Enucleation refers to the surgical removal of an eye. This procedure is generally recommended only when there is no other choice. Enucleation is performed for several different reasons: to remove a malignant tumor that has developed within the eye; to alleviate intolerable pain in a blind eye affected by a condition such as uncontrollable glaucoma; or to reduce the risk of "sympathetic" inflammation of the remaining eye when one eye has been severely injured and blinded.
