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(Humphrey84 0型 ,扫描频率 5 0 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 2 1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。
Objective To investigate the value of ultrasound biomicroscope (UBM) in the diagnosis and treatment of iridocyclitis. Methods Totally 35 eyes of 34 patients with suspected iris ciliary body mass were examined by UBM (Humphrey type 84 0, scan frequency 50 MHz, scan depth range 5 mm × 5 mm). Seventeen patients underwent ophthalmologic special type B ultrasound Or color sonography, CT scan was performed in 5 cases, and histopathological examination was performed on 21 diseased tissues resected by eyes. Results 35 patients with iris ciliary body tumor can be found by UBM and determine the initial site. UBM diagnosis of anterior chamber iris cysts in 6 eyes, pathological diagnosis of iris implantable cysts in 3 eyes; UBM diagnosis of posterior iridocysts in 13 cases, pathological diagnosis of posterior iridocyst in 3 eyes; UBM diagnosis of iris ciliary body mass 15 eyes, pathological diagnosis of ciliary body melanoma in 7 eyes, iridociliary metastasis in 4 eyes, ciliary nerve schwannoma in 1 eye, leiomyoma 1 eye, ciliary body melanocytoma 1 Eye, pigmented epithelial adenocarcinoma 1 eye. Conclusion The UBM examination can detect the tumor in the iris ciliary body and provide information on the size, range and structure of the tumor. It is helpful to understand the location and nature of the lesion and to facilitate the surgical design and the complete resection of the tumor.
