Bietti's crystalline dystrophy (BCD) is a rare autosomal recessive retinal dystrophy characterized by deposition of crystals in the retina. The purpose of this article is to describe retinal abnormalities in BCD using multimodal imaging. An 18-year-old girl presented with decrease of vision and nyctalopia. She was assessed with color fundus picture, red-free photographs, short-wave autofluorescence, spectral-domain optical coherence tomography (OCT) and en face OCT and was diagnosed to have BCD based on typical presentation. Retinal crystals were better visualized on en face OCT as compared to conventional B scan OCT.
Bietti 的结晶性视网膜营养不良(BCD)是一种罕见的常染色体隐性视网膜营养不良,其特征是视网膜中晶体的沉积。本文的目的是使用多模态成像描述 BCD 的视网膜异常。一位 18 岁女孩因视力下降和夜盲就诊。她接受了彩色眼底照片、无赤光照片、短波自动荧光、谱域光学相干断层扫描(OCT)和共焦 OCT 检查,并根据典型表现诊断为 BCD。与传统的 B 扫描 OCT 相比,共焦 OCT 可以更好地观察到视网膜晶体。
