Dutch Maoli Dog (detail introduction)
The popularity of dry eye disease is the disorders of tears. After this disease is obtained, it is usually rarely shed tears or even without tears, so it is a more painful thing. This kind of problem occurs in dogs, so what causes the dog's dry eye disease? Let's do a simple understanding together.
1. Drug cause: sulfonal drugs (some "people often used by people") can cause dogs' dry eye.
2. Caused by surgery: The third eyelid gland (cherry eye) was removed due to the removal of surgery.
3. Spontaneous and seniority: The cause of the dry eye disease is related to the age of animals and the gradually shrinking of the tear glands.
4. Causes of autoimmune: Dry eye caused by as high as 30%of spontaneous spontaneousness is related to autoimmune destruction of lacrimal glands and third eyelid glands. In the case of dry ophthalmosis in the Ophthalmology Clinic of the National Taiwan University of Animal Hospital, there are a significant and higher proportion of abnormal immunity, including allergies or hair follicle infections.
5. Invasiveness in the eye sockets or eye sockets causes the lacrimal glands and the third eyelid glands due to trauma, or the nerve in charge of the tear glands and the third eyelid gland is damaged, which makes the secretion of tear fluid abnormal.
6. Causes of canine plague: The canine plague virus can affect the loss of the tear glands and the third eyelid glands, which will cause the loss of temporary or permanently secreting tears.
7. Congenital or genetic cause: The development of congenital prostrates often occurs in the young or young adult dogs, such as Chihuahua and Yorksham. In addition, there are dog breeds with inheritance of dry eye (but the age of onset is not necessarily), which is often related to autoimmune attack lacrimal glands. The dog species include Marzis dogs, Yorkshire dogs, and Shih Shi (details) (For details introduction), Palan, Beijing dog, Boston stalk dog (detail introduction), Western highland stalk dogs, Charles king hunting dog, Lhasa dog, British Kako dog, US coca dog and British bullfighting dog.
8. The lack of sensory nerve distribution on the surface of the eyeball.
9. Tear glands lack the distribution of sub -sexual nerves.
10. Other reasons: There are many unknown or unknown factors.
