Why are my cat's eye whites red? - in detail
Redness in a cat's eye whites, also known as scleral redness, can be indicative of several underlying conditions. It is essential to understand the potential causes to ensure appropriate care and treatment. One common reason for this symptom is conjunctivitis, an inflammation of the conjunctiva, the thin tissue that covers the white part of the eye and the inner surface of the eyelids. Conjunctivitis can be caused by viral, bacterial, or fungal infections, as well as allergies. Symptoms often include redness, discharge, and swelling. Another potential cause is corneal ulcers, which are open sores on the surface of the eye. These ulcers can result from trauma, such as scratches from a cat's own claws or foreign objects, and can lead to significant discomfort and redness.
Eye injuries, including scratches or punctures, can also cause redness. Such injuries may result from fights with other animals, accidents, or contact with sharp objects. Trauma to the eye can lead to bleeding and inflammation, making the whites of the eyes appear red. Furthermore, glaucoma, a condition characterized by increased pressure within the eye, can cause redness along with other symptoms such as squinting, cloudy eyes, and changes in pupil size. Glaucoma requires immediate veterinary attention to prevent permanent damage to the eye.
Dry eye, or keratoconjunctivitis sicca, is another condition that can lead to redness. This occurs when the eyes do not produce enough tears, leading to irritation and inflammation. Dry eye can be caused by various factors, including autoimmune diseases, certain medications, or aging. In some cases, redness in the eyes may be a sign of a more systemic issue, such as an infection or disease affecting the entire body. For example, feline infectious peritonitis (FIP) and feline leukemia virus (FeLV) can sometimes present with ocular symptoms, including redness.
Eye infections, such as those caused by the feline herpesvirus or Chlamydophila felis, can also lead to redness. These infections often result in additional symptoms like discharge, squinting, and corneal ulcers. Allergies, either environmental or food-related, can cause red, itchy eyes in cats. Allergic reactions can lead to inflammation and irritation, making the whites of the eyes appear red. Additionally, certain types of tumors or cancers affecting the eye can cause redness. These neoplastic conditions may present with other symptoms, such as swelling, discomfort, and changes in eye appearance.
It is crucial to seek veterinary care if you notice redness in your cat's eye whites. A thorough examination by a veterinarian can help determine the underlying cause and appropriate treatment. Treatment options may include antibiotics for bacterial infections, antiviral medications for viral infections, anti-inflammatory drugs for inflammation, or surgery for more severe conditions like tumors or glaucoma. Regular check-ups and prompt attention to any changes in your cat's eyes can help maintain their overall eye health and prevent potential complications.
