“Tear-deficient dry eye (keratoconjunc-
tivities sicca), and evaporative dry eye,
with some overlap between these two
categories, are two major categories of
dry eye recognized in the horse. Careful
examination of the eyelid margins, the
inner and outer surfaces of the upper
and lower eyelids, assessment of blink
and third eyelid movement, specific
testing of tear production, assessment
of corneal sensitivity, and slit-lamp
examination of the ocular surface before and after fluorescein dye application is recommended to detect dry eye problems. Rose Bengal dye application is also recommended in many cases. Facial nerve paresis is a possible complicating factor in some instances. Evaporative dry eye deserves closer scrutiny for it may be a contrib- utory factor when ocular surface disease such as keratomycosis is present. Factors which influence ocular surface health need more close examination in horses.”
