【摘要】 目的评价广角激光扫描血管造影技术在脉络膜黑色素瘤诊断中的应用价值。方法将24例临床诊断为脉络膜黑色素瘤的患者随机分为两组,分别应用激光扫描检眼镜的广角接触镜系统和非接触镜成像镜头对其行荧光素眼底血管造影和吲哚青绿血管造影的全景造影扫描,获得150°广角视野图像和30°视野图像资料,并对其成像质量进行综合评定。结果24例患者均获得满意的影像资料。广角成像系统提供了病变位置与其他解剖结构准确的毗邻关系,提供了病变的大小和造影过程中瘤体血管充盈情况的全面信息。同时将传统造影视野范围提高了3~5倍,有助于周边病变的筛查。结论广角激光扫描血管造影技术在脉络膜黑色素瘤诊断中有重要的应用价值。更多还原

【Abstract】 Objective To evaluate the application value of scanning laser angiography with a wide-field contact lens system in the diagnosis of choroidal melanoma. Methods Twenty-four patients with choroidal melanoma were randomly divided into two groups, who underwent fundus fluorescein angiography and indocyanine green angiography scanning with the wide-field contact and non-contact lens system respectively in order to acquire the 150° wide-field and 30° view image data. The quality of the images was comprehensively evaluated. Results Satisfying images were acquired from all of the 24 patients. Wide-field contact lens system indicated the accurate adjacent relation between the lesion position and the other dissection mechanisms, and also provided the general information about the size of the tumor and the perfusion of fluorescien or indocyanine green in the blood vessels. At the same time, it enlarged the view scope 3-5 times, which make for the screening of the peripheral lesions. Conclusions Scanning laser angiography with a wide-field contact lens system has important application value in the diagnosis of choroidal melanoma.更多还原
