目的：探讨眼科B型超声检查在诊断玻璃体后脱离(posterior vitreous detachment，PVD)中的应用价值。
方法：选取2011-09/2012-09来我院进行治疗的PVD患者305例506眼，应用B型超声进行检查和分析。
结果：选取506眼中共计179眼(35.4%)为不完全PVD，327眼(64.6%)为完全PVD。其中有61眼(12.1%)出现少量玻璃体出血，经检查26眼(5.1%)为视网膜裂孔，裂孔周边激光光凝治疗后痊愈。
结论：眼科B型超声检查可以准确诊断PVD，同时具有无创和快捷等特点，值得在临床上推广。

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.
