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 eyelashes 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 follicles. These follicles then produce the extra hairs.

The exact cause of distichiasis is not fully understood, but genetic factors are believed to play a role. Certain breeds appear to be more susceptible to this condition, suggesting a hereditary component. In some cases, distichiasis may also be associated with other eye or skin problems.

Another possible factor that may contribute to the development of distichiasis is chronic irritation or inflammation of the eyelids. Such inflammatory conditions can alter the structure of the meibomian glands and promote the formation of hair follicles. 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 squinting, as well as rubbing the eyes with their paws.
  • Watery eyes: Excessive tearing of the eyes is a common symptom. The extra moisture may be the result of irritation from the hard hairs on the eyelid margin.
  • Redness and inflammation: The eyelids and conjunctiva may appear red and inflamed. This is a reaction to the constant irritation caused by the distichiasis 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 visit the vet?

A visit to the veterinarian is absolutely necessary if the cat shows signs of eye irritation that do not subside within a few days. Professional help should be sought immediately, especially if the cat has pain, rubs its eyes frequently, or if the condition worsens.

Another reason to see the veterinarian is the occurrence of corneal ulcers or other serious complications associated with distichiasis. Such complications can lead to permanent eye damage if not treated in time.

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 animal owners and veterinary diagnostic procedures

The recognition of distichiasis by the pet owner can be difficult, as the extra hairs 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 veterinarian will perform a thorough examination of the eyes. This includes examining the eyelids with a special magnifying glass or ophthalmoscope to identify the extra hairs. A Schirmer tear test can also be performed to assess tear production.

In some cases, the veterinarian may stain the cornea to detect possible ulcers or damage caused by the friction of the hairs. These diagnostic measures help to determine the exact cause of the eye symptoms and to create an appropriate treatment plan.

What can pet owners do and professional therapy options

As a pet owner, you can take some measures to relieve the symptoms of distichiasis in your cat until it is professionally treated. Be 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 touching or manipulating your cat’s eyes unnecessarily, 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 that you keep your cat in a stress-free environment, as stress can worsen the symptoms. Make sure that 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 treatments for this symptom. These hairs, also called trichiasis, can irritate the eye and cause 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.

In addition, research is investigating how these extra hairs 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 therapies 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 treatments 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 diet, stress, and pollution play a role in the development of these hairs. These studies may provide insight into how cat owners can reduce the risk of trichiasis by making changes in the care and keeping of their animals.

Overall, the research results show that extra cilia (ectopic cilia or distichiasis) are a complex problem influenced by a variety of factors. The advancing research in this area aims to develop more comprehensive solutions that are both preventive and therapeutic. The continuous collaboration between geneticists, ophthalmologists, and veterinarians is crucial to deepen the understanding of this condition and improve the quality of life of affected cats.

Frequently asked questions

  1. What are the symptoms of extra cilia (ectopic cilia or distichiasis) in cats? These hairs are often harder and thicker than normal eyelashes and can irritate the eye. Symptoms may include watery eyes, redness, swelling, and increased blinking or squinting. The cat may also try to rub its eyes, which indicates discomfort.

  2. How is trichiasis diagnosed in cats? The diagnosis is usually made by a thorough ophthalmological examination by a veterinarian. The veterinarian will closely inspect the cat’s eyes to determine if extra hairs are present and if they are touching the cornea.
