Abstract
Ultramarathon-associated corneal edema is a rare phenomenon. We report a case of a patient who presented with bilateral corneal edema following an ultramarathon. The corneal edema resolved without sequelae 48 h later. The authors hypothesize that the additive effect of enhanced glycolysis, an increased lactate level in the aqueous humor, and oxidative stress alters the normal endothelial regulation of the cornea and leads to corneal edema.
