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 sustained severe trauma, and in eyes that are otherwise blind and painful.

An enucleation is the removal of the eye leaving the eye muscles and remaining orbital contents intact. [37] An evisceration is the removal of the eye's contents, leaving the scleral shell intact. Usually performed to reduce pain in a blind eye. [38]
Evisceration differs from enucleation, as enucleation involves the removal of the scleral shell as well. Evisceration was first described by Bear in 1817 as an experimental treatment for expulsive hemorrhage, and with the advent of general anesthesia in the 1840’s the procedure was refined and ocular implants were developed.
Autoenucleation, also known as oedipism, is the self-inflicted enucleation (removal) of the eye. It is considered a form of self-mutilation and is normally caused by psychosis, paranoid delusions or drugs. [1] Between 1968 and 2018, there were more than 50 documented cases of "complete or partial self-enucleation in English medical journals". [2]

Enucleation of an eye and, similarly, retinal damage, leads to a cascade of events in the cortical areas receiving visual input. Cortical GABAergic (GABA: Gamma-aminobutyric acid ) inhibition decreases, and cortical glutamatergic excitation increases, followed by increased visual excitability or even spontaneous activity in the visual cortex ...
