Pathogenesis of conjunctival petechiae

Conjunctival petechiae from 15 cases (cause of death: different natural and unnatural) were analysed using confocal laser scanning microscopy (CLSM) in order to visualize the kind of the damage within the vessel wall (diapedesis versus rhexis). The pathomorphological findings with multiple ruptures of vessels appearing to be filled to bursting point define the conjunctival petechiae as a rhexis-haemorrhage.
