Le film lacrymal chez le cheval : rôle et anomalies

Although the lacrimal film of the horse contributes greatly to the health and normal functioning of the cornea, it remains poorly understood. The origin of its components, its structure and its functions, as well as the diagnostic procedures aimed at detecting and confirming the conditions that can affect the lacrimal film are presented in this article. Quantitative and qualitative disorders are exposed, including the clinical signs and treatment. In particular, the proteolytic activity in the tear film in cases of corneal ulceration, which remain a common eye disease in horses, is described.
