ABOUT RETINAL SURGERY
WHAT IS A RETINAL DETACHMENT?
The retina is the nerve layer covering the inner surface of the posterior segment of the eye. It is vitally important for vision, it contains millions of light receptors that capture light rays from our environment. It is like the film inside a camera.
Posterior segment of the eye is filled with a jelly-like substance called the vitreous. This jelly supports the retina from the inside, and is firmly attached to the retinal surface. As we age the vitreous starts to liquefy, resulting in traction on the retina and in some cases retinal detachment.
If the retina is detached from the underlying layers, it cannot function as it has reduced blood supply. The retina detaches and starts to contract and scar, eventually leading to permanent visual loss, if not treated as soon as possible.
WHY RETINAL SURGERY?
Retinal surgery needs to be performed as soon as possible to prevent permanent visual loss. The choice of surgery is determined by the age of the patient, the lens status, the location and size of the detachment and numerous other factors.
Pars plana vitrectomy or PPV is performed mostly in our center.
Dr Goosen will advise if gas or silicone oil will be used at he time of surgery to keep the retina flat.
IS LASER FOR YOU?
Laser retinopexy can be performed in the rooms if a retinal tear is present without a detachment. These cases are treated in the rooms with the argon laser to "spot weld" around the retinal break. This prevents detachment in a large percentage of patients.
