The Sensitivity of the Cornea in Normal Eyes

Conference paper
Part of the Springer Series in Optical Sciences book series (SSOS, volume 8)

Abstract

The human cornea is probably endowed with the greatest density of nerve fibres of any tissue in the body. For this reason it is assumed to be the most sensitive structure (1) a characteristic which is, of course, essential to elicit the palpebral reflex which shuts the eyelids and therefore protects the eye. The cornea is innervated by the long and short ciliary nerves which are branches of the ophthalmic division of the fifth cranial nerve. These nerves lose their myelin sheath as they enter the cornea from the limbus so as not to interfere with the transparency. Only free nerve endings and supposedly some Krause end bulbs have been observed histologically (2). In this paper we shall review some of the factors which influence corneal sensitivity in normal (that is, not pathological) eyes. This information is essential as the basis from which to differentiate what is normal from what is pathological.
