What Researchers Did
Researchers conducted a literature review to examine the applications and effects of hyperbaric oxygen therapy in various eye diseases.
What They Found
They found that hyperbaric oxygen therapy (HBOT) showed beneficial effects in certain microcirculatory ocular pathologies, such as central retinal artery occlusion and macular edema linked to retinal vein occlusions. HBOT might also be an alternative for ocular quinine toxicity and an adjuvant for periorbital necrotizing fasciitis. However, high concentrations of oxygen can have toxic ocular effects due to reactive oxygen derivatives.
What This Means for Canadian Patients
Canadian patients with specific eye conditions like retinal artery occlusion or macular edema might potentially benefit from hyperbaric oxygen therapy, though it is a specialized treatment. Patients should discuss the potential benefits and risks, including oxygen toxicity, with their ophthalmologist to determine if this therapy is appropriate.
