The dependence of acid-base balance in the aqueous humor on carbon dioxide and oxygen diffusion through the cornea (author's transl)

Abstract

In 20 rabbits the effect of, gas exchange, between the aqueous humor and surrounding air through the cornea, on the acid-base balance in the aqueous was investigated. It was found that tight eye closure leads to a decrease of oxygen partial pressure in the aqueous humor. A concurrent displacement of the acid-base balance in the form of a mixed acidosis (respiratory and metabolic acidosis) was demonstrated.
