According to the Mayo Clinic, Retinoblastoma is a rare cancerous tumor of the retina caused by a gene mutation. It generally affects children younger than 6 years old. This gene mutation may run in families or it may occur in a child with no family history of the disease.
Retinoblastoma may affect one or both eyes. Children with this disease often have a white pupil due to the light-colored tumor inside the eye. They may also develop crossed eyes or wandering eyes.
Children who develop retinoblastoma — especially the hereditary type — have an increased risk of developing other types of cancer later in life. Children who have retinoblastoma in only one eye are also at increased risk of developing the disease in the other eye and require frequent eye exams even after treatment.
Treatment options are similar for other forms of eye cancer.
