摘　　要：目的探讨不同类型睫状体肿瘤的超声生物显微镜影像学改变,为此类疾病的诊断和鉴别诊断提供临床依据方法 2002年7月～2005年7月经病理证实的睫状体肿瘤患者9例9眼,其中恶性黑色素瘤5例,黑包素细胞瘤2例,髓上皮瘤1例,转移癌1例所有病例术前行超声生物显微镜影像(ultrasoundbiomicroscopy,UBM)检查,对肿瘤采集射状切面和横断面图像结果睫状体恶性黑色素瘤的 UBM 影像均呈近似或典型"蕈佯"外观伴声衰减,基底部存在大小不等的无回声区。黑色素细胞瘤1例与黑色素瘤表现类似,另1例为圆顶状中高回声肿块伴轻度声衰减,1例转移癌呈类圆形低到中等回声肿块伴有卫星灶。1例髓上皮瘤呈睫状冠部中高回声连续性肿块,伴多发性囊样无回声区结论睫状体肿瘤的 UBM 影像特征依肿瘤性质不同而各具特征,UBM 能够对睫状体肿瘤的诊断和鉴别诊断提供有价值的临床依据。Purpose To evaluate the diagnostic value of ultrasound biomicroscopy （UBM） for ciliary body tumors. Methods 9 eyes of 9 eases with ciliary body tumors proved by pathology were examined with ultrosound biomicroscopy （UBM）. Of the 9 eases, 5 were malignant melanoma, 2 melanoeytoma, 1 medulloepithelioma and 1 was metastasis. For each case, radial and transversal sections of the tumor were captured by UBM. Results UBM examination of ciliary body melanoma showed mushroom-shaped mass appearance with echo attenuation. Anechoic spaces of different sizes could be seen in the base of tumour. One ease of melanocytoma had similar imaging as the cases of melanoma, while the other case of melanocytoma represented as a doom shaped mass with medium to high reflectivity and mild echo attenuation. The case of metastasis showed a round mass with low to medium refleetivity and multifocal nodules around the tumor. The case of medulloepithelioma represented as a continuous mass with medium to high internal reflectivity and cystoid anechoic spaces in the margin area. Conclusion The UBM features of ciliary body tumors are different according to different pathological types of tumors. UBM examination can provide valuable and helpful evidence in the diagnosis of ciliary body tumors. （Chin J Ophthalmol and Otorhinolaryngology, 2006,6 ： 303 - 305 ）
