What is it?
Understanding of Retinoblastoma has grown in recent years and is now virtually 100% curable.
Retinoblastoma develops in the light-sensitive lining of the eye, called the retina and can either be unilateral (affects one eye) or bilateral (affecting both eyes).
Around 2 in 5 children have the heritable form of retinoblastoma, allowing the abnormal gene to develop into a tumour.
Symptoms can include a white pupil that doesn’t reflect light, a squint, a painful red eye or in older children, deteriorating vision.
