Bil. LR Rec. Using Standard Tables VS Reduced Numbers in Intermittent Exo. in Children Under 6

Not Applicable

• Conditions: Alternating Exotropia
• Interventions: Procedure: Standard Recession; Procedure: Reduced Recession

• Registration Number: NCT04308538
• Lead Sponsor: Cairo University

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

Recruitment & Eligibility

• Status: UNKNOWN
• Sex: All
• Target Recruitment: 100

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.
