Oedipism or self-enucleation is a rare form of self-mutilation, and most often described in acutely psychotic patients, who have religious or sexual delusions.
A 47-year-old Chinese man with a ...history of chronic schizophrenia enucleated his own left eye and mutilated his right eye. The reason for his behaviour was unknown. The history and legends surrounding autoenucleation and the medical literature are reviewed.
The patient was managed jointly with the psychiatrist. He suffered extensive injury to his right eye, resulting in loss of vision.
The management of Oedipism requires close cooperation between ophthalmologists and psychiatrists. Precautions must be taken to prevent repeated attempts or other self-mutilatory behaviour.
A mild electric shock applied to the lower lip was used to elicit reliable evoked potentials from the trigeminal nerve in 50 normal adults who ranged in age from 20 to 69 years. The waveforms were ...morphologically similar to those observed with invasive procedures. No substantial effects for subject age, side of stimulation, or recording electrode were obtained for any of the individual trigeminal evoked potential amplitudes or latencies. Female subjects tended to have somewhat larger amplitudes and shorter latencies than male subjects. The results suggest that non-invasive procedures produce reliable evoked potential measures of trigeminal nerve function for patients of all ages.
