ICON-PM: International Consensus on Nomenclature for Adult Pathologic Myopia.

Progress in retinal and eye research · 2026
Purpose

To develop an international consensus on terminology for adult pathologic myopia based on contemporary imaging, with emphasis on optical coherence tomography (optical coherence tomography).

Methods

An international panel of 32 experts in myopia and retinal disease from 13 countries was assembled.

n = 32 experts
Results
90.9%
experts agreed the new terms clearly, showing strong overall consensus
n = 32 experts
More results

Forty-four consensus statements were developed that met the predefined threshold for agreement after iterative revision.

The framework emphasizes structural definitions derived from optical coherence tomography and multimodal imaging rather than fundus appearance.

“
Conclusion · 1 of 2

This consensus establishes a unified, imaging-based lexicon for adult pathologic myopia grounded in structural anatomy and contemporary imaging.

Conclusion · 2 of 2

By organizing disease features into six domains and defining entities using optical coherence tomography, the framework reduces ambiguity, improves reproducibility, and provides a foundation for future classification systems, clinical studies, and therapeutic trials.
