Abstract
The effect of corneal edema and the effect of penetrating keratoplasty upon the accuracy of electronic applanation tonometry were studied in rabbits. Pressure readings made directly from cannulas in the anterior chamber correlated well with those made by electronic applanation tonometry both in severe corneal edema and 24 hours after penetrating keratoplasty. The advantages of electronic applanation tonometry in patients with corneal disease are discussed.
