Eye Problems in Dogs
Eye problems in dogs range from mild irritation to painful conditions that can threaten vision. Dogs of any age can be affected, but brachycephalic breeds and dogs with inherited eye disease may be at higher risk.
Many eye problems need prompt veterinary care
Redness, squinting, cloudiness, discharge, sudden vision changes, a bulging eye, or any eye injury should be treated promptly. Severe trauma or an eye that has come out of the socket is an emergency and needs immediate hospital care.
Symptoms to Watch For
Red or bloodshot eye
Redness can happen with irritation, conjunctivitis, corneal ulcers, uveitis, glaucoma, or trauma.
Squinting or keeping the eye closed
Painful eye conditions often cause blepharospasm, light sensitivity, or rubbing at the face.
Discharge or tearing
Watery, yellow, or green discharge may point to irritation, infection, dry eye, or eyelid disease.
Cloudy or blue-looking eye
Cloudiness can be caused by corneal disease, cataracts, glaucoma, or inflammation inside the eye.
Vision changes
Bumping into objects, hesitation in dim light, or sudden blindness may occur with glaucoma, cataracts, retinal disease, or severe inflammation.
Rubbing at the face
Pawing, rubbing, or sensitivity to touch can suggest pain, irritation, or a foreign body.
What Causes Eye Problems
Eye problems in dogs are a broad category rather than a single disease. Common causes include irritation and inflammation of the conjunctiva, corneal ulcers, dry eye (keratoconjunctivitis sicca), cataracts, glaucoma, uveitis, eyelid abnormalities, trauma, foreign material, tumors, and inherited retinal disease. Some conditions are localized to the eye, while others are linked to body-wide illness such as diabetes, endocrine disease, infection, or immune-mediated disease. Because the eye can be damaged quickly, especially with ulcers or glaucoma, even mild-looking changes deserve attention.
- Trauma or scratches from play, plant material, grooming accidents, or rubbing can damage the cornea.
- Dry eye reduces tear production and can lead to redness, thick discharge, corneal ulcers, scarring, and vision loss if untreated.
- Glaucoma causes increased pressure inside the eye and is painful; it may be inherited or secondary to other eye disease.
- Cataracts may be hereditary, diabetes-related, inflammatory, traumatic, congenital, or age-associated.
- Eyelid and facial structure matter: brachycephalic dogs can be prone to exposure problems, while entropion, ectropion, distichia, and cherry eye can irritate the eye surface.
- Breed predispositions are important. Breeds reported as overrepresented for specific eye diseases include Cocker Spaniels, Basset Hounds, Beagles, Great Danes, Siberian Huskies, Shar-Peis, Pugs, Bulldogs, Shih Tzus, Lhasa Apsos, Cavalier King Charles Spaniels, and West Highland White Terriers.
How It's Diagnosed
Your veterinarian will usually start with a full history and a careful eye exam in a darkened room. They may check eyelids, tear production, corneal health, pupil responses, vision, and eye pressure. Many dogs with more serious or time-sensitive eye disease are referred to a veterinary ophthalmologist.
- Physical and ophthalmic exam to look at the eyelids, conjunctiva, cornea, lens, and internal eye structures.
- Fluorescein stain to identify corneal ulcers or surface damage.
- Schirmer tear test to measure tear production when dry eye is suspected.
- Tonometry to measure intraocular pressure and screen for glaucoma or low pressure with uveitis.
- Additional testing may include bloodwork, blood pressure measurement, imaging, culture, or electroretinography, depending on whether the vet suspects infection, systemic disease, cataracts, retinal disease, or surgery planning.
Treatment Options
Treatment depends on the underlying diagnosis and how quickly the problem is found. Many eye conditions are treated with prescription eye medications, but some require surgery or long-term management. Do not use leftover eye medication or human drops unless your veterinarian specifically advises it, because some products can worsen ulcers or other diseases.
- Conjunctivitis and surface irritation may need treatment of the underlying cause, plus prescription topical therapy and environmental management.
- Corneal ulcers often need pain control, protective care, and prescription eye medication; deep or nonhealing ulcers may require surgery.
- Dry eye is commonly managed with tear-stimulating and anti-inflammatory eye medications and usually requires lifelong treatment.
- Glaucoma needs urgent treatment to lower eye pressure and preserve comfort and vision; some cases also need surgical procedures or removal of a blind painful eye.
- Cataracts are monitored if mild, but vision-restoring treatment for significant cataracts is surgery in appropriate candidates.
- Supportive care may include an e-collar, recheck exams, referral to an ophthalmologist, and treatment of related systemic disease such as diabetes.
Eye problems can occur in puppies, adults, and seniors, though some inherited or age-related diseases are more common in specific life stages.
Keratoconjunctivitis sicca is reported most often in middle-aged dogs, though dogs of any age may be affected.
Basic exam and testing may be on the lower end, while advanced imaging, ophthalmology referral, ulcer surgery, glaucoma procedures, or cataract surgery can be much higher.
Painful or vision-threatening problems such as glaucoma, severe ulcers, trauma, or sudden blindness should be evaluated the same day.
