GlaucomaGlaucoma is an eye condition that can damage the optic nerve in the eye. The optic nerve is responsible for capturing the visual details and sharing them with your brain. Glaucoma happens when there is increased pressure inside your eye (increased intraocular pressure) which damages the optic nerve. If left untreated, this may lead to loss of vision or blindness. However, with prompt diagnosis and treatment, you may be able to prevent vision loss and slow the progression of disease.
Glaucoma can be classified into various types. The two most common types of glaucoma are:
This article will discuss narrow-angle glaucoma, its symptoms, and treatment options. Also, you will find out what happens when it is not treated.
Let’s get started!
Angle-closure glaucoma is also known as narrow-angle glaucoma, caused by blockage of drainage canals in the eye. Blockage results in a sudden rise in eye pressure (intraocular pressure). Narrow-angle closure glaucoma is rare. It can develop quickly and requires immediate medical treatment.
An acute episode of narrow-angle glaucoma is considered a medical emergency. If the pressure in the eye is not decreased quickly, there is a possibility that you may have permanent vision loss. If you have severe pain in one eye, headache, halos around lights, or blurry vision that comes on suddenly, go to the nearest emergency department.
Narrow-angle closure glaucoma is referred to as a sneaky thief of sight. Often, people affected by the disease do not experience any warning symptoms. The pressure in the eye increases drastically and within a short period. When an acute episode occurs, symptoms include:
If you experience any of these symptoms, you should immediately go to the nearest emergency room.
Eye surgery (a procedure called laser peripheral iridotomy) can be done to keep the drainage in the eye unblocked on a permanent basis. For some people, this surgery keeps intraocular pressure at a healthy level and no other treatment is required. For others, eye pressure may still be elevated after surgery which requires ongoing medications for treatment.
Acute angle closure glaucoma is a serious medical emergency. If the intraocular pressure is not decreased by treatment, it may cause blindness. Hence, if you experience any symptoms related to acute angle closure glaucoma, immediately seek medical attention.
If you experience symptoms of narrow-angle glaucoma, visit an eye doctor or emergency room immediately. Treatment must begin as soon as possible to minimize risk of permanent blindness. Once a diagnosis of narrow-angle glaucoma is confirmed, the first step of treatment is applying eye drops to reduce the pressure in your eyes.
After the eye pressure is reduced, your doctor may perform a procedure: laser iridotomy. In this procedure, laser light is used to create a small hole in the iris (the coloured part of your eye). This allows fluid in your eye to drain easily to prevent future episodes of narrow-angle glaucoma.
Your eye doctor may recommend medications that:
Medications may be eye drops, pills, or IV medicines.
Various medications include:
Glaucoma is typically a slow progressive disease. However, in the case of narrow-angle closure glaucoma, eye pressure rapidly increases due to a complete blockage of drainage. Symptoms like severe eye pain, headache, halos, and blurry vision flare up suddenly. Angle-closure glaucoma is a medical emergency and you should get medical attention as quickly as possible. If not treated, this glaucoma may cause blindness in the affected eye within 3-5 days.
