H34.1: Central retinal artery occlusion
A blood vessel has closed up in the retina in your eye.
The retina is a layer inside the eye. It contains a lot of sensory cells that can perceive light. There are sensory cells for colors and sensory cells for light and dark. The sensory cells pass the information on to the nerve cells in the optic nerve.
An artery supplies the retina with oxygen-rich blood and nutrients.
In your case, this retinal artery in your eye has closed up.
When an artery in the eye closes up, the retina no longer receives sufficient blood. Suddenly there is no vision from the eye.
Blood vessels can close for different reasons. A blood clot can block the blood vessel, for example. Or fats and calcium may have been deposited in the blood vessel. This gradually makes the blood vessel narrower and it can sometimes close up entirely.
