What is the suggested follow-up interval after NAION?

• A. 1-2 months
• B. 1 week
• C. 6 months
• D. 1 year

Answer: (A)

The timing of follow-up after NAION centers on watching how the optic nerve and vision change in the first weeks to months, and on catching any involvement in the fellow eye early. After an acute NAION event, disc edema and visual function can evolve over weeks, and the risk of another event in the other eye is highest in the early period. Checking patients every 1–2 months provides a practical balance: you can confirm that the edema is resolving, document stabilization or any new visual changes, and reinforce management of vascular risk factors without subjecting the patient to overly frequent visits. More frequent follow-up (like within a week) isn’t usually necessary once the acute period is past, and waiting 6 months to a year risks missing early progression or changes in vision.
