Does Diabetes Cause Glaucoma? Myths, Facts, and Hidden Risks Explained

What Is Glaucoma?

Basically, glaucoma is an eye disease that damages the optic nerve responsible for transmission of visual information directly via eyes toward brain.

Most commonly, the problem arises when the fluid starts building up inside the eyes, thereby putting more pressure in the eye. Gradually, this increased pressure results in damaging the optic nerve fibers and a loss of sight.

Usually, the earliest sign is losing the sight of objects that are out of focus also known as peripheral vision. If neglected, it can lead to complete loss of sight through progressive loss of peripheral vision.

Since glaucoma progresses gradually and without any noticeable symptoms until it’s quite late, it is one of the major reasons why lot of people get permanent vision damage from it.

Does Diabetes Cause Glaucoma?

Not really, having diabetes doesn’t mean that you can get glaucoma. On the other hand, patients with diabetes are at a higher risk of glaucoma than non-diabetic people.

Among the factors that links these two diseases are changes in blood vessels, circulation, and eye structures, which raise the risk of optic nerve damage.

Instead of being a direct cause, diabetes might alter the body’s internal environment in a way that highly increases the risk of developing or progressing of the glaucoma.

How Does Diabetes Increase the Risk of Glaucoma?

There are multiple biological transformations linked to diabetes may lead to the onset of glaucoma.

1- It Damages the Small Blood Vessels

Diabetes causes changes in the smallest blood vessels of the body, along with the one that nourishes the optic nerve with oxygen and nutrients.

In cases where blood circulation is disrupted, the optic nerve could get highly susceptible to pressure-induced injuries, even if the eye pressure is within the normal limits.

Due to this vascular strain the risk of damage to the optic nerves improves quite a lot in the long run.

2- It increases the risk of Neovascular Glaucoma

Neovascular glaucoma is the most serious and dangerous glaucoma-related complication that can result from diabetes.

As the diabetic retinopathy progresses, the retina can get severely oxygen-deprived. This initiates the development of abnormal new blood vessels in the body.

These newly formed, weak blood vessels are highly likely to invade the eye’s drainage system, thereby blocking fluid outflow and causing a sharp, dangerous rise in eye pressure.

If not taken care of immediately, a dramatic loss of vision could occur.

3- Blood Sugar Fluctuations Impact Eye Physiology 

Frequent ups and downs in blood sugar levels can lead to changes in the lens such as altering of shape and thickness.

In some people, these alterations can lead to changes in fluid flow pathways within the eye and to the development of a higher risk for pressure-related problems.

Diabetes and Glaucoma: Myths vs Facts

Misinformation is a major reason why patients avoid getting their eyes checked on time. Knowing the correct information will help you reduce those risks.

Myth 1: If my diabetes is well controlled, I cannot get glaucoma

Fact: Maintaining good control of your blood sugar will certainly minimize the diabetic complications that one can experience, however, will not completely prevent you from getting glaucoma. Genetically inherited traits, age, and the changes in the vascular system can also be factors of the disease.

Myth 2: I Will Feel The Pressure In My Eyes Increasing

Fact: The majority of the population is unable to detect when their eye pressure is increasing. Normally, the symptoms of glaucoma would not be present even if the disease progresses.

Therefore, one must get one’s eyes checked on a regular basis.

Myth 3: Glaucoma only happens to the elderly

Fact: Although age is a significant risk factor, glaucoma may strike anyone irrespective of their age. Diabetes may alter the time frame at which the person becomes susceptible to the disease.

Myth 4: It is possible to recover from glaucoma-induced blindness

Fact: Once vision is lost because of glaucoma, it can never be restored. The main aim of the treatment is to stop the damage and maintain the current status of vision.

What Are the Warning Signs of Glaucoma?

Most of the people who have glaucoma won’t observe any symptoms at the beginning. Nevertheless, if the condition starts worsening, there are a few symptoms that patients could experience:

• Loss of side (peripheral) vision
• Tunnel vision
• Blurred vision
• Halos around lights
• Eye redness
• Severe eye pain
• Headaches
• Nausea associated with eye pain

An abrupt change in our vision is a serious medical issue and needs an urgent evaluation.

Final Thoughts

Diabetes does not directly cause glaucoma, But it increases the likelihood of causing damage to the optic nerve resulting in loss of vision.

However, if the problem is caught early, the diabetes can be properly controlled, and if the eyes are regularly checked, the chances of complications can be reduced greatly.

At Sarvesh Health City, a patient can get help from the highly advanced diagnostic tools and techniques used for diabetic eye disease screening and glaucoma evaluation. The eye specialist here observes the condition of a patient and creates the most suitable personalized treatment plan. This multidisciplinary approach not only detects the onset of complications but also provides maximum support for maintaining eye health.

Those who want to visit the best eye hospital in Hisar should know that with timely screening and expert management, one can preserve their vision while reducing the risk of blindness to great extent.
