Application of optical coherence tomography angiography in ocular anterior segment diseases / 中华实验眼科杂志

ABSTRACT

Optical coherence tomography angiography (OCTA) is a rapid,noninvasive new blood flow imaging technique that was first applied to retinal retinopathy and acquired retinal vascular imaging in only a few seconds.Compared with the traditional optical coherence tomography (OCT),OCTA analyze has the advantages of higher resolution,faster scanning speed,quantitative blood flow,etc.OCTA not only can more accurately and qualitatively analyze ocular vascular morphology,but also can measure blood vessels and blood flow perfusion noninvasively and quantitatively.With the application of anti angiogenesis drugs in the anterior segment,it is important to evaluate the neovascularization of the cornea and iris in order to guide the clinical medication and evaluate the therapeutic effect.This article reviewed the application of OCTA in ocular anterior segment diseases,such as cornea and iris diseases,etc.
