How do I check if a puppy is blind?

The intraocular pressure rises by more than 25-30 mmHg, and the normal intraocular pressure in dogs and cats is about 15-30 mmHg. An increase in intraocular pressure often causes the optic nerve to degenerate, leading to blindness. Why does this happen?

Probably due to congenital and acquired reasons, in terms of prevalence, according to statistics, about some of the animals in North American animal hospitals are treated for this disease. Which breeds, ages, and genders are particularly susceptible? Primary glaucoma is common because of certain structural abnormalities in the eye

Some polar animals such as Siberian huskies and akitas, others such as basset dogs, pine masters, poodles, Maltese dogs and Shih Tzus, etc., are usually evenly distributed at the age of 4-9 years old Lens ectopic causes secondary glaucoma common in: Boston, barley staring. West Highland White and so on.

The average distribution is 2-6 years old.

Small methods of self-diagnosis: If acute glaucoma is caused by poor drainage of aqueous humor, the dog will have painful phenomena, such as eyelids cannot be opened, red eyes, tears, head muscle tightness, etc. In chronic glaucoma, the eyes can be found to be more prominent.

In addition, the surface of the eye becomes insensitive: because the nerves are compressed and damaged. Eye pain:

This is because the increase in intraocular pressure causes nerve compression.

Cloudiness of the surface of the eyeball: due to edema of the corneal layer. Pupil dilation:

This is because the muscles and nerves that control the size of the pupil are compressed. Absent reflex to light: because of optic nerve necrosis.

Proptosis: Chronic glaucoma can cause deformation of the eye due to the accumulation of fluid in the anterior chamber. The whites of the eyes are bloodshot:

That is, the sclera area is red and swollen with each other. Laboratory diagnostic tonometry (pplanation tonometry) or schiotz tonometry (SCHIOTZ tonometry) and X-rays can help diagnose the presence of tumor factors.

How to**: Primary glaucoma is mostly bilateral and can be treated with medication or surgery**. Without proper ** or surgery within one year of onset, blindness occurs in about 40% of cases.

It's hard to check if there's something wrong with your eyes for 22 days, and you can shoot it in the eye with a flashlight, and if it doesn't respond, it's blind, but don't break it with your hands, just when it's open, shoot it in the eye with a flashlight.

Take him outside, if there are small bugs flying in front of his eyes and he turns a blind eye, there must be something wrong with his eyes.

Lisa was always in tears a while ago, and she was worried that she had a problem with her eyesight.

Later, when I took her out to sneak around, I found that she was particularly nervous about small mosquitoes and chased after her.

Even then rest assured, eyesight should be fine.

You find a ball, you bounce it up, and if the eye moves up and down with the ball, the eye is fine.

Use light to see if your pupils are narrowing.

1. Symptoms of eye blindness

When a dog's eyes are blind, the most obvious symptom is that their eyes become dull and dull. The eyes begin to become cloudy or milky white, and even the iris is missing. Consumption of water and food may decrease; Movement is getting slower and the distance traveled is shorter; It is also inevitable that you will accidentally hit furniture or handrails.

2. Causes of blindness

There are many causes of eye blindness in dogs, the most common of which are eye diseases such as keratitis, glaucoma, cataracts, retinal detachment, etc. Diseases and eye trauma, age, base response due to mutations and some diseases can also cause blindness in dogs.

In life, these diseases can be mitigated by paying attention to daily care, regular check-ups and **, which can maintain the stability of your dog's vision. There are many ways to prevent blindness in dogs, and dietary restrictions and regular check-ups can avoid the occurrence of diseases.

3. Life after blindness

While blindness is an anxiety-inducing thing, dogs can actually be trained to adapt to life after blindness and adapt well to their environment. Owners can guide the dogs through voice, using simple words and gestures to let them understand their surroundings.

If there are obstacles in the home, they must be excluded from the area where the dog is active. Keeping the layout and structure of the home unchanged can increase the owner's confidence in helping the dog adapt to the environment if the dog is blind.

4. The dog's emotional response

Dogs can easily feel lonely and helpless after losing their sight, so in their daily lives, owners need to spend more time with them and pay more attention to them. The home needs to have a quiet space to relax, where the dog can take refuge and get the necessary rest.

