A randomized trial comparing part-time patching with observation for children 3 to 10 years of age with intermittent exotropia.

ABSTRACT:

Objective

To determine the effectiveness of prescribed part-time patching for treatment of intermittent exotropia (IXT) in children.

Design

Multicenter, randomized clinical trial.

Participants

Three hundred fifty-eight children 3 to <11 years of age with previously untreated (except for refractive correction) IXT and near stereoacuity of 400 seconds of arc or better were enrolled. Intermittent exotropia met the following criteria: (1) IXT at distance OR constant exotropia at distance and either IXT or exophoria at near; (2) exodeviation (tropia or phoria) of at least 15 prism diopters (PD) at distance or near by prism and alternate cover test (PACT); and (3) exodeviation of at least 10 PD at distance by PACT.

Methods

Participants were assigned randomly either t
