Eye scans may spot early damage from sleep apnea
NCT ID NCT03979001
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed pilot study looked at whether a quick, non-invasive eye scan (OCT angiography) can detect early blood vessel changes in the retina of people with obstructive sleep apnea. Researchers compared 166 adults with and without sleep apnea. The goal was to see if retinal imaging could reveal microvascular damage linked to sleep apnea, which might help assess cardiovascular risk in the future.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could show that eye scans help detect early blood vessel damage from sleep apnea, potentially guiding future cardiovascular risk screening.
What could go wrong
This is a small, early pilot study with no treatment tested. Results may not lead to a practical screening tool, and findings need confirmation in larger trials.
