Color fundus photography of the left eye shows whitening and edema at the superior region of the macula (a). The foveal B-scan SD-OCT cut is shown below the fundus photography. The temporal side of fovea shows a hyperreflective band in the INL consistent with PAMM diagnosis. The OCT horizontal B-scan image of the patient at three different levels above the fovea shows the INL hyperreflective band (b). The OCTA image in the SCP and DCP besides the corresponding en face-OCT images at these levels have been shown in c, d. DCP image (4-D) shows a decrease in vascular density around the fovea. Also, the projection artifact is nicely seen in the upper and lower parts of the fovea. The en face OCT image at the level of DCP well designates the extent and border of the hypoperfusion area as a hyperreflective fern-like region and also depicted involvement of the fovea, explaining the reduced central vision in this patient
