Non-urgent see a veterinarian within 2–3 days
ORANGE for rubbing, blepharospasm, corneal opacity/injury, or chronic tearing (friction/trichiasis/distichiasis-like). RED for corneal ulcer/suspected vision loss.

Definition
Extra cilia (ectopic cilia or distichiasis) that are coarser than normal eyelashes are referred to as “distichiasis” in cats. These hairs grow from the Meibomian glands on the eyelid margin and can cause irritation to the eye.
Can Occur with the Following Diseases:
Basics and possible causes
Distichiasis is a condition in which extra eyelash hairs grow from the eyelid margin glands. These hairs are often stiffer and can irritate the cat’s sensitive eye. The condition occurs when the Meibomian glands, which normally produce sebum to lubricate the eyelids, transform into hair follicle. These follicle then produce the extra hairs.
The exact cause of distichiasis is not fully understood, but it is believed that genetic factors may play a role. Certain breeds appear to be more susceptible to this condition, indicating a hereditary component. In some cases, distichiasis may also be associated with other eye or skin problems.
Another possible factor that can contribute to the development of distichiasis is chronic irritation or Inflammatory conditions of the eyelids. Such Inflammatory conditions can alter the structure of the Meibomian glands and promote the formation of hair follicle. However, it is important to note that not all cats with inflamed eyelids necessarily develop distichiasis.
Typical accompanying symptoms
- Eye irritation: Cats with distichiasis often show signs of eye irritation. This can manifest as frequent blinking or winking, as well as rubbing the eyes with their paws.
- Watery eyes: Excessive tearing of the eyes is a common symptom. The extra moisture can be the result of irritation from the coarse hairs on the eyelid margin.
- Redness and Inflammatory conditions: The eyelids and conjunctiva may appear red and inflamed. This is a reaction to the constant irritation from the distichial hairs.
- Corneal ulcers: In severe cases, the friction of the hairs can lead to corneal ulcers, causing pain and potentially impairing vision.
- Behavioral changes: Cats with eye discomfort often show behavioral changes, such as lethargy or decreased playfulness, as the constant irritation causes discomfort.
When to see a vet?
A visit to the vet is absolutely necessary if the cat shows signs of eye irritation that do not subside within a few days. Especially if the cat is in Pain, frequently rubs its eyes, or if the condition worsens, professional help should be sought immediately.
Another reason to visit the vet is the occurrence of corneal ulcers or other severe complications associated with distichiasis. Such complications can lead to permanent eye damage if not treated promptly.
Even if the cat shows signs of visual disturbances, such as bumping into objects or not recognizing familiar people, an immediate visit to the veterinarian is necessary to rule out serious problems.
Symptom recognition for the pet owner and veterinary diagnostic procedure
Detection of distichiasis by the pet owner can be difficult, as the Extra cilia (ectopic cilia or distichiasis) are often very small and located close to the eyelid margin. However, careful observation of the cat’s behavior can provide clues. If the cat blinks frequently or rubs its eyes, this could indicate distichiasis.
The vet will perform a thorough eye examination. This includes examining the eyelids with a special magnifying glass or an ophthalmoscope to identify the Extra cilia (ectopic cilia or distichiasis). A Schirmer tear test may also be performed to assess tear production.
In some cases, the vet may stain the cornea to detect possible ulcers or damage caused by the rubbing of the hairs. These diagnostic measures help to determine the exact cause of the eye symptoms and to create an appropriate treatment plan.
What the pet owner can do and professional therapy options
As a pet owner, you can take some measures to alleviate the symptoms of distichiasis in your cat until it receives professional treatment. Make sure to keep your cat’s eyes clean and free of irritants. You can do this by gently wiping the eyes with a soft, damp cloth.
Avoid unnecessarily touching or manipulating your cat’s eyes, as this could worsen the irritation. If the cat tries to rub its eyes, you should try to prevent this to avoid further damage.
It is important to keep your cat in a stress-free environment, as stress can worsen the symptoms. Make sure your cat’s environment is free of dust and other potential irritants that could further irritate the eyes.
Although these measures can help to temporarily relieve the symptoms, it is crucial that the cat is examined and treated by a veterinarian to address the underlying cause of the distichiasis and prevent long-term eye damage.
Outlook on current research
Research into Extra cilia (ectopic cilia or distichiasis) in cats that are coarser than normal eyelashes focuses on understanding the causes and potential treatment methods for this symptom. These hairs, also called trichiasis, can irritate the eye and lead to discomfort. Current studies are investigating genetic factors that may contribute to the development of these hairs, as well as environmental factors that influence their occurrence.
A significant area of research is the investigation of the genetic predisposition of certain cat breeds to trichiasis. Researchers have begun to perform genome sequencing to identify genetic markers associated with the development of these hairs. By understanding the genetic basis, scientists hope to develop preventive measures and targeted breeding strategies to minimize the risk in affected breeds.
Furthermore, research is examining how these Extra cilia (ectopic cilia or distichiasis) affect the quality of life of cats. Studies are addressing the extent to which the hairs can impair vision and whether they cause long-term eye damage. Initial results suggest that chronic irritation from these hairs can lead to Inflammatory conditions and, in severe cases, corneal ulcers.
Current developments in veterinary treatment include innovative techniques for removing the bothersome hairs. Laser therapy and cryotherapy are two methods currently being tested to permanently remove the hairs without damaging the surrounding tissue. These approaches offer promising results and could become standard therapy in the future.
Another research aspect is the investigation of the relationship between environmental factors and the occurrence of trichiasis. Researchers are analyzing whether factors such as nutrition, stress, and environmental pollution play a role in the development of these hairs. These studies could provide insights into how cat owners can reduce the risk of trichiasis through changes in the care and husbandry of their animals.
Overall, research findings show that Extra cilia (ectopic cilia or distichiasis) are a complex problem influenced by a variety of factors. Ongoing research in this area aims to develop comprehensive solutions that are both preventive and therapeutic. Continuous collaboration between geneticists, ophthalmologists, and veterinarians is crucial to deepen the understanding of this condition and improve the quality of life for affected cats.
