Symptoms of Eye Cancer

In general, eye cancer is normally painless unless a tumor has grown outside the eye. Some eye cancers, such as intraocular melanoma, often have no symptoms. Your eye physician may find this type of melanoma during a routine eye exam or you might notice loss of vision.

Other types of eye cancers may have different symptoms, including:

  • Vision problems (blurry vision or sudden vision loss)
  • Floaters (spots or squiggles drifting in the field of vision)
  • Flashes of light
  • Visual field loss (losing part of eyesight)
  • Dark spot growing on the iris, the colored part of the eye
  • Change in the size or shape of the pupil
  • Change in position of the eyeball within its socket
  • Change in how the eye moves within the socket
  • Bulge in the eye

These symptoms may also result from conditions that are not cancer. If you have any of these symptoms, it is important to see an ocular oncologist. As in most cancers, early detection and treatment increases the chance for a cure.
