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.
