If you want to know more about glaucoma, kindly keep reading the article. In this article, you will find answers to the questions like, is glaucoma hereditary, treatment options for treatment (medications) of glaucoma in humans, and pets such as dogs, and cats.

What is glaucoma all about?

Glaucoma is an eye condition that can damage the optic nerve in the eye. The optic nerve is responsible for providing the visual details to your brain from your eyes. Glaucoma most likely results in increased pressure inside your eye (increased intraocular pressure). 

Can glaucoma cause blindness

The increased pressure causes damage to the optic nerve, leading to loss of vision or blindness if not treated. If you start the treatment early, you may be able to prevent vision loss and slow the progression of the disease.

Is Glaucoma Hereditary in Humans?

According to the World Health Organization, glaucoma is the second leading cause of blindness across the globe. Various risk factors may cause glaucoma, such as: 

  • Age 
  • Eye problems 
  • Medical history 
  • Use of medication 
  • Ethnicity 
  • Family history 

So, to answer the simple question, Is glaucoma hereditary? Yes, it is. 

Glaucoma Is It Hereditary

Some types of glaucoma could run in families. If someone in your family (especially your father or grandfather) had open-angle glaucoma, you might develop the condition.

Is Glaucoma Genetic Or Hereditary

The difference between hereditary and genetic diseases is: hereditary diseases have the potential of being transferred from one generation to another. On the other hand, genetic diseases can either be hereditary or not, but mutational changes in the genome will occur.

So, yes. Glaucoma may be genetic or hereditary. 

Is Any Glaucoma Hereditary?

There are mainly two types of glaucoma: open-angle and angle-closure. The most common type of glaucoma is open-angle, which is believed to be hereditary. If someone in your immediate family has it, you are at a much higher risk than the others. Family history increases the risk of glaucoma 4-9 times.

Is Congenital Glaucoma Hereditary

Congenital glaucoma is a type of glaucoma that is present at birth. It is typically diagnosed in the first year. Yes, congenital glaucoma is hereditary. There is a 25-50% chance of a child developing congenital glaucoma if either of the parents has glaucoma.

Is Glaucoma a Hereditary Disease

The most common type of glaucoma is open-angle, which is believed to be hereditary. If someone in your immediate family has it, you are at a much higher risk than the others. Family history increases the risk of glaucoma 4-9 times.

Is Pseudoexfoliation Glaucoma Hereditary

Pseudoexfoliation glaucoma is also known as pseudoexfoliative glaucoma, a type of open-angle glaucoma. It is caused by the abnormal accumulation of proteins in the eye’s drainage system. Yes, genetics is a risk factor for pseudoexfoliation glaucoma. Some people carry (the LOXL1) gene, which is a risk factor.

Is Narrow Angle Glaucoma Hereditary

Narrow-angle glaucoma is less common but can be hereditary. Usually, narrow-angle glaucoma occurs suddenly without showing any symptoms.

Is Low Pressure Glaucoma Hereditary

Low-pressure glaucoma is also a type of glaucoma. It is an optic neuropathy with chronic loss of retinal cells due to genetic hypersensitivity of intraocular pressure. Yes, low-pressure (also known as normal-tension glaucoma) is hereditary; you are at a high risk of forming if any of your immediate family members have it.

Is Acute Angle Closure Glaucoma Hereditary

Family members of those with acute angle-closure glaucoma are ten times more likely to develop it. So experts believe that unknown genes must play some role.

Is Angle Closure Glaucoma Hereditary

Yes. There are about five genetic areas linked to the development of angle closure glaucoma.

Is Pigmentary Glaucoma Hereditary

Pigment glaucoma is also known as pigment dispersion syndrome when pigment rubs off the back of the eye’s iris. It is believed to be inherited.

What About Pets, Is Glaucoma a Hereditary Disease In Our Lovely Pets?

Glaucoma is an eye condition that can occur in dogs and cats, just like us.

Is Glaucoma a Hereditary Disease In Dogs or A Genetic Disease

Dogs also suffer from the same hereditary disease as humans, including glaucoma. This disease can similarly affect them as it affects us. In most cases, it is inherited, but it could be a genetic disease in some rare cases. It is most commonly seen in purebred dogs.

Is Glaucoma a Hereditary Disease In Cats or A Genetic Disease

Cats also may suffer from the same hereditary disease as humans, including glaucoma. This disease can similarly affect them as it affects us, but it is rare. Primary glaucoma in cats is rare but can be predisposed in Siamese and Burmese cats.

What Medications Can Help Treating Glaucoma

Various treatment options are available for treating glaucoma. However, there is no cure for glaucoma, and medications help reduce the symptoms and delay the progression of the disease. 

Glaucoma medications for humans

Medications for the treatment of glaucoma include

Eyedrops for glaucoma

 It is most likely that your treatment of glaucoma will begin with eye drops. The medications reduce the eye pressure by enhancing the fluid drains from your eye or reducing the amount of fluid your eye makes. Prescription eye drops medications include prostaglandins, beta-blockers, alpha-adrenergic agonists, rho-kinase inhibitors, cholinergic agents, and carbonic anhydrase inhibitors

Oral medications for glaucoma

Oral medications may be prescribed along with eye drops if eye drops do not work to reduce the eye pressure to the required levels. Usually, carbonic anhydrase inhibitors are orally prescribed.

Other therapies for glaucoma

Other treatment procedure includes laser therapy and different surgical procedures that aim to improve drainage of the eye, thus lowering the eye pressure

Glaucoma medications for dogs and cats

Various medications are available for reducing the pressure in the eye. These medications are also used in humans for glaucoma. The treatment involves regular and consistent application to the eye, just like humans. Various classes of drugs such as 

  • Osmotic agents (mannitol, glycerin, and isosorbide) are used in veterinary glaucoma patients
  • Carbonic anhydrase inhibitors are also used for treating glaucoma. Topical agents such as dorzolamide, brinzolamide, and a combination of dorzolamide and timolol. Oral agents such as acetazolamide and methazolamide are also available. 
  • Beta-blockers are also effective treatment medications in glaucoma. Timolol is the most widely used topical medication. Other beta-blockers such as Levobunolol, Carteolol, metipranolol, and betaxolol are also available. 
  • Prostaglandin analogs are the most effective drugs in treating glaucoma in animals. The most commonly used prostaglandin is latanoprost. 

In some cases, glaucoma can also be treated with surgery. 

So, Is Glaucoma Hereditary in Humans, Dogs and Cats?

Yes, glaucoma is hereditary in humans, dogs, and cats. However, hereditary is not very common in dogs and cats as in humans.
