Abstract:
Objective To discuss the diagnosis characteristics and clinical value of posterior vitreous detachment (PVD) by color Doppler flow imaging(CDFI). Methods One thousand and two cases were examed by CDFI for the diagnosis standard and property of PVD. Results Typical acoustic properties of PVD: the B scan may show a very fluid thick line. There were two types complete PVD and part PVD based on the vitreous separated from the optic nerve. Kinetic echography typically showed a very fluid, undulating after movement of the completely PVD. Part PVD had more than one dot with attachments to the retina and less mobile than complete PVD. There was not blood flow signal on the PVD by CDFI. Conclusions Ultrasonography for PVD not only exactitudes,but also provides foundation for clinic.
