Retinoblastoma
Background
Retinoblastoma: 13q Deletion syndrome
Retinoblastoma is a malignant tumour which develops at the back of the eye. It originates in the cells of the retina, the light sensitive lining of the eye.
It affects babies and young children and is very rare after the age of five years. Retinoblastoma may be unilateral (affecting one eye) or bilateral (both eyes involved). The unilateral form is more common and accounts for approximately 60 per cent of all cases.
