Alternating Exotropia
Conditions
Brief summary
comparing the motor alignment and the incidence of postoperative esotropia following the correction of intermittent exotropia in children below 7 years by bilateral lateral rectus recession using the standard recession tables postulated by Parks versus correction using a reduced recession by one millimeter
Interventions
PROCEDUREStandard Recession
Bilateral lateral rectus muscle recession will be performed through fornix approach using standard tables
PROCEDUREReduced Recession
Bilateral lateral rectus muscle recession will be performed through fornix approach using reduced numbers

Inclusion criteria
* Patients with poor control intermittent exotropia (where poor control is defined as having a Newcastle score of 3 or more). (9) * Basic, pseudo- divergence excess and divergence excess types are included. * If associated with amblyopia it should be corrected before the surgical correction (where the visual acuity will be assessed by the single crowded HOTV test using a commercial projector).
Exclusion criteria
* Intermittent exotropia of the convergence insufficiency type. * Intermittent exotropia with angle of deviation greater than 50 prism diopters. * Patients with previous squint surgery. * Patients with secondary deviation due to a sensory lesion or neurological condition.
