Corneal Sensitivity in Tear Dysfunction and its Correlation With Clinical Parameters and Blink Rate.

ABSTRACT:

Purpose

To compare corneal sensitivity in tear dysfunction due to a variety of causes using contact and noncontact esthesiometers and to evaluate correlations between corneal sensitivity, blink rate, and clinical parameters.

Design

Comparative observational case series.

Methods

Ten normal and 33 subjects with tear dysfunction (meibomian gland disease [n = 11], aqueous tear deficiency [n = 10]-without (n = 7) and with (n = 3) Sjögren syndrome (SS)-and conjunctivochalasis [n = 12]) were evaluated. Corneal sensitivity was measured with Cochet-Bonnet and air jet esthesiometers and blink rate by electromyography. Eye irritation symptoms, tear meniscus height, tear break-up time (TBUT), and corneal and conjunctival dye staining were measured. Between-group means were compar
