摘要

黄斑毛细血管扩张2型(MacTel)是一种双侧视网膜疾病,似乎仅限于黄斑中央凹附近区域。我们在此报告一个不寻常的MacTel表现,在黄斑处有大量色素沉积。右眼眼底黄斑及直角小静脉可见大量色素沉积。左眼眼底因视网膜下纤维化、深色色素团块及黄斑内呈直角小静脉而呈灰白色。病变在多色成像和蓝色反射成像上突出显示。双眼光谱域光学相干断层扫描(SD-OCT)显示视网膜内侧高反射率,对应色素聚集区域。

An unusual presentation of macular telangiectasia type 2 with a large pigment deposit.
Macular telangiectasia type 2 (MacTel) is a bilateral retinal disease that seems to be limited to the juxtafoveal region of the macula. We herein report an unusual presentation of MacTel with a large pigment deposit at the macula. Fundus of the right eye showed a large pigment deposit at the macula and right-angled venule. The left eye fundus showed a grayish discoloration due to subretinal fibrosis, dark pigment clumps and right-angled venule in the macula. Lesions were highlighted on multicolor imaging and blue reflectance imaging. Spectral domain optical coherence tomography (SD-OCT) of both eyes showed hyperreflectivity on the inner aspect of the retina corresponding to the area of pigment clumping.
