What Researchers Did
Researchers investigated adding hyperbaric oxygen therapy to standard treatment for five patients with persistent macular oedema of vascular origin.
What They Found
Five patients (seven eyes) with macular oedema received 10-30 hyperbaric oxygen treatments (median 15). After treatment, the average visual acuity improved by 3.5 lines. While diabetic macular oedema showed no structural changes, macular oedema caused by retinal vein occlusions improved, though most cases still required photocoagulation.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This was a small case report involving only five patients, which limits how broadly its findings can be applied.
