Official title
A Randomized Trial Comparing Patching With Active Vision Therapy to Patching With Control Vision Therapy as Treatment for Amblyopia in Children 7 to <13 Years Old
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is comparing the effectiveness of patching combined with active vision therapy plus near activities versus patching combined with control vision therapy plus near activities for moderate amblyopia (20/40-20/100) in 7 to \<13 year olds. The primary outcome measure is the proportion of patients with visual acuity of 20/25 or better in the amblyopic eye at the 17-week masked exam. These patients will be considered treatment responders. The primary analysis will consist of a comparison between the 2 treatment groups of the proportion of treatment responders with adjustment for baseline visual acuity. Secondary outcomes are stereoacuity at the 17-week masked exam, mean improvement in visual acuity at the 17-week masked exam, and rate of improvement of visual acuity.
