Whole-volume OCT analysis could make retinal AI more clinically useful, but external validation, device diversity and workflow integration remain decisive tests.
What is happening
Retinal AI has traditionally focused on selected images or narrow tasks. Newer systems aim to interpret complete 3D OCT studies, preserving the spatial information clinicians actually use.
Why it matters
A model that can reason across an entire scan may be better positioned to detect subtle patterns, compare structures and support more complex decisions than one trained on isolated slices.
What the evidence says
Early research is promising, especially around foundation models and multimodal systems. But high benchmark performance is not the same thing as proven clinical utility.
The limitations
Dataset shift, scanner differences, calibration, explainability and prospective clinical testing can all change real-world performance.
What is next
Watch for multicenter validation, prospective studies and evidence that these systems improve workflow or outcomes not just accuracy metrics.
Evidence should be inspectable.
