What causes a cat to have film over its eyes? - in detail
The presence of a film or discharge over a cat's eyes can be attributed to several underlying conditions. One of the most common causes is an infection, particularly conjunctivitis. Conjunctivitis is an inflammation of the thin layer of tissue that lines the eyelids and covers the white part of the eye. It can be caused by viruses, bacteria, or allergens, leading to redness, swelling, and a discharge that can form a film over the eyes.
Another possible cause is dry eye syndrome, which occurs when the cat's tear glands do not produce enough tears to keep the eye lubricated. This condition can result in a thick, mucoid discharge that may form a film on the surface of the eye. Dry eye syndrome can be caused by various factors, including age, autoimmune diseases, or other health issues affecting the cat's overall well-being.
Eye injuries and foreign bodies can also lead to the formation of a film over a cat's eyes. If a cat sustains an injury to the eye or has a foreign object lodged in it, the body may respond by producing excess mucus to protect the eye from further damage. This mucus can form a thick film that obscures vision and requires prompt veterinary attention.
In some cases, systemic diseases such as feline immunodeficiency virus (FIV) or feline leukemia virus (FeLV) can cause ocular symptoms, including the formation of a film over the eyes. These viruses weaken the cat's immune system and make it more susceptible to infections that can affect the eyes.
Regardless of the underlying cause, it is crucial to consult with a veterinarian if you notice a film or discharge over your cat's eyes. A thorough examination and appropriate diagnostic tests can help determine the exact cause and allow for timely and effective treatment. Ignoring the issue could lead to complications, including permanent damage to the eye or loss of vision.
