Fundus photography of the left eye shows whitening and edema around the hypoperfused cilioretinal artery (a). The OCT B-scan image of the patient is shown at the level of the green dashed line in the foveal area (b). The hyperreflective band is seen on both the temporal and nasal sides of the fovea in the INL. The OCTA and en face OCT images in the SCP have been shown in c, d respectively. Vascular density in SCP appears normal and en face OCT shows hyperreflectivity around the involved cilioretinal artery. The OCTA in the DCP e shows decreased vascular density in the area around the ciliary artery (orange arrows). In addition to the upper half of the 6 × 6 OCTA image, the projection artifact is well seen in the lower part of the fovea (green arrows) (e). The en face OCT image from the DCP area well indicates the extent and border of the hypoperfusion area as a hyperreflective region (f). En face OCT image at the level of DCP demonstrated a confluent globular hyperreflective area (orange arrow) in the territory of the cilioretinal artery. A perivenular hyper-reflectivity with periarterial sparing was evident at the superior border of the main ischemic area (green arrows)
