Feline Eyelash Disorders: Trichiasis, Distichiasis & Ectopic Cilia – A 2025 Veterinary Guide 🐱👁️

By Dr. Duncan Houston, BVSc

While eyelash disorders are relatively rare in cats, conditions like trichiasis, distichiasis, and ectopic cilia can cause significant discomfort and ocular complications. This comprehensive 2025 guide delves into the causes, symptoms, diagnosis, treatment, and prevention of these eyelash disorders in felines.

Understanding Eyelash Disorders in Cats 🧬

These conditions involve abnormal growth or positioning of eyelashes, leading to irritation or damage to the eye:

• Trichiasis: Normal eyelashes or facial hairs grow inwards, contacting the cornea or conjunctiva.
• Distichiasis: Extra eyelashes emerge from abnormal locations, typically from the meibomian glands along the eyelid margin.
• Ectopic Cilia: Eyelashes grow through the inner surface of the eyelid, directly contacting the eye.

Each condition can lead to varying degrees of ocular discomfort and potential vision impairment.

Recognizing the Symptoms 🔍

Symptoms may vary depending on the specific disorder but can include:

• Excessive tearing (epiphora): Due to irritation.
• Squinting or blinking (blepharospasm): Indicative of discomfort.
• Redness and inflammation: Around the eye area.
• Corneal ulcers: Resulting from constant friction.
• Pawing at the eye: A sign of irritation or pain.

Early detection of these signs is crucial for effective treatment.

Diagnosis 🩺

Diagnosing eyelash disorders involves a thorough veterinary examination:

• Ophthalmic examination: Using magnification to inspect the eyelids and eyelashes.
• Fluorescein staining: To detect corneal ulcers or abrasions.
• Schirmer tear test: Measuring tear production to assess eye health.
• Intraocular pressure measurement: Evaluating the pressure within the eye.

Accurate diagnosis guides the development of an appropriate treatment plan.

Treatment Options 💊

Treatment depends on the specific disorder and its severity:

• Trichiasis: Trimming or removing misdirected hairs; surgical correction if caused by structural abnormalities like entropion.
• Distichiasis: Plucking offending hairs; cryotherapy or electrolysis for permanent removal; surgical options in severe cases.
• Ectopic Cilia: Surgical removal of the aberrant hairs and their follicles; may require corneal repair if ulcers are present.

Post-treatment care includes administering prescribed medications and regular follow-up visits to monitor healing.

Prognosis 📈

The prognosis varies based on the disorder's severity and promptness of treatment:

• Favorable prognosis: For mild cases treated early.
• Guarded prognosis: For cases with corneal ulcers or scarring.
• Recurring issues: Possible if underlying causes aren't addressed.

Regular monitoring and follow-up care are essential to prevent recurrence.

Preventive Measures 🛡️

Preventing eyelash disorders involves proactive health management:

• Regular grooming: Keeping facial hairs trimmed to prevent irritation.
• Routine veterinary check-ups: Early detection of any ocular abnormalities.
• Breeding considerations: Avoiding breeding cats with known eyelid or eyelash disorders.

Implementing these measures can reduce the risk of eyelash disorders in cats.

When to Consult a Veterinarian 👩‍⚕️

Seek veterinary attention if your cat exhibits:

• Persistent eye discharge or tearing
• Squinting or frequent blinking
• Redness or swelling around the eyes
• Pawing at the eyes or signs of discomfort

Prompt evaluation can prevent serious complications and ensure your cat's ocular health.
