目前已应用放疗、光凝、冷凝、化疗、免疫疗法等治疗视网膜母细胞瘤。过去仅用眼底镜直接观察治疗效果。作者除了应用限底镜直接观察外,还应用了荧光血管造影。特别在怀疑有复发时,荧光血管造影可以明确诊断。作者对13例14眼进行了治疗前、后的荧光血管造影检查。根据肿瘤的大小,作者将14眼内的31个肿瘤分成4组来观察各组的荧光表现。一、治疗前的眼底荧光血管造影所见第一组:6个肿瘤。肿瘤小于0.5视盘大小。荧光造影早期相显示毛细血管轻度扩张,肿瘤内有极少量荧光滞留。晚期相显示肿瘤血管被脉络膜背景荧光所遮挡。第二组:5个肿瘤。肿瘤大约1个视盘大
At present, radiotherapy, photocoagulation, condensation, chemotherapy and immunotherapy have been used to treat retinoblastoma. In the past, the ophthalmoscope was used to directly observe the therapeutic effect. In addition to using the endoscopic direct observation, the author also applied fluorescent angiography. Fluorescein angiography can confirm the diagnosis, especially when it is suspected of recurrence. The authors examined 13 cases of 14 eyes before and after treatment with fluorescein angiography. According to the size of the tumor, the authors divided the 31 tumors in 14 eyes into 4 groups to observe the fluorescent appearance of each group. First, before treatment of fundus fluorescein angiography seen in the first group: 6 tumors. Tumors less than 0.5 disc size. Fluorescent angiography early phase showed mild dilation of capillaries, there is a very small amount of fluorescence in the tumor retention. The late phase shows tumor blood vessels blocked by the choroidal background fluorescence. The second group: 5 tumors. Approximately 1 tumor in the optic disc
