Causes and cures of macular degeneration?

Maculardegeneration

Dry maculardegeneration is a chronic eye disease that causes vision loss in the center of your field of vision. Dry maculardegeneration is marked by deterioration of the macula (MAK-u-luh), which is in the center of the retina - the layer of tissue on the inside back wall of your eyeball.
Dry maculardegeneration is one of two types of age-related maculardegeneration. The other type - wet maculardegeneration - is characterized by swelling caused by leaky blood vessels in the back of the eye. Dry macular degeneration isn't associated with swelling and is the more-common form of the disease.
Dry macular degeneration doesn't cause total blindness, but it worsens your quality of life by blurring or causing a blind spot in your central vision. Clear central vision is necessary for reading, driving and recognizing faces.
Symptoms
Dry macular degeneration symptoms usually develop gradually. You may notice these vision changes:

• The need for increasingly bright light when reading or doing close work
• Increasing difficulty adapting to low light levels, such as when entering a dimly lit restaurant
• Increasing blurriness of printed words
• A decrease in the intensity or brightness of colors
• Difficulty recognizing faces
• A gradual increase in the haziness of your overall vision
• A blurred or blind spot in the center of your field of vision
• Hallucinations of geometric shapes or people, in cases of advanced macular degeneration

Dry maculardegeneration may affect one eye or both eyes. If only one eye is affected, you may not notice any or much change in your vision because your good eye compensates for the weak one.
When to see a doctor
See your eye doctor if:

• You notice changes in your central vision
• Your ability to see colors and fine detail becomes impaired

These changes may be the first indication of maculardegeneration, particularly if you are older than 50.
