I participated in a covid vaccine trial early in the COVID days and have had 4 boosters since without any issues. ?I have flown on overseas trips, no problems, had surgery, no problems, had a cpap and then inspire when my AHI was within reason. ?At the time of NAION I was and had been taking daily 325mg ASA for decades to the point I bruised and bled easily. My blood pressure tends to run higher and my cholesterol levels are very low. As far as I can tell, most of the ¡°possible¡± factors causing NAION are not well defined and are at this point questionable.?
