A reassessment and comparison of the Landolt C and tumbling E charts in managing amblyopia

Abstract Current criteria for amblyopia do not account for difference in visual acuity charts. This prospective observational study analyzed 100 children younger than 10 years treated at a tertiary referral center. Visual acuity was separately tested in each eye using Landolt C and tumbling E charts...
