Monitoring Myopia Progression

Effective monitoring is essential for assessing treatment success and adjusting management strategies.

Key Metrics

Axial Length

• Most important metric
• Directly measures eye growth
• Less variable than refraction
• Gold standard for research

Refraction

• Traditional measure
• Subject to variability
• Affected by accommodation
• Use cycloplegic for accuracy

Visual Acuity

• Functional outcome
• Patient-relevant
• May not reflect progression
• Important for quality of life

Measurement Protocols

Axial Length

• Use optical biometry
• Consistent technique
• Same instrument when possible
• Document conditions

Refraction

• Cycloplegic for children
• Consistent methodology
• Control accommodation
• Document technique

Topography

• Essential for Ortho-K
• Baseline and follow-up
• Consistent positioning
• Quality control

Monitoring Schedule

Initial Phase

• Baseline: comprehensive measurements
• 1 month: early response
• 3 months: treatment effect
• 6 months: confirm trajectory

Maintenance Phase

• Every 6 months: standard
• More frequent if concerns
• Annual comprehensive review
• Adjust based on response

Interpreting Results

Expected Outcomes

• Axial length: <0.2mm/year on treatment
• Refraction: <0.50D/year on treatment
• Compare to untreated progression

Treatment Success

• Slower than expected progression
• Stable or improved metrics
• Good visual function
• Patient satisfaction

Treatment Failure

• Continued rapid progression
• >0.3mm axial growth/year
• Consider treatment change
• Reassess compliance

Documentation

Essential Records

• All measurements with dates
• Treatment parameters
• Compliance assessment
• Clinical decisions

Tracking Tools

• Myopia management software
• Growth charts
• Comparison to norms
• Trend analysis

Adjusting Treatment

When to Modify

• Inadequate response
• Side effects
• Compliance issues
• Patient preference

Options

• Increase treatment intensity
• Add combination therapy
• Switch treatments
• Optimize compliance

Communicating Results

To Parents

• Explain metrics clearly
• Show progress visually
• Discuss implications
• Plan next steps

Documentation

• Clear progress notes
• Treatment rationale
• Parent communication
• Future plans
