What Researchers Did
Researchers conducted a case series of 11 patients with retinal artery occlusion treated with hyperbaric oxygen therapy (HBOT) and combined this data with two other case series for a total of 51 patients.
What They Found
In their own case series, 8 out of 11 patients achieved improved visual acuity. Across the combined 51-patient case series, 74% of patients treated with HBOT showed improved visual acuity (P < 0.0001), with 53% improving by two or more lines on a Snellen value. Visual acuity improved across all time-from-occlusion to treatment categories, even up to six days.
What This Means for Canadian Patients
Canadian patients experiencing recent retinal artery occlusion might consider hyperbaric oxygen therapy (HBOT) as a potential treatment option. This therapy could lead to improved visual acuity, even if treatment is initiated several days after the occlusion.
Canadian Relevance
This study has no direct Canadian connection as it was conducted in the United States and did not involve Canadian participants or institutions.
Study Limitations
A significant limitation of this study is its reliance on case series data, which lacks a control group and may be subject to selection bias.
