We in ophthalmology are fortunate to be able to measure
quantitatively many aspects of ocular morphology and visual
function. These measurements are either objective (e. g.
electroretinography, tonometry, electromyography, visually evoked
responses, etc.) or subjective and psychophysical (e. g. visual
acuity, visual fields, color vision, etc.). One aspect of corneal
physiology and pathology which has so far escaped careful and
reliable measurements is corneal sensitivity. Previous attempts
have been rather crude and can be compared to measuring intraocular
pressure by digital compression. Professor Draeger has for the last
decade and a half directed his attention to the question of
esthesiometry of the cornea. He has a gift for constructing and
devising new ingenious ocular instruments. His handheld tonometer
is a splendid example. He has now applied the principle of this
instrument to the new electronic optical esthesiometer. In many
publications he has reported on his first results using this modern
technique to study corneal physiology and evaluate certain
pathologic conditions. In this monograph Professor Draeger has
collected all of his material and reports on his long experience.
The usefulness of this instrument is just beginning to be
appreciated. It is obvious that this new measuring device will help
us in the fitting of contact lenses, evaluating herpes simplex
infections of the cornea, follow the postoperative course of
patients with a penetrating keratoplasty, etc.
