Association Between Limbal Function and Tear Proteomics in Chronic Ocular Diseases: Focusing on Glaucoma

Background Intact corneal epithelium is important for the defense on the ocular surface, and the function of limbal stem cells is crucial to maintain its integrity. Certain chronic eye diseases, such as glaucoma, require long-term medication use. However, glaucoma patients often exhibit corneal punctate erosions and ocular surface inflammation. In cases where medication has been used for an extended period, patients may even show symptoms similar to limbal stem cell deficiency. Understanding how glaucoma medications affect the function of corneal limbal stem cells is a critical clinical issue. Objectives To evaluate the effect of glaucoma and anti-glaucoma agents on corneal epithelial and limbal epithelial thickness as a surrogate of limbal stem cell function, and to understand the association between tear fluid proteome and limbal function in glaucoma patients. Methods We planned to include 90 subjects with glaucoma, and analyze the absolute thickness and variation of corneal epithelium and limbal epithelium. Tear fluid samples will be collected and proteomic analysis will be performed to elucidate the association between protein. Anticipated Results To elucidate the impact of different types and cumulative doses of glaucoma medications on the thickness of the corneal epithelium and limbal epithelium, and to understand the relationship between limbal function and tear proteomics in glaucoma patients. The expected results may help develop early detection methods for change…
