Abstract: 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)
