Contact lens wear is a major cause of corneal infiltrative events (CIEs), which present with different forms and severity. The incidence of contact lens related CIEs ranges as high as 6.0 % in symptomatic cases and 44% in asymptomatic cases per year. The present study aims to identify tear metabolites expressed during CIEs that can be used as biomarkers of ocular inflammation, and to explore the biological pathways associated with CIEs. Three major prospective studies will be carried out by collecting tear samples from the patients with CIEs at School of Optometry and Vision Science (SOVS), UNSW and WSLHD Westmead Hospital, Westmead and unaffected controls using Ultra-High-Performance liquid chromatography (UHPLC MS/MS) 1) untargeted metabolomic profiling of tear samples to identify biomarkers associated with CIEs; 2) targeted metabolomic study to confirm biomarkers identification and mining of biological pathways; and 3) validation study of biomarker characterisation. The raw data will be converted to a matrix of chromatographic peaks and will generate a peak table of m/z, retention time and alignment of raw chromatographic data to identify metabolites biomarkers. This study will be the first study to develop methods for the tear sampling and analysis using UHPLC MS/MS for the study of CIEs.
This study is believed to improve understanding of CL-related and non-CL- related infiltrative events to identify the risk groups for both onset and the severity of the disease, the pathway associated with the metabolic interaction and guide early intervention and prevention in future.
