Retinoblastoma (Eye Tumor)

What is retinoblastoma?

Retinoblastoma is a cancerous tumor that grows in the retina, the light-sensing part of the eye that sends the images we see to the brain. This childhood cancer, which occurs most often in children under five, can be present in one or both eyes. 

How is retinoblastoma diagnosed?

In diagnosing retinoblastoma, our pediatric ophthamologist will examine the retina by dilating the eye, and also order imaging tests, like an ultrasound of the eye, a computerized tomography (CT) scan, or magnetic resonance imaging (MRI), as well as blood tests.

How is retinoblastoma treated?

If tests reveal that a retinoblastoma might be present, our doctors will work together with Nemours pediatric oncologists (cancer doctors) to look for any other signs of the cancer in the body, and determine the disease stage and best course of treatment.

At Nemours, we know that the discovery of a childhood cancer like retinoblastoma is overwhelming. We promise to give you and your child the resources you need to make informed decisions, to answer all your questions, and to help you cope every step of the way. 

You should also know that majority of children treated for retinoblastoma go on to lead normal lives ― and more than 80% of them will retain 20/20 vision.
