Corneal sensation was determined by a Cochet-Bonnet filament esthesiometer (Luneau Ophtalmologie, France) [21].
The patient did not experience any eye pain and corneal sensitivity measured with Cochet-Bonnet esthesiometer was <10 mm in the right eye and 60 mm in the left, showing remarkable decline of corneal sensitivity in the right.
Corneal esthesiometry was carried out as previous description using a Cochet-Bonnet esthesiometer (Luneau Ophtalmologie, Chartres Cedex, France).[10],[11] The nylon monofilament had a maximal extended length of 60 mm with a diameter of 0.12 mm.
The Cochet-Bonnet esthesiometer is used to determine the corneal touch threshold (CTT), at which a blink reflex, retraction of the eyeball or incursion of the third eyelid is induced in response to a stimulus (MULLER et al., 2003; KAPS et al., 2003; WIESER et al., 2013).
Corneal sensitivity was measured using the contact nylon thread Luneau 12/100 mm Cochet-Bonnet esthesiometer (Luneau; Prunay-Le-Gillon, France).
