Tests and procedures used to diagnose retinoblastoma include:
- Eye exam. Your eye doctor will conduct an eye exam to determine what's causing your child's signs and symptoms. For a more thorough exam, the doctor may recommend using anesthetics to keep your child still.
- Imaging tests. Scans and other imaging tests can help your child's doctor determine whether retinoblastoma has grown to affect other structures around the eye. Imaging tests may include ultrasound, computerized tomography (CT) scan and magnetic resonance imaging (MRI), among others.
- Consulting with other doctors. Your child's doctor may refer you to other specialists, such as a doctor who specializes in treating cancer (oncologist), a genetic counselor or a surgeon.
