Abstract
- The objective of this study was to ascertain the elationship between the various ocular traumas and the change of pulsatile ocular blood flow[POBF] measured with Ocular Blood Flow Tonograph[OBF Laboratories, UK Ltd.]. We tested POBF with Ocular Blood Flow Tonograph 3 times repeatedly within 48 hours after trauma in the 33 ocular trauma patients.In all the trauma eyes, heart rate[HR]and intraocular pressure[IOP]were higher and pulse amplitude [PA], pulse volume[PV], POBF were lower than in all the fellow eyes.In the hyphema group, HR, IOP, PA, PV, POBF were higher, especially IOP and OBF%S.D.were statically significant, than in non-hyphema group.In the orbital fracture group, only POBF and OBF%S.D.were higher than those of in non-fracture group. Therefore, these results show the change of POBF after various ocularinjuries in the ocular trauma patients.The further studies to follow up the serial change of POBF are necessary.
