Yes, cats can get eye worms.
Eyeworms, specifically Thelazia californiensis and Thelazia callipaeda, are parasitic nematodes (roundworms) that can infect the eyes of cats, dogs, other animals, and even humans. These worms are typically found in the western United States and parts of Asia.
What are Eyeworms?
Eyeworms are slender, whitish worms, usually measuring between 0.25 and 0.75 inches (7 to 19 millimeters) in length. They are characterized by their rapid, snake-like movements across the surface of the eye.
How Do Cats Get Eyeworms?
The primary vectors for eyeworm transmission are certain species of flies. The flies feed on the tears of infected animals, ingest the eyeworm larvae, and then transmit the larvae to a new host when they feed on their tears.
Symptoms of Eyeworm Infection in Cats
- Squinting or excessive blinking
- Redness and inflammation of the conjunctiva (the membrane lining the eyelid and covering the white part of the eye)
- Excessive tearing
- Discharge from the eye
- Presence of visible worms on the surface of the eye or under the eyelids
- Pain and discomfort
Diagnosis and Treatment
A veterinarian can diagnose eyeworm infection through a thorough eye examination. The worms are often visible to the naked eye. Treatment typically involves manual removal of the worms by the veterinarian, followed by the use of anti-parasitic medications to kill any remaining larvae.
Prevention
Controlling fly populations can help reduce the risk of eyeworm infection in cats. Regular veterinary checkups are also important for early detection and treatment of any eye problems.
