What Can Cause Cyst on Cat's Eye?

Iris cysts in cats can have a variety of causes. Instead, they could be caused by a variety of different factors. The following are some possible causes of cat iris cysts:

  • Congenital: Some cats are born with iris cysts, which can be caused by genetics or developmental issues during fetal development.

  • Trauma: A traumatic injury to the eye can harm the iris, which can result in the development of a cyst.

  • Inflammation: Eye inflammation, such as uveitis, can thicken the iris and lead to the development of cysts.

  • Infection: Infections in the eye, such as feline herpesvirus or bacterial infections, can promote inflammation and cyst development.

  • Age: Due to the changes in the eye caused by aging, older cats are more likely to develop iris cysts.

  • Cancer: Iris cysts may occasionally be a symptom of a more serious ailment, such as eye cancer.


Various symptoms, some subtle and others more severe, can be brought on by iris cysts in cats. The following are some typical signs of iris atrophy in cats:

  • Change in eye color: A cyst on the iris can cause a change in the color of the affected eye.

  • Dark rings around cats' eyes: The eye may appear cloudy or hazy, especially if the cyst is large or in a prominent location.

  • Vision problems: Your cat's vision may be affected by the cyst, depending on its size and location.

  • Eye discharge: Some cats with iris cysts may experience eye discharge or tearing.

  • Eye redness: The eye may appear red or inflamed due to the presence of the cyst.

  • Squinting or rubbing of the eye: Cats with iris cysts may squint or rub their eyes due to discomfort or irritation.

Treatment For Cat Eye Cysts

The severity of the cyst and its root cause will determine the best course of action for treating and managing a cat eye cyst. Iris cysts in cats can be treated and managed in the following ways:

  • Observation: If the cyst is small and not causing any discomfort or vision problems, your veterinarian may recommend monitoring the cyst over time to ensure it doesn't grow or cause any issues.

  • Medications: To address underlying infections or ocular inflammation, vets may occasionally prescribe medicines such as antibiotics or anti-inflammatory drugs.

  • Surgery: If the cyst is large, causing discomfort or interfering with vision, surgery may be necessary to remove it. In some cases, the entire eye may need to be removed if the cyst is causing significant damage or if there is a risk of cancer.

  • Management of underlying conditions: If the cyst is caused by an underlying condition, such as uveitis or feline herpesvirus, managing the underlying condition may help prevent further cyst formation or recurrence.

Prevention Tips

Unfortunately, because iris cysts in cats can be brought on by a variety of factors, some of which are beyond our control, there is no way to guarantee that they won't develop. But there are some precautions you can take to lessen the possibility that your cat will experience iris cysts or other eye-related problems:

  • Routine veterinary check-ups: Schedule regular check-ups with your veterinarian to ensure your cat's overall health, including eye health.

  • Protect your cat's eyes: If your cat spends time outdoors, protect their eyes from dust, dirt, and other debris by keeping them indoors during windy days or using a protective cover for their eyes.

  • Good nutrition: Ensure your cat has a well-balanced diet that provides them with the necessary vitamins and minerals for good eye health.

  • Keep their living space clean: A clean living environment can help minimize the risk of eye infections that could lead to iris cysts.

  • Treat underlying health conditions promptly: If your cat has an underlying health condition that affects its eyes, such as feline herpesvirus or uveitis, work with your veterinarian to manage the condition as soon as possible.

These preventative measures will lessen your cat's chance of developing eye-related problems and help your cat stay in excellent general health, even if they may not completely avoid feline iris cysts. It's crucial to speak with your veterinarian if you have any worries about your cat's eyes.
