Advantages and applications of AS-OCTA.

	Precise diagnosis	Efficacy evaluation
Conjunctiva	Identification of abnormal vasculature areas and conjunctival lesions	Longitudinal estimation of reperfusion
	Detection of deeper intrascleral vessels	Early evaluation of blood flow density on filtering bleb after trabeculectomy
	Assessment of limbal epithelial stem cell
Cornea and limbus	Detection of early corneal angiogenesis	Preoperative surgical planning by evaluating the depth and area of feeder vessel
	Detection of subtle abnormal vessels with corneal opacity	Repeatable evaluation of treatment effect by vascular progression and regression
	3D imaging of cornea layers	Better observation of corneal graft rejection
	Scan of predetermined depth of cornea
Ciliary body and iris	Early detection of small capillaries and microaneurysms flow	Evaluation of regressed neovascularization of the iris during anti-VEGF therapy
	Assessment of vascular anomalies in anterior uveitis	Exposure of persistent neovascularization
	Identification of iris lesions
