On examination, (LE) fundus revealed focal constriction of arteries and veins, soft exudates, dot-blot and flame-shaped hemorrhages in branch vein distribution, attempt at macular fan formation, and area of macular edema [Figure 1]. (LE) optical coherence tomography (OCT) revealed neurosensory detachment with cystoid macular edema [Figure 2].
Optical-coherence-tomography. (a) Left eye First-visit: neurosensory detachment. (b) Two months: Cystoid macular edema, subfoveal hyperreflectivity, and disruption of the external limiting membrane, the ellipsoid zone, and interdigitation zone in the foveal region. Features suggestive of acute macular neuroretinopathy

On examination, (LE) fundus revealed focal constriction of arteries and veins, soft exudates, dot-blot and flame-shaped hemorrhages in branch vein distribution, attempt at macular fan formation, and area of macular edema [Figure 1]. (LE) optical coherence tomography (OCT) revealed neurosensory detachment with cystoid macular edema [Figure 2]. Distortion of SCP-DCP on OCTA persisted, which was the only persistent defect explaining the visual complaint of the patient [Figure 2].
Fluorescein angiography. (a) Right eye and (b) left eye shows normal foveal-avascular-zone, few areas of the delayed filling (inferotemporal-vascular-arcade) with capillary leakage

Disc leakage was also noted [Figure 3].

There was the subfoveal area of hyperreflectivity and retinal thinning [Figure 4]. (RE)
Optical coherence tomography-angiography (final-visit). (a) right eye: Normal. (b) left eye: Distortion of superficial and deep capillary plexus with preservation of retinal pigment epithelium and choroid

OCTA was normal. OCTA (LE) showed distortion of retinal superficial and deep capillary plexus (SCP-DCP) inferotemporal to foveal center [Figure 5].
