Cataract in dogs: symptoms, treatment
Cataract is a clouding of the lens of the dog's eye, which eventually leads to blurred vision or to more serious complications - glaucoma and blindness.
A small cataract does not greatly affect vision, but it must be constantly observed, because the denser and thicker it becomes, the greater the probability of reaching blindness.
Causes of Cataract in Dogs
Cataract can develop as a result of eye trauma(Mechanical, chemical or thermal), some general disease (eg, diabetes mellitus), poisoning, with age. Still, the most common causes are hereditary conditions, that is, a genetic predisposition. Poodles, cocker spaniels, terriers, miniature schnauzers and golden retrievers are more prone to cataracts.
This disease from birth can be present or develop even between one and three first years of the dog's life.
Symptoms of cataract in dogs
When cataracts, the eyes of the dog lookBluish-gray or cloudy. In general, it is normal that the lens of the eye becomes less transparent with age than in youth. This condition is called nuclear sclerosis, and it practically does not threaten the sight of the animal and does not require treatment.
Nevertheless, the visual acuity of the animal decreases with cataracts. And in order not to miss the development of cataracts, any opacification of the dog's eye should be the reason for contacting the vet.
If cataract is not treated, it can slip out of the tissues that hold it, and block the natural outflow of fluid in the eye. This often leads to the development of glaucoma and permanent blindness.
Treatment of cataract in dogs
Conservative treatment of cataract in dogs can be carried out only at the very beginning of the disease to prevent the progress of the disease. However, it is impossible to cure this disease with the help of medicines and diet.
Often sight lost due to cataracts,Can be restored through surgical intervention. At the same time, the lens is removed, replacing it with an acrylic or plastic lens. The artificial lens of the eye becomes a permanent part of the eye and does not require any care. It is not felt and does not cause any inconvenience to the animal.
In general, this is a fairly successful operation, butRequires long-term postoperative care. However, the disease with diabetes mellitus will complicate the treatment of cataracts. Therefore, in the first place, it is necessary to treat diabetes.
