Improved Assessment of Control in Intermittent Exotropia Using Multiple Measures

To develop and validate an improved measure of control in intermittent exotropia (XT).Prospective, noninterventional case series.Twelve children with intermittent XT were evaluated during 4 sessions (2 hours apart) over a day, on 2 separate days (8 sessions per child). Control was standardized using a scoring system and quantified 3 times during each examination. Overall control for a day was calculated as the mean of all 12 measures. Single...
