Dec 21 2018 by Fawwaz F Al Mamoori, MD, Medical Retina Consultant
70-year-old female patient known to have hypertension, presented with acute deterioration of left eye vision, best corrected visual acuity was 6/60. Fundoscopic exam showed abnormal foveal reflex whiting .SS-OCT B scan showed also a hypereflectivity of the inner plexiform layer (IPL), inner nuclear layer (INL) and OPL layer(figure-2, A). FA images were also normal(figure-2 B). Segmented angiographic images elucidate ischemia and capillary drop out predominantly at the level of DCP but less severe than Case 1 (fig 2, C). Correspondingly, Enface highlights hyper reflective areas in a fern like distribution in the middle retina at similar depth of ischemic lesions demonstrated on B scans and OCTA (fig 2, D)
