Corneal dystrophy, Fuchs endothelial, 4

Fuchs endothelial corneal dystrophy (FECD) is the most common genetic disorder of the corneal endothelium. Late-onset FECD is marked by thickening of Descemets membrane and excrescences, called guttae, that typically appear in the fourth or fifth decade. Disease progression results in decreased visual acuity as a result of increasing corneal edema, and end-stage disease is marked by painful epithelial bullae (summary by Riazuddin et al., 2013). For a discussion of genetic heterogeneity of Fuchs endothelial corneal dystrophy, see FECD1 (136800). [from OMIM]
