Understanding Acute Angle-Closure Glaucoma: Causes and Risk Factors

Acute angle-closure glaucoma is a serious eye condition that occurs when the angle between the iris and the cornea becomes blocked, preventing proper drainage of the aqueous humor (the fluid inside the eye). This results in a rapid increase in eye pressure, which can lead to damage to the optic nerve and permanent vision loss if not treated immediately.

Causes

The exact cause of acute angle-closure glaucoma is not fully understood, but it is believed to be related to the shape of the eye and the position of the iris. Some common causes include:

  • Iris bombe: A condition in which the iris is pushed forward into the angle, blocking the drainage channels. This can be caused by a number of factors, including genetics, injury, or certain medical conditions.

  • Narrow angles: Some people are born with narrow angles between the iris and the cornea, which can make them more susceptible to angle-closure glaucoma.

  • Pupil dilation: Certain medications, such as certain types of antidepressants and antihistamines, can cause the pupils to dilate, which can push the iris forward and block the drainage channels.

Risk Factors

Certain factors can increase your risk of developing acute angle-closure glaucoma, including:

  • Age: The risk of angle-closure glaucoma increases as you get older.

  • Gender: Women are more likely to develop acute angle-closure glaucoma than men.

  • Ethnicity: Certain ethnic groups, such as Asians, are at a higher risk of developing angle-closure glaucoma.

  • Family history: If someone in your family has had angle-closure glaucoma, you may be at a higher risk of developing the condition.

  • Medical conditions: Certain medical conditions, such as diabetes and hypertension, can increase your risk of developing angle-closure glaucoma.

It’s important to understand the causes and risk factors of acute angle-closure glaucoma, as it can help to identify those who may be at a higher risk of developing the condition. If you have any risk factors or are experiencing symptoms of angle-closure glaucoma, it’s important to seek prompt medical attention to prevent permanent vision loss.

Please note that this is a serious condition that requires prompt medical attention. If you suspect you or someone you know is experiencing symptoms of acute angle-closure glaucoma, please seek medical attention immediately.

Symptoms and Diagnosis of Acute Angle-Closure Glaucoma

Acute angle-closure glaucoma is a medical emergency that requires prompt treatment to prevent permanent vision loss. It is important to be able to recognize the symptoms of this condition so that you can seek medical attention as soon as possible.

Symptoms

Symptoms of acute angle-closure glaucoma may include:

  • Severe eye pain: This is often described as a “throbbing” or “pounding” sensation, and can be accompanied by headache and nausea.

  • Blurred vision: This can be caused by the increased eye pressure, and may be accompanied by halos around lights.

  • Nausea and vomiting: These symptoms can be caused by the severe eye pain.

  • Redness of the eye: This is caused by the increased blood flow to the eye.

  • Sudden vision loss: This can occur if the angle-closure is not treated promptly.

Symptoms of acute angle-closure glaucoma can come on suddenly and may be very severe. If you experience any of these symptoms, it is important to seek medical attention immediately.

Diagnosis

Acute angle-closure glaucoma is usually diagnosed by an eye doctor, such as an ophthalmologist or optometrist. The diagnosis is usually based on the symptoms, a physical examination of the eye, and the results of certain tests.

The following tests may be used to diagnose acute angle-closure glaucoma:

  • Tonometry: This test measures the pressure inside the eye. A high reading may indicate angle-closure glaucoma.

  • Slit-lamp examination: This test allows the doctor to examine the angle between the iris and the cornea to see if it is open or closed.

  • Ophthalmoscopy: This test allows the doctor to examine the optic nerve to see if it has been damaged by the increased eye pressure.

  • Gonioscopy: This test is used to examine the angle between the iris and the cornea.

It is important to seek medical attention immediately if you suspect you or someone you know is experiencing symptoms of acute angle-closure glaucoma, as it is a serious condition that requires prompt treatment to prevent permanent vision loss.

Please note that this is a serious condition that requires prompt medical attention. If you suspect you or someone you know is experiencing symptoms of acute angle-closure glaucoma, please seek medical attention immediately.

Treatment Options for Acute Angle-Closure Glaucoma

Acute angle-closure glaucoma is a serious eye condition that requires prompt treatment to prevent permanent vision loss. The goal of treatment is to lower the pressure inside the eye and prevent further damage to the optic nerve.

Medical Treatment

Medical treatment for acute angle-closure glaucoma typically involves the use of medications to lower the pressure inside the eye. Medications used to treat acute angle-closure glaucoma include:

  • Eye drops: These may include drugs such as pilocarpine, which causes the pupil to constrict, and beta blockers, which lower the production of aqueous humor.

  • Oral medications: These may include drugs such as acetazolamide, which also lowers the production of aqueous humor.

These medications are used to lower the pressure inside the eye and prevent further damage to the optic nerve. They are usually used in combination with other treatments to achieve the best results.

Laser Peripheral Iridotomy (LPI)

Laser peripheral iridotomy (LPI) is a surgical procedure that is used to treat acute angle-closure glaucoma. It involves making a small hole in the iris with a laser, which allows the aqueous humor to flow more freely and lower the pressure inside the eye. LPI is usually performed on an outpatient basis and is usually done under local anesthesia.

Filtering Surgery

Filtering surgery is a procedure to create a new drainage path for the aqueous humor to lower intraocular pressure. This surgery is usually a last resort and only done if other methods fail to control the intraocular pressure.

It is important to note that treatment for acute angle-closure glaucoma is not a one-time thing and patients will need to continue to monitor their eye pressure and may need to continue taking medications to maintain healthy eye pressure.

Please note that this is a serious condition that requires prompt medical attention. If you suspect you or someone you know is experiencing symptoms of acute angle-closure glaucoma, please seek medical attention immediately and follow the treatment plan suggested by the doctor.

Prevention and Management of Acute Angle-Closure Glaucoma

Acute angle-closure glaucoma is a serious eye condition that requires prompt treatment to prevent permanent vision loss. While it is not always possible to prevent the condition, there are steps you can take to reduce your risk and manage the condition once it has developed.

Reduce Your Risk

There are several steps you can take to reduce your risk of developing acute angle-closure glaucoma, including:

  • Regular eye exams: Regular eye exams can help detect the early signs of angle-closure glaucoma, which can then be treated to prevent further damage.

  • Avoiding certain medications: Certain medications, such as certain types of antidepressants and antihistamines, can cause the pupils to dilate, which can increase the risk of angle-closure glaucoma.

  • Managing underlying medical conditions: Medical conditions such as diabetes and hypertension can increase the risk of angle-closure glaucoma, so it’s important to manage these conditions and keep them under control.

  • Wearing sunglasses: Wearing sunglasses can help protect your eyes from the sun’s harmful UV rays, which can damage the eyes over time.
