Macular edema is swelling caused by fluid accumulating in the macula, the central part of the retina. It can blur or distort central vision. Causes include diabetes, blocked retinal veins, inflammation and complications after eye surgery, and treatment depends on the underlying cause.
Older small studies explored HBOT for particular forms of macular edema, including inflammatory cystoid macular edema. These reports do not establish it as a standard treatment across the different causes of retinal swelling. An ophthalmologist should identify the cause, assess the risk to vision and discuss treatments with established evidence. HBOT remains investigational for macular edema and should not replace or postpone that care.
Poor arterial blood flow can cause hard-to-heal wounds or sudden loss of retinal circulation.
