Summary

What Researchers Did

Researchers retrospectively analyzed the outcomes of hyperbaric oxygen treatment (HBOT) for retinal artery occlusion (RAO) in 22 patients at an Australian hospital between 2015 and 2021.

What They Found

For central RAO, 8 out of 17 patients (47%) experienced objective improvement in best corrected visual acuity, with an average LogMAR improvement of -0.2. An additional 4 patients reported subjective improvement, bringing the total to 12 out of 17 (71%) experiencing some form of improvement. However, none of the five patients with branch RAO showed improvement in best corrected visual acuity.

Canadian Relevance

This study was conducted at a major Australian hospital and does not have a direct Canadian connection.

Study Limitations

This was a retrospective study with a small sample size of 22 patients, which limits the generalizability of the findings.
