%X 光学相干断层扫描(OCT)利用低相干光波来评估眼部特征。OCT是一种无创成像方式，可以快速生成眼部组织图像。两种常用的OCT包括谱域(SD)和扫描源(SS)。每一种都有不同的波长和组织穿透能力。OCT血管造影(OCTA)是OCT的功能延伸，它通过大量像素来捕获组织和潜在的血流。这使得OCTA可以在广泛的条件下测量缺血和血管的划分。本文综述了四种常见的视网膜疾病，包括糖尿病性视网膜病变(DR)、年龄相关性黄斑变性(AMD)、视网膜静脉阻塞(RVO)，视网膜动脉阻塞(RAO)。成像技术包括OCT和OCTA，除了在临床环境中进行常规诊断和管理外，还有助于了解疾病的发病机制和疾病进展的自然史。<br />
Optical coherence tomography (OCT) utilizes low coherence light waves to assess characteristics in the eye. OCT is a noninvasive imaging modality that generates images of ocular tissues at a rapid speed. Two commonly used iterations of OCT include spectral-domain (SD) and swept-source (SS). Each comes with different wavelengths and tissue penetration capacities. OCT angiography (OCTA) is a functional extension of the OCT. It generates a large number of pixels to capture the tissue and underlying blood flow. This allows OCTA to measure ischemia and demarcation of the vasculature in a wide range of conditions. This review focused on the study of four commonly encountered diseases involving the retina including diabetic retinopathy (DR), age-related macular degeneration (AMD), retinal venous obstruction (RVO), retinal arterial obstruction (RAO). Imaging techniques including OCT, and OCTA assist with understanding the disease pathogenesis and natural history of disease progression, in addition to routine diagnosis and management in the clinical setting.
