Three-year observation of children 12 to 35 months old with untreated intermittent exotropia.

ABSTRACT:

Purpose

To describe the clinical course of untreated intermittent exotropia (IXT) in children 12-35 months of age followed for 3 years.

Methods

We enrolled 97 children 12-35 months of age with previously untreated IXT who had been randomly assigned to the observation arm of a randomised trial of short-term occlusion versus observation. Participants were observed unless deterioration criteria were met at a follow-up visit occurring at 3 months, 6 months, and 6-month intervals thereafter for 3 years. The primary outcome was deterioration of the IXT by 3 years, defined as (1) a constant exotropia ≥10 prism dioptres (∆) at distance and near (i.e., motor deterioration) or (2) treatment prescribed despite not having met motor deterioration. The primary analysis used the Kaplan-Mei
