title: Corneal sensitivity and topogometry in keratoconus.
abstract: Paracentral corneal topography was determined (with a topogometer) and corneal sensitivity was measured in 90 keratoconic eyes. Sensitivity was evaluated in a control group and found to be greater in all five sectors than the sensitivity found in keratoconus patients. The zone of marked corneal steepening was located infero-temporally in 59% of our patients, although steepening was found in other zones as well. Overall, sensitivity was greatest in the temporal cornea and lowest in the inferior cornea, this hypoesthesia coinciding with the area of pronounced corneal protrusion. Corneal sensitivity, which was diminished in contact lens wearers, recovered within 7 days after discontinuing contact lens wear.
