lateral rectus recession-medial rectus resection (RR) and bilateral medial rectus resection (BMR).

Interventions

PROCEDUREsurgery

69 Patients with exotropia of (40-55) PD who are ≥ 5 years old. The 1st group 30 patients had two muscles surgery; bilateral lateral rectus recession. The 2nd group 39 patients had three muscles surgery; bilateral lateral rectus recession and unilateral medial rectus tucking.
