What Is Uveitis?

Uveitis is an inflammation that affects the vascular layer of the eyeball, known as the uvea, which is made up of the iris, ciliary body, and choroid. This inflammation may also extend to other parts of the eye, such as the cornea, optic nerve, blood vessels, and retina.

This condition can occur in both dogs and cats, regardless of age, and may affect one or both eyes. In most cases, identifying the exact cause requires a thorough diagnostic protocol, including a comprehensive evaluation by a specialist to rule out systemic diseases such as Leishmaniasis.

Although most cases of uveitis can be treated and controlled, it is crucial to start treatment as early as possible to prevent complications. In more severe cases, vision loss may occur—and it could be irreversible.

Types of Uveitis (based on the affected area):

  • Anterior uveitis: when only the iris or both the iris and ciliary body are inflamed.
  • Posterior uveitis: when only the choroid is inflamed.
  • Panuveitis: when the entire uveal tract (iris, ciliary body, and choroid) is affected.

What Are the Symptoms?
Symptoms can appear suddenly and worsen quickly, although in some cases, they may develop gradually. Sometimes, signs of uveitis are only detected during a thorough ophthalmic examination.

The most common symptoms include:

  • Squinting or blepharospasm – involuntary contraction of the muscles around the eye.
  • Photophobia – sensitivity to light.
  • Excessive tearing.
  • Changes in the appearance of the eye – such as cloudiness or a hazy look.
  • Redness of the conjunctiva – often mistaken for conjunctivitis.
  • Miosis – constricted pupil.
  • Low intraocular pressure.

Remember: early treatment is essential to prevent permanent damage.

What Is the Treatment?
Treatment is focused on reducing inflammation, alleviating pain, and preventing long-term complications. This typically involves the use of anti-inflammatory medications, immunosuppressants, and/or mydriatic-cycloplegic agents to control inflammation and avoid further issues. In certain cases, corticosteroids and specialized eye drops may be used.

If the uveitis is caused by an underlying condition or parasitic infection, treatment will also address the root cause using appropriate medications.

At IVeM, we offer advanced diagnostic tools for the assessment and monitoring of this condition in our patients. If you suspect your animal might be affected, schedule an appointment for an eye exam.
