Blue eyes or uveitis due to Blood parasite E.canis in brown mixed breed domestic dog

The ultimate goal of every dog owner is to have a happy and healthy pet, and one important aspect of a dog's well-being is their eye health. Unfortunately, there are many conditions that can affect a dog's eyes, including uveitis, a relatively common disorder.

In this article, we discuss what uveitis is and its causes and treatments.

What Is Uveitis?

Uveitis means inflammation of the uvea, so first, let’s examine the structure of the dog’s eye to understand what is the uvea and what are its parts.

The uvea is comprised of three parts:

  • Iris: The colored part of the eye that has a small black opening in the middle (pupil)
  • Choroid: The internal middle layer of the eye
  • Ciliary body: The internal continuation of the iris that produces the fluid that fills the eye

The ciliary body and the iris together make up the anterior uveal tract. Uveitis is an inflammation that can affect one or more of these parts of the uvea.

Types of uveitis depending on the area that is affected:

  • Anterior uveitis: This is inflammation of the iris and the ciliary body; it’s the most common form of uveitis.
  • Panuveitis: This is inflammation of all parts of the uvea. This is also known as true uveitis and is the most severe form of the condition.
  • Posterior uveitis: This is inflammation of only the choroid.

What Are the Signs of Uveitis?

Uveitis is a painful and potentially blinding condition in which the vascular layer of the dog's eye becomes inflamed. Several conditions can lead to uveitis, but the signs that a dog exhibits tend to be quite similar regardless of the underlying cause.

The most common signs of uveitis in dogs can include:

  • Blindness or decreased vision
  • Light sensitivity (photophobia)
  • Rubbing of the eye
  • Excessive squinting
  • Redness of the eye (bloodshot eye)
  • Bleeding inside the eye
  • Discharge
  • Excessive tearing
  • Swelling of the eyeball
  • Eye appears sunken in or smaller
  • Pupil is unusually shaped or small
  • Iris’s color might appear different or uneven
  • Eye appears dull or cloudy
  • Prominent third eyelid

Depending on the type of uveitis that the dog has and its severity, the signs can be subtle or obvious, and there may be additional signs of an underlying condition.

If your dog is showing signs of uveitis, we suggest you speak to a vet.

What Are the Causes of Uveitis?

Several conditions can lead to uveitis, but sometimes, the cause is unknown.

The following are among the more common causes of uveitis in dogs:

  • Eye injury
  • Tumors inside the eye and in other parts of the body
  • High blood pressure (hypertension)
  • Metabolic disease: Diabetes
  • Viral infections: Canine infectious hepatitis, distemper
  • Bacterial infections: Leptospirosis, Lyme disease
  • Fungal infections: Blastomycosis, cryptococcosis, histoplasmosis
  • Parasitic infections: Toxoplasmosis, leishmaniasis
  • Immune-mediated inflammation

Other factors that can contribute to uveitis include where the dog resides and their sex, age, and breed.

How Do I Care for a Dog With Uveitis?

Uveitis can lead to blindness and long-term ocular problems if left untreated, therefore the sooner your vet starts treating your dog, the better the chances of success. Treatment involves medication aimed to reduce the eye inflammation and pain and specific therapy against the problem causing uveitis. Your veterinarian may prescribe corticosteroids in the form of oral medication or eye drops or non-steroidal anti-inflammatory medication.

Most often, your dog will require prescribed eye drops or ointment and oral medication to relieve pain and inflammation, which you will need to administer at home. If the uveitis is caused by a bacterial infection, your dog will also need antibiotics, but if it is a fungal infection, your vet will prescribe an anti-fungal medication. The treatment plan will vary depending on the cause of the uveitis. Your vet may need to perform several tests on your dog to find out the cause behind your dog’s uveitis.

In some cases, uveitis can lead to serious complications such as glaucoma, retinal detachment, or lens luxation. Frequent check-ups and medications of various types are usually required during the treatment of uveitis. When uveitis is caused by a tumor, your veterinarian may recommend surgery. Even in very severe cases, and if your dog has lost their vision, your veterinarian may recommend removal of the eye, but this is always done as a last resort.

Frequently Asked Questions

How Is Uveitis in Dogs Diagnosed?

When you take your dog to the veterinarian, they will conduct a thorough physical and eye examination, which involves using some equipment, such as an ophthalmoscope or a slit lamp, to look inside the eye. This examination will help the vet make an initial diagnosis of uveitis. They will also check the intraocular pressure (IOP) levels, which can help differentiate between uveitis and glaucoma. If the IOP is low, it is likely uveitis, but if it is high, it could be glaucoma.

Additional tests, such as ultrasound, blood tests, X-rays, and urinalysis, might also be conducted to confirm or rule out any underlying conditions.

Is Uveitis an Emergency?

It's essential to treat your dog's condition as an emergency because uveitis can cause a great deal of pain, and if left untreated, there is a risk of blindness. Since there may be an underlying cause, additional treatment for this condition is necessary. Early diagnosis and immediate treatment will give your dog the best possible chance of recovery.

What Is the Prognosis for Dogs With Uveitis?

Some dogs will start to show signs of improvement within 24 to 48 hours of beginning treatment. However, the outcome is uncertain depending on the underlying cause of the problem.

If the issue is detected early, your dog is more likely to improve, but even when treatment is done quickly and correctly, it is possible for the disease to progress further and your dog may experience serious consequences. In most cases of uveitis dogs require a visit to a veterinary ophthalmologist in collaboration with your primary vet.

Conclusion

Uveitis is a serious condition that can cause severe pain and long-term consequences in canines, and it is vital to seek immediate veterinary attention if you believe that your dog might have it.

Since uveitis is typically caused by an underlying health condition, it is essential to take your dog to the vet as soon as possible so the primary condition can also be treated. When detected early, the prognosis is generally good, but severe uveitis can result in permanent blindness. Therefore, if you notice anything unusual with your dog, whether it is related to uveitis or not, it's imperative to take them to the vet without delay. This way, you can ensure that your dog remains pain-free and maintains healthy eyesight.
