Dense fibrous scar tissue blocks the central vision up to a certain degree. Nerve tissue outside the macula is not damaged. Therefore, this disease will not alter peripheral vision. Another type of macular degeneration is inherited. Infections, lesions, trauma, or diverse inflammations can also damage the delicate tissue called the macula.
Macular degeneration causes different symptoms in each person.
Sometimes only an eye loses vision while the other sees well for many years. If both eyes are affected, you can have difficulty reading or working. Macular degeneration alone doesn't cause total blindness. Since lateral vision normally is not affected, most of the patients can care for themselves. Straight lines are deformed and in some cases, the center of the image is more distorted than the rest of the image.
