Three-Year Observation of Children 3 to 10 Years of Age with Untreated Intermittent Exotropia.

ABSTRACT:

Purpose

To describe the course of intermittent exotropia (IXT) in children followed up without treatment for 3 years.

Design

Observation arm from randomized trial of short-term occlusion versus observation.

Participants

One hundred eighty-three children 3 to 10 years of age with previously untreated IXT and 400 seconds of arc (arcsec) or better near stereoacuity.

Methods

Participants were to receive no treatment unless deterioration criteria were met at a follow-up visit occurring at 3 months, 6 months, or 6-month intervals thereafter for 3 years.

Main outcome measures

The primary outcome was deterioration by 3 years, defined as meeting motor criterion (constant exotropia ≥10 prism diopters [Δ] at distance and near) or near stereoacuity criterion (≥2-oct
