Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Change in corrected distance visual acuity (CDVA) of the amblyopic eye, measured using the ETDRS logMAR chart at baseline and at 1, 2, and 4 months after the intervention. Timepoint: The primary outcome will be measured at baseline (before the intervention) and at 1, 2, and 4 months after initiation of the intervention. Method of measurement: Corrected distance visual acuity is measured using the Early Treatment Diabetic Retinopathy Study distance visual acuity chart, and results are recorded on the logarithm of the minimum angle of resolution scale. | — |
