B型超声在伏洛特-小柳原田综合征诊断中的临床应用

Clinical application of B-mode ultrasound in diagnosis of Vogt-Koyanagi-Harada syndrome

目的总结分析伏洛特-小柳原田综合征(VKH)的B型超声特征,探讨B型超声诊断VKH病的临床价值。方法应用B型超声检查分析18例(36只眼)VKH患者的病变位置、形状、其内回声及声衰减等特点。结果VKH综合征声像图表现为:脉络膜弥散性水肿、增厚;呈高回声或稍高回声的患者多已累及睫状体;合并浆液性视网膜脱离者,可见玻璃体腔内与视盘相连的强回声光带,视网膜下积液呈点状回声;玻璃体腔炎性细胞表现为轻至中度的玻璃体腔内点状回声。结论B型超声对于屈光介质混浊,不能行眼底血管荧光造影的患者有较好的临床诊断价值,是诊断VKH综合征有效的检查手段。

Objective To analyze the characteristics of Vogt-Koyanagi-Harada syndrome by B-mode ultrasound, and to explore the clinical value of B-Mode ultrasound in diagnosis of VKH. Methods Eighteen patients with VKH were enrolled in this study, and the position, shape, internal echo and attenuation of sound of lesions were analyzed by B-mode ultrasound. Results The sonogram appearances of VKH were diffuse edema and thickening in chorioid, the ciliary body was involved in patients with mild to moderate echo. The strong echo light pattern which connected to optic disc was found in vitreous cavity in patients with serous detachment of retina, the subretinal dropsy was spot echo. The appearance of inflammatory cells in vitreous cavity showed mild to moderate spot-echo. Conclusion B-mode ultrasound has good clinical value in diagnosis of patients with cloudy VKH,and it is an effective method in diagnosis of VKH.
