The macula normally lies flat against the back of the eye, like a movie screen being projected on. When wrinkles, creases or bulges form on the macula, these formations are known as macular pucker.

As you age, the vitreous-the clear, gel-like substance that fills the middle of your eye- begins to shrink and pull away from the retina. As the vitreous pulls away, scar tissue may develop on the macula. Sometimes the scar tissue may develop on the macula. Sometimes the scar tissue can warp and contract, causing the retina to wrinkle or bulge. Macular pucker is associated with vitreous detachment, detached or torn retina, inflammation inside the eye and disorders of the blood vessels in the retina.
Triamcinolone is a steroid. An intravitreal injection of triamcinolone may be performed to treat macular Edema (swelling of the macula). The cause of the macular edema may be related to macular degeneration, diabetic eye disease or post-operative inflammation. The steroid acts to reduce the amount of accumulated fluid and thus settle the inflammation.
