Ophthalmoscopic examination showed a swelling of the optic nerve (Fig. 1a, black arrow) as well as cotton wool spots (Fig. 1a, white arrow). Optical coherence tomography (OCT) angiography showed hypoperfusion within the superficial and deep retinal capillary plexus in the affected area (Fig. 1b, red arrow).
a Ten weeks later, a fundus photograph of the left eye shows a normal optic disc margin. b The optical coherence tomography scan demonstrates thinning of the outer retinal layer in the papillomacular bundle (white arrow).

Ten weeks later, the patient's visual acuity had increased to 20/20, and the swelling of the optic disc had subsided (Fig. 2a). Although OCT showed thinning of the outer retinal layer in the papillomacular bundle (Fig. 2b, white arrow) and vitreous opacification, no retinal pigment epithelial changes were seen.
