眼底荧光血管造影是检查脉络膜血管瘤的有效方法。但有时也可出现与恶性黑色素瘤相似的荧光像,给诊断带来困难。作者以球后注射荧光素眼底造影法或称化学性巩膜透照法(chemicaltrans-illumination,CTI)检查一48岁男性患者,并与常用方法作了比较。该患者有原因不明的多发性神经炎,当时曾怀疑眼底有转移性肿瘤。左眼视乳头颞上方有一6×4 PD、隆起7屈光度之白色肿物,卵圆形,表面光滑,下缘达黄斑。其部分下缘有色素沉着。肿物处未见视网膜脱离,下方周边部有轻度脱离。先作一般眼底荧光血管造影,随后又作了CTI检查。最终因视力显著障碍,视网膜电图波形消失而摘除眼球,病理证实为孤立的脉络膜血管 Fundus fluorescein angiography is an effective method to examine choroidal hemangiomas. But sometimes similar to the appearance of malignant melanoma fluorescence images, to the diagnosis of difficulties. The authors examined a 48-year-old man with a post-injection fluorescein fundus or chemicaltrans-illumination (CTI) and compared it to the usual methods. The patient had unexplained polyneuritis, at which time he had suspected that the fundus had a metastatic tumor. The left temporal papilla had a 6 × 4 PD above the temporal region and a white mass of 7 diopters raised, ovoid, smooth, and the lower margin reaching the macula. Part of the lower edge of pigmentation. No retinal detachment at the detachment, the lower part of the periphery there is a slight detachment. First for general fundus fluorescein angiography, followed by another CTI examination. Eventually due to significant visual impairment, disappearance of the electroretinogram waveform removed the eye, the pathology confirmed as isolated choroidal blood vessels
