H32.8: Other chorioretinal disorders in diseases classified elsewhere

The choroid is the middle layer in the eye sheath. It lies between the sclera and the retina. There are lots of blood vessels in this layer. The choroid supplies the retina below it with oxygen and nutrients. 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.

The change to your choroid and retina was caused by another disorder.

If your choroid and retina change, your vision may deteriorate.
