Postmortem endoscopy of the ocular fundus. A valuable tool in forensic postmortem practice.

摘要

Pathological changes of the ocular fundus in acute severe head or extracranial injury are difficult to document. In vivo examination usually has to be carried out under intensive care conditions. Postmortem ophthalmoscopy is usually impeded by rapid blurring of the cornea. Therefore, endoscopic fundal photography has been applied by using a pars plana approach during forensic postmortem procedures. This technique provides fundoscopic pictures of high quality as a valuable supplement for subsequent macro- and histopathological preparations and sections. Different patterns of fundoscopic findings seem to correspond to different types of injuries such as craniocerebral trauma, traumatic asphyxia and decompression sickness, and may allow some insight into the respective pathogenetic mechanism.
