虹膜睫状体肿物的超声生物显微镜检查

目的 探讨超声生物显微镜（ultrasound biomicroscope, UBM）在虹膜睫状体肿物诊断治疗中的应用价值。 方法 对34例怀疑虹膜睫状体肿物的患者的35只患眼以UBM（Humphrey 840型，扫描频率50 MHz，扫描深度范围5 mm×5 mm）检查，17例行眼科专用B型超声或彩色超声检查,5例行CT检查，并对21只患眼手术切除的病变组织作病理组织学检查。 结果 35只患眼虹膜睫状体肿物可被UBM发现并确定其起始部位。其中UBM诊断前房虹膜囊肿6只眼,病理诊断虹膜植入性囊肿3只眼;UBM诊断虹膜后囊肿13例14只眼,病理诊断虹膜后囊肿3只眼;UBM诊断虹膜睫状体肿物15只眼,病理诊断睫状体黑瘤7只眼，虹膜睫状体转移癌4只眼，睫状体神经鞘瘤1只眼，平滑肌瘤1只眼，睫状体黑色素细胞瘤1只眼，色素上皮腺癌1只眼。 结论 UBM检查能发现虹膜睫状体部位的肿瘤并提供其大小、范围和结构信息，有助于了解病变的位置、性质，有助于手术设计和肿物的完全切除。 (中华眼底病杂志, 2002, 18: 128-130)

Ultrasound biomicroscopy in 34 cases of iris and ciliary tumor

Objective To probe the significance of application of ultrasound biomicroscopy (UBM) in the diagnosis and management of the iris and ciliary tumors. Methods UBM (Mode 840, Humphrey, 50 MHz 5 mm×5 mm) was done in 34 cases (35 eyes) of iris and ciliary body tumors, and some of the affected eyes underwent B-scan or Doppler ultrasound and CT scan. Histopathological examination of the resected tumor tissues was performed in 21 eyes of the operation. Results Among this series of 35 eyes with iris and ciliary body tumors detected by UBM, the characteristics of locality and solidity of the tumors, i,e., anterior chamber in plantation cyst, cyst behind the iris, and solid tumors of iris and ciliary body, of 21 eyes undergone surgical treatment revealed the same results both in UBM and histopathological examinations. Conclusion UBM can supply precise informations in diagnosis and treatment of tumors of iris and ciliary body. (Chin J Ocul Fundus Dis, 2002, 18: 128-130)
