GLAUCOMA SURGERY

Glaucoma is a group of eye conditions that damage the optic nerve, often due to increased pressure within the eye, called intraocular pressure. This pressure can occur when the fluid inside the eye (aqueous humor) doesn’t drain properly, leading to a buildup and causing damage to the optic nerve. Glaucoma can result in vision loss and, if left untreated, may lead to irreversible blindness.

Glaucoma surgery aims to alleviate this pressure and prevent further damage to the optic nerve. Various types of surgeries are available, each with the goal of improving the drainage of fluid from the eye or reducing its production.

What are different forms of Glaucoma?

What are different forms of Glaucoma?

There are two main forms of glaucoma: open-angle (the most common form, affecting approximately 70-90% of individuals); and angle-closure. There are also several other forms of glaucoma, including normal-tension, congenital, juvenile, and secondary.

Who is at risk of developing Glaucoma?

Glaucoma is a leading cause of blindness among African Americans and Hispanics in the U.S. Three times as many African Americans have glaucoma than Caucasians, and four times as many are blind. Between the ages of 45 and 64, glaucoma is fifteen times more likely to cause blindness in African Americans than in Caucasians. All people older than 60 are at a greater risk of developing glaucoma than people who are younger.

Is there a cure for Glaucoma?

No, but there are sight-saving treatments. So the sooner a person is diagnosed, the more vision can be preserved. The most common treatments for glaucoma are eye drops and, rarely, pills. A doctor can decide which medications are best suited for a patient based on the individual case of glaucoma, medical history, and current medication regimen. 

What is considered Normal eye pressure?

Unfortunately, the answer is not any single number. While the average eye pressure is approximately 15, the range of normal eye pressure is much larger. About 90 percent of people will fall between a pressure of 10 and 21. Even so, this does not mean that if you have a pressure of 22 or higher it is abnormal. Every individual and every eye is different. There are many patients with pressures in the mid-20s who do not have glaucoma, and they can be followed with routine eye examinations by their eye care specialist. There are also patients who have been diagnosed with glaucoma and yet, even though treatment may decrease their pressure below 22, they still experience worsening of their glaucoma. 

It is important that you see an eye care specialist to receive a thorough examination and determine if your eye pressure is problematic

What is a GLAUCOMA?

Glaucoma is a progressive eye condition characterized by damage to the optic nerve, often associated with elevated pressure within the eye.

This damage to the optic nerve can result in vision loss and, if left untreated, may lead to irreversible blindness. Glaucoma typically develops gradually and is often asymptomatic in its early stages, making regular eye examinations crucial for early detection and management.

There are various types of glaucoma, each with its own set of risk factors and treatment approaches, but the common goal in managing glaucoma is to reduce intraocular pressure to prevent further damage to the optic nerve and preserve vision.

A Modern Approach
to
GLAUCOMA Surgery

Modern day glaucoma surgery has seen significant advancements in recent years, providing more effective and safer treatment options for patients. Some of the modern surgical techniques used to treat glaucoma include:

1. Minimally Invasive Glaucoma Surgery (MIGS): MIGS procedures are performed using tiny incisions and specialized instruments. 

2. Laser Trabeculoplasty: This procedure uses a laser to improve the drainage of fluid from the eye by treating the trabecular meshwork.

3. Glaucoma Drainage Devices: These devices, such as the Ahmed valve or Baerveldt tube, are implanted in the eye to create a new drainage pathway for excess fluid. 

4. Minimally Invasive Suprachoroidal Shunt (MIGS): This procedure involves the implantation of a tiny tube into the suprachoroidal space, which allows the excess fluid to drain out of the eye. 

5. Cyclophotocoagulation: This laser procedure targets the ciliary body, which produces the fluid inside the eye.  

It is important to consult with an ophthalmologist to determine the most suitable surgical option for each individual case of glaucoma.

What is “Advanced”
GLAUCOMA Surgery?

Advanced glaucoma surgery refers to surgical procedures that are typically reserved for cases of glaucoma that are more severe or have not responded well to other treatment options. These surgeries are often considered when traditional methods, such as medications and laser treatments, have not effectively controlled intraocular pressure (IOP) or when the optic nerve is at significant risk of further damage.

Some examples of advanced glaucoma surgeries include:

1. Trabeculectomy: It involves making a small flap in the sclera (white part of the eye) and creating a reservoir under the conjunctiva (thin, transparent tissue covering the sclera) to collect the fluid.

2. Tube Shunt Implantation:  This involves placing a small tube with a silicone or polypropylene drainage device into the eye to help drain fluid and reduce IOP. The tube is connected to a small plate that is positioned under the conjunctiva to allow for fluid drainage.

3. Deep Sclerectomy: This procedure involves removing a smaller portion of the sclera. It creates a new drainage pathway by removing part of the trabecular meshwork and the inner wall of Schlemm’s canal. A thin layer of tissue called the scleral flap is then created to cover the opening, allowing fluid to drain out while maintaining the structural integrity of the eye.

4. EXPRESS Shunt: This is a minimally invasive glaucoma surgery that involves implanting a small stainless-steel shunt into the eye to create a controlled drainage pathway.

5. Xen Gel Stent: This is a newer surgical option that involves implanting a small gel stent made of porcine collagen into the eye. The stent creates a pathway for fluid to drain out, reducing IOP.

 It is important to discuss the potential risks, benefits, and alternatives of advanced glaucoma surgeries with an ophthalmologist to determine the most appropriate course of action.
