What Researchers Did
Researchers conducted a double-blind clinical experiment to evaluate the effect of hyperbaric oxygen therapy on visual fields in 51 glaucoma patients.
What They Found
The experimental group (31 patients) showed significant improvement in visual fields (p < 0.05), while the control group (20 patients) experienced no change. Hyperbaric oxygen did not affect intraocular pressure, and visual field improvements were stable for 3 months (p 0.05).
What This Means for Canadian Patients
Canadian glaucoma patients might experience short-term visual field improvements with hyperbaric oxygen therapy, but these benefits appear to diminish after three months. This therapy did not affect intraocular pressure, which is a key factor in glaucoma management.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation of this study is the short duration of the observed visual field improvements, which significantly diminished after six months.
