The 3-year-old bullfighting child had a third eyelid hyperplasia surgery for both eyes two years ago. Recently, the owner found that the secretions in both eyes increased. He came to the clinic and found severe dry eyes. The remaining years of Chou and Chou kids have to rely on artificial tears to accompany them - Doctor Jiang Tao of Qujing, Yunnan Province, continues to be cared for by a film formed by tears. It has a wetting effect, helping to heal eye trauma and prevent eye infections. Just like the " "hydrating mask" on the skin, it locks in moisture, keeps moisturizing and blocks invasion. Tears that moisturize the eye surface are secreted by the lacrimal glands, and the outer layer of the tear film "water-locking" is mainly composed of lipids secreted by the meibomian glands. Without this layer of lipid, tears evaporate quickly and easily dry your eyes. When the quality and quantity of this layer of tears are abnormal, it will cause damage to the tear film, causing eye discomfort or visual dysfunction, such as dry eyes, photophobia, wind-fearing, redness and itchy eyelids, heavy secretions, blurred vision, foreign body sensation, unknown tears...
Sciatria of dogs have been proven to be the basic of stubborn degenerative and inflammation of the lacrimal gland and cannot be completely cured. So what are the causes of Sciatria of dogs? Let me tell you that only by finding the root cause can you effectively prevent it.
Raising a pug is not easy. These 6 problems will make the owner so hard that he doesn't want to raise a dog.
1. Drug causes: Sulfonamide drugs (eye drops commonly used by some people) can cause eye dryness in dogs.
2. Cause of surgery: eye saryngosis caused by surgical removal of the third eyelid gland (cherry eyes).
3. Spontaneous and elderly causes: The cause of saryngology in dogs is related to the aging of animals and the gradual atrophy of the lacrimal glands.
4. Autoimmunity causes: Up to 30% spontaneously serpentine serpentine is related to autoimmunity destroying the lacrimal glands and the third eyelid glands. Among the cases of saryngology in the ophthalmology clinic of the National Taiwan University Animal Hospital, there are relatively high proportions of immunity abnormalities, including allergic constitution or folliculosis infection.
5. Trauma caused by trauma or under the eye socket: The secretion of tears becomes abnormal due to the trauma caused damage to the lacrimal gland and the third eyelid gland, or the nerves that control the lacrimal gland and the third eyelid gland, causing damage to the secretion of tears.
6. Canine distemper: Canine distemper virus can affect the lacrimal glands and the third eyelid glands, thereby causing temporary or permanent loss of tear secretion.
7. Congenital or genetic causes: Congenital acinar hypoplasia often occurs in young or young adult dogs of mini breeds, such as Chihuahua and Yorkshire terrier. In addition, there are dog breeds that are genetically prone to saryngeal symptoms (but the age of onset is not certain), which is often related to autoimmune attack on the lacrimal gland. Dog breeds include Marcis, Yorkshire Terrier, Shih Tzu (detailed introduction), Puggo, Pekingese, Boston Terrier, Western Highland Gentle, King Charles Hound, Lhasa, British Cocker Spaniel, American Cocker Spaniel and British Bulldog.
8. Craninal nerve V is caused by lack of sensory nerve distribution on the surface of the eye.
9. Craninal nerve VII is caused by the lack of parazygotic sensory nerve.
10. Other causes: There are many unconfirmed or unknown factors that have been raised.
