Study Summary
This study will evaluate the effectiveness of refractive correction alone for the treatment of previously untreated strabismic or combined-mechanism amblyopia in children 3 to \<7 years old with visual acuity of 20/40 to 20/400
Primary Outcome
Acuity is measured in each eye using the Amblyopia Treatment Study (ATS) visual acuity testing protocol at baseline and at 18wks resulting in a Snellen acuity score that can range from 20/16 to 20/800. The score is converted to logMAR (log of min angle of resolution) for statistical analysis, and a difference between the scores is calculated. A positive difference indicates acuity was better at 18wks than at baseline; a negative difference indicates acuity was worse at 18wks than at baseline.
