Acute Angle-Closure Glaucoma: Everything You Need to Know

Acute Angle-Closure Glaucoma: Everything You Need to Know

Within the realm of glaucoma, numerous classification methods abound, yet a prevailing consensus reveals four fundamental categories that delineate this ocular affliction.

First, we have Primary Open Angle Glaucoma, where the fluid drainage channels of the eye become less efficient over time, elevating intraocular pressure. Second, Angle Closure Glaucoma emerges when the angle between the iris and cornea narrows, impeding fluid outflow. Normal Tension Glaucoma, on the other hand, emerges as the paradoxical variant, manifesting in optic nerve damage despite normal intraocular pressure levels.

Finally, Secondary Glaucoma is a consequence of other ocular conditions or external factors influencing the eye’s drainage system.

For today, we aim to focus on Acute Angle-Closure Glaucoma, as you’ve probably already guessed. Keep reading to find out the basics!

How can we define Acute Angle-Closure Glaucoma?

Acute angle-closure glaucoma is a relatively rare but serious and urgent condition. It disrupts the flow of aqueous humor, the vital liquid that sustains the shape and function of the eye. This blockage between the anterior and posterior chambers of the eye causes the iris to bow, narrowing the angle within the anterior chamber. Without swift intervention, it can lead to permanent loss of vision or even blindness.

Recognizing the urgency, timely treatment is crucial to mitigate the risk of irreversible visual impairment. A clear understanding of this condition empowers us to address it with the prompt and proper care it demands.

What are the causes of Acute Angle-Closure Glaucoma?

Acute angle-closure glaucoma can be triggered by various factors, placing specific individuals at higher risk. Those who have smaller eyes are more susceptible due to narrower drainage canals, increasing the likelihood of blockages.

Other risk factors encompass far-sightedness, advancing age, and having a family history of the condition. Additionally, specific drugs, such as duloxetine, sumatriptan, and topiramate, have been associated with a heightened risk.

Before commencing any new medication, it is important for individuals at risk to consult a healthcare professional. Vigilance and medical guidance are the keys to managing this potentially serious condition.


Acute angle-closure glaucoma’s symptoms strike suddenly and demand attention as soon as possible. You need to look out for blurred vision, intense pain in one eye, persistent headache, and feelings of nausea leading to vomiting. Moreover, some may witness rainbow-colored rings encircling bright lights.

If any of the aforementioned signs manifest, you definitely shouldn’t delay seeking medical help. Timely intervention is vital to prevent severe complications and safeguard your vision. Therefore, you need to remember that swift action is the key to tackling acute angle-closure glaucoma and preserving your precious sight.


When dealing with acute angle-closure glaucoma, doctors focus on two primary objectives: lowering the elevated pressure inside the eye and alleviating the distressing symptoms.

To achieve this, medical professionals may administer medications such as glycerol, acetazolamide, or pilocarpine, which effectively reduce the pressure within the eye. Additionally, topical glaucoma drugs such as beta-blockers or alpha agonists might be prescribed for the same purpose.

Laser treatment is another valuable option to restore the flow of aqueous humor and address acute angle-closure glaucoma effectively.
For anyone affected by the condition, it is crucial to seek advice from a healthcare professional promptly, as immediate treatment is crucial to prevent any potential long-term damage to vision.
