IC3D classification of corneal dystrophies

The International Committee for Classification of Corneal Dystrophies (IC3D) has provided an update of our knowledge on corneal dystrophies. This chapter gives the summary of clinical findings, onset, course, genetics, nosology, light and electron microscopy as well as immunohistochemistry for 25 different entities included as corneal dystrophies in this survey. A category number from 1 through 4 is assigned, reflecting the level of evidence supporting the existence of a given dystrophy.
