What Researchers Did
Researchers retrospectively analyzed 128 patients with central retinal artery occlusion (CRAO) who received hyperbaric oxygen therapy (HBOT) to evaluate its effect and identify markers for irreversible retinal damage.
What They Found
Best-corrected visual acuity (BCVA) significantly improved after HBOT, from 2.14±0.50 to 1.61±0.78 (p<0.001), with 63% of patients showing improvement. The mean time from symptom onset to treatment was 7.8±3.8 hours, and fundus findings, rather than time delay, were identified as markers for irreversible damage.
What This Means for Canadian Patients
Canadian patients experiencing sudden vision loss due to central retinal artery occlusion might benefit from hyperbaric oxygen therapy, especially if treated promptly before irreversible damage occurs. Prompt medical attention and assessment of fundus findings are crucial to guide treatment decisions.

Study Limitations
As a retrospective analysis, this study is subject to potential selection bias and unmeasured confounding factors.
