We can judge the state of health and mood of the dog in her eyes. In a healthy animal eyes bright, shiny, vibrant. But, all of a sudden you notice that your petchanged opinion – it is turbid, became “extinct”.
What such a change could be the reason? This process, as well as in humans, is the character of the age or the dog sick? To answer this question it is necessary to examine the reasons that lead to the fact that the eyes swimming.
The causes of haze eyes dog
Can you imagine how the dog’s eyes? First of all, we pay attention to the iris – a circle around the pupil, usually hazel color, but some dogs have and blue.
Top iris covered with a transparent cornea and deeper located behind it ophthalmic lens or lens – a solid transparent disk through which light falls on the retina. The retina is composed of nerve cells forming the optic nerve, which is responsible for transmitting the signal from the eye to the brain.
The lens has a very important function – to change its shape allows the dog to see both near and far. In the center of the lens is located nucleus, which in the lifetime of the animal is covered with additional layers. From this layering with age the lens becomes cloudy and compacted.
Other reasons a spot on the eye may occur in which the dog has to be related to:
- hereditary factors;
- diseases such as diabetes;
- eye injuries;
- poor animal welfare, poor nutrition;
- degenerative processes in the eye;
- inflammatory and infectious diseases of the eye.
As we can see, the reasons for the cloud are many, so the first change in the eye of the dog should contact your veterinarian.
Pathology, causing the formation of cataracts
As a result, a number of inflammatory, infectious diseases or injuries involving the cornea of the eye of a dog may appear blurred cornea cicatricial so called leukoma or cataract.
Sometimes a cataract formed the puppy in utero if the mother is ill with an infection during pregnancy. Leukoma can capture all or part of the cornea and thus has the form of a greyish, shiny film covering the eye.
Nuclear sclerosis eye
We have already mentioned that throughout the nucleus of the lens becomes thicker dog’s life, and over time it becomes less transparent. This process is called nuclear sclerosis of the eye and is inherent in all dogs. Degree sclerotization core for each animal is different and depends only on the general condition of the dog, its combination of heredity and many other factors.
The first symptom of MS is dull, bluish stain that appeared next to the pupil. The defeat of the lens is shown in adult dogs older than six or seven years. In this process most commonly affects both eyes and passes slowly enough.
An animal such a state does not have a strong negative influence – he has no pain, only gradually deteriorating vision, as well as it does for a long time, the dog time to get used to the changes and live a full life.
Cataracts – a more formidable disease in which vision can lose and young animals, and in some breeds have a genetic predisposition to develop the disease, but most often it is the result of the aging of the lens.
Cataracts may develop as a consequence of disease – infection, or diabetes endoparasites and also occur after injury or eye diseases.
Conjunctivitis in dogs is accompanied by accumulation of fluid beneath the outer shell, as a result we see a dog dull eyes. Causes of conjunctivitis are very much – it’s inflammation, and allergy and foreign objects, and more.
Extremely serious disease – a glaucoma in dogs, leading to severe loss of vision and, perhaps, and a complete loss of it. First, the outer surface of the eye becomes turbid and takes on a bluish cast. Due to the fact that an eye disease accompanied by a high pressure, the dog painful sensations arise, and the eye can vary from orbit to bulge.
Primary glaucoma is an inherited and develops first in one eye, and then proceeds to the second. Secondary glaucoma develops as a consequence of an existing eye diseases.
Corneal dystrophy passed genetically. Depending on which portion of the cornea occurs change eyes are following forms of the disease:
- epithelial form – epithelium cycle is disrupted, protecting and moisturizing the cornea, the eye is observed blurred, lacrimation;
- stromal shape, which is accompanied by the deposition of salts, fat and other substances in the stroma of the eye, resulting in a corneal clouding;
- Endothelial form – pathology, in which the inner layer of endothelium, passes fluid from the anterior chamber into the stroma and causes swelling and opacification eyes, and may be accompanied keratitis – appearance of inflammatory lesions in the cornea.
When inflammation of the blood vessels are in the eye, there uevit. This complex disease is secondary and the cause of it – inflammation somewhere in the body of the dog. When uevite eyes redden and become turbid, while the animal there is a strong discomfort, excessive tearing, fear of light.
Keratitis – inflammation of the cornea, which is a consequence of infectious diseases that afflict a dog, poisoning toxins or conjunctivitis.
Treatment of any of the pathologies due to start as early as possible as described above, to prevent severe complications, time to slow down the process and save the dog’s sight.
Treatment and prevention
How to treat a cataract in a dog? Clouding of the eye – this is not an independent disease, but a symptom of some other disease. Therefore, to cope with this problem, it is necessary initially to find out what the root cause, and only then begin treatment. Make the correct diagnosis and comprehensive treatment, can only be a professional doctor, and therefore, the treatment begins with a trip to the veterinarian.
If your pet is diagnosed nuclear sclerosis or senile cataract, the hope for a full recovery is not necessary, because it is a natural process that is slowly but surely developing. However, at the first sign of disease can be carried out therapy with large doses of anti-inflammatory and antioxidant preparations that will slow down the process.
Conjunctivitis is treated by anti-inflammatory, antibacterial agents, eyewash and by laying them in ointments. In severe cases a course of antibiotics administered in injections. If allergic conjunctivitis, that exclude contact with an allergen and apply appropriate medication.
In glaucoma, the efforts aimed at physicians to snizat intraocular pressure, and remove pain in dogs. Unfortunately, cure glaucoma in dogs as in humans, it is not yet possible. If the process is running strong, the eye even have to be removed.
When degenerative corneal diseases in dogs as well try to stop the process of using various complexes of vitamins and antioxidants. If the corneal lesion has a large area, then try to fix the situation with surgery, but after it leaves scars that affect the quality of vision. This operation is expensive and does not always lead to the desired result.
Uevit treated using anti-inflammatory and antibacterial drugs, which are administered to the eye or are laid in the form of ointments.
The health of your pet in your hands, so keep an eye on them, in time, please contact your veterinarian and do not self! Eye – this is a very fine structure, which is inept when treatment can greatly suffer, so competently help your dog can only be a professional.
