If you notice any of the following signs, schedule an appointment right away:

Redness
Cloudiness
Squinting or excessive blinking
Ocular discharge (watery, mucus, or pus)
Pawing or rubbing at the eye
An eye that appears larger than normal
Sudden vision loss (bumping into objects, difficulty catching treats, disorientation)
Early evaluation can protect your pet’s eyesight, comfort, and overall quality of life.
Common Causes of Vision Loss in Dogs & Cats
Pets can develop many of the same eye diseases as humans. At Virginia Veterinary Centers - Short Pump, we diagnose and treat a wide range of ocular conditions, including:
Corneal ulcers
Dry eye (KCS)
Cataracts
Glaucoma
Below is an overview of these common conditions.
Corneal Ulcers in pets: The cornea is the clear front surface of the eye that allows light to enter. Because it is exposed, it is vulnerable to:
Scratches
Chemical burns
Foreign objects
Trauma
The cornea contains many pain receptors, making ulcers extremely uncomfortable.
Signs of a corneal ulcer:
Redness
Squinting
Tearing
Light sensitivity
Diagnosis involves applying a special fluorescent dye that highlights damaged areas. Treatment depends on the ulcer’s severity and may include medications or surgical intervention. Prompt treatment is critical to prevent deeper injury or vision loss.
Dry Eye (Keratoconjunctivitis Sicca or KCS) in pets: Dry eye occurs when the tear glands do not produce enough tears. Most cases are immune-mediated, though certain medications may also contribute to the problem and other causes are less common but possible.
Breeds commonly affected by dry eye:
Cocker Spaniels
Bulldogs
West Highland White Terriers
Lhasa Apsos
Shih Tzus
Signs of dry eye:
Thick, chronic mucus discharge
Redness
Discomfort
Dull or cloudy appearance
Without proper treatment, dry eye can lead to corneal scarring and impaired vision. Diagnosis is simple and involves measuring tear production (known as a Schirmer tear test). Treatment is typically lifelong and includes medications to stimulate tear production and lubricate the eyes.
Cataracts in pets: A cataract is a clouding of the lens inside the eye. The lens normally focuses light onto the retina. When it becomes cloudy, vision becomes impaired.
Common causes:
Genetics (most common)
Diabetes
Age-related changes
Breeds at higher risk of developing cataracts:
American Cocker Spaniels
Havanese
Miniature Schnauzers
Boston Terriers
Bichon Frise
Silky Terriers
Poodles
Cataracts may start small but can progress and significantly affect vision.
The only effective treatment for vision-impairing cataracts is surgery performed by a veterinary ophthalmologist. The cloudy lens is removed and replaced with an artificial intraocular lens - using techniques similar to human cataract surgery. Our team at Virginia Veterinary Centers - Short Pump can evaluate whether your pet is a candidate for cataract surgery.
Glaucoma in pets: Glaucoma occurs when fluid inside the eye (aqueous humor) cannot drain properly. This leads to increased intraocular pressure, which damages the retina and optic nerve. Glaucoma can cause permanent blindness quickly and is considered a medical emergency.
Signs of glaucoma in pets:
Redness
Cloudiness
Squinting
Pain
Dilated pupil
Enlarged eye (in chronic cases)
A veterinarian can measure eye pressure using a tonometer to confirm the diagnosis. Glaucoma requires lifelong management with medications to control pressure. Even with treatment, some pets may lose vision, making early detection essential.
Vision loss and blindness in pets
Learning that your pet has lost vision can feel overwhelming. Vision loss may occur suddenly (within hours) or gradually over years.
Signs of vision loss:
Confusion or anxiety
Bumping into objects
Reluctance to use stairs
Difficulty finding food or treats
Depending on the cause, treatment may restore vision. A complete ophthalmic examination at Virginia Veterinary Centers- Short Pump can determine available options for your furry friend. If vision cannot be restored, most dogs and cats adapt remarkably well using their strong senses of smell and hearing.
