confoscan features in a case of meesmann corneal dystrophy

purpose: to report the confocal scan features in a case with clinical diagnosis of meesmann corneal dystrophy (mcd). case report: a 17-year-old female with recurrent episodes of corneal erosion and a clinical diagnosis of mcd underwent in vivo confocal scanning of both corneas. the confocal scan features included hyporeflective round-shaped areas measuring 6.8 to 41.4 mm within the superficial epithelium, diffuse hyperreflective spots in the basal epithelium and high contrast  but ill-defined irregular areas at the sub-basal epithelial region. except for the subepithelial nervus plexus which was not apparent because of the subepithelial hyperreflectivity, other corneal layers looked unremarkable. conclusion: confocal scan is a non-invasive in vivo imaging method which should be considered as a valuable diagnostic adjunct in delineating the microstructural features of meesmann corneal dystrophy.
