Abstract
A summary of the fine structure of presumably normal cornea is presented and is augmented by details not previously published. Certain differences noted between epithelial and endothelial cells are discussed, in view of their possible bearing on the function of these layers. Corneal tissue obtained from patients afflicted with keratoconus, cornea guttata, or Wilsons disease is compared with normal cornea, and a scarred rabbit cornea is compared with its normal counterpart. The widespread alterations in fine structure are described and discussed.