With a period of training, dogs can adapt to silent and dark environments, and intelligently use other senses such as smell, hearing, and touch. The owner's love and patience for them can make up for the world that the dog can't see.

When a dog is blind, its mobility will decrease, and it will become immobile and inactive, and these changes in behavior can be clearly detected by the pet owner.

When the surface of the eye is clear, free of redness, swelling, and infection, vision loss in one or both eyes is called blindness.

Cataract: Mainly due to the degeneration of the lens itself, the phenomenon of cloudiness occurs, resulting in a decrease in the amount of light entering the eyeball, resulting in vision loss and even complete blindness. 2.

The lens loses focus: When the lens in the eye needs to be removed for various reasons, it will cause the dog to be unable to focus when it is farsighted, or the lens itself will be unable to focus due to impact prolapse. In this case, only vision loss is usually caused, and blindness is not easily caused. 3.

Retinal abnormalities: There are several common diseases of the retina that are prone to such phenomena, including: sudden retinal degeneration syndrome, retinal atrophy, retinal detachment, drug poisoning (such as the anthelmintic drug ivermectin), etc. 4.

Optic nerve abnormalities: optic neuritis, optic nerve tumors, trauma, optic nerve atrophy, lead poisoning, and optic nerve pulling injuries caused by excessive exercise, etc. 5.

Central nervous system abnormalities: impaired visual areas of the central nervous system.

Symptoms of blindness in dogs.

Walking can bump into objects around you, behave quite clumsily, and be reluctant to move or move.

How to diagnose blindness in dogs.

Blood tests have found that certain eye conditions can occur along with others. For example, dogs with diabetes are prone to cataracts at the same time; In addition, if you have been to a dog with adrenal hyperfunction, you should suspect whether it is a patient with sudden retinal degeneration syndrome.

In addition, cases of lead poisoning or severe mold or bacterial infections can also lead to inflammation of the optic nerve. Ultrasound of the eye can detect the presence or absence of retinal detachment.

In the process of examination, the doctor will first use a pen lamp to understand the degree of transparency of the lens, and understand the retinal response to light, and then use an ophthalmoscope to initially determine whether it is retinal atrophy or optic neuritis. If the test is normal, there is a further possibility of sudden retinal degeneration syndrome, optic neuritis at the back of the eye, or blindness due to central nervous system damage.

Generally speaking, pet hospitals rarely measure blood pressure in dogs, but high blood pressure in dogs is a factor that causes retinal detachment.

Further tests include electroretinography and cerebrospinal fluid (CSF) to understand the true **. Tomography or MRI are two tests to help determine whether there is a central nervous system problem, but they are quite expensive.

There is no effective way to treat cases of sudden retinal degeneration syndrome, degenerative retinal disease, optic nerve atrophy and optic nerve hypoplasia.

For patients with cataracts, lens peeling or retinal detachment, surgery has a certain effect.

** After the condition.

If a dog is diagnosed with retinal atrophy or has hereditary cataracts, it should not reproduce any more children. In addition, the living environment of the dog is also very important, because the environment has many risk factors that can cause harm to the dog. For example, there are ladders with height differences, electric heaters, and sharp appliances.

Hello, if there is trauma to sudden insomnia in dogs, it is retinitis, optic neuritis, and more feeding trauma, viral infection, fungal infection, parasitic infection, poisoning, etc. can cause retinitis and optic neuritis. There is also retinal detachment, which can also be caused by trauma or retinitis. In addition, cataracts and high blood pressure may also be the cause of retinal detachment.

I want to ask if your dog is okay, and my family is like this for only five and a half months.

Hello: How many days has the dog been born? Is gray always like this? Still is? Uncle Dog.

It has been 2 years since my dog lost his sight in both eyes because of glaucoma and cataracts. The dog is very intelligent, its activities mainly rely on smell and hearing, and the eyesight is not very good, so it can quickly adapt to the familiar environment by hearing and smell, such as at home it walks freely, we often don't feel that it can't see. But it must be leashed outside, and the owner will take it away, say "up" and lift the leash slightly up when it is time to go up the stairs, and say "down" when going down the stairs, and it will know it by itself.

