Chronic inflammation or aging can narrow the duct, slowing drainage without fully blocking it.

Tears in cats are produced by several glands, which collectively contribute to the aqueous and lipid layers of the tear film. cat tear duct

While technically a failure of the secretory glands, KCS affects the dynamics of the duct system. Without adequate tear flow, the nasolacrimal duct can become obstructed by desiccated mucus. In cats, KCS is less common than in dogs but is frequently associated with chronic FHV-1 infection, which can destroy lacrimal gland tissue. Chronic inflammation or aging can narrow the duct,

Dacryocystitis is a specific infection of the drainage apparatus. It is often secondary to a foreign body (such as a grass awn or seed) entering the punctum, or bacterial infection ascending from the nose. Without adequate tear flow, the nasolacrimal duct can
