Changes of Peripapillary Capillary Density in Patients with Vogt–Koyanagi–Harada Disease Evaluated by Optical Coherence Tomography Angiography

Figure 1

Representative fundus photographs and OCTA images of the right eye of a 50-year-old female with acute VKH who presented with significant optic disc swelling. Images were taken before (a–d) and after (e–h) treatment for 6 months. (a) Fundus photograph before treatment revealing radial folds between the macular and optic disc and evidence of macular swelling. (e) Fundus photograph taken after treatment revealing a gray optic disc with a clear boundary and a slightly thinner artery. (b, f) The RPC vessel perfusion density decreased after treatment in all four quadrants. (c, g) The retinal plexus vessel perfusion density decreased after treatment in the infranasal, supratemporal, and infratemporal quadrants, but increased in the supranasal quadrant. (d, h) The choriocapillaris vessel perfusion density increased after treatment in all four quadrants.
