Autoenucleation
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. Between 1968 and 2018, there were more than 50 documented cases of "complete or partial self-enucleation in English medical journals". 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.
