What Researchers Did
Five patients with retinal artery occlusion (RAO) were treated with hyperbaric oxygen therapy (HBO2) for one hour at 1.5 ATA.
What They Found
All five patients, who had symptoms for one to 12 days, showed improvement following HBO2 treatment. Four patients had branch retinal artery occlusion and one had cilioretinal artery occlusion, with no complications reported.
What This Means for Canadian Patients
Hyperbaric oxygen therapy could potentially offer a safe treatment option for Canadian patients experiencing retinal artery occlusion, which can cause significant vision loss. This therapy might help improve visual outcomes for those affected by this condition.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The study's primary limitation is its very small sample size of only five patients.
