Project Description

Blinking is essential to spread the tear film over the surface of the eye and so keeps the eye moist and lubricated to ensure a smooth surface for refraction of light and provision of essential nutrients and protective antimicrobial molecules. With each blink the eyelids exert force on the corneal and conjunctival epithelial cells that line the ocular surface. It is widely recognised that cells actively respond to mechanical perturbation resulting in changes in intracellular signalling pathways for example. Contact lens wear and an altered tear film such as in dry eye may influence the normal response of the cells to the mechanical perturbation of blinking and so contribute to the discomfort often experienced by contact lens wearers and those with dry eye disease. Previously we developed an in vitro cell culture based mechanical model to begin studying the cellular effects of blinking (Qin G et al. 2018, Ocul Surf 16, 226-234).
The purpose of this project is to utilize the model to study the effects of blinking under conditions mimicking the adverse ocular environment of dry eye to determine if an enhanced pro-inflammatory response resulting from blinking exacerbates this common and sometimes debilitating ocular surface disease. The project involves utilizing mammalian cell culture, and cellular and molecular assays such as RT-PCR and enzyme immunoassays. Technologies such as CAD and3D printing as well as use of Matlab will also be used to develop and improve the mechanical model.
