Abstract

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.

摘要

2型黄斑毛细血管扩张症(MacTel)是一种双侧性视网膜疾病,似乎局限于黄斑的近黄斑中心凹区域。我们在此报告一例MacTel的不寻常表现,其黄斑处有一大块色素沉着。右眼眼底显示黄斑处有一大块色素沉着和直角小静脉。左眼眼底显示由于视网膜下纤维化、深色色素团块以及黄斑处的直角小静脉而呈现灰白色变色。病变在多色成像和蓝色反射成像中更为明显。双眼的光谱域光学相干断层扫描(SD-OCT)显示,视网膜内侧对应色素团块区域有高反射性。
