Retinoblastoma

Retinoblastoma is a cancer of the eye. It is a relatively rare cancer, but it accounts for approximately 5% of blindness in children.

Most cases of Retinoblastoma occur in children under the age of five, although it can affect children of any age.

Retinoblastoma occurs in the retina, which is the light-sensitive lining of the eye and there are two forms:

• an inherited form where there are often tumours in both eyes (bilateral) or sometimes only in one eye
• a non-inherited form where there is a tumour in only one eye (unilateral)
