My cat has different pupils, what's wrong? - in detail
If your cat has pupils of different sizes, a condition known as anisocoria, it could indicate an underlying health issue that requires prompt attention. Anisocoria itself is not a disease but a symptom of various potential problems. One common cause is trauma or injury to the eye, which can result in swelling, bleeding, or damage to the structures controlling pupil size. Infections, such as uveitis or conjunctivitis, can also lead to inflammation affecting the iris and pupil response. Neurological issues are another significant concern; conditions like Horner's syndrome, brain tumors, or damage to the nerves controlling the eyes can disrupt normal pupil function. Additionally, systemic diseases such as high blood pressure, diabetes, or toxicity from certain substances may manifest as anisocoria. It is crucial to observe your cat for other symptoms, such as changes in behavior, vision problems, discharge from the eyes, or signs of pain. A veterinarian should evaluate your cat to determine the exact cause through a thorough physical examination, possibly including blood tests, imaging, or specialized eye tests. Early diagnosis and treatment are essential to address the root cause and prevent further complications. Ignoring this symptom could lead to worsening of the condition or permanent damage, so seeking professional veterinary care is strongly advised.
