First, B scans of the macula will be obtained and anatomical alterations of retinal architecture will be noted. Next, OCT angiography scans in a 4.5x 4.5 mm circle centered on the fovea will be then obtained. Analysis and interpretation of the enface images of the superficial and deep retinal capillary plexus as well as choriocapillaries will be performed. Areas of capillary dropout, abnormalities of retinal capillaries and vessels such as looping, dilated segments, microaneurysms as well as FAZ area will be documented.
