Capturing the Moment of Fusion Loss in Intermittent Exotropia.

ABSTRACT:

Purpose

To characterize eye movements made by patients with intermittent exotropia when fusion loss occurs spontaneously and to compare them with those induced by covering 1 eye and with strategies used to recover fusion.

Design

Prospective study of a patient cohort referred to our laboratory.

Participants

Thirteen patients with typical findings of intermittent exotropia who experienced frequent spontaneous loss of fusion.

Methods

The position of each eye was recorded with a video eye tracker under infrared illumination while fixating on a small central near target.

Main outcome measures

Eye position and peak velocity measured during spontaneous loss of fusion, shutter-induced loss of fusion, and recovery of fusion.

Results

In 10 of 13 subjects, t
