Top Three Myths About Measuring Axial Length for Myopia Management

In a recent webinar, Myopia Management 101: The Importance of Measuring Axial Length, Maria Liu, OD, MPH, PhD, FAAO, shared the clinical and scientific importance of integrating axial length in a pediatric myopia management practice. After the webinar she also unpacked the top three myths about measuring axial length for myopia management.

Key takeaways

  • Axial length measurements are critical for reliable evaluation of myopia progression and treatment efficacy.
  • Start early and monitor for longitudinal changes; snapshots of AL are much less informative.
  • The younger the patients, the more variability due to age-related ocular growth.
