Chorioretinitis in Dogs: Causes, Symptoms, and Treatment What Is Canine Chorioretinitis and How Can It Be Treated?

Chorioretinitis in Dogs: Causes, Symptoms, and Treatment

Dogs' eyes can develop chorioretinitis, a disorder that, if ignored, can cause vision loss. However, there are ways to treat and even prevent the condition. We discuss this eye condition in canines further in this article.

Chorioretinitis is a disease of the retina of the eye that can lead to vision loss if left untreated. It is a word used to indicate inflammation of both the retina and the choroid, the layer of the eye that feeds the retina (the light-sensitive layer of the eye that converts light into electrical signals). Various disorders, including bacterial or viral infections, immune-mediated diseases, and ocular trauma, can cause chorioretinitis.

This article will examine canine chorioretinitis's causes, symptoms, and various therapies.


There are many potential causes of retinal degeneration in dogs. Some of the most prominent causes include:

  • Infections: Bacterial, viral, fungal, or parasitic illnesses include canine distemper, Lyme disease, Rocky Mountain spotted fever, toxoplasmosis, or leptospirosis.

  • Autoimmune illnesses: Diseases such as uveodermatological syndrome, Systemic lupus erythematosus (SLE), Rheumatoid arthritis, or Granulomatous meningoencephalomyelitis are examples of immune-mediated illnesses (GME).

  • Trauma: Eye trauma can cause inflammation and damage the choroid and retina. This could be caused by a foreign body in the eye, a piercing or traumatic injury, or chemical exposure.

  • Genetic predisposition: Certain dog breeds, including Collies, Australian Shepherds, and Shetland Sheepdogs, may have a higher chance of getting chorioretinitis.

  • Unknown causes: In certain situations, chorioretinitis may be categorized as idiopathic since its etiology is unknown.


The symptoms of retinal atrophy in dogs can vary based on the underlying cause and the gravity of the inflammation. A few signs and symptoms of retinal abnormalities in dogs include:

  • Alteration in vision

  • Eye discharge and redness

  • Night blindness in dogs

  • Sensitivity to light

  • Changes in behavior

  • Changes in appetite or weight loss

Treatment and Management Options

The treatment and management options for progressive retinal atrophy in dogs depend on the underlying cause and severity of the inflammation. A few popular forms of treatment are:

  • Medications: Based on the cause of the inflammation, your veterinarian may prescribe antibiotics, antiviral or antifungal medications to treat any underlying infections. Immunosuppressive medications like Furosemide may also be recommended if an immune-mediated disease causes inflammation.

  • Eye drops: Eye drops containing corticosteroids or other anti-inflammatory drugs could be administered to treat ocular irritation.

  • Surgery: Surgery can be required in extreme circumstances to remove the damaged tissue and stop the eye from suffering additional harm.

  • Nutritional supplements: Nutritional supplements such as omega-3 fatty acids, antioxidants, and vitamins may be recommended to aid eye health and minimize inflammation.

  • Management of the environment: In some circumstances, environmental variables may be causing inflammation. Your physician could advise modifying your dog's surroundings, such as limiting their exposure to allergies or irritants.

  • Follow-up care: To keep track of your dog's development and modify therapy as necessary, it's crucial to schedule routine checkups with your veterinarian.

In addition to medication, a few management techniques can enhance your dog's quality of life and help stop additional eye damage. They consist of the following:

  • Eye safety: Dogs with chorioretinitis might be more prone to an eye injury. By utilizing protective eyewear or avoiding potentially harmful activities, it is crucial to safeguard their eyes from damage.

  • Monitoring vision changes: Regularly monitoring your dog's eyesight will assist in identifying any abnormalities in their vision early on and enable rapid treatment.

  • Maintaining a healthy diet: A balanced diet can help support your dog's general and eye health.

  • Providing a safe and comfortable environment: Your dog will experience less stress and recuperate faster if you give him a secure and comfortable environment.

Prevention Options

Preventing retinal degeneration in dogs can be challenging as the condition has many different causes. However, there are several things you can do to lessen the possibility that your dog may have chorioretinitis. They consist of the following:

  • Immunizations: Ensuring your dog has all the necessary shots can help prevent illnesses that could cause chorioretinitis.

  • Regular veterinary examinations: Chorioretinitis can be avoided by having routine veterinary checkups, which can aid in the early detection of any underlying health conditions.

  • Environmental management: You may help avoid eye irritation by limiting your dog's exposure to potential irritants or allergens, such as dust, pollen, or certain chemicals.

  • Eye protection: You may assist in preventing damage to your dog's eyes by using protective eyewear or restricting activities that could hurt them.

  • Genetic testing: If you're looking to adopt or buy a purebred dog, genetic testing can help you determine whether the dog has a genetic tendency to chorioretinitis or other eye conditions.

While chorioretinitis in dogs may not be entirely preventable, following these recommendations will help lower the likelihood of your dog's ailment and enhance its general health and quality of life.
