Central retinal artery occlusion, (CRAO), is an arterial insufficiency that causes a sudden loss of vision in one eye that is painless, but unfortunately usually permanent. A patient with CRAO should go to a hospital emergency room immediately, and should be considered for hyperbaric oxygen treatment within 24 hours of the injury. Even though hyperbaric oxygen therapy provides the best chance of recovery from CRAO, recovery from CRAO is never assured. The treatment protocol for hyperbaric therapy is complex with CRAO, depending on the patient response.
If you or a loved-one has experienced vision loss in one eye, go to the emergency room immediately and require them to approve hyperbaric oxygen therapy as your best chance for recovery!
