How is chronic angle-closure glaucoma treated?
The condition can often be treated permanently with lasers. The standard treatment for this type of glaucoma is called an iridectomy, which makes a hole to let fluid drain from the eye. It's important to get your eyes checked regularly, as some people may develop a case of chronic angle-closure glaucoma later in life, even after laser treatment.

Can you go blind with closed-angle glaucoma?
The damage causes your vision to slowly get worse. There are several types of glaucoma, with open-angle glaucoma and acute angle-closure glaucoma being the most common. Every form of glaucoma causes reduced vision and can cause blindness without treatment.
Which type of glaucoma is the most serious?
Certain drugs and eye diseases can cause yet another form of the disease, called secondary glaucoma. But probably the most serious form of the disease is closed-angle glaucoma. It occurs when the angle becomes suddenly blocked, causing pressure in the eye to rise sharply.
Do all glaucoma patients eventually go blind?
Glaucoma is a serious, lifelong eye disease that can lead to vision loss if not controlled. But for most people, glaucoma does not have to lead to blindness. That is because glaucoma is controllable with modern treatment, and there are many choices to help keep glaucoma from further damaging your eyes.

Sleeping with your head elevated may reduce your eye pressure at night and decrease your risk of glaucoma-related vision problems. Baseline eye pressure was measured prior to sleep, then at two-hour intervals during a sleep period lasting six hours.
Is angle-closure glaucoma sudden?
Angle-closure glaucoma This form of glaucoma occurs when the iris bulges. The bulging iris partially or completely blocks the drainage angle. As a result, fluid can't circulate through the eye and pressure increases. Angle-closure glaucoma may occur suddenly or gradually.
What is the number one treatment for glaucoma?
The most common treatment for glaucoma is prescription eye drops. They work by lowering the pressure in your eye and preventing damage to your optic nerve. These eye drops won't cure glaucoma or reverse vision loss, but they can keep glaucoma from getting worse.

Can angle closure glaucoma cause eye dilation?
If you don’t treat the problem quickly enough, you could lose your sight completely. You might have an attack of angle closure glaucoma if you have narrow drainage systems and your eyes dilate (your pupil gets bigger) too much or too quickly.
How is acute angle-closure glaucoma diagnosed?
The diagnosis is made from the symptoms and the appearance of your eye. A likely diagnosis may be made by your GP, by an emergency doctor or by an optician. The diagnosis is confirmed by an examination done by an eye specialist (an ophthalmologist). This usually involves examining your eye using a special light and magnifier called a slit lamp and measuring the pressure in your eye. A specialist can also use a gonioscope to directly examine the outflow channels around the trabecular meshwork area of your eye.
What is acute angle-closure glaucoma?
Acute angle-closure glaucoma occurs when the flow of aqueous humour out of the eye is blocked and pressure inside the eye becomes too high very quickly. It is an emergency because if it is not treated quickly, it can lead to permanent loss of vision. Acute angle-closure glaucoma is also sometimes referred to as acute closed-angle glaucoma or just acute glaucoma. For ease, this leaflet will use the term 'acute glaucoma'.
Is angle closure glaucoma an emergency?

What to put in glaucoma emergency kit?
Put together an acute angle-closure glaucoma emergency kit containing all the medication ( see panel),2needles and syringes that may be needed. Include a copy of the treatment protocol and the contact details of the nearest ophthalmologist. This will ensure that you and your team are prepared. Check expiry dates regularly as this sight-threatening emergency is uncommon. The storage container should be clearly labelled and kept in the emergency room for easy access. Every team member must know where the kit is stored and be familiar with its contents.

Common risk factors include hyperopia, female gender, use of antihistamines and cold medications and advanced age.
Why is my primary angle closed?
Primary angle closure is usually caused by an anatomic problem: e.g., an occludable angle due to high iris insertion, a shallow anterior chamber in a hyperopic eye, a plateau iris that is being pushed forward by an anteriorly rotated ciliary body or lens rise from a growing cataract.
What is the best treatment for pupillary block?
Definitive treatment of pupillary block is laser peripheral iridotomy (LPI). If procedural intervention isn’t possible (due to location of patient or poor view of the iris due to corneal edema), medical treatment is a good temporizing measure. Timolol, brimonidine, dorzolamide and their pharmacological similar cousins are common drop treatments. Timolol is fastest with onset of action in about 20 minutes. Prostaglandin analogs act too slowly to be acutely useful.
How to get rid of a swollen eye?
Apply proparacaine and a drop of betadine to the eye. Consider using a lid speculum. Using a 30-gauge needle on a plungerless syringe, enter the anterior chamber parallel to the iris plane. It usually only takes a few seconds to tap sufficiently. Use a drop of antibiotic before and after the procedure.
What happens when fluid stops flowing through the canals in the eye?
Acute angle closure happens when fluid stops flowing through the canals in the eye, creating pressure that can damage the optic nerve.
What laser do you use for LPI?
Laser settings vary greatly amongst physicians. We usually use a YAG laser with 4.0-5.0 mJ energy. Patients are often pre-treated with pilocarpine to constrict the pupil; note pilocarpine can move the lens forward and therefore exacerbate some types of angle closure, but will make the LPI easier. A Blumenthal or Abraham Iridotomy lens is recommended for stabilization and visualization. Target the iris crypts and look for refluxed pigment. Transillumination helps confirm patency. Avoid placing the LPI in clock hours with intermittent lid exposure or those near the tear lake.
What is closed angle glaucoma?
Closed-angle glaucoma is a condition in which the pressure inside of your eye becomes too high. There are a number of diseases that fall under the heading “glaucoma.”. Open-angle glaucoma is the most common form of the condition and it accounts for around 90 percent of all cases of glaucoma. Closed-angle glaucoma is much less common.
Why does pressure build up in closed angle glaucoma?
If you have closed-angle glaucoma, pressure builds because fluid isn’t flowing out of your eye as it should. Fluid is produced in the rear chamber of your eye, behind the iris. This fluid normally flows through your pupil into the front chamber of the eyeball. The fluid then goes through a series of channels called the trabecular meshwork ...
