Risk factors

Usually affects children


Retinoblastoma is more likely to develop in children with a family history of the condition.


Retinoblastoma can cause the eye to cross or turn outward. The most noticeable symptom is a change in the pupil’s color. It may appear white in reflected light, a phenomenon known as a cat’s eye reflex.


With early detection of retinoblastoma, treatment can be highly effective. Treatment options include medication, radiation therapy, and heat, freezing, or laser treatments. More than 90 percent of children survive and eyes may be saved through treatment. In extreme cases, the affected eye is removed.
