Giant Retinal Tear.

Just as vitreous pulling creates small retinal tears, it can also cause very large retinal tears. If the retinal tear is very large (one quarter of the retina or more), it is called a "giant retinal tear". Occasionally, the tear is so large that the retina folds over on itself, like a piece of paper folded in half. A giant retinal tear is a very serious problem.

Vitreous surgery, scleral buckling and laser treatment may be used to treat giant retinal tears. The lens of the eye is usually removed to make this surgery successful. The goal of the surgery is to unfold the retina, put it back in place, and seal it into its proper position. Silicone oil or fluids that are heavier than water (called perfluorocarbons) may be used to unfold a giant retinal tear and reattach the retina.

Many patients will see well after surgery for a giant retinal tear, but some will not. Most will recover enough vision to get around. Despite modern techniques to reposition the folded retina and hold it into place, many eyes develop scar tissue (proliferative vitreoretinopathy) after the surgery and the retina again becomes detached. Your surgeon will discuss with your chances for regaining some vision with this surgery, as well as the possible complications.
