Fusional Convergence in Childhood Intermittent Exotropia

Purpose To evaluate fusional convergence and associations with control in children with intermittent exotropia (XT). Design Retrospective case series. Methods Sixty-four children (median age 7 years) with intermittent XT were identified with measures of angle of deviation, control (using a previously reported 0-to-5-point scale), and fusional convergence at a single examination. Total convergence was defined as the sum of the angle of deviation...
