Vision damage may begin long before type 2 diabetes is diagnosed
Amount of damage to corneal nerves rises in tandem with impaired glucose metabolism, Dutch researchers say

Nerve damage is a common side effect of type 2 diabetes and it might start in the eyes long before the condition is ever diagnosed, new research suggests.
In this study, scientists used neuropathy, or nerve damage, in the eye’s cornea as a proxy for the damage to nerves throughout the body.
