Treatment of a Retinal Artery Occlusion
Several treatments 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 a retinal artery occlusion, although vision is often not as good as it was before. In some cases, vision loss can be permanent.
