What Researchers Did
Researchers retrospectively analyzed visual acuity outcomes in 114 adult patients with central retinal artery occlusion (CRAO) treated with hyperbaric oxygen therapy (HBOT) at a Portuguese hospital.
What They Found
The study included 114 patients, 68% (n=77) of whom were male with a mean age of 69 years, who underwent a median of seven HBOT sessions. The provided abstract is incomplete and does not detail the primary outcome of visual acuity change (dif-logMAR) before and after treatment, which was defined as clinically significant if ≥0.3.
Canadian Relevance
This study was conducted in a Portuguese hospital and has no direct Canadian connection.
Study Limitations
As a retrospective study, it is subject to inherent biases and limitations associated with data collection from past records.
