Retinoblastoma, a type of eye cancer, can occur at any age. However, it most commonly affects children younger than five years of age.
Symptoms can include the following:
- The pupil of the eye appears white instead of red when light shines into it. This may be seen in flash photographs of the child.
- Eyes appear to be looking in different directions (crossed eyes).
- Pain or redness in the eye.
Keep in mind that these are not always sure signs of retinoblastoma. They may be caused by other, less serious health problems. To make a diagnosis, your healthcare provider may use a number of tests, including:
- Eye exam with dilated pupil
- CT (computed tomography) scan
- MRI (magnetic resonance imaging).
This type of cancer is usually diagnosed without a biopsy.
