Qualitative and quantitative abnormalities in primary components of the tear can alter the dynamics of the lacrimal film, compromising its function. Lipids, an aqueous fraction and mucoproteins constitute the lacrimal film. Keratoconjunctivitis sicca (KCS) is a disease commonly diagnosed in dogs. It is characterized by the deficiency of the aqueous fraction in the lacrimal film that results in dryness, inflammation of the conjunctive and cornea with progressive corneal illness and reduction of vision and pain. Due to the significant contribution of the third eyelid lacrimal gland to the production of the aqueous fraction of the lacrimal film, the removal of this gland when prolapsed is an important cause of iatrogenic keratoconjuctivitis sicca. This paper describes a clinical case of iatrogenic keratoconjuctivitis sicca in a 10 month-old Boston Terrier which was caused by the removal of the third eyelid lacrimal gland due to its prolapse.
