Abstract
Aim: a review of miRNA expression connected to epithelial mesenchymal transition studies in Fuchs’ endothelial corneal dystrophy (FECD). Methods: literature search strategy—PubMed central database, using “miRNA” or “microRNA” and “epithelial mesenchymal transition” or “EMT” and “Fuchs’ endothelial corneal dystrophy” or “FECD” as keywords. Experimental or clinical studies on humans published in English regarding miRNA profiles of epithelial mesenchymal transition in Fuchs’ endothelial corneal dystrophy published between 2009 and 2022 were included. Conclusion: The publications regarding the miRNA profiles of epithelial mesenchymal transition in Fuchs’ endothelial corneal dystrophy are scarce but provide some valuable information about the potential biomarkers differentiating aging changes from early disease stages characterized by epithelial mesenchymal transition. In the corneal tissue of FECD patients, miRNA-184 seed-region mutation as well as unidirectional downregulation of total miRNA expression led by the miRNA-29 were demonstrated. For early diagnostics the miRNA of epithelial mesenchymal transition in aqueous humor should be analyzed and used as biomarkers.
