Why do people get iridectomy?

Why do people get iridectomy?

In most patients, the iridotomy is placed in the upper portion of the iris, under the upper eyelid, where it cannot be seen. A small hole is placed in the iris to create a hole for fluid to drain from the back of the eye to the front of the eye. The purpose of an iridotomy is to preserve vision, not to improve it.

How is an iridotomy performed?

The treatment is to lower eye pressure using eye drops and potentially oral medications, but the definitive treatment at the time of the glaucoma attack is to perform a laser iridotomy. In this procedure, a tiny hole is placed in the iris to allow the iris to fall away from the drainage area inside the eye.

What is the purpose of a surgical iridectomy during trabeculectomy surgery?

Conclusions. Trabeculectomy performed without peripheral iridectomy appears to be as effective in lowering intraocular pressure as when performed with peripheral iridectomy, but it is a safer procedure, with a lower incidence of postoperative inflammation.

Who needs iridectomy?

3. Who is a candidate for laser iridotomy? It is recommended in eyes which have the angle closed for at least half the eye and have high eye pressure or glaucoma. In eyes which have a closed angle but normal eye pressure and no optic nerve damage, laser iridotomy may be recommended as a preventive treatment.

What is a peripheral iridectomy?

Peripheral iridectomy: A surgical procedure in which a hole is made in the periphery (outer part) of the iris by removing a full-thickness piece from the iris in order to treat a specific type of glaucoma called narrow-angle glaucoma (or angle-closure glaucoma).

Is laser iridotomy necessary?

Who is a candidate for laser iridotomy? It is recommended in eyes which have the angle closed for at least half the eye and have high eye pressure or glaucoma. In eyes which have a closed angle but normal eye pressure and no optic nerve damage, laser iridotomy may be recommended as a preventive treatment.

Does laser iridotomy reduce eye pressure?

Laser iridotomy treatment is used for preventing spikes in intraocular pressure (IOP) in cases of acute closed-angle glaucoma. Laser iridotomy helps relieve pressure within the eye by attempting to “open” a “narrow” angle.

How long does iridotomy surgery take?

The procedure usually takes 5-10 minutes and some patients may experience minor pain.

Is iridotomy painful?

The laser peripheral iridotomy is an almost painless procedure. The patient may feel a slight stinging in the eye after the procedure, or a slight foreign body sensation which will go away soon.

What causes narrow-angle glaucoma?

Angle-closure glaucoma, also known as narrow-angle glaucoma, is caused by blocked drainage canals in the eye, resulting in a sudden rise in intraocular pressure. This is a much more rare form of glaucoma, which develops very quickly and demands immediate medical attention.

What laser is used for Iridotomy?

Iridotomy can be accomplished using the photodisruptive Q-switched Nd:YAG laser (Nd:YAG) or the photo-thermal Nd:YAG-KTP 532 nm (which is still often called Argon laser) and solid-state lasers.

What is a hole in the iris?

Coloboma of the iris is a hole or defect of the iris of the eye. Most colobomas are present since birth (congenital). Coloboma of the iris can look like a second pupil or a black notch at the edge of the pupil. This gives the pupil an irregular shape.

What is the narrow angle of the eye?

Narrow Angles. “Narrow angle” refers to the shallow space between the cornea at the front of the eye and the coloured iris that lies just behind the cornea.

What is Pi eye surgery?

An important part of the Pi in Eye(Pie) surgery is the artificial biocompatible presbyopic artificial lens, which allows one to see far and near in each eye. These are known as Presbyopic implants or Pi. They are made by artificial means and not taken from cadavers.
