Voluntary breath-holding leading to bilateral subconjunctival haemorrhaging in a patient with schizophrenia.

Many forms of self-inflicted injury are seen in psychiatric patients. Some common forms reported in the literature include self-enucleation,1 genital self-mutilation,2 and amputation of a limb.3 Different aetiologies may contribute to the different types of self-inflicted injury, one such being acting-out of psychotic symptoms. This is an important area to explore as acting-out of psychotic symptoms may lead to injuries, sometimes fatal, to the patient or to others.
