The introduction of optical coherence tomography angiography (OCTA) has remarkably expanded our knowledge of the ocular vascular alterations occurring in diabetes. In this article, a review of the prominent OCTA findings in diabetes is followed by a description of salient histological and anatomical features of microaneurysms, essential for the proper interpretation of in vivo imaging of these retinal vascular abnormalities. The recent employment of a three-dimensional (3D) visualization in OCTA imaging is also discussed. The latter imaging technique has granted a detailed characterization of microaneurysms in vivo.
光学相干断层扫描血管造影术（OCTA）的引入极大地扩展了我们对糖尿病患者眼部血管改变的认识。本文首先回顾了糖尿病中 OCTA 的主要发现，然后描述了微动脉瘤的显著组织学和解剖学特征，这对于正确解释这些视网膜血管异常的活体成像至关重要。还讨论了最近在 OCTA 成像中采用的三维（3D）可视化技术。后者的成像技术使我们能够对活体微动脉瘤进行详细的特征描述。
