The human eye is a complex organ comprising various components, including the iris, lens, and cornea. The iris (the colored part of the eye) controls the amount of light entering the pupil. However, in some individuals, the angle between the iris and cornea becomes too narrow, leading to a condition known as narrow angles. If left untreated, this condition can result in increased intraocular pressure (IOP) and potential vision loss.
In this article, we’ll explore narrow angles in detail and discuss how laser iridotomy can help prevent glaucoma and protect your vision.
What are Narrow Angles?
Narrow angles, also known as angle-closure glaucoma or closed-angle glaucoma, occur when the space between the iris and cornea narrows. This narrowing creates a blockage in the eye’s drainage system, preventing fluid from flowing out properly. As a result, intraocular pressure (IOP) increases, which can damage the optic nerve and lead to irreversible vision loss.
There are two main types of narrow angles:
- Acute narrow angles – A sudden, severe condition that requires immediate medical attention to prevent blindness.
- Chronic narrow angles – A progressive form that gradually impairs vision and may not present noticeable symptoms until significant damage has occurred.
If diagnosed early, treatment such as laser iridotomy can prevent serious complications and permanent vision loss.
Laser Iridotomy Procedure: A Safe and Effective Treatment
Laser iridotomy is a minimally invasive procedure used to treat narrow angles. During the procedure, a laser is used to create a small hole in the iris, allowing fluid to flow more freely and reducing IOP. The procedure is usually performed on an outpatient basis and takes only a few minutes to complete.
Before the procedure, the patient’s eyes are numbed with local anesthesia, and a special lens is placed on the eye to focus the laser. The surgeon then uses the laser to create a small hole in the iris, typically near the top or bottom of the eye. The hole allows fluid to flow from the posterior chamber of the eye to the anterior chamber, bypassing the narrow angle and reducing IOP.
After the procedure, patients may experience mild discomfort or sensitivity to light, which can be managed with over-the-counter pain relievers and eye drops. The eye may also be red or irritated for a few days following the procedure, but this typically resolves on its own.
Benefits of Laser Iridotomy
Laser iridotomy is a safe and effective procedure for treating narrow angles and reducing IOP. The procedure has several benefits, including:
- Minimally invasive: Laser iridotomy is a minimally invasive procedure that can be performed on an outpatient basis, reducing the risk of complications associated with more invasive procedures.
- Quick recovery: Most patients recover quickly following laser iridotomy, with few side effects and minimal downtime.
- Low risk: Laser iridotomy has a low risk of complications, making it a safe and effective treatment option for narrow angles.
Conclusion
Narrow angles can lead to a variety of vision problems, including glaucoma and permanent vision loss. Laser iridotomy is a safe and effective treatment option for reducing IOP and preventing vision loss in individuals with narrow angles. If you are experiencing symptoms of narrow angles or have been diagnosed with the condition, talk to your eye care professional about the benefits of laser iridotomy and whether it may be right for you.
