摘　　要：眼前节相干光断层扫描血管成像(anterior segment-OCTA,AS-OCTA)的研究尚处于起步阶段,目前可用于角膜、虹膜、巩膜和结膜等眼前节疾病的诊断和治疗评估,如客观量化角膜血管化,评估眼化学烧伤后角膜缘结膜缺血、兔诱导角膜新生血管模型;清晰可见虹膜各层血管分布,可检测出早期出现的亚临床期虹膜新生血管等。OCTA系统主要为眼后节成像而设计,应用于眼前节时有其局限性,需调整扫描协议和使用眼前节适配器透镜。(国际眼科纵览,2022,46:134-138)The research of anterior segment coherence tomography angiography(AS-OCTA)is still in its infancy.At present,it can be used in the diagnosis and treatment evaluation of anterior segment diseases such as cornea,iris,sclera and conjunctiva.It can objectively quantify corneal vascularization,evaluate limbal conjunctival ischemia after ophthalmic burn and evaluate inducing corneal neovascularization model in rabbits.The distribution of blood vessels in each layer of iris and the early subclinical iris neovascularization can be clearly detected with AS-OCTA.The OCTA system is mainly designed for posterior segment imaging,which has its limitations when applied to the anterior segment.It is necessary to adjust the scanning protocol and to use the anterior segment adapter lens for anterior segment application.(Int Rev Ophthalmol,2022,46:134-138)
