Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is designed to evaluate the effectiveness of increasing prescribed patching treatment from 2 to 6 daily hours after visual acuity has stabilized with initial treatment and amblyopia is still present. Children ages 3 to \<8 years with visual acuity of 20/50 to 20/400 in the amblyopic eye will be enrolled in a run-in phase with 2 hours daily patching until no improvement, followed by randomization of eligible patients to patching 2 hours daily versus an average of 6 hours daily (42 hours per week). The primary objective is to determine if increasing patching dosage will improve visual acuity in patients with amblyopia still present after visual acuity has stabilized with initial treatment.
