(A) Mactel2 in a 58-year-old with right-angle veins and cavitations imaged with volume rendered OCTA with segmentation of the retinal cavitations from the structural OCT data. The foveal avascular zone is smaller and displaced toward the central focus of the vascular lesion in the temporal macula. Note the vessels of the perifoveal ring are drawn toward the center of the vascular aggregate and for angular figures and their apices (one of which is shown by the open arrow) point toward the center of the vascular aggregate (Modified from Spaide et al. Retina, 2017). (B) A vector field map showing the retinal displacement over a 10 year period. The tissue displacement reveals an epicenter in the temporal juxtafoveal macula. (C) A color-coded volume rendering with the superficial vessels shown in blue, the deep plexus red, the vessels deeper than the deep plexus (as occurs in MacTel2), yellow and vessels below the level of the RPE, green. (D) When viewed from the choroid, the proliferating vessels under the RPE have an enlarged saccular nature, which is different from the vessels in the overlying layers.
