Image A shows a small crowded optic disk, also known as “disk at risk”, which is a structural risk factor for NAION. Image B shows the appearance of the optic nerve head in NAION with pallor, edema, and flame hemorrhaging[2].

Image C exhibits a normal cup to disk ratio, making NAION less likely than AAION, which is represented in Image D[2].
