People with intraocular melanoma often have no symptoms. Many times, an ophthalmologist finds the melanoma during a regular eye examination. The most common symptom is painless loss of vision.
People with eye cancer may experience the following symptoms or signs. Sometimes people with eye cancer do not show any of these symptoms. Or, these symptoms may be caused by a medical condition that is not cancer. If you are concerned about a symptom or sign on this list, please talk with your doctor.
- Having trouble seeing
- Losing part of the field of vision
- Seeing flashes of light
- Seeing spots, squiggly lines, or floating objects (floaters)
- Having a dark spot on the iris. Unlike choroidal and ciliary body melanoma, iris melanoma can sometimes be seen because it looks like dark spots on the eye.
Your doctor will ask you questions about the symptoms you are experiencing to help find out the cause of the problem, called a diagnosis. This may include how long you've been experiencing the symptom(s) and how often.
If cancer is diagnosed, relieving symptoms and side effects remains an important part of cancer care and treatment. This may also be called symptom management, palliative care, or supportive care. Be sure to talk with your health care team about symptoms you experience, including any new symptoms or a change in symptoms.
