The retina is like the film of the camera which sends the image to the brain for processing. A damaged retina can lead to significant visual disturbances many of which may become permanent if not treated in time. The retinal diseases are some of the most common causes of a permanent loss of vision in many patients, if not treated on time.
Physicians perform three types of eye surgery for actual retinal detachment: vitrectomy, scleral buckling, and pneumatic retinopexy. Pars plana vitrectomy (PPV or vitrectomy involving removal of the vitreous gel of the eye) is the most common surgery performed for a retinal detachment today.
