[Cornea in diabetus mellitus]

Abstract

Diabetus mellitus is associated with numerous ocular complications. Diabetic keratopathy occurs in response to a neuropathy of the ophthalmic division of the trigeminal nerve, but also as a result of epithelial subclinical abnormalities, limbal vasculopathy and decrease in tear production. It comprises several symptomatic corneal conditions inducing superficial punctate keratopathy and persistent corneal epithelial erosions; the latter can progress to corneal ulceration and is often resistant to routine clinical management.
