Eight-Year Outcomes of Bilateral Lateral Rectus Recessions versus Unilateral Recession-Resection in Childhood Basic-Type Intermittent Exotropia.

ABSTRACT:

Purpose

To report 8-year outcomes from a randomized controlled trial (RCT) comparing bilateral lateral rectus muscle recession (BLRc) with unilateral recession-resection (R&R) for childhood intermittent exotropia (IXT).

Design

Eight-year follow-up of RCT cohort.

Participants

Of 197 randomized participants, 123 agreed to continue follow-up after the 3-year outcome visit (baseline age, 3-< 11 years; basic-type IXT, 15-40 prism diopters [Δ] by prism and alternate cover test [PACT]; baseline stereoacuity, ≤ 400 arcsec; no prior surgery).

Methods

After the RCT primary outcome at 3 years, annual follow-up from 4 through 8 years with treatment at investigator discretion.

Main outcome measures

Suboptimal surgical outcome by 8 years after randomization, defined a
