Analysis of the causes of red blood in the eyes of dogs

Causes of red bloodshot eyes in dogs

Clinical studies have found that there are many causes of bloodshot eyes in dogs. For example, eye diseases (conjunctivitis, etc.); canine distemper; colds and fever; dry eye syndrome; getting angry, etc., the effects of these conditions can cause bloodshot eyes in dogs. If it is found that the dog’s eyes are not right, it is best to take the dog for an eye examination, and scientific treatment can only be carried out after the cause is determined.

Eyeball prolapse is one of the causes of bloodshot eyes in dogs. The normal eyeball is embedded in the eye socket, the main structure of the eye socket is bone, the purpose is to protect the eyeball. However, under certain conditions, the eyeball will run out of the eye socket, causing serious eye damage. The causes of this disease in dogs, such as genetics, head trauma, dog bites, and bone fractures around the eye sockets due to various reasons, can also cause eye prolapse.

Dry eye can also easily cause bleeding in the eyes of dogs. Long-term lack of tear fluid causes dry and inflammatory diseases of the cornea and conjunctiva. In addition to moisturizing the cornea and washing away foreign bodies, tear fluid also has enzymes and antibodies to prevent pathogens from entering. If the eyeball loses the infiltration and protection of tear fluid, the cornea It is prone to thickening and unevenness, and even ulcers or fibrosis. In severe cases, it can cause blindness.

As the saying goes, “the eyes are the windows of the soul”, this is true for people, and it is true for pet dogs. Pay attention to protect the dog’s eye hygiene and health in life, clean the eyes of the dog regularly, and drop eye drops on it regularly to prevent bacterial infection and protect the dog’s eye health

What to do if the dog’s eyes are red

First, be clear about the reason

Some people say that a little blood streak is normal, and if there is a lot of eye feces, it is a symptom of illness. Dogs can be seen when the lights are turned off at night, because dogs evolved from wolves, and wolves are used to night activities. This should be observed. The dog has red blood streaks for one or two days and then recovers. There is no problem, but if it appears for a long time, it will be troublesome.

Second, because of the important diseases common in dogs’ eyes

1. Eyeball prolapse

The normal eyeball is embedded in the eye socket, the main structure of the eye socket is bone, the purpose is to protect the eyeball. However, under certain conditions, the eyeball will run out of the eye socket, causing serious eye damage. Why do you get this disease?

Because of genetics, some dogs with shallow eye sockets (such as Pekingese and Xi Tzu) often cause eyeball prolapse due to excessive agitation. In addition, head trauma, dog bites and bone fractures around the eye sockets due to various reasons can also cause eye prolapse.

How to deal with urgently

The eyeball is an organ that needs moisture at any time. If this happens, in addition to sending to the doctor immediately, if you can’t get it to the doctor immediately, you should follow the following principles

1. Adequate moisturizing and cleaning: Use clean water (boiling water, mineral water) or physiological saline (contact lens rinse) to moisten and clean the eyeballs, and keep the eyeballs moist at all times.

2. Strictly prohibit the dog from scratching the eyeball: Because the dog itself will be quite uncomfortable when the eyeball is prolapsed, the reflex action is to fiddle with the prolapsed eyeball with the foot, causing secondary injuries.

3. Strictly prohibit pressure on the eyeball. When the eyeball is prolapsed, it is often accompanied by corneal ulcers or perforations. If pressure is applied, it often causes the fluid in the eyeball to leak and cause irreversible damage to the eyeball.

Third, dry eye in dogs

Long-term lack of tear fluid causes dry and inflamed cornea and conjunctiva. Why do we get this disease? In addition to moisturizing the cornea and washing away foreign bodies, tear fluid also has enzymes and antibodies to prevent pathogens from entering. If the eyeball loses tears The infiltration and protection of the cornea is prone to thickening and unevenness, and even ulcers or fibrosis. In severe cases, it can cause blindness. Long-term bacterial infection of the eyes will cause the destruction and blockage of the lacrimal glands. Certain viral infections such as canine distemper can also cause dry eye. Certain drugs also reduce the secretion of tears: Atropine, Phenazopyridine, Sulfadiazine.

The removal of the third eyelid is also prone to dry eye, because the third eyelid can secrete about 40% of tears. Which breeds, ages, and genders are particularly prone to the disease? Some breeds of dogs have common lacrimal defects: Beijing and Pugs. In addition, older animals are more prone to lack of tears. ,

Fourth, the small method of self-diagnosis: The dog is prone to blinking, scratching the eyes with the forelimbs, the surface of the eyes loses luster, and the eyes are covered with small, dry and hard eye feces. In the early stage of the disease, the surface of the eyeball will become cloudy and dry, and then there will be fibrosis and even blepharospasm.

Laboratory diagnosis tear test strips, corneal staining test and biopsy are several common methods. How to treat?

1. Artificial tears: This is the most troublesome item in treatment, because it is often necessary to help dogs with artificial tears at intervals of 2 hours. Many people often cannot continue due to various factors, leading to treatment failure.

2. Antibiotic treatment: It can control the bacteria on the eyeball to damage the surface of the eyeball.

3. Artificial lacrimal gland, by surgical method, part of the saliva thread is used as lacrimal gland.

4. Drugs that stimulate tear secretion: Pilocarpine.

5. If cataract is difficult to cure

Fifth, prevention is the first priority. Dogs get slight red blood streaks. The owners should pay attention to see if the dog food they feed is too irritating. If the dog eats it with unbalanced nutrition, is there any other food? Some nutritional products that are good for eyesight, Gudeng Blueberry Essence is essential at home.
