Laser Peripheral Iridotomy (LPI) Surgery for Narrow Angles
When it comes to eye health, early detection and timely treatment of certain conditions can significantly impact vision preservation. One such condition that requires prompt attention is narrow angles, a structural issue that can lead to a severe form of glaucoma called acute angle-closure glaucoma. Laser Peripheral Iridotomy (LPI) surgery is an advanced treatment used to prevent or address this problem.
What Are Narrow Angles?
The eye contains a fluid known as aqueous humor, which continuously circulates and drains through a structure called the drainage angle. When this angle becomes too narrow, it can impede the fluid’s flow, leading to increased pressure within the eye. Over time, this increased intraocular pressure can damage the optic nerve, resulting in glaucoma.
Individuals with narrow angles are at higher risk of developing angle-closure glaucoma, a medical emergency that occurs when the drainage angle becomes completely blocked, causing a sudden rise in eye pressure. Without immediate intervention, this condition can lead to permanent vision loss.
What is Laser Peripheral Iridotomy (LPI)?
Laser peripheral iridotomy is a minimally invasive procedure designed to prevent or treat angle-closure glaucoma. The goal of LPI is to create a tiny hole in the outer edge of the iris. This small opening allows the fluid to flow more freely, reducing pressure and preventing the drainage angle from closing off entirely. LPI is most often recommended for patients with narrow angles or those who have experienced an acute angle-closure glaucoma attack.
Who is a Candidate for LPI?
LPI is typically recommended for patients with narrow angles who are at risk of developing angle-closure glaucoma. It may also be suggested for those who have already experienced an angle-closure attack. Your ophthalmologist will perform a detailed eye examination, including tests to measure your eye pressure and the width of your drainage angles, to determine whether you are a candidate for this procedure.
What to Expect During the LPI Procedure
LPI is typically performed as an outpatient procedure and takes only a few minutes per eye. Here's a general overview of what you can expect during the surgery:
Pre-Surgery Preparation: Before the procedure, your ophthalmologist will apply eye drops to numb the eye and reduce the size of your pupil. These drops ensure you remain comfortable during the procedure.
The Laser Treatment: Using a special laser, your ophthalmologist will carefully create a small opening in the peripheral part of the iris. You may see bright flashes of light during this step, but it should not be painful.
Post-Surgery Care: After the procedure, you may receive anti-inflammatory eye drops to minimize any discomfort or inflammation. Most patients can resume normal activities within a day or two but should follow their doctor’s advice on when to return to work or strenuous activities.
What Are the Benefits of LPI Surgery?
Prevention of Angle-Closure Glaucoma: The most significant benefit of LPI is its ability to prevent the progression of narrow angles into a sight-threatening condition like angle-closure glaucoma.
Quick and Painless: The procedure itself is fast and virtually painless, with most patients experiencing minimal discomfort afterward.
Long-Lasting Results: Once performed, the effects of LPI are typically permanent, ensuring that fluid flows properly through the eye and reducing the risk of future problems.
