A retinal artery occlusion (RAO) happens when there is a blockage of blood flow to the retina in the back of the eye. Symptoms include sudden vision loss, distorted vision or blind spots in your vision. Certain health conditions like diabetes and high blood pressure increase your risk for having an RAO.
If you have symptoms of an RAO, see an ophthalmologist as soon as possible. They can look for signs of damage and treat you if necessary. In some cases, patients can regain vision after an RAO. In others, however, vision loss can be permanent. This is why it is so important to see an ophthalmologist or doctor at the first sign of any symptoms.
