Diabetics are already more prone NAION. This studies contribution was to show that diabetics on GLP-1's are MORE prone. It does not show that the general population is more prone when taking GLP-1's.
I didn't check to see if other studies prove that.
- thrtythreeforty 2mo agoIt is well known that forcing a sudden drop in chronically high average blood glucose (like, from 200+ to a normal ish range) with insulin can cause vision loss. I wonder if it's the same mechanism?
- adam_arthur 2mo agoIt tends to happen when: 1) You must have a crowded optical disc as a precursor (low cup to disc ratio). Genetic and can be tested 2) You have stiff veins/arteries due to poor metabolic/cardio health 3) when blood pressure drops too much, blood flow can get cut off to the optical nerve temporarily due to reliance on high blood pressure due to 2 4) Due to loss of blood flow, optic nerve swells and closes blood flow into the eye due to 1
- adam_arthur 2mo agoIt's also true that having a crowded optical disc is pretty much a required precursor condition to suffering NAION. Which you can get checked for via a $50 optical scan. No crowded disc, very little risk. (Cup to Disc ratio of 0.2ish or less starts to present risk)
