Symptoms of eye cancer

Men and women discussing eye cancer

This page tells you about the symptoms of eye cancer. There are many symptoms. These include

  • Bulging of one eye
  • Complete or partial loss of sight
  • Pain in or around the eye (rare with eye cancer)
  • A pale raised lump on the surface of the eye (the conjunctiva or cornea)
  • Blurred vision
  • Change in the appearance of the eye

Eye cancer can also cause

  • Seeing spots or flashes of light or wiggly lines in front of your eyes
  • Blinkered vision (loss of peripheral vision) – you can see what is straight ahead clearly, but not what is at the sides
  • A dark spot on the coloured part of the eye (the iris) that is getting bigger
  • Eye irritation, red eye or chronic inflammation of the conjunctiva (conjunctivitis)

Pain is quite rare unless the cancer has spread to the outside of the eye, or has caused the pressure inside the eye (intraocular pressure) to become too high.

Remember that cancer of the eye is rare. And 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 GP. The earlier a cancer is picked up, the easier it is to treat it and the more likely the treatment is to be successful.
