Glaucoma In dogs – Symptoms – Causes – Treatment.

Glaucoma illness is the most severe disease in dogs, which causes blindness in dogs. Glaucoma in dogs can be diagnosed when an eye injury is first observed.

In dogs with glaucoma, one or both eyes might swell and result in blindness. Dogs suffering from glaucoma need an immediate cure to avoid serious complications.

Glaucoma In dogs:

Glaucoma is a prevalent affliction in dogs, but the good news is that you can easily protect your pet. Some of the problems related to glaucoma are also not visible and can have some severe implications.

If your dog is experiencing any glaucoma symptoms, you should take him to the vet immediately. If you wait until your dog develops the disease, the risks are higher and will be even more dangerous.

Glaucoma in dogs is often hard to detect, but if the dog is in pain, talk to your vet. Sometimes dog having glaucoma could end up with an eye infection, brain damage, heart disease, respiratory failure, etc.

There are two major types of Glaucoma in dogs:

  1. Primary Glaucoma
  2. Secondary Glaucoma

Primary Glaucoma in dogs:

Primary glaucoma is caused by excessive growth of the cells in the retina or the middle layer of the eye.

The retina is responsible for receiving light and other stimuli, and in healthy dogs, it slows down in size until it eventually stops growing.

When primary glaucoma goes untreated, the retina might eventually shrink to the point where vision in the affected eye becomes severely impaired.

If there is no glaucoma treatment in dogs, the dog may not live for more than a few years.

Secondary Glaucoma In dogs:

Secondary glaucoma in dogs is the rarest type of glaucoma. This type is caused by damage to one of the two optic nerves (the optic nerve in the eye that carries  signals to the brain from the back of the eye and the optic nerve in the ear that carries messages from the brain to the back of the eye).

Acute glaucoma in dogs:

Acute glaucoma in dogs is a condition that affects a large number of dogs each year.

This type of eye disease can be either congenital or acquired. Because glaucoma is not a life-threatening disease, it is generally overlooked by owners.

The best treatment is surgery if detected early enough. However, in most cases, the disease remains diagnosed and untreated, resulting in blindness in many dogs.

The good news is that any canine with any amount of visual impairment can benefit from glaucoma surgery.

Sudden onset glaucoma in dogs:

sudden onset glaucoma in dogs can strike your furry pet at any time. This condition is  the leading causes of blindness and eventually leads to death.

This condition’s underlying purpose is either a tumor on the optic nerve or a build-up of fluid in the middle ear.

When these conditions are the cause, there is no treatment for sudden onset glaucoma in dogs.

However, if your dog develops sudden onset glaucoma due to the middle ear problem, several treatment options are available.

These treatments should be explored with your vet to determine which course of action is most likely to help your dog’s condition.

First, any sudden onset of glaucoma in dogs can be treated by treating the underlying cause. The main cause of this condition is tumors on the optic nerve.

If the tumor is removed, you may find that the situation is relieved. If not, the problem can be treated with surgery.

Treatments range from pain medications to surgery. Both are effective in relieving the symptoms associated with this condition.

End stage Glaucoma in dogs:

End-stage glaucoma in dogs occurs As a result of chronic Intraocular pressure (IOP) elevation. IOP is considered an important factor in the evaluation of End-stage glaucoma in dogs.

Other signs and symptoms include decreased aqueous production, ciliary body atrophy, and atrophy of the phthisis bulbi (Phthisis bulbi is a shrunken eye caused by severe eye inflammation, injury or illness.

Beginning signs of glaucoma:

Beginning signs of glaucoma in dogs are not easy to identify by the pet owner itself; however, it is easily identified by an experienced veterinarian.

Early diagnosis is extremely important as it could save your dog’s eye and even lead to successful treatment.

The early onset of the disease means that the damage is advanced and does not have time to progress.

This means that chance of a more rapid deterioration of the eye increases. These are the initial signs of glaucoma in dogs that you should be aware of.

If you notice them in your dog, make sure to visit your veterinarian as soon as possible

Initial signs of glaucoma in dogs

  • loss of appetite,

  • loss of appetite.
  • Weight loss.
  • Vision problems.
  • Constant thirst and pale skin. 
  • May cause weakness and ataxia, as well as drooling.
  • Seeing halos around lights. 
  • Being unable to see objects at certain distances.
  • Change in vision, loss of ability to concentrate. 
  • Loss of balance.
  • However, due to the sensitive nature of glaucoma in dogs, symptoms may also be confused with eye infections, viral infections, allergies, or the flu.

