Eyelash Disorders in Dogs

Eyelash Disorders in Dogs

Overview:

Some dogs can develop abnormal eyelash growth that causes eye irritation, discomfort, or even serious eye damage. These conditions may look minor, but if untreated, they can lead to chronic pain or corneal ulcers. Here are the three most common eyelash-related issues:

Trichiasis

• Description: Hairs grow from their normal location around the eyes (like the face or eyelids) but are misdirected inward, rubbing against the eye surface.

• Cause: Often due to facial structure (especially in breeds with deep-set or wrinkled faces).

• Signs: Squinting, watery eyes, redness, frequent blinking.

• What to do: Regular grooming or surgical correction may be needed if irritation is severe.

Ectopic Cilia

• Description: A single or multiple hairs grow through the inner surface of the eyelid (the conjunctiva) and directly contact the cornea, often causing severe discomfort.

• Cause: Congenital (present from birth); most common in young dogs.

• Signs: Sudden blinking, pawing at the eye, pain, corneal ulcers.

• What to do: Surgical removal of the offending hair(s) is typically required to prevent permanent damage.

 Distichiasis

• Description: Extra eyelashes grow from abnormal openings along the eyelid margin, often pointing inward toward the eye.

• Cause: Abnormal development of eyelid glands (like the Meibomian glands).

• Signs: Tearing, redness, eye rubbing, mild to moderate discomfort.

• What to do: Depending on severity, treatments may include lubricating eye drops, cryotherapy, electrolysis, or surgery.

Common Signs to Watch For:

• Squinting or excessive blinking

• Red, watery, or irritated eyes

• Pawing or rubbing the face

• Discharge or cloudiness in the eyes

• Avoiding light or keeping one eye closed

What You Should Do:

If you notice any of these symptoms, don’t ignore them. Take your dog to a veterinarian or veterinary ophthalmologist for a proper eye exam. Early diagnosis can prevent pain and permanent vision damage.
