OCTA of Drusen in Non-Neovascular AMD Cases. (A) 3 x 3 mm en-face images of the right eye of a 74 year old Caucasian man with non-neovascular age-related macular degeneration (AMD) using the Angiovue optical coherence tomography angiography (OCTA) software of the RTVue XR Avanti (Optovue, Inc., Fremont, CA). (A1) En-face structural OCT demonstrating areas of choriocapillaris alteration. (A2-4) OCT angiograms of the choriocapillaris and corresponding x-axis OCT b-scans at the cross-sections shown by the green line of the OCT angiograms. The three soft drusen shown are associated with areas of decreased signal in the choriocapillaris, which could indicate flow impairment. (B) 3 x 3 mm en-face images of the left eye of an 80 year old Asian woman with non-neovascular AMD using the Angiovue OCTA software of the RTVue XR Avanti (Optovue, Inc., Fremont, CA). (B1) En-face structural OCT demonstrating areas of choriocapillaris changes. (B2-4) OCT angiograms of the choriocapillaris and corresponding x-axis OCT b-scans at the cross-sections shown by the green line of the OCT angiograms. The druse in B2 is not associated with choriocapillaris loss. The other two soft drusen shown correspond to areas of decreased signal in the choriocapillaris, which could indicate flow impairment.
