Scleral Buckle Surgery for Retinal Detachment: Steps and Success Rate

Retinal detachment is an ophthalmic emergency requiring prompt surgical intervention to restore vision and prevent further damage. Among the effective and widely used surgical techniques for treating retinal detachment, scleral buckle surgery stands out as a traditional and reliable method that has proven its efficacy over decades. In this article, we review the details of this procedure, its steps, and its expected success rate, highlighting its role in preserving eye health.

What is Retinal Detachment?

Before delving into the details of scleral buckle surgery, it is essential to understand the nature of retinal detachment. This condition occurs when the light-sensitive layer at the back of the eye, the retina, separates from its supporting tissue layers. This separation prevents oxygen and nutrients from reaching the retinal cells, which can lead to permanent vision loss if not treated promptly. Retinal detachment often begins with a tear or hole in the retina, allowing fluid to seep underneath and push it away from its normal position.

Scleral Buckle Surgery: Mechanism of Action

Scleral buckle surgery relies on a simple yet highly effective mechanical principle. The surgeon attaches a flexible band, known as a "scleral buckle," around the circumference of the eyeball. This buckle, typically made of silicone or similar materials, gently indents the outer wall of the eye (the sclera). This external pressure pushes the eye wall inward, bringing it closer to the detached retina. The primary goal is to relieve the traction causing the retinal tear or hole, and to reattach the retina to its normal position, allowing it to re adhere to the supporting layers and restore its function.

This technique is particularly effective in cases of retinal detachment involving large or multiple tears, or when there is significant traction on the retina, such as in cases of severe myopia or after certain other eye surgeries. It may also be a good option for complex or recurrent retinal detachments.

Detailed Steps of Scleral Buckle Surgery

Scleral buckle surgery requires high surgical precision and expertise, and is usually performed under local or general anesthesia, depending on the patient's condition and the complexity of the detachment. The main steps can be summarized as follows:

• Anesthesia: The procedure begins with the administration of appropriate anesthesia to ensure patient comfort and pain control.
• Locating the tear: The surgeon precisely identifies the location of the retinal tears or holes, often using specialized instruments and surgical microscopy.
• Buckle placement: A silicone band or similar material is placed around the eyeball, with the optimal position determined to provide the necessary pressure to reattach the retina.
• Buckle securing: The buckle is firmly sutured around the eye to secure it in place. Special dissolvable or permanent surgical sutures may be used.
• Tear treatment: Often, the edges of the retinal tears or holes are frozen (Cryopexy) or cauterized (Laser Photocoagulation) after the buckle is placed. This procedure helps create a strong adhesion between the retina and the underlying layers, preventing future re-detachment.
• Fluid drainage (optional): In some cases, the surgeon may need to drain fluid accumulated under the retina using a fine needle, to facilitate retinal reattachment.
• Incision closure: Any small surgical incisions necessary to access the eye are closed.

The procedure typically takes one to two hours, depending on the complexity of the case.

Success Rate of Scleral Buckle Surgery

Scleral buckle surgery is considered successful in a high percentage of cases. The initial success rate, meaning reattachment of the retina immediately after surgery, often ranges between 80% and 90% in uncomplicated cases. However, some cases may require additional surgery or other techniques to achieve a satisfactory final outcome, especially if complications such as proliferative vitreoretinopathy (PVR) develop, or if there are multiple or large tears.

It is worth noting that the success rate depends significantly on several factors, including:

• The extent of the retinal detachment and the involvement of the macula (center of vision).
• The presence or absence of multiple tears or large holes.
• The presence of vitreous traction or previous complications.
• The patient's general health and age.
• The surgeon's experience and the medical facility.

At Al Mashreq Eye Center, our medical team, led by Dr. Mahmoud Hassan, strives to achieve the best possible outcomes for patients with retinal detachment using the latest advanced techniques and surgeries. Dr. Mahmoud Hassan, a specialist surgeon in vitreoretinal medicine and surgery, is a key contributor to providing excellent care at Al Mashreq Eye Center in Cairo.

Post-Surgery and Recovery

After scleral buckle surgery, the patient needs a recovery period. They may experience some pain or discomfort, which can be managed with prescribed pain relievers. The surgeon will provide detailed instructions on how to care for the eye, including the use of anti-inflammatory eye drops and antibiotics. It is important to adhere to the doctor's instructions regarding head position and permitted and forbidden activities during the recovery period.

Typically, a follow-up appointment is scheduled a few days after surgery to assess the condition of the retina and ensure there are no complications. Vision may take some time to stabilize completely, and the patient may need to adjust their glasses after a few weeks or months.

When is Scleral Buckle Surgery the Best Option?

Scleral buckling is an excellent surgical option in many cases of retinal detachment, especially when:

• The detachment is accompanied by large or multiple tears.
• There is strong traction on the retina, as in cases of severe myopia.
• Previous attempts to repair the detachment with other techniques have failed.
• The retina has begun to detach significantly towards the center of vision.

In some cases, scleral buckle surgery may be combined with other procedures such as vitrectomy to increase the chances of success, especially in complex cases. The choice of the appropriate surgical technique depends on a careful evaluation of each individual case.

Conclusion

Scleral buckle surgery remains a valuable and effective tool in the arsenal of retina surgeons for treating retinal detachment. Thanks to its direct mechanical action and ability to provide long-term support for the retina, this surgery contributes to restoring vision for hundreds of thousands of patients worldwide. Understanding the steps of the procedure, its success rate, and the recovery period helps patients make informed decisions about their treatment.
