Forensic aspects of ocular injury.

A case of homicidal stabbing resulting in bilateral penetrating ocular injuries is described. The case is noteworthy in that it highlights an unusual mechanism of death in homicidal stabbing. Disturbances in heart rhythm including asystole can be ascribed to the so-called oculocardiac or trigeminocardiac reflex. Although this phenomenon is well known to ophthalmologists, neurosurgeons, and anesthetists, it is much less familiar to forensic pathologists. This is a potential mechanism of death worthy of consideration in cases of sudden unexpected death occurring in the context of facial injury.
