Meridional amblyopia persists after correcting astigmatism.

Meridional amblyopia persists after correcting astigmatism.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

Meridional amblyopia comes from uneven blur along one axis caused by astigmatism during early visual development. When one meridian is consistently blurred, the brain learns to rely on the clearer meridian and suppresses the information from the blurred one. Even after you correct the astigmatic error optically, the neural pathways may have developed in a way that doesn’t fully recover, so the reduced acuity along the affected meridian can persist. Early detection and treatment with proper refractive correction plus amblyopia therapy (like patching or penalization) can improve outcomes, but persistence after correction is a recognized possibility.
