Following is a list of the most common dog eye problems:
Conjunctivitis is one of the most common dog eye diseases, and inflammatory infiltration of the surface or parenchyma of the conjunctiva is called conjunctivitis. Generally it is simple conjunctivitis, such as foreign matters, nasolacrimal duct occlusion, medicine, trauma and other reasons. But there are also secondary diseases due to other diseases, such as infectious diseases secondary to infectious hepatitis and leptospirosis. Dogs often suffer the conjunctivitis from certain medical and parasitic diseases.
During the treatment of conjunctivitis, do not let your dog’s eyes be stimulated by strong light. Handle and clean carefully when cleaning. Keep the environment dry and hygienic, and do not touch the outside environment until your dog has recovered. Using tear drops containing anti-inflammatory ingredients can also play a preventive role to a large extent.
Keratitis refers to a dog eye disease in which corneal tissue is damaged or infected. Corneal ulcers form opaque grayish scars called corneal pannus, mostly caused by corneal trauma, foreign matters, and chemical irritation. Diseases in adjacent tissues (conjunctivitis, anterior hyperpigmentitis, etc.) can induce this disease. Keratitis is usually divided into four types: superficial, pigmented, deep and ulcerative.
The principle of treating keratitis is to elimination the cause, eliminate inflammation and analgesia, promote absorption and tissue repair, and reduce scar formation. Avoid contact with unsanitary environments.
PRA (progressive retinal atrophy) is common in many breeds of dog eye.
This disease is due to retinal degeneration. There are many different pathologies of PRA. One is dominant inheritance. The other is recessive inheritance, and the other is that no one knows whether it can be inherited so far.
All dogs affected with PRA eventually go blind. Carriers show no clinical symptoms. Symptoms are subtle, starting with night blindness, some eye dilation, to progressive blindness. It’s quite common to not notice anything is wrong until the dog is nearly completely blind. Proactive testing is always recommended, especially for breeding stock.
This is a condition where the pressure of the fluid in the eye increases until the sight is gone in that eye.
Glaucoma is one of the leading causes of blindness in dogs. Any underlying problem that increases the fluid pressure inside the eye is the culprit. Most of the time this is due to inadequate drainage of fluid from the eye (as opposed to overproduction of fluid). A few forms of glaucoma are thought to be hereditary.
Signs of glaucoma include reddened conjunctival tissue (red eye), weeping, light sensitivity, or even enlargement of the eye. As pressure increases, the pupil can become dilated and the cornea cloudy. Early diagnosis is critical to save the vision of the dog, and involves treating the underlying causes of the increased pressure if at all possible.
If you are concerned that your dog may have glaucoma, please call your veterinarian immediately because delayed treatment may cause blindness. Treatment may involve a combination of topical and oral medications, which reduces inflammation, absorbs fluid from the eye, reduces fluid production in the eye and promotes fluid drainage from the eye. In some cases, surgery may also be an option.
Cataracts are relatively common in dogs and most are hereditary. Haziness or cloudiness in the eyes in older animals is often not cataracts.
Hereditary cataracts can be found in many breeds of dogs and can be detected early in age, so all breeding stock should be screened for cataracts before being bred.
Cataracts may be stable or progressive. In the former case, you may never be aware that the dog has cataracts until or unless the dog is examined. In the latter case, the dog often adapts very well to the gradual loss in vision until a certain point is reached. General diagnosis can be done by ophthalmoscopic examination; if a more detailed examination is needed, a slit lamp examination must be performed.
For cataracts that seriously impair vision, the best and only option is Surgery. Most surgery involves the lens removing; However, implants can also be performed and used. Recovery and prognosis for these dogs are generally good.
Because of the rapid deterioration of eye problems, you should immediately take your dog to a pet hospital for treatment once you found these problems.
