How can anterior ischemic optic neuropathy be prevented?

Controlling the risk factors associated with NA-AION is an important preventive measure.

In addition, people who have risk factors should avoid the use of blood pressure-lowering medications or erectile dysfunction drugs before bedtime. The combination of such drugs along with the normal drop in blood pressure while sleeping could be enough to interrupt blood supply to the optic nerve.

For A-AION, continued use of corticosteroids is recommended to avoid further loss of vision. Close follow-up with a rheumatologist is needed.
