@drreeschecketts: For those affected by NAION, this feels like too little too late. For me, I interpret this as an additional need for caution and close monitoring on GLP-1 medications. They are not supplements. They are powerful tools with enormous potential benefit and real risk. Head over to my YouTube to find the full video that I had with ophthalmologist Dr. Marc Shomer. (Note — our conversation took place before the FDA label change but within a month of this announcement.) #GLP1 #NAION #FDA #MedicationSafety #ObesityMedicine
I read that the risk increases when the cup-to-disc ratio is 0.3 or lower. I assume this means the optic nerve ghas a more narrow opening thru the nerve bed, which can cause blood flow to decrease enough. And that means a ratio of say 0.7 allows more room for the optic nerve to go thru and thus less potential for BNAION. Wld that be correct?
