Hyperbaric oxygen therapy in the treatment of radiation optic neuropathy

What Researchers Did

Researchers treated 4 consecutive patients with unilateral or asymmetric bilateral radiation optic neuropathy (RON) using hyperbaric oxygen (HBO) and oral corticosteroids.

What They Found

In the less affected eye, 2 of the 4 patients had preservation of vision, while the other 2 patients experienced vision decline. No patient showed improvement in the more symptomatic eye, and 2 patients had a significant decline in visual acuity.

Canadian Relevance

This study has no direct Canadian connection as it was not conducted in Canada, nor did it involve Canadian researchers or patients.

Study Limitations

This was a case report involving only 4 patients, limiting the generalizability and statistical power of the findings.
