Effect of augmented recession on a rectus muscle

ABSTRACT

Forty patients from the University of Alexandria Main Hospital, with large angle deviation varying from 50 to greater than 90 diopters, were selected for this study. A recess resect technique formed was performed in unilateral amblyopia, bilateral recession was done for patients having equal vision. An adjustable suture technique was used on all patients. This permitted alterations in the immediate post operative period up to 25 diopter. The major problem in the surgical correction of large angle deviations has been persistently high rates of under correction. More recent surgical protocols advocates larger amounts of surgery per prism diopter of deviation. Ninty five percent of cases showed perfect motor alignment with two muscles only without much cripling of the movement
