What Researchers Did
Researchers at two medical centers reviewed outcomes in 65 patients with central retinal artery occlusion (CRAO), a stroke of the eye, comparing those who completed a full 10-session HBOT course, those who received partial HBOT, and those who received no HBOT.
What They Found
Patients who completed a full HBOT course (twice daily for 5 days) showed significant visual improvement at discharge (p = 0.01, measured by LogMAR visual acuity). Patients who received partial HBOT or no HBOT did not show significant improvement. Only one patient had a seizure during treatment; no other complications were reported.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This was a small retrospective study (65 patients across two centers) with no randomised control group, and patients chose or declined HBOT rather than being randomly assigned.
