NAION or Non-Arteritic Ischemic Optic Neuropathy is a sudden vision loss caused by reduced blood flow to the optic nerve which may worsen over time.  It can be associated with vascular disease or even use of Viagra.  Managing risk factors like hypertension and cholesterol can reduce the chances of it happening to the other eye.  Our stem cell treatment is the first to show statistically significant improvement in NAION with 89.5% of damaged eyes improving or stabilizing. Research supports that the stem cells fuse and regrow lost neurons in the optic nerve.
