AIM: To investigate the utility of ultrasound in the diagnosis of posterior vitreous detachment(PVD).

METHODS: From September 2011 to September 2012, 506 eyes of 305 cases(male 191, female 114)of PVD patients in our hospital were checked and analyzed with ultrasound.

RESULTS: Totally, 179 eyes were diagnosed as partial PVD, the proportion was 35.4%. And 327 eyes were diagnosed as complete PVD, the proportion was 64.6%. Among the 61 eyes(12.1%)with a small amount of hemorrhage of vitreous humor,retinal breaks of 26 eyes(5.1%)were founded. Given the photocoagulation nicely heal to the breaks and then recovered.

CONCLUSION:Ultrasonography can accurately diagnose PVD. It has non-invasive,convenience, and other characteristics, and it is worthy of clinical popularization.
