Varieties of keratitis in dogs
Veterinary specialists distinguish several varieties of canine keratitis, which are somewhat different pathogenesis, signs and peculiarities of occurrence:
- Purulent surface type of keratitis - mainly occurs due to mechanical lesions of mucous membranes. This form of keratitis is characterized by the appearance in the animal of pronounced photophobia, abundant lacrimation and the appearance of purulent discharge.
- Parenchymal keratitis - is of a microbial nature. The disease can develop against the background of canine distemper, toxoplasmosis, or in the presence of wound damage localized in the eye area. The eyes of the diseased animal begin to water very much, the cornea becomes edematous, and not its surface there are characteristic spots and dots. Quite often parenchymal keratitis is accompanied by the development of iris or conjunctivitis.
- Point keratitis is one of the rarest forms of the disease, the exact causes of which have not been fully studied to date. Characteristic symptoms include the appearance of pearly cloudy spots on the surface of the diseased eye. In this case, the animal feels normal and its visual function does not deteriorate at all.
- Phlyctenular keratitis - develops on the background of toxicity poisoning or allergic reactions. According to the doctors of veterinarians, this kind of keratitis is most affected by dogs of the collie breed, as well as the sheep dogs. The disease is characterized by the appearance on the eye cornea of large bubbles of grayish-white color. In the absence of timely treatment, they can merge and burst, resulting in the cornea acquiring a reddish-gray color. Also, phlyctenular keratitis is characterized by thickening and tuberosity of the third century.
- Ulcerative keratitis occurs against the background of a ulcerative lesion of the ocular cornea. At the same time, the surface of the eyeball becomes cloudy and clouded. With a fairly long course of the disease, it is possible to form open ulcerous surfaces in the cornea.
Methods of treating keratitis in dogs
