Central retinal artery occlusion; Branch retinal artery occlusion; CRAO; BRAO
There is no proven treatment for vision loss that involves the whole eye, unless it is caused by another illness that can be treated.
Several treatments may be tried. These treatments must be given within 2 - 4 hours after symptoms begin to be helpful. However, the benefit of these treatments has never been proven, and they are rarely used.
The health care provider should look for the cause of the blockage. Blockages may be signs of a life-threatening medical problem.
People with blockages of the retinal artery may not get their vision back.
Call your health care provider if you have sudden blurring or vision loss.
