Dog's dry eye disease has confirmed the basic and inflammatory nature of stubborn lacrimal glands, and cannot be completely cured. So what causes can cause dog dry eye disease? I will tell you that only by finding the roots can it be effectively prevented.
1. Drug causes: sulfonal drugs (some "people often used by people") can cause dogs' dry eye disease.
2. Caused by surgery: The third eyelid gland (cherry eye) caused by the removal of surgery caused dry eye.
3. Spontaneous and senile nature: The cause of the dry eye disease is related to the age of animals and the tear glands gradually shrink.
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 of the eye sockets or under the 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 tear glands and the third eyelid glands, which will cause the loss of temporary or permanently secreting tearr function.
7. Congenital or genetic cause: The incomplete development of congenital glands will often occur in the young or young adult dogs of mini dog breeds, such as Chihuahua and Yorksia dogs. 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) , Passea, Beijing Dog, Boston Sirstion, Western Highland Stalk Dog, Charles Hounds, Lhasa Dogs, British Kakako, US Coca dogs and British bullfighting dogs.
8. Craninal Nerve v lack of sensory nerves on the surface of the eyeball.
9. Craninal Nerve vii in lack of paranasia sensory nerves.
10. Other reasons: There are many unknown or unknown factors.
