Optical coherence tomography angiography of the iris in an active anterior uveitis patient highlights progressive decrease of the vessels caliper and dilation with control of inflammation. A 36-year-old patient with acute anterior uveitis examined with optical coherence tomography angiography of the iris at baseline (top row, 4+ cells), after 7 days of prednisolone acetate 1% every 2 h (middle row, 2+ cells) and at 15 days (bottom row, quiet). The progressive in the caliper of the vessels is qualitatively visible in the greyscale rendering (middle column) and in the 3D extrusion of the reflectivity (right column), and is confirmed by the histogram (bottom) that compares point-by-point pixels reflectance of the iris vessels when inflamed (blue line), when less inflamed (orange) and quiet (flat grey line). This anterior uveitis patient is the perfect example of how optical coherence tomography angiography of the iris can detect inflammation through dilation of the iris vessels
