What Researchers Did
Researchers treated four patients suffering from radiation-induced optic neuropathies with hyperbaric oxygen therapy.
What They Found
Two patients who began hyperbaric oxygen therapy within 72 hours of unilateral visual loss experienced a return of visual function to baseline levels. In contrast, the other two patients who started treatment two to six weeks after visual loss in their second eye showed no significant visual improvement.
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 the extremely small sample size of only four patients, which limits the generalizability of the findings.
