What Researchers Did
Researchers investigated the effects of hyperbaric oxygen therapy in nine patients with non-arteritic anterior ischaemic optic neuropathy who had not responded well to corticosteroids.
What They Found
Among the nine patients, four with optic disc atrophy showed no improvement in visual functions after hyperbaric oxygen treatment. However, the other five patients without optic disc atrophy experienced improved visual acuity and visual field, which were maintained at a six-month follow-up.
What This Means for Canadian Patients
This small study suggests that hyperbaric oxygen therapy might offer a potential new treatment option for Canadian patients with non-arteritic anterior ischaemic optic neuropathy, particularly those without optic disc atrophy. However, larger, controlled studies are needed to confirm these preliminary findings before it can be widely adopted.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A significant limitation of this study is its small sample size and uncontrolled design, which necessitates further controlled clinical trials to accurately assess efficacy.
