Central Retinal Artery Occlusion

Central retinal artery occlusion is a sudden blockage of the eye's main artery — an emergency that can cause permanent vision loss within hours. Hyperbaric oxygen therapy, FDA-approved for this indication, sustains oxygen to the retina while the blockage is addressed, preserving retinal tissue and improving the chance of saving sight.
