What Is Glaucoma?

The optic nerve provides visual info into your brain from your eyes.

Glaucoma is usually, but not always, the result of abnormally high pressure in your eye. Over time, the higher pressure can erode your optic nerve tissues, which may possibly lead to vision loss or even blindness. If it’s found early, you could well be able to prevent extra vision loss.

Which Are the Signs of Glaucoma?

The most common kind of glaucoma is primary open-angle glaucoma. It has no signs or symptoms anyhow gradual vision loss. Because of this, it’s vital that you go to yearly comprehensive eye exams, therefore, your ophthalmologist eye pro can track any changes in your vision.

Acute-angle terminal illness, which can be known as narrow-angle cataract, is a health emergency. See your doctor immediately in Case You experience the following symptoms:

  • intense eye discomfort
  • nausea
  • Vomiting
  • Redness in your eye
  • Unexpected vision disturbances
  • Watching colored rings around lights
  • Sudden blurred vision

What Causes Glaucoma?

The trunk of one’s eye always makes a clear fluid called aqueous humor. While this fluid is made, it fills the front part of your eye. Afterward, it leaves your eye through stations in your cornea and iris. If those stations are either blocked or partially obstructed, the pore pressure in mind, which is called the intraocular pressure (IOP), can grow. Since your IOP increases, your adrenal nerve may become damaged. As injury to your guts grows, you can begin losing sight in mind.

What causes the pressure on your eye to increase isn’t always understood.
Blocked or limited drainage from the mind

  • Medications, like corticosteroids
  • weak or decreased blood circulation into an optic nerve
  • elevated or high blood pressure

Which Are the Kinds of Glaucoma?

Open-Angle (Chronic) Glaucoma

Open-angle, or even chronic, glaucoma does not have any signs or symptoms except for gradual vision loss. This loss might be so slow that your vision can endure irreparable damage before any signs become apparent.

Angle-Closure (Acute) Glaucoma

When the stream of your humor fluid is unexpectedly blocked, the accelerated buildup of fluid might cause a severe, quick, and debilitating increase in pressure. Angle-closure glaucoma can be an emergency situation. You ought to call your doctor at once in the event you begin experiencing symptoms, such as acute pain, nausea, vomiting, and blurry vision.

Congenital Glaucoma

Children born with congenital cataract possess a flaw in the angle in this attention, which slows or prevents ordinary fluid drainage. Congenital glaucoma usually presents with symptoms, such as cloudy eyes, excessive tearing, or sensitivity to light.

Secondary Glaucoma

Secondary glaucoma is usually a side effect of injury or yet another eye condition, like disease or eye tumors. Medicines, like corticosteroids, can also bring about this kind of glaucoma. Rarely, eye operation can result in secondary pneumonia.

Normal Tension Glaucoma

In some instances, people without increased eye pressure develop damage to their optic nerve. The cause of this isn’t known. But, extreme sensitivity or even a lack of blood flow to your optic nerve might be an element in such glaucoma.

Who Is at Risk of Glaucoma?


People over 60 are at heightened risk of glaucoma, warns the NEI, and the risk of glaucoma increases marginally by each year old. If you’re African American, your growth at hazard begins at age 40.


African Americans or individuals of African descent are more prone to develop glaucoma than Caucasians. People of Asian descent are at a higher chance of angle-closure glaucoma, and people of Japanese descent have an increased chance of developing low-tension glaucoma.

Eye Issues

Consistent eye discomfort and lean corneas often lead to greater pressure in your mind. Physical trauma or injury to your eye, such as being hit in mind, also can cause your attention pressure to rise.

Family History

Many types of glaucoma may run in families. If your parent or grandparent had open-angle glaucoma, then you’re at an elevated chance of developing the issue.

Medical History

Individuals with diabetes and those who have high blood pressure and heart problems have a higher probability of developing glaucoma.

Use of Certain Medication

Applying corticosteroids for extended periods may increase your chance of developing secondary glaucoma.

How Is Glaucoma Diagnosed?

To diagnose glaucoma, your ophthalmologist may wish to do a comprehensive eye exam. They’ll look for signs of corrosion, including loss of nerve tissue. They may also use one or more of these tests and procedures:

Detailed Medical History

Your doctor will want to learn what symptoms you are undergoing and if you have any personal or family history of glaucoma. Additionally, they request a general health and fitness assessment to find out whether any health issues could be impacting your attention health, like diabetes or higher blood pressure.

Pachymetry Exam

People with thin corneas have an increased probability of developing glaucoma. A pachymetry evaluation may tell your doctor if your corneas are thinner than average.

Perimetry Exam

This evaluation also referred to as a visual field exam, can tell your doctor if glaucoma affects your vision by quantifying your peripheral, or side, vision along with your fundamental vision.

How Is Glaucoma Treated?

The goal of glaucoma treatment is to reduce IOP to stop any extra vision reduction. On average, your doctor begins treatment with prescription eyedrops. If these do not function or even more complex treatment is needed, your doctor may indicate a few of the following remedies:


Many medicines created to reduce IOP are available. These medicines are readily available in the form of eye drops or pills, but the drops tend to be more common. Your physician can prescribe a mix of them.


If a slow or blocked channel is inducing raised IOP, your doctor may suggest surgery to make a drainage pathway for liquid or ruin tissues that are liable for the greater fluid.
A remedy for angle-closure glaucoma differs. This kind of glaucoma can be a medical emergency and requires immediate treatment to decrease eye pressure as fast as you can. Medicines are often tried first, to undo the angle closure, but this may be ineffective. A laser procedure called laser peripheral iridotomy might also be performed. This action creates small holes in your iris to allow for increased fluid movement.

Will an Individual with Glaucoma Go Blind?

In case your raised IOP may be stopped along with the pressure returned to normal, vision loss may be slowed or even stopped. However, because there isn’t any cure for glaucoma, you’ll likely need treatment for the rest of your life to regulate your IOP. Regrettably, vision lost as a consequence of glaucoma cannot be restored.

Could Glaucoma Be Prevented?

Glaucoma can’t be prevented, but it’s still essential to catch it early and that means you may begin treatment that may help prevent it from becoming worse. The best method to grab any type of glaucoma early is to have an annual preventive eye care appointment. Create an appointment with an ophthalmologist. Simple tests performed throughout these routine eye evaluations could have the ability to find damage from glaucoma until it progress and begins causing vision loss.
