What causes eye cancer?

The cause of eye cancer is unknown. But there are certain things that can increase your chance of getting cancer. These are called risk factors and include:

  • Eye colour: If you have blue, green or grey eyes, you are more likely to develop melanoma of the eye than if you have brown eyes.
  • Skin colour: If you are fair skinned, you are more likely to get eye cancer than if you have dark skin.
  • Moles: If you have moles, you have a higher risk of skin and eye melanoma.
  • Sunlight: If you expose yourself to too much sun, it increases your risk of skin melanoma but also eye melanoma and squamous cell cancer of the eye.
  • UV radiation: If you work as a welder, you may be at increased risk of melanoma of the eye. If you use sunbeds, your risk is also increased.
  • Weakened immune system: If you take medication to avoid organ rejection after a transplant, you might be at increased risk of lymphoma of the eye or squamous cell cancer of the eye. Your risk is also increased if you have certain viruses like AIDS or human papilloma virus   HPV or autoimmune diseases like rheumatoid arthritis.

What are the symptoms of eye cancer?

Eye cancer is sometimes found during a routine eye exam when your doctor dilates your pupil and looks into your eye. Intraocular melanoma may not cause any early symptoms. Some symptoms of eye cancer include:

  • Bulging of the eye
  • Some loss of sight
  • Blurred vision
  • Flashing lights
  • Shadows and misting of the eye lens
  • A dark spot on the iris
  • Watery eyes
  • Pain in or around the eye (rare)

These symptoms can also be due to diseases other than eye cancer. But do get them checked out by your doctor without delay.

Can I be screened for eye cancer?

Testing for eye cancer when you have no symptoms is called screening. There is no screening programme for eye cancer at present. If you or your brother or sister have retinoblastoma, you should get your children checked out soon after birth.
If you have any symptoms or you feel that you are at risk, talk to your GP. You can also contact the National Cancer Helpline 1800 200 700 for more information on being
Sunsmart and staying safe in the sun.
