What is dry eye (Keratoconjunctivitis sicca)?
Keratoconjunctivitis sicca (KCS), commonly known as dry eye, is a condition where a pet’s eyes do not produce enough natural tears to keep the surface of the eye lubricated. Tears are essential for washing away debris, protecting against infection, and maintaining overall eye health. When tear production is reduced, pets may experience irritation, inflammation, excessive blinking, or thick, mucus-like discharge. Over time, dry eye can lead to corneal ulcers, pigmentation, and even vision loss if left untreated.
Why Does KCS happen?
KCS is most often caused by immune-mediated destruction of the tear glands, where the body’s own immune system mistakenly attacks the cells that produce tears. Other causes may include certain medications, infections, or breed predispositions—especially in dogs like Cocker Spaniels, Bulldogs, Shih Tzus, and Westies. Identifying and treating KCS early is critical to preventing permanent damage and maintaining a pet’s quality of life.
How Cyclosporine drops help
Cyclosporine is an immunosuppressive medication that works by calming the overactive immune response responsible for destroying tear-producing glands. When applied as an eye drop, Cyclosporine helps restore tear production and reduces inflammation in the eye. It doesn’t just relieve symptoms—it addresses the underlying immune cause of KCS, making it one of the most effective long-term treatments for dry eye in pets.
