Gonioplasty (Iridoplasty) - A Surgical Procedure to Treat Narrow Angle Glaucoma

Understanding the Purpose, Procedure, Recovery, and Potential Risks and Benefits of Gonioplasty

Gonioplasty, also referred to as iridoplasty, is a surgical procedure primarily used in the treatment of narrow angle glaucoma. Narrow angle glaucoma is a type of glaucoma that occurs when the drainage angle between the iris and the cornea is blocked or obstructed, leading to an increase in eye pressure. Gonioplasty aims to widen the drainage angle, allowing for better fluid outflow and reducing intraocular pressure.

Purpose: The primary purpose of gonioplasty is to relieve the symptoms and prevent the progression of narrow angle glaucoma. By widening the drainage angle, the procedure helps to improve the flow of aqueous humor, the fluid that circulates within the eye. This decrease in intraocular pressure can alleviate symptoms such as eye pain, redness, blurred vision, and prevent potential damage to the optic nerve, which could lead to vision loss if left untreated.

Procedure: Gonioplasty is typically performed under local anesthesia and may be carried out as an outpatient procedure. During the surgery, the ophthalmologist uses a laser or surgical instruments to make small incisions in the peripheral iris, which is the colored part of the eye. These incisions allow the iris to relax and move away from the drainage angle, widening it and improving fluid outflow. The specific technique used may vary depending on the individual patient's needs and the surgeon's preference.

Recovery: Following gonioplasty, patients may experience mild discomfort, light sensitivity, or blurry vision, which usually subside within a few days. Eye drops or medications may be prescribed to manage any pain or inflammation. It is essential to follow the post-operative instructions provided by the ophthalmologist, including avoiding strenuous activities and keeping the eye clean to promote healing. Regular follow-up appointments will be scheduled to monitor progress and adjust medications if necessary.

Risks and Benefits: As with any surgical procedure, gonioplasty carries certain risks, although they are generally rare. Potential risks include infection, bleeding, damage to the surrounding structures of the eye, or a temporary increase in eye pressure. However, the benefits of gonioplasty can significantly outweigh these risks. By successfully widening the drainage angle, the procedure can effectively manage narrow angle glaucoma, reducing the need for ongoing medication and potentially preventing further vision loss.

In conclusion, gonioplasty, also known as iridoplasty, is a surgical procedure used to treat narrow angle glaucoma. By widening the drainage angle through small incisions in the iris, gonioplasty helps to improve fluid outflow and lower intraocular pressure. While the procedure carries some risks, it can offer substantial benefits by relieving symptoms, preserving vision, and reducing reliance on medication. If you suspect you have narrow angle glaucoma, consult with an ophthalmologist to determine if gonioplasty is a suitable treatment option for you.
