Tear fluid contains organic and inorganic constituents, variations in their relative concentrations could provide valuable information and can be useful for the detection of several ophthalmological diseases. This report describes the application of the lab-assembled light-emitting diode (LED)-based high-performance liquid chromatography system for protein profiling of tear fluids to diagnose dry eye disease. Principal Component Analysis (PCA), match/no-match, and Artificial Neural Network (ANN) based binary classification of protein profile data were performed for disease diagnosis. Results from the match/no-match test of the protein profile data showed 94.4% sensitivity and 87.8% specificity. ANN with the leaving one out procedure has given 91.6% sensitivity and 93.9% specificity.
泪液含有有机和无机成分，它们相对浓度的变化可以提供有价值的信息，并且有助于检测多种眼科疾病。本报告描述了实验室组装的基于发光二极管（LED）的高效液相色谱系统在泪液蛋白质谱分析以诊断干眼病中的应用。为了疾病诊断，对蛋白质谱数据进行了主成分分析（PCA）、匹配/不匹配以及基于人工神经网络（ANN）的二元分类。蛋白质谱数据的匹配/不匹配测试结果显示敏感性为94.4%，特异性为87.8%。采用留一法的人工神经网络给出的敏感性为91.6%，特异性为93.9%。
