The authors present a case of bilateral retinoblastoma occured in a six months old baby. The right eye, the advanced, was enucleated immediately and the left eye was treated with x-ray radiation giving 5,400r (tumor dose) in four weeks. A cataract developed in five years after the radiation therapy, which masked the pictures of the fundus and was extracted intracapsularily using alpha-chymotripsin. After the surgery, repeated funduscopy revealed no definite signs of recurrence.
