What is the film covering my cat's eye corner? - briefly
The film covering your cat's eye corner is likely the third eyelid, also known as the nictitating membrane. This membrane helps to protect and lubricate the eye, and it is a normal part of a cat's anatomy.

The film or discharge observed in the corner of a cat's eye is a common occurrence and can be attributed to several underlying causes. It is essential to understand that this discharge can vary in color, consistency, and frequency, each of which can provide valuable insights into the cat's overall health.
One of the most common causes of this film is epiphora, a condition where excessive tearing occurs. This can be due to various factors, including blocked tear ducts, irritants, or even allergies. When the tears overflow onto the fur around the eye, they can cause a film to form, often appearing as a moist, slightly sticky substance. Regular cleaning of the area with a warm, damp cloth can help manage the symptoms, but addressing the root cause is crucial for long-term relief.
Another possible cause is conjunctivitis, often referred to as "pink eye" in humans. This condition involves inflammation of the conjunctiva, the membrane that lines the eyelid and covers the white part of the eye. Conjunctivitis can be caused by bacterial, viral, or fungal infections, as well as allergies. The discharge in such cases can be yellowish or greenish, and may be accompanied by redness, swelling, and discomfort. Veterinary intervention is necessary to determine the exact cause and prescribe appropriate treatment, which may include antibiotics, antiviral medications, or anti-inflammatory drugs.
Dry eye, or keratoconjunctivitis sicca, is another condition that can lead to a film in the corner of a cat's eye. This occurs when the eyes do not produce enough tears to keep the surface of the eye lubricated. The resulting dryness can cause irritation and inflammation, leading to a discharge that can appear thick and mucoid. Artificial tear solutions and medications to stimulate tear production are often recommended to manage this condition.
In some cases, the film may be due to a foreign body, such as a piece of grass, dirt, or debris, lodged in the eye. This can cause irritation and excessive tearing, leading to a discharge. Gentle flushing of the eye with a sterile saline solution or visiting a veterinarian for removal of the foreign body can resolve the issue.
Regular monitoring of the cat's eye health is important. If the discharge is persistent, changes in color or consistency are noted, or if the cat shows signs of discomfort, it is advisable to consult a veterinarian. Early detection and treatment of underlying conditions can prevent more serious complications and ensure the cat's overall well-being.
