Study Summary
The objective of this short-term, pilot randomized trial comparing 2.50 diopters (D) overminus lens treatment vs. non-overminus (spectacles without overminus or no spectacles) in children with intermittent exotropia (IXT) 3 to \<7 years of age is to determine whether to proceed to a full-scale, longer-term randomized trial.
Primary Outcome
At each visit, control of the exodeviation was measured at distance (6 meters) and at near (1/3 meters) using the Office Control Score\* which ranges from 0 (phoria, best control) to 5 (constant exotropia, worst control). Due to the variability of single measures of control, we used a "triple control score," which is a mean of 3 measures obtained at specific time-points during a 20- to 40-minute office examination. The primary analysis was an intention-to-treat treatment group comparison of mean
