作者以荧光素血管造影术研究了3例色素性虹膜肿瘤:1例黑色素细胞瘤遮蔽荧光;2例恶性黑色素瘤在动脉期之很早期就有荧光渗漏。作者推荐在色素性虹膜肿瘤患者行荧光素血管造影作为诊断依据之一。虹膜和睫状体的黑色素瘤仅占眼内原发肿瘤的一小部分,当色素性病变出现在虹膜或前房角时,须考虑虹膜痣,黑色素瘤、囊肿和色素细胞 The authors studied three pigmented iris neoplasms with fluorescein angiography: one case of melanocytoma masked fluorescence; two cases of malignant melanoma with a fluorescent leak early in the arterial phase. The authors recommend fluorescein angiography as one of the diagnostic criteria in patients with pigmented iris tumors. Melanomas of the iris and ciliary body account for only a small proportion of the primary intraocular tumor and iris nevi, melanomas, cysts and pigmented cells must be considered when pigmented lesions are present in the iris or anterior chamber angle
