INTRODUCTION
Melanocytoma of the optic disc is a benign lesion.
OBJECTIVE
To describe a case of optic disc melanocytoma
CASE
A 48-year old lady presented with gradual visual impairment associated with a floater. The right eye fundus examination showed a mass uniformly dark black in colour on the optic disc. The mass completely obscured the fluorescence on fluorescein angiography and was thus differentiated from malignant melanoma.
CONCLUSION
Optic disc melanocytoma can present with visual impairment and a floater. Fluorescein angiography can be useful to differentiate between malignant melanoma and melanocytoma.
引言
视盘黑色素细胞瘤是一种良性病变。
目的
描述一例视盘黑色素细胞瘤病例。
病例
一名48岁女性因逐渐出现视力障碍并伴有飞蚊症前来就诊。右眼眼底检查显示视盘上有一个颜色均匀为深黑色的肿物。该肿物在荧光素血管造影中完全遮挡了荧光，因此与恶性黑色素瘤相鉴别。
结论
视盘黑色素细胞瘤可表现为视力障碍和飞蚊症。荧光素血管造影有助于鉴别恶性黑色素瘤和黑色素细胞瘤。
