Enucleation of the eye
Enucleation of the Eye
Enucleation of the eye (pronunciation: /ɪˌnjuːklɪˈeɪʃən ɒv ðiː aɪ/) is a medical procedure that involves the removal of the eye that is irreversibly damaged or diseased, leaving the eye muscles and other contents of the eye socket intact.
Etymology
The term "enucleation" is derived from the Latin word "enucleare", which means to remove the kernel of (a nut). In medical terminology, it refers to the removal of an organ or other body part in its entirety.
Procedure
Enucleation is typically performed under general anesthesia. The surgeon makes an incision in the conjunctiva, the clear tissue covering the white part of the eye, and then carefully separates the eye from the surrounding muscles, connective tissue, and the optic nerve. Once the eye is removed, an orbital implant is usually inserted in the empty socket to replace the volume of the removed eye and to provide a base for the artificial eye.
