Re: How common is second NAION attack?

The idea is that low blood pressure contributes to attacks and drugs that lower your blood pressure act most when taken.? Your blood pressure drops anyway because of sleep and the drugs can add to that.? So taking them at night increases the risk.?

Could you expand on the morning avoidance of heart related drugs (i.e., blood pressure management) in the morning?
I've not heard of that before.

I have not, but over the years of this group there have been a few people who reported more events.? An NO said that is rare. less than 5%, because the attacks shrink the optic nerve and improve the disk ratio making another event very unlikely.? I am bilateral but I have not relaxed about protecting my vision.? I still do what I can to defend it like staying away as much as I can from anything the shrinks the blood vessels and taking any heart related drug in the morning.

I ?also have NAION in both eyes. After the first event, I was always told there was only a 15% chance of it recurring in the second eye. The second event has been tough, but I do still see well enough to drive in areas I¡¯m familiar with. The question that has recently come to mine and I plan to ask at my next appointment is - has anyone had this happen a third time, worsening the damage in either eye?

I recall reading in my early research that ?amongst all stricken once, chance of second eye being affected is 15% within 5 years. Can¡¯t recall the source.

Hi everyone?
?
By reading messages in this group, I have a feeling that second NAION is much more common than I expected.?
Is it a misperception? Or is it really quite common to have a second attack. I am very worried.

thanks
