光学相干断层扫描血管成像在常见眼底病诊断中的应用进展

Advances in the application of optical coherence tomography angiography in the diagnosis of common fundus diseases

光学相干断层扫描血管成像(OCTA)是近年来应用广泛的非侵入性眼底血管成像技术,与传统光学相干断层扫描相比,其分辨率更高,扫描速度更快。与眼底荧光素钠血管造影和吲哚菁绿血管造影相比,OCTA无需注射造影剂,检查时间短,可清晰显示视网膜和脉络膜的三维结构,在多种眼底内科疾病的诊疗中均显示了其优越性。虽然目前临床上OCTA不能替代眼底荧光血管造影,但在一定程度上仍是眼底疾病诊断中一项不可或缺的辅助检查方法,本文对近年来OCTA在老年性黄斑变性、视网膜静脉阻塞、糖尿病视网膜病变和中心性浆液性脉络膜视网膜病变等常见眼底内科病诊断中的应用进展进行综述。

Optical coherence tomography angiography(OCTA)is a new noninvasive fundus angiography technique that has been widely used in recent years,and compared with traditional optical coherence tomography,OCTA has a higher resolution and a faster scanning speed.Compared with fundus fluorescein angiography and indocyanine green angiography,OCTA has its own advantages in the diagnosis and treatment of various fundus diseases,such as no need for the injection of contrast agent,a short time for examination,and clear display of the three-dimensional structure of retina and choroid.Although OCTA cannot replace fundus fluorescein angiography in clinical practice at present,it can still be used as an important auxiliary examination in the diagnosis of fundus diseases.Fer this reason,our article reviews the advances in the application of OCTA in the diagnosis of common fundus diseases such as senile macular degeneration,retinal vein occlusion,diabetic retinopathy,and central serous chorioretinopathy.
