目的对于SD-OCT诊断明确的玻璃体视盘牵拉(VPT)患者行10MHz B型超声检查,并对比分析玻璃体视盘牵拉在SD-OCT及10MHz B型超声的特点,提高该类疾病的临床诊断率.方法临床病例对照分析研究.对2009年6月至2012年6月在河北医科大学第二医院眼科进行SD-OCT已明确VPT诊断的58例患者60只眼,做10 MHz B型超声检查,总结该类病变在二者的特征,并予以比较.结果重度:SD-OCT示玻璃体后脱离,于盘周与视盘相连,视盘受牵拉,盘周视网膜神经上皮层浅脱离;相应B型超声示“V”字形回声带,顶端与视盘相连前突于玻璃体腔,回声带与球后壁存在液性暗区.中度:SD-OCT示玻璃体后脱离,视盘受牵拉隆起,但盘周无神经上皮层浅脱离;B型超声示“一”字形回声带与视盘相连,回声带与球后壁间液性暗区较窄.轻度:SD-OCT示玻璃体后脱离,于盘周与视盘相连,但视盘形态正常;B型超声示视盘前“一”字形回声带,回声带与球后壁间无明显液性暗区.结论 SD-OCT可以实现对玻璃体视盘牵拉病变的明确诊断,同时该类病变在10 MHzB型超声上也存在特征性的表现,因此虽然10 MHz B型超声的分辨率有限,但在玻璃体视盘牵拉病变诊断中仍有一定应用价值.

Objective To compare the differences of spectral-domain optical coherence tomography (SD-OCT) and B-ultrasonography in the diagnosis of vitreopapillary traction (VPT),and to investigate the similarity between the two measures.Methods Collected B-ultrasound images and SD-OCT images of 60 eyes from 58 subjects with VPT,diagnosed by SD-OCT,and summarized the features successively.Results Accompanied by posterior vitreous detachment,the typical characteristics of VPT could be depicted in three forms:papilla tracted forward into vitreous cavity with the edema of optic disc,papilla dragged forward without edema of optic disc,and normal papilla.Accordingly,they presented themselves ultrasonographically as V-shape echogenic band with the peak attached to papilla and obvious liquid anechoic area,linear shape echogenic band with extremely narrow liquid anechoic area,and linear echogenic band with hardly any liquid anechoic area.Conclusions Diagnosed by SD-OCT precisely,vitreopapillary traction presents several B-ultrasonographical characteristics.With limited resolution,B-ultrasound still possesses diagnostic significance in less developed suburbs.
