Macular Degeneration
Maggie & Jay
As many as 11 million people in the America have some form of macular degeneration. This number is expected to double to nearly 22 million by 2050.
Basic Eye Function
2 TYPES OF
MACULAR
DEGNERATION
Age-related Macular Degeneration (AMD) or dry MD
AMD is a common cause of visual loss in older people.

The predisposing factors are a combination of genetics factors and environmental exposure such as drugs and ultraviolet rays.

Deposits of drusen (cell debris) are formed in the retinal cells and gradually destroy the cones in the macula.
Wet or Exudative form of MD
Occurs due to neovascularization, which is the excessive ingrowth of leaky blood vessels that will rapidly destroy the retina. Wet MD may occur to someone that already has a dry MD. “Wet” macular degeneration is considered a more serious form of the disease. It is more detrimental to eye sight.
SYMPTOMS
Initially there might not be any symptoms. But as the disease gradually worsens blurred vision might be noticed. In a dry AMD things in the central vision look dim, blurred, distorted, and the color begins to fade. In wet MD straight lines appear wavy and distorted. A small dark spot may appear in the central vision and can increase in size.
TESTING FOR MD
Amsler Grid
normal
MD
Dilation
Fluorescein Angiogram
Optical Coherence Tomography (OCT Scan)
SO ARE THERE ANY CURES TO MD?
NONE,
BUT...
Future Treatments
Anti VEGF Agents:
Magugen, Avastin, and Eylea
New treatments involve injections of anti VEGF agents. Induces angiogenesis (new blood vessel formation).
Macula Risk:
In the future genetic testing will help predict those at risk.
Normal RPE
Bulging RPE
Spinach and other green
vegetables have shown
dramatically decrease in odds of getting MD.
Stem Cell
Earlier Detection
Slow Growth of MD
Diet & Healthy Living
THE END
