Three Cases of Arteritic Anterior Optic Neuropathy Several Months after COVID-19 Vaccination

Figure 2

Colour photography, optical coherence tomography, and temporal artery biopsy of case 2. (a) The tilted disc in the high myopic right eye seems to be difficult in evaluation with or without swelling. Dense nuclear cataracts obscure disc swelling in the left eye. (b) Vertical scan optical coherence tomography image in the right eye (above) is unclear due to poor fixation and tilted disc. Vertical scan in the left eye (below) shows optic nerve swelling (blue arrowheads). (c) Haematoxylin and eosin stain (left) shows neutrophil/lymphocyte infiltration in the tunica media (red circle). Elastica van Gieson stain (right) shows thickening of the outer membrane (blue arrow) and separation/torn of the inner elastic plate (white arrow).
