Myopia Management for Eye Professionals
EVALUATING PRE-MYOPIA AND MYOPIA
Refractive Error

- Primary method for diagnosing myopia and a routine measurement in every comprehensive eye examination1
- Accuracy and repeatability improve with use of cycloplegia and objective measurements (autorefraction)2
- Strongly correlated with axial length,3 but substantially less repeatable than optical biometry even with cycloplegia4,5
- Misleading interpretation can occur with orthokeratology
Axial Length (Optical Biometry)

- Primary metric for monitoring eye elongation
- Highly repeatable measurement
- Relates directly to the pathological processes in myopia
- Doesn’t require cycloplegia
- Less susceptible to changes in the anterior optics of the eye which may occur over the course of treatment such as orthokeratology

MONITORING PRE-MYOPIA AND MYOPIA
KEY POINTS FOR MONITORING image

Key Points for Monitoring
- Young myopes will progress, so set this as the expectation6
- Average treatment efficacy can be referenced from randomized clinical trials
- Monitor Myopia management therapy use, acceptance, and maintenance every six months
- Evaluate progression using at least one (1) year of data to avoid seasonal changes7 and reduce measurement noise (even with optical biometry)
- Treatment efficacy cannot be determined for an individual patient because there is no way to know how that individual would have progressed if left untreated
- Refer to population-based normative data to assess progression (see Table 5)
