What are Iris Cysts?

An iris cyst is also commonly known as a uveal cyst. It most cases, it is a hollow structure that appears on your dog’s eye for any number or reasons. It does not hurt your dog nor does it cause any issues. However, in rare cases, it can lead to a change in behavior due to change in vision or it may obstruct the eye drainage system and can lead to related complications. If it is not causing your dog any problems, you do not have to do anything to correct it; just leave it be. If it is causing problems for your dog, certain veterinarians can perform some type of surgical correction. If your dog does have surgery, he will recover well with proper rest and treatment.

An iris cyst is common in dogs.  Dogs can be born with them, they can develop them after some form of trauma, or they can just appear with no known cause.  If your dog has one of these, no need to be alarmed.  In most cases, if does not affect your dog whatsoever.

Symptoms of Iris Cysts in Dogs

Most iris cysts do not cause symptoms in dogs.  However, the possible symptoms it could cause include:

  • Vision alteration
  • Obstruction of the drainage angle of the eye
  • Change in behavior 
  • Eventual development of glaucoma


The iris is the circular pigmented membrane behind the cornea and perforated by the pupil. This means it is the colored part of your dog’s eye.   A cyst, by definition, is an abnormal closed cavity that contains liquid or semi-solid material, lined by epithelium, and located somewhere in or on the body.  Iridic cysts in dogs are typically free floating, pigmented spheres within the anterior chamber, posterior chamber, and pupil.

Causes of Iris Cysts in Dogs

Iris cysts are commonly seen as a secondary effect of inflammation of the eye. Out of all the animal species, they are the most common in dogs. The cause of an iris cyst can also be from some form of trauma of the eye or it can be a congenital cyst that the dog is born with. But in most cases, the cause is unknown.

Diagnosis of Iris Cysts in Dogs

For the veterinarian to get a proper evaluation of your dog’s eye, there are multiple tests she may perform. The first test she will perform is the Schirmer Tear Test (STT). This test evaluates the moisture the eye is able to produce by measuring the tear production. Without proper moisture, the eye can develop a number of medical issues including ulceration and dry eye. 

Fluorescein staining may be the next test performed. The sodium fluorescein stain used will bind to unhealthy parts of the corneal stroma. If there is any blotting in the distribution of the stain, it is indicative of an abnormality. With the stain on the affected area, the veterinarian will be able to evaluate the problem easier and more thoroughly.

Another test the veterinarian may perform is tonometry. This determines the intraocular pressure (IOP), also known as pressure inside the eye. This is typically used when evaluating for glaucoma, but in this case it can be used as a rule out diagnostic. For more in depth tests, you may have to go to a specialist. They will be able to perform an ocular ultrasound, aesthesiometry, or an electroretinogram if needed.

Treatment of Iris Cysts in Dogs

Iris cysts rarely cause vision impairment so most cases do not need medical correction. If it does impair his vision, your dog may need surgery to aspirate it or to have it surgically removed. In most cases the cyst is typically a free floating hollow structure that causes no side effects. If your dog does need surgical correction, you will need to take him to a specialist. Eyes are very delicate and most general veterinarians do not have the amount of experience the specialists do.

Recovery of Iris Cysts in Dogs

If the iris cyst is not causing any issues for your dog and therefore no treatment is needed, your dog will be just fine. However, if he did get some type of surgical correction, recovery is pretty straight forward. Depending on what procedure was performed, your dog will need to be on kennel rest for the first week or so to ensure he doesn’t accidentally hurt himself. His eye may need to be covered until healed so he will need a little time to adjust to his temporary one eye view. 

He may also be sent home with medications specifically for his eye and for his system overall. He may need eye drops or ointment for a little while to ensure proper lubrication of the eye. He may also receive antibiotics as a precaution to prevent infection from developing and pain medication to help with any inflammation or irritation. Every veterinarian has their own protocol they like to follow and will recommend specific medications to send home with your dog. 

In most cases, dogs recover very well from development of an iris cyst. As stated earlier, since they typically do not cause problems, surgical correction is not recommended unless there is an issue. Since the eye is such a delicate instrument, the less treatment needed, the better.

My dog has had this on his eye for a few months now. It kind of moves around his eye depending on what way his head is leaning. I'm not certain but I think it may have gotten bigger since I've first noticed it.

So I was trimming my dogs hair around her eye and noticed a bump under her left eye. It didn’t seem to cause her any pain but when I slightly pushed on it to examine it a bit of puss did come out. She didn’t seem in any pain and hasn’t shown any signs that it has bothered her. I did drain it about a a couple of hours ago but just a bit worried that it might be something worse .

I am not sure if this is an iris cyst, it is on the eyeball it is clear and raised like a bubble, will it burst? She is a Golden Retriever and has allergies, she is 8 years old. I am reading that this is common but I don't want to dismiss this without speaking to a professional.She gets hot spots and she has a wart type thing on her bottom lip that developed recently.
Thank you,

Thank you for your email. Unfortunately, without seeing Gracie's eye, and what is going on, I have no way of knowing what it might be. It would be best to have her examined by your veterinarian, as they can see her, look at her eyes, and determine what might be going on, and if it needs treatment. I hope that all goes well with her!

Meibomian gland cysts are not uncommon especially in puppies, but would need to be seen by your Veterinarian to confirm; in a week or so you’ll need to start thinking about vaccinating so you can have your Veterinarian check at that time. Regards Dr Callum Turner DVM
