H35: Other retinal disorders

H35.2: Other proliferative retinopathy

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.

New blood vessels or tissues have formed in your retina. This happens after injuries to the retina, for example. There may be bleeding from the additional blood vessels. The retina may also become damaged or detached.

If there are new blood vessels in the retina, there are often no symptoms at all initially. When there is retinal bleeding or retinal damage, one may see gray spots or shadows. One’s vision may then be worse, too. One may see things distorted or in unusual colors.
