A Randomized Trial Comparing Bilateral Lateral Rectus Recession versus Unilateral Recess and Resect for Basic-Type Intermittent Exotropia.

ABSTRACT:

Purpose

To compare long-term outcomes after bilateral lateral rectus recession (BLRc) or unilateral lateral rectus recession combined with medial rectus resection in the same eye (R&R) for primary treatment of childhood intermittent exotropia (IXT).

Design

Multicenter, randomized clinical trial.

Participants

One hundred ninety-seven children 3 to younger than 11 years of age with basic-type IXT, a largest deviation by prism and alternate cover test at any distance of 15 to 40 prism diopters (PD), and near stereoacuity of at least 400 seconds of arc.

Methods

Random assignment to BLRc or R&R and masked examinations conducted every 6 months after surgery for 3 years.

Main outcome measures

Proportion of participants meeting suboptimal surgical outcome by 3 y
