What Researchers Did
Researchers reported on a 70-year-old male with central retinal artery occlusion (CRAO) who received hyperbaric oxygen therapy (HBOT) within 48 hours of symptom onset.
What They Found
A 70-year-old male presented with painless vision loss in his right eye, with initial light perception. Hyperbaric oxygen therapy (HBOT) was initiated within 48 hours of presentation, leading to an improvement in vision where light perception expanded beyond the peripheral area after the first treatment.
