What to do if one of a cat's pupils is larger than the other? - briefly
If one of a cat's pupils is larger than the other, it is crucial to remain calm and observe the cat for any additional symptoms. Immediately consult a veterinarian, as this condition, known as anisocoria, can indicate underlying health issues that require prompt medical attention.

When observing a cat with one pupil larger than the other, it is crucial to understand that this condition, known as anisocoria, can have various underlying causes. The first step in addressing this issue is to remain calm and assess the situation carefully. Pupil size is regulated by the autonomic nervous system, and changes in pupil size can indicate neurological or ocular issues. It is essential to note that while some causes of anisocoria are benign, others may require immediate veterinary attention.
One of the most common benign causes of anisocoria in cats is a condition known as third eyelid prolapse or "cherry eye." This occurs when the gland of the third eyelid prolapses and becomes visible, causing one eye to appear smaller than the other. While this condition may cause some discomfort, it is typically not an emergency and can be treated by a veterinarian. However, if the third eyelid is not properly repositioned, it can lead to chronic irritation and potential infections.
Another possible cause of anisocoria is trauma to the eye or head. Cats are curious animals and can easily injure themselves while exploring. Trauma can lead to swelling, bleeding, or damage to the nerves that control pupil size. If trauma is suspected, it is important to keep the cat calm and avoid any further injury. Immediate veterinary care is necessary to assess the extent of the damage and provide appropriate treatment. In severe cases, surgery may be required to repair damaged tissues or correct structural abnormalities.
Neurological conditions can also result in anisocoria. Conditions such as brain tumors, strokes, or infections can affect the nerves that control pupil size. These conditions are serious and require prompt veterinary attention. Symptoms to watch for include lethargy, seizures, loss of balance, and changes in behavior. If any of these symptoms are present, it is crucial to seek veterinary care immediately. Early diagnosis and treatment can significantly improve the prognosis for these conditions.
In some cases, anisocoria may be a side effect of certain medications. Some drugs, particularly those affecting the autonomic nervous system, can cause changes in pupil size. If a cat is on medication and develops anisocoria, it is important to consult with a veterinarian to determine if the medication should be adjusted or discontinued. Always follow the veterinarian's advice regarding medication changes.
Infections and inflammations of the eye can also cause anisocoria. Conditions such as uveitis, glaucoma, or conjunctivitis can lead to changes in pupil size. These conditions may cause additional symptoms such as redness, discharge, and pain. Veterinary treatment may include antibiotics, anti-inflammatory medications, or other therapies to address the underlying cause of the infection or inflammation.
It is important to monitor the cat's overall behavior and health. In some cases, anisocoria may resolve on its own without intervention. However, if the condition persists or if the cat exhibits any other concerning symptoms, veterinary care is necessary. Regular check-ups and prompt attention to any changes in the cat's health can help ensure early detection and treatment of potential issues.
In summary, anisocoria in cats can have various causes, ranging from benign conditions to serious neurological issues. It is essential to assess the situation carefully and seek veterinary attention if necessary. By understanding the potential causes and symptoms, cat owners can take appropriate steps to ensure their pet's health and well-being. Always prioritize the cat's comfort and safety, and consult with a veterinarian for professional advice and treatment.
