Dry Eye (KCS) in Dogs

Dry eye in dogs, also known as keratoconjunctivitis sicca (KCS), is a common and often chronic condition that affects tear production. Without adequate tears, the surface of the eye becomes inflamed, irritated, and vulnerable to infection. At the Veterinary Eye Center – Connecticut, our doctors provide advanced diagnostics and individualized KCS treatment for dogs, focusing on restoring comfort and protecting long-term vision.

What Is KCS?

Keratoconjunctivitis sicca (KCS) occurs when the tear glands do not produce enough of the watery component of tears. Tears are essential for:

  • Lubricating the cornea
  • Delivering nutrients and oxygen
  • Flushing away debris and bacteria
  • Supporting a healthy ocular surface

KCS is typically a chronic inflammatory condition, often immune-mediated, in which the body attacks its own tear-producing glands. Without treatment, reduced tear production can lead to persistent discomfort, corneal damage, and vision impairment.

Ocular Surface Conditions We Treat

Symptoms of Dry Eye in Dogs

Common signs of dry eye in dogs include: 

  • Thick, sticky, or mucus-like discharge
  • Redness of the eyes
  • Squinting or increased blinking
  • Dull or dry appearance to the cornea
  • Recurrent eye infections

Because KCS is chronic, symptoms may fluctuate but rarely resolve without medical management.

Diagnosing Tear Production Problems

Accurate diagnosis is essential for effective KCS treatment in dogs. At our Connecticut location, evaluation includes:

  • Schirmer tear test, a simple and painless test that measures tear production
  • A comprehensive ophthalmic examination to assess the cornea, conjunctiva, and overall eye health

These diagnostics help confirm dry eye, evaluate severity, and identify any secondary complications such as corneal ulcers or scarring.

KCS Treatment for Dogs

The goal of dog tear production treatment is to stimulate natural tear production, reduce inflammation, and maintain a healthy ocular surface. Treatment may include:

  • Prescription anti-inflammatory eye drops
  • Tear-stimulating medications (such as cyclosporine or tacrolimus)
  • Lubricating artificial tear supplements
  • Management of secondary infections when present

Because KCS is typically lifelong, most patients require long-term therapy and periodic re-evaluation to ensure the condition remains well controlled. With consistent treatment and monitoring, many dogs maintain comfortable, functional vision.

Why Early Treatment Matters

Untreated dry eye can lead to chronic pain, corneal scarring, pigmentation, and even vision loss. Early diagnosis allows us to begin therapy before permanent damage occurs. Prompt intervention improves comfort, reduces the risk of complications, and supports better long-term outcomes.

Schedule a Consultation

If your dog has persistent discharge, redness, or signs of irritation, a thorough ophthalmic evaluation can determine whether dry eye is the cause. Our Connecticut team is experienced in diagnosing and managing KCS to help restore comfort and protect your dog’s vision.
