"On examination, there is ipsilateral optic disc swelling which later progresses to atrophy and pallor 4. In cases of sequential NAION, pseudo-Foster Kennedy syndrome may be present 4. A small cup-to-disc ratio is usually observed in the unaffected eye."
"DWI: may have diffusion restriction of the optic disc"
"T1 C+ (Gd): may have enhancement of the optic disc"
"Non-arteritic anterior ischaemic optic neuropathy (NAION or NAAION) is a form of ischaemic optic neuropathy."

"Significant recovery of visual acuity occurs in approximately 40% of patients 4. The risk of the fellow (unaffected) eye subsequently developing NAION is approximately 15% over 5 years 9."
"No disease-modifying treatment exists 4. There is weak evidence to suggest that aspirin may have a role in secondary prevention 11."
