摘　　要：眼底影像学在视网膜和脉络膜疾病的诊断中发挥着关键作用。相干光层析血管成像术(OCTA)通过采集信号重建血管结构,能够清晰地展示视网膜血管情况,具备扫描速度快和无创性等显著优势。尽管由于检测原理限制,OCTA无法动态评估血管功能,但探讨OCTA未来应用的发展趋势及其是否能最终替代眼底血管造影术,仍是当前医学界关注的焦点。OCTA因其能够提供传统眼底血管造影术无法获取的多种参数,且随着OCTA检查结果眼底覆盖面积的扩大及伪影消除能力的提升,其在多种视网膜和脉络膜疾病的识别率已显著提高,OCTA在临床上的广泛应用已是大势所趋。尽管目前超广角OCTA在临床应用中还不能全面替代血管造影术,但随着临床实践的深入、临床研究的扩展以及技术的持续创新,OCTA在未来有望逐步替代眼底血管造影术。Fundus imaging plays a pivotal role in diagnosing retinal and choroidal diseases.Optical coherence tomography angiography(OCTA),by capturing signals to reconstruct vascular structures,offers a clear depiction of retinal vasculature with notable advantages such as rapid scanning and non-invasiveness.Although OCTA,due to its underlying principles,cannot dynamically assess vascular function,exploring its future applications and potential to eventually replace traditional fundus angiography remains a key focus in the medical community.OCTA provides multiple parameters that conventional fundus angiography cannot obtain.With the expanding coverage area of OCTA scans and improvements in artifact elimination,the detection rate of various retinal and choroidal diseases has significantly increased,making the widespread clinical application of OCTA an inevitable trend.Although ultra-widefield OCTA cannot yet fully replace angiography in clinical practice,with continued clinical practice,expanded clinical research,and ongoing technological innovation,OCTA is expected to gradually replace fundus angiography in the future.
