A new "Eye-Stroke" protocol using bedside retinal imaging in the ER is dramatically cutting diagnosis times for acute retinal artery occlusions — the eye's equivalent of a stroke. Researchers at Emory University found that immediate nonmydriatic fundus photography and OCT reduced median diagnosis time from 3 hours to just 28.5 minutes for early-presenting patients. The approach also opens the door to time-sensitive thrombolysis treatment.
Think of a retinal artery occlusion as a stroke in the eye — and just like a brain stroke, every minute counts. Researchers at Emory University School of Medicine developed the "Eye-Stroke" protocol, which deploys nonmydriatic fundus photography and optical coherence tomography (NMFP-OCT) immediately for any ED patient presenting with vision complaints. For patients arriving within 6 hours of vision loss, both ophthalmology and stroke neurology teams are paged simultaneously, and an on-call ophthalmologist remotely interprets the imaging to confirm diagnosis — no in-person exam required.
The results, published in Frontiers in Neurology, were striking. Reviewing 100 eyes with central or branch retinal artery occlusion (CRAO/BRAO) from 2023–2026 versus a historical cohort from 2010–2020, the team found median diagnosis time for early presenters dropped from 3 hours to just 28.5 minutes. Of those eligible for IV thrombolysis, 43% received it — a treatment window that would have been missed under the old workflow.
By the Numbers:
Why it matters: Most EDs lack on-site ophthalmologists, causing dangerous delays in diagnosing retinal strokes. This protocol shows that remote imaging interpretation can bridge that gap — potentially saving vision and flagging concurrent brain events that might otherwise go undetected.
