Exposure to a Controlled Adverse Environment Impairs the Ocular Surface of Subjects with Minimally Symptomatic Dry Eye

Abstract

Significant changes in comfort and the ocular surface tests were found after 2 hours of exposure to CAE. These results show the negative impact that an adverse environment, especially low RH, can have on the ocular surface. These alterations were fully reversible. This indicates that the CAE is a safe and functional condition in which to standardize DE diagnostic tests and evaluate therapeutics.
