Keratoconjunctivitis Sicca

(Also known as “Dry Eye Syndrome”)

What is Keratoconjunctivitis Sicca (KCS)?

KCS is an eye condition in which tear production is reduced. In essence, when the eye does not produce tears bacteria found in substances such as dust can easily enter the eye. As a result, the animal may experience eye infections which can further damage the tear glands. This can cause continuous irritation of the cornea, that in a severe state, could lead to blindness.

Symptoms

Symptoms of this condition include:

• eye infections
• a thick yellowish discharge from the eye
• lack of tears

Causes

KCS is normally caused by eye infections or damage to the eye caused by a separate problem. As a result, the tear glands are impaired and not capable of producing the correct amount of tears in order to ward off other bacteria. Certain drugs can also cause “dry eye” such as sulfonamides.

Treatment and Prevention

In order to treat KCS, eye drops are typically prescribed along with other types of ointments such as cyclosporine and tacrolimus. Surgery can also be performed; however this is in very rare and/or severe cases. In order to prevent KCS, it is imperative to clean your dog’s eyes on regular basis as well as have them checked by your vet. Be sure to consult with your vet regarding any further information about this condition.
