If a cat's eyes are covered with a film? - in detail
If a cat's eyes are covered with a film, several significant changes and potential issues can arise for the feline. This condition, often referred to as "dry eye" or keratoconjunctivitis sicca, is characterized by the absence of adequate tear production, leading to insufficient lubrication and protection of the eyes.
One of the primary symptoms of this condition in cats is excessive squinting or blinking. The cat may exhibit a persistent discharge from the eyes, which can be watery or mucoid in nature. This discharge is an attempt by the body to compensate for the lack of tears and provide some level of moisture to the eye surface. Additionally, the eyes might appear red and inflamed due to the irritation caused by the dryness.
In more advanced cases, the cornea can become cloudy or develop ulcers. This is a serious complication that requires immediate veterinary attention. The cat may also experience discomfort or pain, which can be evident through changes in behavior such as reduced activity levels or increased irritability.
The underlying causes of this condition can vary. It might be due to an autoimmune disorder where the body attacks its own tear glands, a congenital defect, or even certain medications that affect tear production. Additionally, environmental factors such as dry air or exposure to irritants like smoke can exacerbate the symptoms.
Diagnosis typically involves a thorough examination of the eyes and possibly a Schirmer Tear Test (STT), which measures the rate of tear production. Treatment options depend on the severity and cause of the condition. In mild cases, artificial tears may be prescribed to supplement the natural tears. For more severe or chronic conditions, immunosuppressive medications might be necessary to control the autoimmune response. In some cases, surgery can be an option to permanently relieve the symptoms by redirecting tear production from another area of the eye.
Regular follow-ups with a veterinarian are crucial for monitoring the condition and adjusting treatment as needed. Owners should also ensure that their cat's environment is humidified if necessary, and they should be cautious about exposing the cat to potential irritants. With proper care and management, many cats can lead normal lives despite having dry eye.
