[Correlation between bleb-like, fingerprint and map-like dystrophy of the cornea].

In epithelial basal membrane dystrophy of the cornea Bron's dystrophy plays a prominent role (frequently combined with fingerprint dystrophy). It can be visualized only in retroillumination, and is without doubt the most common corneal dystrophy. It should be distinguished from Cogan's microcysts, which were seen in only 11% of the authors patients. The incidence of map dystrophy is about the same, while subepithelial plaques are least frequently observed.
