How is retinoblastoma diagnosed?

An eye exam and imaging test given by an ophthalmologist (an eye doctor) can diagnose the condition.

If retinoblastoma is suspected, the child is usually referred to an ophthalmologist with interest and expertise in this condition. The ophthalmologist will need to examine the eye using special equipment to see the retina. Other tests might be conducted to determine the stage of the retinoblastoma, or how far it has spread. These tests, often coordinated by a collaborating pediatric oncologist, may include ultrasound, MRI scans, CT scans, bone scans, spinal tap, and bone marrow tests.
