Trabeculectomy

Trabeculectomy surgery

Trabeculectomy surgery is a procedure used to treat glaucoma, a group of eye conditions that cause damage to the optic nerve and can lead to vision loss or blindness. The goal of trabeculectomy surgery is to reduce intraocular pressure (IOP) by creating a new drainage pathway for aqueous humor (the fluid in the eye).

During the surgery, the surgeon creates a small flap in the sclera (the white part of the eye) and removes a portion of the trabecular meshwork (the drainage system of the eye) underneath. This creates a new pathway for aqueous humor to flow out of the eye and helps to lower the IOP. A small bubble, called a bleb, may form under the conjunctiva (the thin layer that covers the sclera) as a result of the surgery, which allows the aqueous humor to drain out of the eye.

Trabeculectomy surgery is typically performed under local anesthesia and takes about 30 to 45 minutes. After the surgery, patients may need to use eye drops and wear an eye patch for a few days to help with healing. They may also need to avoid certain activities, such as heavy lifting or strenuous exercise, for several weeks after the surgery.

As with any surgical procedure, there are potential risks and complications associated with trabeculectomy surgery, including infection, bleeding, and vision loss. However, the procedure is generally considered safe and effective for lowering IOP and treating glaucoma. Your doctor can discuss the risks and benefits of the surgery with you and help you determine if it is the right treatment option for your specific situation.

Trabeculectomy technique

Trabeculectomy is a surgical procedure used to treat glaucoma by lowering intraocular pressure (IOP).

The following are the general steps involved in the trabeculectomy technique :

Anesthesia : Before the surgery, local anesthesia is administered to numb the eye and surrounding area ;
Creation of a conjunctival flap : A small incision is made in the conjunctiva, the thin layer that covers the sclera (white part of the eye), and a flap is created to expose the underlying tissue ;
Scleral flap creation : A partial-thickness scleral flap is created by making an incision into the sclera, usually about 3mm x 3mm in size ;
Trabeculectomy : Using microsurgical instruments, the surgeon carefully removes a small piece of the trabecular meshwork, the tissue that drains fluid from the eye ;
Iridectomy : A small opening is made in the iris, the colored part of the eye, to allow for better fluid flow ;
Closure of the scleral flap : The scleral flap is carefully closed and sutured to create a new drainage pathway for aqueous humor (the fluid in the eye) ;
Creation of a bleb : A small bubble, called a bleb, may form under the conjunctiva as a result of the surgery. The bleb allows aqueous humor to drain out of the eye, further reducing intraocular pressure ;
Closure of the conjunctival flap : The conjunctival flap is closed and sutured to cover the surgical site ;

After the surgery, patients may need to use eye drops and avoid certain activities for several weeks while the eye heals. Regular follow-up appointments with the eye doctor are important to monitor the eye’s progress and adjust treatment as needed.

Trabeculectomy cost

The cost of a trabeculectomy procedure can vary depending on several factors, including the geographic location, the healthcare provider performing the surgery, and the patient’s insurance coverage.

In Tunisia, the average cost of a trabeculectomy procedure can range from $1,500 to $2,500 or more, depending on the location and the provider. This cost usually includes the surgical fees, anesthesia, and post-operative care.

In addition to the initial cost of the procedure, patients may also need to consider ongoing expenses for follow-up visits, medications, and additional treatments to manage their glaucoma.

Overall, the cost of a trabeculectomy procedure can be significant, but it is important to consider the potential benefits of the surgery in improving vision and preventing vision loss from glaucoma. Patients should discuss the potential costs and insurance coverage with their healthcare provider to make an informed decision about treatment options.

It is important to ask any questions you may have and fully understand the procedure and its potential risks and benefits before deciding to proceed with the surgery. Your healthcare provider can help guide you through the process and provide personalized recommendations based on your individual needs and circumstances.

How is a trabeculectomy performed ?

A trabeculectomy is typically performed as an outpatient procedure, and it generally involves the following steps :

Anesthesia : Before the procedure, local anesthesia is administered to numb the eye and surrounding area ;
Conjunctival flap : A small incision is made in the conjunctiva, which is the thin layer that covers the sclera (white part of the eye), and a flap is created to expose the underlying tissue ;
Scleral flap : A partial-thickness scleral flap is created by making an incision into the sclera, which is usually about 3mm x 3mm in size ;
Trabeculectomy : The surgeon carefully removes a small piece of the trabecular meshwork, which is the tissue that drains fluid from the eye, using microsurgical instruments ;
Iridectomy : A small opening is made in the iris, which is the colored part of the eye, to allow for better fluid flow ;
Closure of the scleral flap : The scleral flap is carefully closed and sutured to create a new drainage pathway for aqueous humor (the fluid in the eye) ;
Bleb formation : A small bubble, called a bleb, may form under the conjunctiva as a result of the surgery. The bleb allows aqueous humor to drain out of the eye, further reducing intraocular pressure ;
Conjunctival flap closure : The conjunctival flap is closed and sutured to cover the surgical site ;

After the procedure, the patient will be monitored for a short time to ensure that there are no complications, and then they will be discharged with instructions for post-operative care. These may include the use of eye drops or other medications, avoiding certain activities that may increase intraocular pressure, and scheduling follow-up appointments with the healthcare provider to monitor healing and adjust treatment as necessary.

Overall, trabeculectomy is a relatively safe and effective procedure for lowering intraocular pressure and managing glaucoma, and it can help to preserve vision and improve overall eye health.
