Acute Angle-Closure Glaucoma
Acute Angle-Closure Glaucoma Treatment
Self-Care at Home
No self-care is effective. Immediate treatment by an ophthalmologist is necessary to try to prevent further permanent vision loss.
An ophthalmologist must treat angle-closure glaucoma with either laser therapy or surgical therapy (see Surgery).
- A laser iridotomy is the most commonly performed procedure. During a laser iridotomy, your eye doctor uses a laser beam to make a hole in the iris to reduce the pressure inside the eye. By making a hole in the iris, the fluid (aqueous humor) is better able to drain out from the posterior chamber to the anterior chamber of the eye.
- If the iris cannot be accessed with a laser beam for some reason, a surgical (or incisional) iridectomy is performed, wherein your eye doctor creates the hole in the iris by making surgical incisions.
Prior to a laser iridotomy, your ophthalmologist uses medicines to reduce the pressure inside the eye and to clear up the cloudiness of the cornea that occur during an acute attack of angle-closure glaucoma. Also, because the pupil is often partially dilated (or enlarged), it is constricted (or made smaller) before laser surgery. See Medications.
Medicines that are used for acute angle-closure glaucoma prepare you to undergo either a laser iridotomy or a surgical iridotomy. They come in the form of medicated eyedrops (see How to Instill Your Eyedrops).
Prior to surgery, your ophthalmologist uses medicines to reduce the pressure inside the eye and to clear up the cloudiness of the cornea that occur during an acute attack of angle-closure glaucoma.
In acute angle-closure glaucoma, several drugs are used simultaneously to accelerate and maximize their pressure-lowering effects. The drugs lower IOP by increasing the outflow of the fluid (aqueous humor) from the eye or by decreasing the production of fluid in the eye.
