Children with retinoblastoma often experience the following symptoms or signs. Symptoms are changes that you can feel in your body. Signs are changes in something measured, like by taking your blood pressure or doing a lab test. Together, symptoms and signs can help describe a medical problem. Sometimes, children with retinoblastoma do not have any of the symptoms and signs described below. Or, the cause of a symptom or sign may be a medical condition that is not cancer. Sometimes, a doctor finds retinoblastoma during a routine well-baby examination. Most often, however, parents notice symptoms or signs such as:

• A pupil that looks white, instead of the normal black

• A crossed eye, which is an eye looking either toward the ear or toward the nose

• Poor vision

• A red, painful-looking eye

• An enlarged pupil

• Different-colored irises

If you are concerned about any changes you notice, please talk with your child’s doctor. Your child's doctor will ask how long and how often your child has been experiencing the symptom(s), in addition to other questions. This is to help figure out the cause of the problem, called a diagnosis.

If cancer is diagnosed, relieving symptoms remains an important part of your child’s cancer care and treatment. Managing symptoms may also be called "palliative care" or "supportive care." It is often started soon after diagnosis and continued throughout treatment. Be sure to talk with your child's health care team about the symptoms your child experiences, including any new symptoms or a change in symptoms.
