The clinical landmarks of corneal dystrophies

The International Committee for Classification of Corneal Dystrophies, briefly IC3D, was founded to develop a new, internationally accepted classification of corneal dystrophies (CDs) based on modern clinical, histological and genetical knowledge. Being members of the IC3D, the authors of this chapter present a clinical landmark survey of the different CDs. The ophthalmologist is the first to examine and to diagnose a new patient with a probable CD using a slit lamp. The presented landmarks are supposed to be a bridge for the ophthalmologists to precisely define the corneal opacities of a presumed CD. This bridge makes it easier for them to study the IC3D publication and to get more information including adequate differential diagnosis.
