When dogs's eyelids are turned inward, the eyelashes tend to rub against the cornea, causing ulcers. Often accompanied by severe pain and discomfort. If your dog's eyes are constantly tearing and pus coming out, you should see a veterinarian immediately. Once you have the disease, surgery is required. Entropion is the turning of the eyelid edge inward. More common in Pekingese, Shar Pei, and Setters. What are the causes of inversion of the dog's eyelid and how to treat it?

1. Developmental Deficient Entropion

and Variety is related to heredity, and the exact heredity law is unclear. Shar-Pei, Chow Chow, St. Bernard Breeds such as , Labrador, Great Dane, and small poodles are prone to occur. Facial and eye configuration may be a causative genetic defect. It is generally considered to be a simple dominant inheritance, and the inheritance pattern is difficult to determine. Generally, both eyes are affected, different varieties, and different degrees of varus. For example, the Great Dane has large and deep eye sockets, which lack sufficient support for the eyelids, which in turn can cause entropion.

2. Spasmodic blepharoplasty

Conjunctivitis, foreign body, dry keratoconjunctivitis, trichiasis, dillion, eyelash proneness and Corneal ulcer and other secondary orbicularis muscle spasm and entropion. Trigeminal neuralgia can cause blepharospasm and varus. Eyelid trauma or inflammation causes fibrosis to cause eyelid deformation and inversion. It usually occurs on one eyelid and can occur in dogs of any age.

3. Acquired Entropion

Entropion caused by loss of orbital fat or muscle atrophy. Loss of muscle tone can also occur in older dogs.

Treat according to the cause

1. Developmental Defective Entropion

Surgical correction is possible in most cases. However, surgery is generally ideal at 4-6 months of age or when facial features have matured. Shar-Pei dogs can be temporarily sutured on the eyelids at 3 weeks of age to prevent severe corneal lesions. Permanent surgical correction illustration.

2. Spasmodic blepharoplasty

Most of the causes were eliminated, and the varus was improved. In order to reduce the irritation to the eyeball, soft contact lenses or temporary eyelid sutures can be placed, and the sutures are removed in 2-3 weeks. If there is no effect, blepharoplasty is required.

3.Acquired blepharoplasty

Acquire surgical correction according to the degree of entropion correction. Lateral canthal fixation is generally used to reduce palpebral fissures to correct blepharoplasty. Flaps of the same size were incised on the upper and lower eyelids of the lateral canthus. The upper eyelid flap was excised, and the lower eyelid flap was retained and sutured to the eyelid skin defect.

4. Postoperative care

Due to swelling in the first few days after surgery, the eyelid was slightly everted. Apply antibiotic ointment or eye drops to the affected eye 3-4 times a day. The neck must wear an Elizabethan ring to prevent damage to the eye. The sutures are removed 10-14 days after surgery.
