Retinoblastoma, which occurs most commonly in children under the age of 5, is a cancerous tumor that grows in the retina, the light-sensing part of the eye that sends the images that we see to the brain. In children, retinoblastoma can be present in one or both eyes.

How is retinoblastoma diagnosed?

In diagnosing retinoblastoma in children, our pediatric ophthalmologist 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.
