Eyelid Entropion in Dogs

Eyelid entropion in dogs is primarily a pathology, not an aesthetic defect.

Entropion is characterized by the altered position of the lower eyelid, where the edge of the eyelid and eyelashes come into contact with the dog's eyeball.

Signs of eyelid entropion.

Clinical manifestations of eyelid entropion include:

• tearing of the eye. Either one, if the pathology is observed in one eye, or both, if both eyes are affected.
• increased blinking by the Toy Terrier.
• atypical behavior of the pet, expressed in nervousness and anxiety.
• redness of the eyelid.
• swelling of the conjunctiva.
• narrowing of the palpebral fissure.
• clouding of the cornea.
• likelihood of serous or purulent discharge from the eyes.

In this condition, the Toy Terrier may constantly rub the affected eye if the entropion causes unbearable itching.

Upon examination of the lower eyelid in a Toy Terrier with eyelid entropion, you may see clear contact between areas of the lower eyelid and the cornea. Notably, there is no fur in this area.

Causes and consequences – keratitis, conjunctivitis.

There are two causes of eyelid entropion in dogs – primary and secondary. Primary eyelid entropion in animals arises due to heredity. Purebred dogs are prone to this condition due to inbreeding. However, the assertion of the exclusivity of the genetic congenital nature of entropion cannot be made. Currently, no gene has been identified that is responsible for the occurrence of such a disease. Therefore, primary entropion is often associated with the shape of the dog's skull, the location and shape of the eyes, the presence of folds on the head, and the degree of elasticity of the lower eyelid.

Secondary eyelid entropion is associated with mechanical factors. This pathology arises as a result of eyelid trauma, chronic eye diseases, the presence of a foreign body in the eye, or inflammation of the conjunctival membrane. There are cases of eyelid entropion occurring with significant weight loss and atrophy of the dog's chewing muscles.

A disease that provokes the occurrence of eyelid entropion in Toy Terriers is microphthalmia. Underdevelopment of certain parts of the eye with a completely or partially blind eyeball, often accompanied by agenesis, frequently becomes a cause of entropion.

The danger of this pathology lies in its adverse consequences for the Toy Terrier, namely:

• chronic irritation of the cornea.
• successful development of secondary microflora.
• severe inflammation of the cornea, leading to subsequent perforation.
• corneal ulcer.
• conjunctivitis.
• development of keratitis.
• decreased vision.

Eyelid entropion. Treatment.

The most effective option for relieving a dog from eyelid entropion today requires surgical intervention. For each breed, veterinarians have developed methods to eliminate this defect. This is explained by the peculiarities of the position of the eyelids and eyeball in each breed. Specialists, after examining your dog, create an individual plan to correct the improper position of the eyelid to return it to a normal position. The surgery is performed under general anesthesia. The only contraindication for surgical intervention is individual intolerance to anesthesia.

A specific area of the dog's eyelid is surgically removed. If the cornea is affected, doctors use tetracycline ointment or other antibacterial agents for localization. Antihistamines are prescribed if there is itching in the animal.

During the operation, veterinarians use thin material to avoid the appearance of scars on the dog. The downside is that the Toy Terrier can easily catch the suture with its claw. Therefore, for a long time after the operation, the dog must wear a special plastic collar to protect its eyes from itself.

In the postoperative period, the eyes of the Toy Terrier need to be treated with antibacterial eye drops. The sutures should be treated with a 5% alcohol iodine solution. Additionally, the lower eyelid is to be smeared with tetracycline ointment daily for a week. Gentamicin sulfate is administered intramuscularly to the dog.

After 10 days, veterinarians remove the sutures. If necessary, a repeat operation is performed, up to the complete elimination of the pathology to finally correct the position of the eyelid.

The success of the operation depends on the stage of the pathological process.

An early period or incomplete eyelid entropion is more likely to require a single surgical intervention. If the entropion is advanced and serious changes are occurring in the cornea, then after the operation, the dog will need lifelong use of special medications.

Timely detection of eyelid entropion and seeking veterinary care to correct the pathology will help your Toy Terrier avoid vision problems in the future.
