There are limited options for preventing graft shrinkage and scarring in this situation. The oldest and most commonly used technique is injection of steroid medication. Steroids decrease proliferation of a fibroblast cells, which create collagen and glycosaminoglycan, two proteins created by the body that contract and cause graft shrinkage. Data in literature shows that one form of steroid, triamcinolone, is effective for this purpose. However, there is a risk of embolization of this solid steroid material that care rarely cause blindness. In addition, in the periocular area, steroids can elevate eye (intraocular) pressure (that can cause glaucoma in some cases) and accelerate the formation of cataracts.
