Who Gets Retinoblastoma?
Retinoblastoma occurs most often in children 5 years and under. It rarely occurs
in adults. Between 200 and 300 children are diagnosed with retinoblastoma each
year, affecting one in every 20,000. About 40% of all cases of retinoblastoma
are inherited, meaning the cancer is passed on from parent to child. Retinoblastoma
occurs about 75% of the time in one eye, and 25% of the time in both eyes.
What Are the Symptoms of Retinoblastoma?
Symptoms of retinoblastoma include:
- A pupil that appears white when light is shone into it, called leucocoria,
may mean that a retinal tumor is present. Blood vessels in the back of the
eye will normally reflect red.
- The eyes may not move or focus in the same
direction.
- Eye pain.
- The pupil is constantly dilated.
- Red eye(s).
