Treatment of a Retinal Artery Occlusion
Several treatments for retinal artery occlusion (RAO) may be tried but none have ever been proven to help consistently. These treatments must be given within a few hours after symptoms begin to be helpful. Treatments include:
- Breathing in (inhaling) a carbon dioxide-oxygen mixture. This treatment causes the arteries of the retina to widen (dilate)
- Removing some liquid from the eye to allow the clot to move away from the retina
- A clot-busting drug
Some patients regain vision after an RAO, although vision is often not as good as it was before. In some cases, vision loss can be permanent.
