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

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.
