眼内肿瘤的彩色超声多普勒诊断分析

目的研究眼内肿瘤的彩色超声多普勒诊断特征，为鉴别诊断提供依据。方法应用彩色超声多普勒诊断仪对９２例（１０５只眼）眼内肿瘤进行检查，观察各种肿瘤的血流特征，并测定病变内血管的血流参数。用ＳＡＳ软件对测定结果进行统计学分析。结果视网膜母细胞瘤、脉络膜黑色素瘤、脉络膜血管瘤、视盘血管瘤、脉络膜转移癌，Ｃｏａｔｓ病及原始玻璃体增生症（ｐｅｒｓｉｓｔｅｎｔｈｙｐｅｒｐｌａｓｔｉｃｐｒｉ－ｍａｒｙｖｉｔｒｅｏｕｓ，ＰＨＰＶ）的病变上均可发现血流信号；而脉络膜骨瘤和视乳头黑色素细胞瘤的病变内无血流信号。脉络膜黑色素瘤的视网膜中央动脉和脉络膜血管瘤的眼动脉、视网膜中央动脉及睫状后短动脉的血流参数均较正常值下降（Ｐ＜０．０５）；而脉络膜黑色素瘤与脉络膜血管瘤比较，睫状后短动脉的血流速度，前者明显高于后者（Ｐ＜０．０５）。结论彩色超声多普勒对眼内肿瘤的诊断及鉴别诊断有重要价值。

Color Doppler imaging diagnosis of ocular tumor

Objective To study the characteristics of color Doppler imaging (CDI) of ocular tumors for the diagnosis and differential diagnosis of the tumors. Methods 92 cases with ocular tumor (105 eyes) were examined by CDI to observe the vasculature of ocular tumors, and the various parameters of blood vessels and blood flow in the lesions were measured. SAS software was used to analyze the results.Results Blood flow signal can be found in retinoblastoma, melanoma of choroid, angioma of choroid, angioma of optic nerve papilla, Coats disease, persistent hyperplastic primary vitreous (PHPV) and metastatic tumors of choroid, but we can not find any blood flow signal in choroid osteoma and melanocytoma of optic nerve papilla. The blood flow parameters of central retinal artery in choroidal melanoma and that of ophthalmic artery, central retinal artery and posterior ciliary artery in angioma of choroid are lower than normal ( P <0.05). In the comparison of the blood velocity in the posterior ciliary artery between choroidal melanoma and choroidal angioma, it was found that the former is much higher than the latter ( P <0.05). Conclusion CDI is very important in the diagnosis and differential diagnosis of ocular tumors.
