What Researchers Did
Researchers conducted a prospective, single-center study to evaluate the efficacy and safety of hyperbaric oxygen therapy (HBOT) monitored by fluorescein angiography (FA) for patients with retinal artery occlusion (RAO).
What They Found
Thirty-one patients with retinal artery occlusion received hyperbaric oxygen therapy, with retinal revascularization observed in 87.1% by day 21. The mean best-corrected visual acuity improved from 1.51 logMAR on referral to 1.10 logMAR at one month, with 48.4% of patients achieving a significant improvement. Minor barotrauma occurred in 19.4% of patients.
What This Means for Canadian Patients
Hyperbaric oxygen therapy may offer a potential treatment option for Canadian patients experiencing retinal artery occlusion, showing promise in improving visual acuity and promoting retinal revascularization. Patients should discuss this therapy with their ophthalmologist to understand its potential benefits and risks.
Canadian Relevance
This study was not conducted in Canada and does not have a direct Canadian connection.
Study Limitations
Limitations include the study's single-center design, non-comparative nature, and relatively small sample size of 31 patients.