When encountering an obstacle, pull it on a leash and tell it the direction in which it is walking. You can let go of it in a flat and wide area, but pay special attention to its behavior, because it can't see and doesn't know the direction, so if you see it keeps going in a small circle, it means that it wants to change its position, but it doesn't know where to go, then you need to use the sound of whistling, clapping and calling it to let it know your position and come to you. Blind dogs are very timid when they come to an unfamiliar environment, and the owner should pay special attention to it.

Try not to change the layout of the home, and the position of feeding it and drinking water should be fixed; Since it can't see, it no longer chases and plays, so the amount of exercise will be limited, which requires the owner to take it around more so as not to affect health. Another thing to be careful about when walking is to avoid shrubs as much as possible, as those dwarf branches will prick its eyes. Think about these first, and you can continue to ask specific questions.

I believe that your dog will be able to live happily under your loving care!

The puppy on the side of the road was hit by a car and his eye fell out, and I sent it to the pet hospital** and his life was saved, but his eyes were blind, and I want it to be euthanized to alleviate the pain, please indicate whether it is okay to do this, I am also very entangled.

1. Causes of sudden blindness

Sudden blindness in dogs is often caused by eye diseases. For example, lens dislocation, cataract, glaucoma, retinopathy, etc. Among them, glaucoma is the most common cause, as it causes a sharp increase in intraocular pressure, which prevents the pupils from shrinking or enlarging normally, resulting in vision loss or blindness.

In addition, sudden blindness may also be associated with central nervous system diseases, such as brain tumors, strokes, meningitis, etc. These diseases may directly damage the dog's optic nerve, causing the dog to lose sight and search for the baby.

2. Ways to prevent blindness

In order to avoid blindness in dogs, we need to pay attention to the following aspects.

First of all, take your dog to the animal hospital for eye exams regularly. Early detection of eye problems, promptly**, can prevent blindness from occurring.

Second, avoid exposing your dog to excessively bright environments. Dogs' eyesight is relatively weak, and prolonged exposure to excessively bright environments can easily lead to retinal damage.

Also, don't let your dog stare at the screen for a long time, such as TV, computer, etc. This prolonged gaze can be a burden on your dog's eyes.

3. Methods of blindness

If the dog is blind, we should take it to the hospital as soon as possible**. The cause of blindness is first determined and then carried out**. If blindness is caused by an eye disease, it can be surgically implanted with an intraocular lens, fundus surgery, etc.

If blindness is caused by a central nervous system disease, a combination of ** and chemotherapy is required, including surgery, radiation**, chemotherapy and other modalities.

4. Care of blind dogs

For blind dogs, owners need to give more love and attention. First of all, it is necessary to reduce the changes in the home environment as much as possible, so that the dog can adapt to the state of blindness as soon as possible. Secondly, keep the dog on a leash when walking it so that it doesn't get lost or hit obstacles.

In addition, you can also do some simple training exercises for the dog, such as letting him learn to listen to sounds and distinguish directions, use his fingers to indicate directions, etc. This training can help the dog better adapt to the state of blindness.

There are many eye diseases that cause blindness in pet dogs, such as cataracts, loss of focus function of the lens, retinal abnormalities, in addition to optic nerve abnormalities and central nervous system abnormalities can also cause blindness in dogs. Invisible pet dogs will inevitably stumble when walking, and they will become quite cautious and even dare not walk around casually.

For dogs that have gone blind and are sure that they do not have the opportunity to regain their sight, parents should spend more time and energy on the care of daily life and sports. Creating a safe and comfortable living environment for your dog is a top priority, so that you can eliminate the fear of blindness and make it feel safe without being shocked or scared or afraid.

In addition, whether it is outdoors or indoors, it is necessary to guide the dog well, for example, when eating and eating, the pet dog should be led to the side of the food bowl, rather than letting the dog stumble to find the food bowl by itself. Especially outdoors, be sure to keep your pet dog on a leash, don't let it be lost or snatched away by bad guys, and prevent accidents such as car accidents.

Of course, if the dog's eye disease still has some hope, then please don't give up lightly, find a way for the pet dog, and strive to return the pet dog to a bright world.
