Macular Pucker also
known as Epiretinal membrane, pre-retinal membrane, cellophane
maculopathy, retina wrinkle, surface wrinkling retinopathy,
pre-macular fibrosis, and internal limiting membrane disease.
What is a macular pucker?
A macular pucker is scar tissue that has formed on the eye's
macula, located in the center of the eye's light-sensitive
tissue called the retina. The macula provides the sharp, central
vision we need for reading, driving, and seeing fine detail. A
macular pucker can cause blurred and distorted central vision.
Most of the eye's interior is filled with vitreous, a gel-like
substance that fills about 80 percent of the eye and helps it
maintain a round shape. The vitreous contains millions of fine
fibers that are attached to the surface of the retina. As we
age, the vitreous slowly shrinks and pulls away from the retinal
surface. This is called a vitreous detachment, and is normal. In
most cases, there are no adverse effects, except for a small
increase in floaters, which are little "cobwebs" or specks that
seem to float about in your field of vision.
However, sometimes when the vitreous pulls away from the retina,
there is microscopic damage to the retina's surface (Note: This
is not a macular hole). When this happens, the retina begins a
healing process to the damaged area and forms scar tissue, or an
epi-retinal membrane, on the surface of the retina. This scar
tissue is firmly attached to the retina surface. When the scar
tissue contracts, it causes the retina to wrinkle, or pucker,
usually without any effect on central vision. However, if the
scar tissue has formed over the macula, our sharp, central
vision becomes blurred and distorted.
