Macular degeneration
* advances very slowly in some people and has almost no effect on their vision.
* affects central vision for reading and driving.
* affects only the center vision
  - central part of vision
  - the part of the eye called the macula
* begins when abnormal deposits accumulate under the retina.
* can cause different symptoms in different people
  - vision distortion even with glasses
  - result in central vision blindness
  - ruin sharp vision needed to see objects clearly and to do common tasks
* causes central vision to become blurry, but peripheral vision is left intact
  - damage to the macula of the eye
* causes different symptoms in each person
  - loss of the central part of the visual field, making reading impossible
  - sight- sensing cells in the macular zone of the retina to breakdown
* comes in two forms, dry and wet.
* common cause of legal blindness in older people
  - degenerative condition in the retina of the eye
  - effect of aging
* condition resulting in vision loss.
* condition that affects one out of every three seniors
  - the macula, the central part of the retina
* consists of injury to the macula, and leads to a severe loss in vision.
* decreases the vision of the central part of the retina.
* destroys the central part of the retina.
* develops differently in each person.
* differs from detached retina in that the edges of the retina stay in place.
* disease of the retina.
* group of chronic diseases which cause breakdown of the macular tissues.
* is already the leading cause of blindness in individuals over age sixty five
  - an eye disease
  - another condition where laser can sometimes help prevent vision loss
* is caused by abnormal or leaky blood vessels behind the eye
  - aging and thinning of the tissues of the macula
  - characterized by loss of central vision, usually in both eyes
  - classified into two varieties
  - common in the elderly and is considered a process of aging
  - damage or breakdown of the macula of the eye
  - degeneration
  - illnesses
  - most commonly a natural result of the aging process
  - now the leading cause of blindness in the elderly
* is one of the commonest causes of vision loss in older adults
  - leading causes of decreased vision in the United States
  - painless
* is the commonest cause of blindness in the elderly
  - gradual loss of vision that usually affects the elderly
* is the leading cause of blindness in the United States
  - central vision loss in adults
  - eye blindness
* is the leading cause of legal blindness in the United States
  - blindness in the senior population
  - loss of vision for people over sixty-five
  - severe vision loss in both the USA and in Europe
* is the leading cause of vision loss among the senior population
  - loss in the United States
  - least understood and also the least researched of all the eye diseases
  - most prevalent cause of visual impairment in developed countries
  - nation's leading cause of serious vision impairment
  - physical disturbance of the center of the retina called the macula
  - primary disease behind the loss of vision in aging adults
  - second leading cause of blindness in senior citizens
  - typically age-related and can be hereditary
* is, literally, degeneration of the spot.
* major cause of blindness and visual impairment in the United States.
* makes close work like threading a needle, or reading difficult or impossible
  - lipreading and reading of finger alphabet difficult
* rare eye disorder.
* sight-threatening, lifelong disease.
* steals central vision.
* varies widely in severity.
