Have you noticed your cat squinting or rubbing their eye more than usual? Maybe their eye looks cloudy, or they seem uncomfortable in bright light. These could be signs of glaucoma, a serious eye condition that can lead to vision loss if left untreated. Understanding the symptoms, causes, and treatment options can help you protect your cat's eyesight and overall quality of life.

⚠️ What to Watch For

Glaucoma in cats can develop gradually or appear suddenly, making it crucial to recognize the warning signs early. While cats are experts at hiding pain, there are some symptoms you can look for:

  • Cloudy or bluish appearance in one or both eyes
  • Excessive tearing or discharge
  • Redness or swelling in the eye
  • Squinting or keeping the eye closed
  • Pupils of different sizes (one may appear larger)
  • Rubbing or pawing at the face
  • Sensitivity to light
  • Loss of vision (bumping into objects or acting disoriented)

These symptoms can be subtle at first, but they often worsen over time. If you notice any of these signs, it's best to act quickly to prevent further damage.

🔍 Possible Causes

Glaucoma occurs when there’s an imbalance in the production and drainage of fluid inside the eye, leading to increased pressure. This pressure can damage the optic nerve and retina, resulting in vision loss. There are two main types of glaucoma in cats:

  • Primary glaucoma: This is rare in cats and is typically inherited. Certain breeds, like Siamese and Burmese cats, may be predisposed.
  • Secondary glaucoma: This is more common and occurs as a result of another eye condition. Common causes include:
    • Uveitis (inflammation inside the eye)
    • Eye trauma or injury
    • Lens luxation (displacement of the lens)
    • Tumors in or around the eye
    • Infections

Understanding the underlying cause of your cat’s glaucoma is essential for determining the best treatment approach.

✅ What You Can Do at Home

While glaucoma requires veterinary care, there are some steps you can take to support your cat’s eye health at home:

  • Observe your cat closely for any signs of eye discomfort or changes in appearance.
  • Keep their eyes clean by gently wiping away discharge with a damp, clean cloth.
  • Minimize stress and ensure they have a quiet, comfortable environment.
  • Provide a balanced diet to support overall health, including eye health.

It’s important to note that home care alone is not enough to treat glaucoma. If you suspect your cat has this condition, prompt veterinary intervention is critical.

💡 When to Call a Vet

If you notice any signs of glaucoma in your cat, don’t wait to seek professional advice. This condition can progress quickly, and early treatment can make a significant difference in preserving your cat’s vision. Call your vet or book an online consultation if you see:

  • Cloudiness or redness in the eye
  • Sudden changes in vision (e.g., bumping into furniture)
  • Persistent squinting or pawing at the face
  • Swelling around the eye

Your vet may recommend tests like tonometry (to measure eye pressure) or imaging to diagnose the condition. Treatment options may include medications to reduce pressure, anti-inflammatory drugs, or surgery in severe cases.

According to VCA Animal Hospitals, prompt intervention is crucial to prevent irreversible damage and maintain your cat’s quality of life (source).
