To identify features of posterior polymorphous dystrophy (PPMD) by in vivo
confocal microscopy, the corneas of a female patient with PPMD were examine
d using slit-lamp biomicroscopy and slit-scanning in vivo confocal microsco
py. Characteristic endothelial vesicular and band lesions were seen clinica
lly and easily identified using in vivo confocal microscopy. However, endot
helial pleomorphism, an increased density and reflectance of posterior stro
mal keratocytes, and prominence of corneal nerves were also delineated. In
vivo confocal microscopy enhances clinicopathological diagnosis and follow
up of corneal dystrophies with subtle clinical presentations, such as PPMD.
