Introduction: Understanding Dry Eye in Dogs
Dry eye, also known as keratoconjunctivitis sicca or KCS, is a condition in which a dog’s eyes do not produce enough tears to keep the surface of the eye moist. This can lead to discomfort, irritation, and even serious complications such as corneal ulcers and blindness. While dry eye is more commonly diagnosed in humans, it is also prevalent among dogs and can occur in any breed at any age.
What Causes Dry Eye in Dogs?
Dry eye in dogs can be caused by a variety of factors, including genetics, immune system disorders, certain medications, and aging. The most common cause is an autoimmune disease called immune-mediated adenitis, which results in the destruction of the tear glands. Other possible causes include trauma to the eye, viral or bacterial infections, and chronic use of certain medications such as steroids.
Symptoms of Dry Eye in Dogs
The most common symptoms of dry eye in dogs include redness, irritation, and discharge from the eyes. Dogs with KCS may also develop corneal ulcers, which can cause pain, sensitivity to light, and cloudiness or opacity of the eye. In severe cases, dry eye can lead to blindness. Other signs to look out for include frequent blinking, pawing at the eyes, and a reluctance to open the eyes in bright light. If you notice any of these symptoms in your dog, it is important to seek veterinary care as soon as possible.
