Comparing Traditional vs. Minimally Invasive
Retinal Detachment Surgery
Retinal detachment (RD) is defined as an emergency situation in which a thin layer of tissue
(the retina) at the back of the eye pulls away from its normal position. RD separates the retinal
cells from the layer of blood cells that provide nourishment and oxygen to the eye.
You may need traditional or minimally invasive retinal detachment surgery to reattach your
retina to the back of your eye within a few days. This blog will explore and compare traditional
retinal detachment surgery with minimally invasive alternatives.
Traditional Retinal Detachment Surgery (Scleral Buckle
Surgery)
Traditional retinal detachment surgery, or scleral buckle surgery, has a long history of success
in repairing retinal detachments. Here's how it works:
●
Anesthesia: Requires general or local anesthesia to ensure patient comfort.
●
Incisions: The surgeon makes one or more small incisions in the eye's outer layers,
called the sclera.
●
Scleral Buckle: A silicone band or sponge is placed around the eye, pressing against
the sclera to create an indentation. This indentation helps to seal the retinal tear or
detachment.
●
Drainage of Fluid: If there is excess fluid beneath the retina, the surgeon may drain it to
reattach the retina properly.
●
Closing the Incisions: The incisions are closed with sutures, and the eye is usually
covered with an eye patch.
Pros of Traditional Retinal Detachment Surgery:
●
●
●
Scleral buckle surgery has a high success rate in repairing retinal detachments.
The procedure often results in a stable, permanent reattachment of the retina.
It doesn't require advanced surgical equipment.
Minimally Invasive Retinal Detachment Surgery
Minimally invasive retinal detachment surgery includes techniques like vitrectomy and
pneumatic retinopexy. These procedures offer a less invasive alternative to traditional surgery:
●
Vitrectomy: Removes the vitreous gel from the eye and replaces it with a gas or silicone
oil bubble that helps push the retina back into place.
●
Pneumatic Retinopexy: In this technique, a gas bubble is injected into the eye. Patients
must maintain a specific head position to keep the gas bubble in contact with the
detached retina, allowing it to reattach.
Pros of Minimally Invasive Retinal Detachment Surgery:
●
●
●
Patients often experience quicker postoperative recovery and return to daily activities
sooner.
Minimally invasive procedures tend to cause less discomfort than traditional surgery.
Smaller incisions reduce the risk of infection and improve cosmetic outcomes.
The Bottom Line
Traditional scleral buckle surgery remains a reliable and effective method with a proven track
record of success, especially for complex cases. On the other hand, minimally invasive
procedures like vitrectomy and pneumatic retinopexy offer advantages in terms of quicker
recovery and reduced discomfort.
Ultimately, the type of surgery you need depends on several things, your doctor can
recommend what type of surgery you need and the benefits and risks of the surgery.
