Retinoblastoma refers to a relatively rare type of malignant tumor occurring in the retina of one or both eyes and, in some cases, spreading to the brain via the optic nerve. These types of tumors are often noticed by a white appearance of the pupil. Other associated symptoms include poor vision or blindness, reddened and painful eye, enlarged pupil, different-colored irises, and heterotropia (i.e., crossed eyes). Retinoblastomas generally occur prior to age 6, arising from abnormal cell growth in the developing retina, though adult cases have been documented.
