Eye Cancers

Among children, retinoblastoma is the most common primary eye cancer; it affects children under age five. Malignant melanoma of the eye is found most frequently in adults; average age at diagnosis is 60 to 65 years old. Most eye cancers affect only one eye, but retinoblastoma involves both eyes in about one-third of cases. Retinoblastoma can occur in two forms an inherited form where there are often tumours in both eyes (bilateral) or sometimes only in one eye and a non-inherited form where there is a tumour in only one eye (unilateral). For children with only one eye affected, the treatment is usually surgery, and the eye is removed, unless the potential for vision is very good. By contrast, most children with retinoblastoma in both eyes will be treated with chemotherapy to shrink the tumors (called chemoreduction) and then the rest of the tumors is treated with some form of local treatment and radiation therapy. Surgery (removal of the eye) is reserved for the most advanced tumors.
