What Researchers Did
Researchers reported on a 66-year-old woman with bilateral non-arteritic anterior ischaemic optic neuropathy (NAION) who received hyperbaric oxygen (HBO2) therapy after corticosteroids failed, analyzing her visual acuity, visual evoked potentials, perimetric examination, and angiographic images.
What They Found
The patient showed significant recovery in visual acuity, visual evoked potentials, perimetric examination, and angiographic images after HBO2 therapy. These improvements remained stable during a follow-up period of approximately nine months.
Canadian Relevance
This study has no direct Canadian connection as it is a case report from outside Canada.
Study Limitations
The primary limitation of this study is its design as a single case report, which prevents generalization of findings and necessitates larger randomised controlled trials to confirm efficacy.
