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] According to a 2012 study published in the British Journal of Ophthalmology, self-enucleation was previously "considered to be the result of psycho-sexual conflicts" even if psychosis is a more likely cause.^[3]

A famous case of autoenucleation can be found in Greek mythology: Oedipus, according to Sophocles's tragedy Oedipus Rex, gouged his own eyes out after discovering he had married his mother.

On February 6, 2018, a 20-year old American, Kaylee Muthart, received national attention after she gouged both her eyes out while high on methamphetamine, believing that "sacrificing her eyes [would] save the world".^[9] The incident left Muthart permanently blind, though she later said "I'm happier now than I was before all this happened".^[10][11][12]
