Dry eye syndrome is one of the most common ophthalmology diseases. With the improvement of non-invasive tear extraction methods, tear protein analysis becomes a best choice for the diagnosis and evaluation of efficacy of dry eye. Methods that have been used for tear proteomics research include protein chip technology and mass spectrometry. The relationship between the protein in the tear fluid and its concentration and different pathological conditions has important value in the research of dry eye syndromes. This article reviews the latest developments in the field, the application of tear proteomics research and current practical issues,it will provide highlights for the understanding of molecular mechanism of dry eye syndromes and benefits for potential molecular diagnosis of dry eye syndromes in the future.
