What Is Eye Lymphoma?

Lymphoma is a type of cancer that can affect the eye.

One type of eye cancer is called primary intraocular lymphoma (PIOL). PIOL can develop in the retina and in the vitreous inside the eye. It also affects the optic nerve at the back of the eye.

Eight out of 10 people who have PIOL get it in both eyes. Many people with PIOL also have lymphoma in a part of their brain. This is called primary central nervous system lymphoma.

PIOL is almost always a type of lymphoma called non-Hodgkin’s B cell lymphoma. Most people who have it are elderly or have immune system diseases.
