摘　　要：目的　了解眼前节常见肿瘤的超声生物显微镜表现特点。方法　应用超声生物显微镜对５５例常见眼前节肿瘤～虹膜囊肿、虹膜色素痣、睫状体肿瘤进行观察。结果　超声生物显微镜表现：虹膜囊肿为边界清晰的圆形或椭圆形囊样病变，内部为无回声区；虹膜色素痣为边界清晰的局限隆起，可为梭形、半球形等，内部回声均匀且与虹膜组织基本相同；睫状体肿瘤表现为睫状体局限隆起，可为半球形或蘑菇形，内部回声不均匀，前界回声强，后界回声弱，可伴有虹膜囊肿，继发脉络膜上腔渗漏。结论　超声生物显微镜对虹膜肿瘤可明确鉴别实性或囊性，睫状体肿瘤的基底部亦可详尽观察，超声生物显微镜是一种新的无创评估眼前节肿瘤的诊断方法。Objective To investigate the character of anterior segment tumor by ultrasound biomicroscopy(UBM).Methods UBM was used to diagnose 55 patients of anterior segment tumors,such as iris cyst,iris nevi and ciliary body tumors.Results UBM showed iris cyst was circular or ellipse with smooth surface and thin wall,but no reflectivify.iris nevus was of anteriorly convex shape in fusifarm or semicircles,its superficial layer can reflects as same as iris.Ciliary body tumors was of anteriorly convex shape in semicircle or mushroom,its reflectivity was not even,namely the reflectivity gets stronger near the probeand nice versa,and may be associated with iris cyst and superaciliary effusion.Conclusions Differentiation between solid and cystic lesion was easily achieved by UBM,the margins of ciliary body tumors could be more accurately defined UBM,proved a new noninvasive technique in the evaluation of anterior tumors.
