Preventing Acute Angle Closure Glaucoma: A Comprehensive Guide 

Gina Walters


Acute Angle Closure Glaucoma

Acute Angle Closure Glaucoma (AACG) is a serious eye condition that must be detected early and treated immediately.

A sudden narrowing or shutting of the drainage angle in the eye causes this vision-threatening condition.

It leads to an abrupt increase in the Intraocular Pressure.

If this medical condition is left untreated, it may cause severe eye pain, blurred vision, and even permanent vision loss.

In this article, we’ll focus on the symptoms, causes, and treatments of Acute Angle Closure Glaucoma.

Understanding Acute Angle Closure Glaucoma

Acute Angle Closure Glaucoma (AACG) is a disorder that causes high eye pressure abruptly.

This occurs when the eye’s drainage angle gets unexpectedly closed, hindering fluid drainage.

Irreversible vision loss may result if AACG is not treated immediately.

In AACG and Narrow-Angle Glaucoma, increased Intraocular Pressure (IOP) occurs because the eye’s drainage angle is blocked.

AACG can be uncomfortable and must be treated by a doctor regularly.

    Significant eye irritation, blurred vision, headaches, nausea, and a red-eye look are among the severe symptoms of AACG.

    The pupils may enlarge and stop responding to light, and the eyesight may quickly deteriorate.

    Some of the symptoms of AACG are: 

    Patients with blurred or poor eyesight might notice halo effects around lights.

    It’s important to identify these signs as soon as possible to seek medical attention.

    Did you know?
    Glaucoma often progresses without noticeable symptoms in the early stages. Regular eye exams, especially if you’re at risk, are crucial for early detection.

    Acute Angle Closure Glaucoma Causes

    Your eye’s drainage system consists of a network of canals. 

    Between your iris and cornea is a tissue mesh where these canals reside. AACG entirely blocks these canals. 

    It prevents fluid from passing through them. Your optic nerve may become damaged due to the mounting pressure.

    Some other causes of AACG are: 

    • Age: Older persons have an increased risk of AACG
    • Pupil dilation: Eye tests and other procedures that expand the pupils may trigger an episode in those who are at risk
    • Family history: A person may be more susceptible if they have Glaucoma in the family

    An awareness of these factors is essential for early identification and successful treatment.

    If diagnosed with Acute Angle Closure Glaucoma, consistent monitoring and adherence to prescribed treatment plans are essential to prevent vision deterioration.

    Your doctor will attempt to relieve some of the pressure in your eye as the initial step in treating your acute angle closure attack. 

    They could use:

    • Drops that make your pupil smaller
    • Medication that reduces the amount of fluid produced by your eyes

    Medication, laser surgery, or conventional surgery are all possible forms of treatment for AACG.

    Some of the available treatments for AACG are: 

    • Glaucoma medications: Injectable and topical medications are applied to help lower eye pressure (Low IOP)
    • Surgery: Surgery may occasionally be necessary to address the anatomical issues causing angle closure
    • Laser Peripheral Iridotomy (LPI): Some individuals may also choose for laser operation by drilling a tiny hole in the iris’ border for proper fluid drainage

    It is important to seek immediate medical help if diagnosed with AACG to avoid potential risks and side effects.

    Summing up

    Acute Angle Closure Glaucoma is a serious medical condition that requires immediate medical assistance. 

    Early medical attention can mean the difference between maintaining and completely losing your vision.

    Significant eye discomfort, headache, and visual blurring are some of the symptoms of AACG. 

    Medications, Laser Peripheral Iridotomy (LPI), and surgery may help in treating Acute Angle Closure Glaucoma. 

    AACG can be avoided with early detection and prompt treatment.

    It is important to emphasize the importance of eye health and regular exams.

    Frequently Asked Questions

    How serious is Acute Angle Closure Glaucoma?

    Acute Angle Closure Glaucoma is a highly serious condition. 

    If not treated, it might lead to vision loss and even blindness due to a sudden rise in eye pressure, necessitating immediate medical attention and intervention.

    What is the best treatment for Acute Angle Closure Glaucoma?

    The primary treatment for Acute Angle Closure Glaucoma is immediate medical intervention to lower eye pressure. 

    This often involves medications, laser therapy (Iridotomy), or surgery (Iridectomy or Trabeculectomy) to prevent further damage and preserve vision.

    How is Acute Angle Closure Glaucoma diagnosed?

    Acute Angle Closure Glaucoma is diagnosed through a comprehensive eye exam. 

    This includes measuring Intraocular Pressure, assessing the anterior chamber angle, evaluating the optic nerve, and considering symptoms.

    Accurate diagnosis is crucial for the immediate treatment of ACAG.

    Where can I find more information about managing Acute Angle Closure Glaucoma?

    For information about Acute Angle Closure Glaucoma, treatment choices, and support for those affected by this ailment, consult credible sources and resources.
