In my opinion, the dog's eye disease should belong to dry eye. This disease is due to insufficient secretion of tears, so that the cornea and conjunctiva can not be wetted by tears, leading to chronic progressive lesions of the cornea or conjunctiva.
The factors of insufficient tear secretion are congenital insufficient tear secretion or senile lacrimal gland atrophy. Acquired, that is, secondary, there are many factors, among which, viral diseases, such as canine distemper, or drugs, will reduce tear secretion; Another example is head trauma or chronic bacterial infection of conjunctiva, which can also damage lacrimal gland and dominate the nerve of lacrimal gland; At the same time, it will also cause diseases due to vitamin A deficiency and ovariectomy. When this disease occurs, dogs begin to have eyelid spasm, eyes can't open and tears are secreted. Sticky glue will be stored on the surface of the eyeball, and then the eyelids will be difficult to close. The conjunctiva will be red and thickened, the corneal epithelial layer will be thickened, the pigment will be deepened, and the cornea will be cloudy. Some people will have corneal defects. At this time, the dog's nose is dry.
A moist and dry tear layer should be obtained first, and 0.5%- 1% methylcellulose can be applied to the eyes.
Activating the lacrimal gland is also essential. 2% pilocarpine hydrochloride was mixed into the food by 2 drops per 10- 15 kg body weight and fed to it once a day. You can observe the medication time. If you get better, you can stop taking the medicine, which usually lasts at least one month.
In order to control infection, some antibiotic eye drops are also used, such as gentamicin and chloramphenicol. However, when using these drugs, one of them only takes about a week at most to avoid drug resistance.
I understand your love and true feelings for dogs, which is an unsurpassed pure friendship between people in modern society. It is even more impossible to measure it with money. It is precisely because of the limited medical equipment that I lost my beloved baby. Even if I can cure the disease, I think of the help network to seek some health for the dog. How I hope that all dogs can be examined and treated conditionally after they get sick! If this is unrealistic, then I still hope that all dogs can have owners like you. Well done! ......
