“Tear-deficient dry eye (keratoconjunc-tivities sicca), and evaporative dry eye,with some overlap between these twocategories, are two major categories ofdry eye recognized in the horse. Carefulexamination of the eyelid margins, theinner and outer surfaces of the upperand lower eyelids, assessment of blinkand third eyelid movement, specifictesting of tear production, assessmentof corneal sensitivity, and slit-lampexamination 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.” — Tear-deficient and evaporative dry eye syndromes of the horse by Sheila M. Crispin
