Esthesiometer
esthesiometer[es‚thē·zē′äm·əd·ər] (engineering) An instrument used to measure tactile sensibility by determining the distance by which two points pressed against the skin must be separated in order that they be felt as separate. Also spelled aesthesiometer. Esthesiometer an instrument for determining tactile sensibility. The esthesiometer permits investigation of stimulus thresholds for pressure, touch, vibration, heat, and cold. The instrument applies increasing or decreasing amounts of irritation to a specific area of the skin, a mucous membrane, or a cornea and alters the action time of an irritant or the distance between two irritants. Modern esthesiometers also regulate the rate of variation in the intensity of an irritant. esthesiometer

Synonym(s): tactometer, aesthesiometer. [esthesio- + G. metron, measure]aesthesiometer Instrument for the measurement of sensitivity, especially tactile. The cornea and eyelid margins are the ocular structures measured. There are many types of aesthesiometers. The most common is that of Cochet-Bonnet (Fig. A7). It consists of a nylon monofilament of constant diameter which, depending upon its length, can exert more or less pressure. The length at which the subject responds to represents the corneal touch threshold. Others are non-contact and use a pulse of pressurised air or gas to stimulate the cornea. Note: also spelt esthesiometer. See corneal fragility; corneal hyperaesthesia; corneal sensitivity; corneal touch threshold. " > Fig. A7 Cochet-Bonnet aesthesiometer |
