WHAT IS A RETINAL ARTERY OCCLUSION?
Retinal artery occlusions are a medical emergency caused by a blocked artery in the retina. The affected retina is damaged from diminished blood flow.
WHAT CAUSES RETINAL ARTERY OCCLUSIONS?
A clot or inflammation of the artery can cause it to become blocked. Risk factors include older age and cardiovascular risk factors such as high blood pressure, diabetes, or elevated cholesterol.
WHAT ARE THE SYMPTOMS OF RETINAL ARTERY OCCLUSION?
Retinal artery occlusions can cause sudden and profound painless loss of vision.
WHAT ARE THE TREATMENTS FOR RETINAL ARTERY OCCLUSION?
If diagnosed early, treatments include using medications to lower eye pressure and dislodge the clot and tests for stroke. Your doctor may order blood work and imaging tests of your eyes, brain, heart, and neck to look for additional clots.
