Signs of Glaucoma and How It's Treated

Glaucoma is a group of eye conditions that damage the optic nerve, which is essential for good vision.This damage is often caused by an abnormally high pressure in your eye.Glaucoma is one of the leading causes of blindness for people over the age of 60.However, with early detection and treatment, you can often protect your eyes against serious vision loss.This article will explore the signs of glaucoma and how it is treated.

Signs of Glaucoma

1.Gradual Loss of Peripheral Vision:

One of the most common signs of open-angle glaucoma, the most prevalent type, is the gradual loss of peripheral vision.This change is so slow that you may not notice it until significant vision has been lost.

2.Tunnel Vision:

In the advanced stages of the disease, people with glaucoma may experience tunnel vision, where the central vision remains but peripheral vision is lost.

3.Severe Eye Pain:

Acute angle-closure glaucoma, a less common form, can cause sudden and severe eye pain.This condition is a medical emergency and requires immediate attention.

4.Blurred Vision:

Experiencing blurry or hazy vision can be a sign of glaucoma.It often occurs alongside halos around lights.

5.Halos Around Lights:

Seeing rainbow-colored circles or halos around lights, especially at night, can be indicative of glaucoma.

6.Redness in the Eye:

Redness in the eye can be a sign of glaucoma, particularly if it occurs with other symptoms like pain or vision changes.

7.Nausea and Vomiting:

These symptoms can accompany acute angle-closure glaucoma and should not be ignored.


Frequent headaches, especially when paired with visual disturbances, can be a sign of glaucoma.

Diagnosing Glaucoma

Regular eye exams are crucial for early detection of glaucoma.During an eye exam, your eye doctor will check for the following:

Eye Pressure:

Measuring the intraocular pressure (tonometry) can help detect glaucoma.

Optic Nerve Damage:

Examining the optic nerve for damage using imaging technology.

Vision Loss:

Testing your peripheral vision (visual field test) to check for blind spots.

Corneal Thickness:

Measuring the thickness of your cornea (pachymetry) can provide information about your risk for developing glaucoma.

Drainage Angle:

Inspecting the angle in your eye where the iris meets the cornea (gonioscopy).

Treatment of Glaucoma

While glaucoma damage cannot be reversed, treatment can help slow or prevent vision loss, especially when detected early.Treatment options include:


Prescription eye drops are the most common early treatment for glaucoma.They work by either reducing the production of fluid in your eye or increasing the outflow of fluid from your eye.

2.Oral Medications:

If eye drops alone don't bring the pressure down to the desired level, your doctor may prescribe oral medications.

3.Laser Treatment:

Laser therapy can help fluid drain out of the eye, reducing intraocular pressure.Common laser treatments include trabeculoplasty, iridotomy, and cyclophotocoagulation.


When medications and laser treatments are not effective, surgical options may be considered:

Trabeculectomy: Creating a new drainage pathway for the fluid.

Drainage Implants: Inserting a small tube to help drain fluid.

Minimally Invasive Glaucoma Surgery (MIGS): Procedures that involve less postoperative discomfort and shorter recovery times.

5.Lifestyle and Home Remedies:

Healthy Diet: A diet rich in fruits and vegetables may help support eye health.

Regular Exercise: Moderate exercise may help reduce eye pressure.

Avoiding Excessive Caffeine: Large amounts of caffeine can increase eye pressure.

Elevating Your Head While Sleeping: Sleeping with your head elevated by about 20 degrees may help reduce eye pressure.


Early detection and treatment of glaucoma are crucial in preventing significant vision loss.Regular eye exams, especially if you are at a higher risk, can lead to early diagnosis and more effective management of the disease.If you notice any symptoms of glaucoma, seek medical advice promptly to protect your vision.
