A 54-year old female patient was referred to our clinic due to long-standing progressive right eye blurred vision. No relevant personal or familial history. Right eye best-corrected visual acuity was 6/10. On biomicroscopy examination, central subepithelial spiraled opacities were characteristic of Map-dot-fingerprint Dystrophy, also known as Epithelial Basement Membrane Dystrophy or Cogan's Microcystic Epithelial Dystrophy. The disease may result in decreased vision (as in this patient) and/or recurrent corneal erosions.
Pellucid marginal degeneration is a slowly progressive corneal ectatic condition often leading to severe visual impairment of working age people.
The peripheral corneal thinning location requires a large graft size, eventually a peripheral lamellar crescentic keratoplasty followed by a central penetrating keratoplasty.
Besides surgically more challenging, corneal transplantation is associated to increased risk of vascularization and rejection.

Named after the slit lamp appearance of corneal findings, Map-dot-fingerprint Dystrophy is the most common corneal dystrophy. Map-dot-fingerprint dystrophy, Cogan’s dystrophy, Cogan microcystic epithelial dystrophy, epithelial basement membrane dystrophy, and anterior basement membrane dystrophy all designate the same condition.