What causes glaucoma in dogs?

When you are looking for the cause of glaucoma in dogs, you will find a lot of different types of eye conditions.

This condition is caused by inadequate drainage of aqueous fluid; it is not caused by the overproduction of fluid. 

The following are considered the main causes of glaucoma in dogs.


Uveitis is the inflammation of the uvea (severe intra-ocular infections )— it consists middle layer of the eye and iris, ciliary body, and choroid.

The causes of Uveitis may have, including eye injury and inflammatory diseases. Resulting in debris and scar tissue blocking the drainage angle.

Anterior dislocation of the lens:

 Anterior dislocation of the crystalline lens is uncommon, but some times can cause severe problems, such as secondary glaucoma, corneal edema, and endothelial cell damage.

In the dislocation of the lens, the lens falls forward and blocks pupil so that fluid is trapped behind the fallen lens.


Tumors can cause physical blockage Between the cornea and the anterior surface of the attached margin of the iris) called the iridocorneal angle 

Ophthalmology or Intra-ocular bleeding:

It may be the result direct injury to the eye) or medical illness. Continuous and severe bleeding may cause high pressures inside the eye, leading to glaucoma and blindness.

Damage to the lens:

Damage lens can cause an inflammatory reaction resulting in swelling and blockage of the drainage angle.

Treatment of glaucoma in dogs:

Treatment of primary glaucoma:

This treatment can include intraocular lens (IOL) implantation. If surgery is performed, the doctors will have to remove a portion of the retina and replace it with an IOL.

Also, the dog will be treated for blood clotting problems and possible bleeding.

Treatment of secondary glaucoma:

This type of treatment is difficult. Even if the IOL was surgically placed, the retina might not stop shrinking, and growth might begin in the other eye.

Secondary glaucoma should include a high dose of steroids. But, a poor diet and lack of exercise could make the condition worse. In this case, surgery is usually the only treatment option.

  • Glaucoma can be controlled through exercise and diet. Proper nutrition is crucial to the health of the retina growth. Although a dog’s diet is important, it should also contain plenty of vitamin A, iodine, and calcium.
  • It is very important to take in a good amount of protein as well because the dog’s body needs a good supply of irreducible minimal essential thiamine. The diet should also contain calcium and iron. Because protein and iron are necessary for the retina to grow, a high protein diet will also be beneficial.


Is a dog with glaucoma in pain?

When asked if a dog with glaucoma is in pain, the answer to that question can vary. It depends on the dog’s condition and on how the dog reacts to his or her particular circumstances.

A dog with glaucoma is always in pain, no matter what, even though the eye may be weak.

The fact that the eye is weaker does not mean that the dog is in pain. In a dog with glaucoma, the dog may have some problems with his vision, but he or she will still perceive things around him or her with just as much clarity as a person with good eyesight.

A dog with glaucoma that experiences difficulty with vision can again experience pain and discomfort, and when the dog is extremely sick, other symptoms also make the dog in distress.

While there are medications available to help a dog with glaucoma deal with his or her pain, these medications can also cause even more severe health problems, like blindness.

Is glaucoma in dogs curable?

There are many questions about Glaucoma in dogs that pet owners often wonder if the disease is curable.

The answer to this question is a little bit more complicated than most people would think, as there are several types of Glaucoma in dogs, including the acute and chronic types.

When it comes to pet owners trying to decide whether they should keep their pet from suffering from Glaucoma, the answer largely depends on the kind of Glaucoma that their dog has.

Chronic Glaucoma causes your dog to suffer from blinding headaches and blurred vision. There are no apparent symptoms in this condition, and your dog may never show any signs of illness at all.

This is one of the most severe Glaucoma in dogs as if left untreated; the disease can damage the optic nerve.

Fortunately, there are various treatments available for this condition, but the prognosis is not suitable if your dog has developed Glaucoma.

What causes sudden glaucoma in dogs?

Why is it that a fine earlier dog in his life suddenly starts to lose vision in one eye? Can you imagine how stressful this can be for your dog? He may not notice his condition or hope that it will go away.

But if you pay attention to your dog, you will see that he is missing many things in his life. Most people tend to blame their pet’s condition on something other than a dog’s health.

You may think that a dog getting infected with a disease such as leukemia is the reason, but it is rare, and it is not the cause of sudden glaucoma in dogs. The most common cause of sudden glaucoma in dogs is a buildup of pressure inside the eye.

This pressure happens when a dog’s tear duct fills up with more fluid than it should. Sometimes the fluid backs up into the eye, causing a build-up that has to be removed.
