Hyperbaric Oxygen Therapy For Central Retinal Artery Occlusion – Some Resources

The following is from Resource (1) below:

Central retinal artery occlusion (CRAO) is a relatively rare emergency and potentially devastating condition of the eye. Patients present with sudden, painless monocular vision loss. The prognosis for visual recovery is poor, and up until recently, no treatment could be offered to restore at least some functional vision to the affected eye. The retina has the highest oxygen consumption rate of any organ in the body at 13 mL/100 gm per min. Retinal tissue is not tolerant of hypoxia. Until 2006 when hyperbaric oxygen therapy was approved for treatment of central retinal artery occlusion, ophthalmologists had no treatment options for these patients. It is still a vastly underutilized modality, partially due to lack of availability and lack of knowledge in the ophthalmology community.
