Angle-Closure Glaucoma

The incidence of angle-closure glaucoma varies depending on the population and geographic location. In general, it is less common than open-angle glaucoma, which is the most common type of glaucoma. 

In the United States, it is estimated that angle-closure glaucoma accounts for about 10% of all cases of glaucoma. The incidence of angle-closure glaucoma is higher in certain ethnic groups such as Asians and Eskimos. In these populations, the incidence can be as high as 50% of all cases of glaucoma. 

Worldwide, the incidence of angle-closure glaucoma is higher in certain regions such as Asia and the Middle East. It is estimated that up to 90% of glaucoma cases in some Asian countries are due to angle-closure glaucoma. 

It’s important to note that angle-closure glaucoma can be a medical emergency and requires immediate treatment to prevent irreversible vision loss. If you are experiencing sudden eye pain, redness, blurred vision, or halos around lights, seek medical attention immediately. 

Angle closure glaucoma, also known as acute angle closure glaucoma, is a type of glaucoma that occurs when the fluid pressure inside the eye (intraocular pressure) rises rapidly due to a sudden blockage of the drainage system of the eye. This blockage occurs when the angle between the iris (the colored part of the eye) and the cornea (the clear outer layer of the eye) becomes too narrow or completely closes, preventing the fluid from draining properly. 

This condition is considered an emergency and requires immediate medical attention as it can cause permanent damage to the optic nerve and lead to vision loss if not treated promptly. Symptoms may include sudden eye pain, blurred vision, seeing halos around lights, nausea, and vomiting. 

Treatment usually involves reducing the intraocular pressure using eye drops, oral medications, or in severe cases, surgery. Laser iridotomy, a procedure that creates a small hole in the iris to relieve the blockage and allow the fluid to drain, is often the first line of treatment for angle closure glaucoma. 

There is no specific “angle closure glaucoma kit” available. However, people who are at risk of developing angle closure glaucoma or have been diagnosed with the condition may benefit from having certain items on hand. These may include: 

  1. Prescribed medications: Depending on the severity of the condition, medications such as eye drops or pills may be prescribed by a doctor. It’s important to have these medications on hand and use them as directed. 
  2. Contact information: In case of an emergency or worsening symptoms, it’s important to have the contact information for your ophthalmologist or optometrist readily available. 
  3. Sunglasses: Bright light or glare can worsen the symptoms of angle closure glaucoma. Wearing sunglasses can help reduce discomfort. 
  4. Emergency kit: It’s important to have a first aid kit on hand in case of an emergency. This may include items such as a flashlight, blanket, water, and non-perishable food. 
  5. Information on trigger factors: Certain factors can trigger an angle closure glaucoma attack, such as certain medications, emotional stress, and physical exertion. Having information on these triggers can help you avoid them and prevent attacks.
