What is ocular lymphoma?
24 March 2022
Lymphoma is a cancer that starts in the white blood cells and can occur in the eyes. This type of eye cancer is called primary intraocular lymphoma (PIL). LIOP can develop in the retina and vitreous humor inside the eye. It also affects the optic nerve at the back of the eye.
According to the American Academy of Ophthalmology (AAO), eight out of ten people have LIOP in both eyes. Also, many people with this type of cancer may have it in a part of the brain, called primary central nervous system lymphoma.
What causes ocular lymphoma and who is at risk?
When the immune system is not working properly, there is a risk of developing primary intraocular lymphoma (POIL). Some people may have changes in their cells that increase their risk of developing eye cancer. Also at risk for ocular lymphoma are people:
- older age;
- with rheumatoid arthritis;
- with certain medical problems that affect their immune system;
- with AIDS (acquired immunodeficiency syndrome)
- who are receiving certain medications to prevent the body from rejecting a transplanted organ.
Symptoms of ocular lymphoma
The most common symptoms of ocular lymphoma include:
- blurred vision
- vision impairment or loss of vision
- floatersphotophobia (sensitivity to light)
As mentioned above, lymphoma usually affects both eyes, although symptoms may be more pronounced in only one eye.
