Corneal neovascularization from a case of Fascicular Keratitis. Anterior Segment OCT Angiography (AS-OCTA) was used for the imaging. Dense vessel distribution is visualized in peripheral conjunctiva. Neovascularization originated from lower-right corner then grew towards the corneal center. A quantification tool was used indicates the area of new vessel for follow up of treatment. Cross-sectional B-scan at green line position, overlapped with flow signal in red color, suggested the NV located in inner side of cornea, which is important information for therapy decision.
