Eye infections in dogs

Ocular infections in dogs can be produced by many organisms. Also, they are derived from other systemic diseases with the ocular condition.

The eye is a very complex and sensitive organ.

To small changes inside or outside the body can be damaged easily.

The eye health of our pet should be maintained through daily cleaning with specific products or saline, as well as by removing the gummy that occurs throughout the day.

This article will talk about eye infections in dogs, some more common than others, but all equally important. To any change in the appearance of the eyes of our dog, we must go to the vet as soon as possible.

Toxocariasis ocular

The toxocariasis is a parasitic infection caused by the nematode Toxocara canis in dogs and humans, so we have a zoonotic disease.

A dog is infected with toxocara by eating infected meat or eggs of this parasite food. Eggs, reaching the intestine, cross the wall, and come through the blood to the liver.

Sometimes, however, they can overcome the barrier of the liver and travel to the brain, where meningitis – produced or eyes. Here, a single larva can develop and destroy various structures of the eyeball, which produces granulomas and chronic endophthalmitis, which is inflammation of the tissues within the eye.

Conjunctivitis eye infections in dogs

The conjunctivitis is one of the most common problems in veterinary clinics. In most cases, they are caused by eye infections in dogs. These infections may be viral, bacterial, or even by an allergic reaction type.

The conjunctiva is a translucent layer and very thin, covering the eye and inner eyelids. Due to its characteristics, this fabric is not visible unless a problem occurs. The most common symptoms of conjunctivitis are:

  • Or white sclera of the eyeball reddens by increased blood flow.
  • One occurs excessive tearing.
  • They may appear many bleary, a greenish color.
  • The dog can not open the eye. This is due to the pain caused.
  • They appear swollen eyelids, which is known as blepharitis.
  • The eye sensitivity increases, so that the light bothers you too much.

Conjunctivitis canine immune-mediated

Occasionally, conjunctivitis may be immune-mediated and related to race. The most affected breeds include the German shepherd, the long-haired dachshund, and the miniature poodle.

In these types of dogs, plasma cell infiltration can occur through the nictitating membrane or third eyelid, causing blepharitis.

Canine ehrlichiosis

The canine ehrlichiosis is a disease caused by the bacterium Ehrlichia canis, which can be transmitted by infected ticks. This condition can be fatal because it affects mainly the blood, its components, and the immune system. The main symptoms are observed in analytical anemia and leukopenia or reduction of white blood cells.

In most dogs, ocular inflammation and eyelids occur during startup and subsequent development of the disease. Finally, the disease affects other parts of the eye, such as the retina, causing pain and seriously affects the vision.

Worms eye

Canine telaziosis is caused by the worm Thelazia callipaeda. This parasite is native to Asia but has already reached different regions of Europe.

Both the adult form of these parasites as larvae live in the eyeball of domestic carnivores -Gatos and dogs- and wild carnivores. They are transmitted by arthropods.

The presence of these worms in the eyes of animals can cause varying degrees of damage:

  • excessive tearing.
  • Conjunctivitis.
  • Ocular keratitis.
  • Epiphora or blockage of tear ducts.
  • Edema, inflation, or excess fluid in the eyelids.
  • Corneal ulcers.
  • Blindness.
