Scar tissue in the macula, the area of the retina responsible for sharp central vision. The scar can blur and distort vision and make straight lines appear wavy. Macular pucker is due most often to age-related shrinkage of the vitreous which pulls away from the retina, causing the retina to scar and wrinkle. Other causes of macular pucker include trauma (from surgery or an eye injury), retinal detachment, inflammation, and problems with the retinal blood vessels. The only treatment is surgery which consists of a vitrectomy (removal of the vitreous) combined with peeling away of the scar tissue. Most patients recover about half of their lost vision, and distortion is significantly reduced. The most common complication of vitrectomy is an increase in the rate of cataract development. Also called epiretinal membrane, retinal wrinkling, premacular fibrosis, and cellophane maculopathy.

Any pathologic condition or disease of the macula, the small spot in the retina where vision is keenest. Also called maculopathy.

The macula is a special area in the center of the retina, the light-sensitive layer of tissue at the back of the eye. As we read, light is focused onto our macula. There, millions of cells change the light into nerve signals that tell the brain what we are seeing. This is called our macular […]
A circumscribed change in the color of skin that is neither raised nor depressed. Macules are completely flat and can only be appreciated by visual inspection and not by touch. Physicians refer to flat skin spots on the skin as macules, as opposed to papules.
Small circumscribed changes in the color of skin that are neither raised (elevated) nor depressed. Macules are never large. They are basically little spots or blemishes in the skin. They are entirely flat and can only be appreciated by visual inspection; they cannot be seen from the side. Dermatologists call small flat skin spots on […]
