  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.
  • Macular pucker is also known as epiretinal membrane, preretinal membrane, cellophane maculopathy, retina wrinkle, surface wrinkling retinopathy, premacular fibrosis, and internal limiting membrane disease.

                        

Etiology

  • 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 epiretinal 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.

Ophthalmic features

  • Vision loss from a macular pucker can vary from no loss to severe loss, although severe vision loss is uncommon.
  • People with a macular pucker may notice that their vision is blurry or mildly distorted, and straight lines can appear wavy.
  •  They may have difficulty in seeing fine detail and reading small print.
  • There may be a gray area in the center of your vision, or perhaps even a blind spot.

                            

Treatment

  • A macular pucker usually requires no treatment. In many cases, the symptoms of vision distortion and blurriness are mild, and no treatment is necessary. People usually adjust to the mild visual distortion, since it does not affect activities of daily life, such as reading and driving. Eye drops,  medications, nor nutritional supplements will improve vision distorted from macular pucker. Sometimes the scar tissue--which causes a macular pucker--separates from the retina, and the macular pucker clears up.
  • Rarely, vision deteriorates to the point where it affects daily routine activities. However, when this happens, surgery may be recommended. This procedure is called a vitrectomy in which the vitreous gel is removed to prevent it from pulling on the retina and replaced with a salt solution (Because the vitreous is mostly water, you will notice no change between the salt solution and the normal vitreous). Also, the scar tissue which causes the wrinkling is removed. A vitrectomy is usually performed under local anesthesia.
  • After the operation, you will need to use medicated eye drops to protect against infection
