Abstract:
As an exposed structure, the tear film is exposed to a variety of environmental conditions that may adversely affect its ability to fulfil its function. The aim of this work is to investigate tear film parameters and the interrelationship between these parameters during exposure to adverse environmental conditions. A wide range of parameters were monitored over a range of relative humidity (RH) and ambient temperatures. Evaporation rate and ocular surface temperature (OST) increased dramatically when room temperature increased from 5 to 25°C. Also changes in lipid layer thickness (LLT) and tear film stability were seen at ambient temperatures of less than 10°C. Changes in tear physiology were also seen during exposure to 5% RH compared to 40 RH%. All tear parameters observed (except OST) were adversely affected by the exposure to a desiccating environment. Some tear film parameters observed became typical of that seen in patients with dry eye.
