One-muscle strabismus surgery: A review

Proper management of a patient with small to moderate horizontal deviations continues to be challenging for the strabismus surgeon. The use of one-muscle surgery for comitant strabismus has been controversial because of concerns that it may result in a significant number of undercorrections and/or ocular incomitance. Recent literature on unilateral rectus muscle surgery has shown that this surgery is a safe and effective procedure for small and moderate angle horizontal deviations. It has the advantage of limiting surgery to one eye, reducing operative time and possible cost to the family, and leaving other muscles untouched in case repeat surgery is necessary. Larger studies need to be done in the future; however, this surgery should be considered as a primary approach in the treatment of small to moderate angle esotropia
