Example of AS-OCTA scans in an eye with neovascular glaucoma. Abnormal iris neovascularization (a) are delineated by the AS-OCTA system (b), however, some vessels on the iris are not clearly seen on the AS-OCTA scans. This may be due to poor segmentation, image artefacts or thresholding issues. The corresponding area imaged with slit-lamp photography and OCTA are matched (bordered by red and yellow squares, respectively)
