| Outline of Final Research Achievements |
This study aimed to determine potential advantages and disadvantages of postmortem computed tomography (PMCT) for diagnosing peripapillary scleral hemorrhage. In four cases of intracranial injury, peripapillary scleral hemorrhage was detected in pathological examination. In one case, peripapillary scleral hemorrhage was detected using PMCT. However, we had one case of peripapillary scleral congestion, which we misdiagnosed as peripapillary scleral hemorrhage by using PMCT. It is difficult to diagnose peripapillary scleral hemorrhage by only using PMCT. Based on the manner of acquisition of the head injuries, the primary head impact locations, and the direction of acceleration and source of hemorrhage, we presume that peripapillary scleral hemorrhage is caused by traction of the optic nerve resulting from the brain being repositioned caudally in the intracranial space.
