目的 对SD-OCT诊断明确的玻璃体黄斑牵拉性病变进行10 MHz B型超声检查,利用SD-OCT的诊断结果指导并探讨B型超声对该类病变的临床诊断价值.方法 对经SD-OCT检查确诊的玻璃体黄斑牵拉性病变60例60只眼,进行10 MHz B型超声检查,分析总结该类病变在B型超声的影像学特征.结果 SD-OCT示玻璃体后脱离,黄斑受牵拉隆起,“山峰”样突入玻璃体腔；B型超声示“V”字形带状回声,“V”字尖端与黄斑相连,但突出于球壁.SD-OCT示玻璃体后脱离,黄斑受牵拉隆起,中心凹变平坦；B型超声示“一”字形带状回声,与球壁间有极窄的液性暗区,“一”字中央与黄斑相连.SD-OCT示玻璃体后脱离,黄斑受牵拉,但中心凹形态基本正常；B型超声示“一”字形带状回声,与球壁间几乎没有液性暗区.结论 SD-OCT能够明确诊断玻璃体黄斑牵拉性病变,10 MHzB型超声对该类病变识别能力稍差,但仍有特征性表现,虽然传统的10 MHz B型超声对上述病变分辨率低,但因仪器价格低廉,且不受被检眼屈光间质的影响,因此仍有一定的临床应用价值.
目的 對SD-OCT診斷明確的玻璃體黃斑牽拉性病變進行10 MHz B型超聲檢查,利用SD-OCT的診斷結果指導併探討B型超聲對該類病變的臨床診斷價值.方法 對經SD-OCT檢查確診的玻璃體黃斑牽拉性病變60例60隻眼,進行10 MHz B型超聲檢查,分析總結該類病變在B型超聲的影像學特徵.結果 SD-OCT示玻璃體後脫離,黃斑受牽拉隆起,“山峰”樣突入玻璃體腔；B型超聲示“V”字形帶狀迴聲,“V”字尖耑與黃斑相連,但突齣于毬壁.SD-OCT示玻璃體後脫離,黃斑受牽拉隆起,中心凹變平坦；B型超聲示“一”字形帶狀迴聲,與毬壁間有極窄的液性暗區,“一”字中央與黃斑相連.SD-OCT示玻璃體後脫離,黃斑受牽拉,但中心凹形態基本正常；B型超聲示“一”字形帶狀迴聲,與毬壁間幾乎沒有液性暗區.結論 SD-OCT能夠明確診斷玻璃體黃斑牽拉性病變,10 MHzB型超聲對該類病變識彆能力稍差,但仍有特徵性錶現,雖然傳統的10 MHz B型超聲對上述病變分辨率低,但因儀器價格低廉,且不受被檢眼屈光間質的影響,因此仍有一定的臨床應用價值.

Objective To compare differences between SD-OCT and B-ultrasound in the diagnosis of VMT,and to investigate the clinical diagnostic significance of B-ultrasonography (10MHz),under the guide of SD-OCT.Methods B-ultrasound images of 60 eyes from 60 subjects with VMT were collected,diagnosed through SD-OCT,to summarize the B-ultrasonograghical characteristics of VMT.Results Typical VMT showed itself in three forms:macula tracted forward into vitreous cavity hill-like,flattened central fovea by the drag of vitreous with posterior detachment,and normal central fovea,accompanied by posterior vitreous detachment on SD-OCT,and they presented themselves ultrasonographically as V-shape echogenic band with the apex attached to macula,linear shape echogenic band with extremely narrow liquid anechoic area between the echogenic band and posterior wall,and linear shape echogenic band with hardly any liquid anechoic area.Conclusions Compared with the limited competence of B-ultrasound,SD-OCT can precisely diagnose VMT.But B-ultrasound still has some specific characteristics; regardless of the refracting media,it still can provide valuable information about the fundus,and it therefore holds certain clinical worth,when SD-OCT isn't available.
