Diagnosis

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 and magnetic resonance imaging (MRI), among others.
