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

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).
