| Outline of Final Research Achievements |
The aim of this study is to examine the potential benefit of postmortem computed tomography (PMCT) for intraocular diagnosis.
We could detect suprachoroidal hemorrhage (SCH), calcified senile scleral plaques, silicone oil-injected eye, and phthisis bulbi by using PMCT. Conversely, we could not detect postmortem retinal folds, vitreous hemorrhage, or proliferative vitreoretinopathy by using PMCT. The most frequently finding in the eyes of cadavers is retinal fold. However, we were not able to detect postmortem retinal folds using PMCT. We attribute this disparity to both the limited resolution of CT scans and the characteristics of the postmortem retinal folds, which are too narrow to accumulate subretinal fluid. In all cases, PMCT could detect SCH. The increase in intrathoracic pressure caused by dyspnea or chest compression was considered responsible for the onset of SCH in all cases. Therefore, PMCT might assist with the differential diagnosis of traumatic asphyxiation by SCH.
