Laser Iridotomy Explained: Treatment for Narrow Angles

Narrow angles in the eye can put patients at risk for a dangerous type of glaucoma known as angle-closure glaucoma. While many people are familiar with open-angle glaucoma, narrow-angle or angle-closure forms can develop quickly and cause sudden vision loss if not treated. At Tres Vision Group in Melbourne, our eye care team offers advanced diagnostic imaging and laser iridotomy, a minimally invasive procedure that helps prevent angle-closure and protect your long-term vision.

What Are Narrow Angles?

The eye drains fluid (aqueous humor) through a structure called the drainage angle, located between the iris and cornea. In some people, this angle is naturally narrow, leaving less space for fluid to exit the eye. This can lead to pressure buildup and a potential sudden blockage. This obstruction can cause an acute angle-closure glaucoma attack — a medical emergency requiring immediate care.

Narrow angles are discoverable during routine eye exams, especially in people over 40 or those with a family history of glaucoma. Fortunately, when caught early, narrow angles can be treated effectively before symptoms ever appear.

What Is Laser Iridotomy?

Laser peripheral iridotomy is a preventive treatment for narrow angles. It involves using a highly focused laser to create a tiny opening in the outer edge of the iris. This allows fluid to flow more freely through the eye, relieving pressure and opening the drainage angle.

The procedure is performed in-office and usually takes just a few minutes per eye. Numbing drops are used for comfort, and most patients experience only mild sensitivity afterward.

Who Needs This Procedure?

Laser iridotomy is recommended for patients who have been diagnosed with:

• Narrow or “occludable” angles
• A history of angle-closure symptoms (halos, pain, blurred vision)
• Treatment of the second eye following an acute angle-closure event in the first eye
• High risk of angle-closure based on imaging and exam findings

Our eye doctors at Tres Vision Group use precise imaging tools to assess each patient’s angle anatomy and determine whether iridotomy is the best option.
