A few rare conditions can cause the symptoms and signs listed below, not just cancer. If your child has any of these symptoms or signs and you are worried, visit your child’s doctor. The earlier cancer is found, the better.

Symptoms of retinoblastoma may include:

  • a pupil (the black part in the middle of the eye) that appears white instead of red when a light is shone into it (e.g. in a photograph)
  • a red or painful eye
  • an eye that is larger than usual
  • cloudiness in the iris (the coloured part of the eye) and the pupil
  • eyes that seem to be looking in different directions (also called 'lazy or crossed eye').
