Symptoms of eye cancer

This page tells you about the symptoms of eye cancer. There are several symptoms. Other eye conditions that aren’t eye cancer can cause many of these symptoms. But it is important that you report any of them to your doctor. People with eye cancer may have

Bulging of one eye
Complete or partial loss of sight
Pain in or around the eye (rare with eye cancer)
Watery eyes
Blurred vision

Eye cancer can also cause

Seeing spots, flashes of light or wiggly lines in front of your eyes. These are called floaters. They are also a natural part of getting old.
Blinkered vision (loss of peripheral vision) - you can see what is straight ahead clearly, but not what is to the sides
A dark spot on the coloured part of the eye (the iris) that is getting bigger

Pain is quite rare unless the cancer has spread to the outside of the eye.
