case_images: Color fundus photography (CFP) and spectral-domain optical coherence tomography (SD-OCT) of the right eye (a, c) and the left eye (b, d) at presentation. CFP of the RE (a) shows mild venous engorgement and widespread peripheral retinal hemorrhages located in all 4 quadrants and multiple small areas of pale retina in the macula. CFP of the left eye LE (b) does not show any retinal abnormalities. SD-OCT scan of the macula of the RE (c) shows hyperreflective band-like lesions in the middle retinal layers of the macula (arrows) of the RE and no abnormalities at the macula of the LE (d).

SD-OCT of the RE showed no macular edema and hyperreflective band-like lesions in the middle retinal layers suggestive of paracentral acute middle maculopathy (PAMM). (Figure 1). OCT angiography (OCT-A) with a scanning area of 6*6 mm of the RE was indicative of attenuation of vascular flow signal in the superficial capillary plexus and patchy areas of vascular flow void in the deep capillary plexus (Figure 2). In fluorescein angiography (FA) of the RE, delayed venous filling was observed (Figure 3).

OCT-A shows mild attenuation of the vascular flow signal in the superficial capillary plexus (SCP) (c) and patchy areas of vascular flow void in the deep capillary plexus (DCP) (d) of the RE and normal flow in the SCP (e) and DCP (f) of the LE.
