Enucleation is the removal of the eye that leaves the eye muscles and remaining orbital contents intact. This type of ocular surgery is indicated for a number of ocular tumors, in eyes that have suffered severe trauma, and in eyes that are otherwise blind and painful. Auto-enucleation (oedipism) and other forms of serious self-inflicted eye injury are an extremely rare form of severe self-harm that usually results from mental illnesses involving acute psychosis. The name comes from Oedipus of Greek mythology, who gouged out his eyes in penance for having sex with his mother and killing his father. ==Classification== There are three types of eye removal: * Evisceration – removal of the iris, cornea, and internal eye contents, but with the sclera and attached extraocular muscles left behind * Enucleation of the eye - removal of the eyeball, but with the eyelids and adjacent structures of the eye socket remaining. An intraocular tumor excision requires an enucleation, not an evisceration. * Exenteration – removal of the contents of the eye socket, including the eyeball, fat, muscles, and other adjacent structures of the eye. The eyelids may also be removed in cases of cutaneous cancers and unrelenting infection. Exenteration is sometimes done together with maxillectomy (removal of the maxilla). 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「enucleation of the eye」の詳細全文を読む スポンサード リンク
