Acute Angle-Closure Glaucoma Medical Treatment

There is no curative medical treatment for acute angle-postponement glaucoma. An ophthalmologist must treat angle-interruption glaucoma later either laser therapy or incisional surgical therapy (see Acute Angle-Closure Glaucoma Surgical Treatment). The use of eyedrops, oral medications (osmotic agents such as glycerol or carbonic anhydrase inhibitors such as Diamox [acetazolamide]), or intravenous medication (mannitol, an osmotic drug) are temporizing proceedings designed to bring the pressure in addition to to prior to surgical therapy.

Medicines that are used for acute angle-recess glaucoma prepare one to undergo either a laser iridotomy or a surgical iridotomy. They arrive in the form of medicated eyedrops (heavens How to Instill Your Eyedrops).

Prior to surgery, the ophthalmologist prescribes medicines to reduce the pressure inside the eye and to complimentary going on the cloudiness of the cornea that occurs during an acute violent behavior of angle-deferment glaucoma.

In acute angle-closure glaucoma, several drugs are used simultaneously to accelerate and maximize their pressure-lowering effects. The drugs degrade IOP by increasing the outflow of the unstructured (aqueous humor) from the eye or by decreasing the production of shapeless in the eye.

Acute Angle-Closure Glaucoma Surgical Treatment

Laser iridotomy

A laser iridotomy is the most commonly performed procedure. During a laser iridotomy, the ophthalmologist uses a laser beam to make a hole in the iris to nearly-establish plenty drainage and condense the pressure inside the eye. By making a hole in the iris, the formless (aqueous humor) is bigger able to drain out from the posterior chamber to the anterior chamber of the eye. Prior to a laser iridotomy, the ophthalmologist prescribes medicines to abbreviate the pressure inside the eye and to forgive going on the cloudiness of the cornea that occurs during an acute forcefulness of angle-postponement glaucoma. Also, because the pupil is often partially dilated (or enlarged), it is constricted (or made smaller) in the back laser surgery. See Acute Angle-Closure Glaucoma Medical Treatment.

Laser iridotomy is the treatment of substitute for angle-break glaucoma. Iridotomy is performed using either an argon laser or an Nd:YAG laser.

The laser beam creates an commencement in the iris through which the formless (aqueous humor), which is trapped in the posterior chamber, can achieve the anterior chamber and the trabecular meshwork (or drainage channels). As the vague flows into the anterior chamber through this launch in the iris, the pressure astern the iris (inside the eye) falls, allowing the iris to reward to its satisfying approach. This procedure opens the angle of the anterior chamber and relieves the blockage at the trabecular meshwork.

If the cornea is definitely cloudy or if the person cannot cooperate, or if the iris cannot be accessed taking into account a laser beam for some footnote, a surgical (or incisional) iridectomy is performed, in which the eye doctor creates the hole in the iris through a surgical incision.

Laser gonioplasty

Laser gonioplasty is sometimes used together later iridotomy as a treatment for angle-break glaucoma or as a performing accomplish to entre the angle until a laser iridotomy can be performed.

During a laser gonioplasty, a laser beam is used to make complex burns in the iris. These burns cause the iris to arrangement, pulling the iris out of the angle and commencement the angle, causing the pressure to fade away.

Other aqueous drainage surgery

In situations in which the ferociousness of acute angle-break glaucoma has existed without treatment for a longer period of time or there have been repeated attacks of acute angle-recess glaucoma, adhesions and scarring may be bureau a role moreover the peripheral cornea and the iris (peripheral anterior synechiae or PAS), continuously closing the angle. This is called chronic angle-break glaucoma. This type of glaucoma is not curable later iridotomy or iridectomy. In such cases, the ophthalmologist will surgically make a subsidiary drainage system for the vague in the anterior chamber, either through a trabeculectomy or using an aqueous shunt device.
