Quantitative imaging biomarkers are essential to advancing precision medicine within ophthalmology, providing objective insights into structural changes, disease progression, and treatment response. However, the path to their qualification and widespread adoption faces a significant hurdle: interoperability among imaging devices. In this presentation, we explore the role of industry standards and calibration phantoms in addressing the challenge of quantitative interoperability. We will review Maxwellian optics of the eye and implications for calibrating fundus cameras, OCT, and Adaptive Optics enabled retinal imaging systems. We explore how uniform and transparent calibrations can empower structural biomarker discovery and drive progress in ophthalmic clinical trials and personalized care.
