What Researchers Did
Researchers treated a 54-year-old woman with hemispheric retinal vein occlusion and macular oedema in her only seeing eye with hyperbaric oxygen.
What They Found
After two courses of twice-daily 100% hyperbaric oxygen, retinal leakage, measured by vitreous fluorophotometry, decreased from abnormal to the normal range. Visual acuity also improved by two lines.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian researchers or patients.
Study Limitations
A significant limitation of this study is that it is a single case report, meaning the findings may not be generalizable to a broader patient population.
