Monitoring axial length (AL) progression before treatment may help predict the effectiveness of optical myopia control interventions, according to a study.
Researchers evaluated 128 eyes from 64 pediatric patients who used defocus incorporated multiple segments (DIMS) spectacle lenses, dual-focus, multifocal, or orthokeratology contact lenses.
Overall, 33% of eyes were classified as having a successful treatment outcome, and 32% achieved the average AL reduction rate observed in similar clinical studies. The mean age-adjusted reduction in AL progression was 0.11 mm per year.
Regression analyses identified a significant model only when success was evaluated using an individual-based AL change method. In that analysis, a faster AL progression rate before treatment was the sole significant predictor of a greater reduction in AL growth during intervention.
The investigators noted substantial variability in treatment response and an overall success rate of 33%. They concluded that tracking AL progression before initiating treatment may offer advantages for predicting and measuring outcomes in children undergoing optical myopia management.
