Human eye has various important parts like Cornea, Pupil, Iris, Lens and Retina. The macula is
located in the center of the retina, the light-sensitive tissue at the back of the eye. The retina instantly
converts light, or an image, into electrical impulses. The retina then sends these impulses, or nerve
signals, to the brain. When the cells of the macula deteriorate, images are not received correctly. In
early stages, macular degeneration does not affect vision. Later, if the disease progresses, people
experience wavy or blurred vision, and, if the condition continues to worsen, central vision may be
completely lost. People with very advanced macular degeneration are considered legally
blind. Macular Degeneration is the leading cause of vision loss, more
than cataracts and glaucoma combined.
Macular degeneration is classified as:
 Dry Age related Macular Degeneration
 Wet Age related Macular Degeneration.
Pathophysiology
The dry form is more common than the wet form, with about 85 to 90 percent of AMD
patients diagnosed with dry AMD. The less common wet AMD usually leads to more serious
vision loss.
Dry AMD causes changes of the retinal pigment epithelium, typically visible as dark pinpoint
areas. The retinal pigment epithelium plays a critical role in keeping the cones and rods

2. healthy and functioning well. Accumulation of waste products from the rods and cones can
result in drusen, which appear as yellow spots. Areas of chorioretinal atrophy (referred to as
geographic atrophy) occur in more advanced cases of dry AMD. There is no elevated
macular scar (disciform scar), edema, hemorrhage, or exudation.
Dry AMD has three stages, all of which may occur in one or both eyes:
 Early AMD - People with early AMD have either several small drusen or a few medium-sized
drusen. At this stage, there are no symptoms and no vision loss.
 Intermediate AMD - People with intermediate AMD have either many medium-sized drusen
or one or more large drusen. Some people see a blurred spot in the center of their vision.
More light may be needed for reading and other tasks.
 Advanced AMD - In addition to drusen, people with advanced dry AMD have a breakdown
of light-sensitive cells and supporting tissue in the central retinal area. This breakdown can
cause a blurred spot in the center of your vision. Over time, the blurred spot may get bigger
and darker, taking more of your central vision. You may have difficulty reading or recognizing
faces until they are very close to you.
Wet AMD occurs when new abnormal blood vessels develop under the retina in a process
called choroidal neovascularization (abnormal new vessel formation). Localized macular
edema or hemorrhage may elevate an area of the macula or cause a localized retinal
pigment epithelial detachment. Eventually, untreated neovascularization causes a disciform
scar under the macula.
Symptoms
Dry macular degeneration symptoms usually develop gradually and without pain.
They may include:
 Visual distortions, such as straight lines seeming bent
 Reduced central vision in one or both eyes
 The need for brighter light when reading or doing close work
 Increased difficulty adapting to low light levels, such as when entering a dimly lit restaurant
 Increased blurriness of printed words
 Decreased intensity or brightness of colors
 Difficulty recognizing faces
What causes macular degeneration?

3. Though macular degeneration is associated with aging, there is genetic component to the
disease. A strong association between development of AMD and presence of a variant of a
gene known as complement factor H (CFH) is observed. This gene deficiency is associated
with almost half of all potentially blinding cases of macular degeneration.
Other investigators have found that variants of another gene, complement factor B, may be
involved in development of AMD.
Specific variants of one or both of these genes, which play a role in the body's immune
responses, have been found in 74 percent of AMD patients who were studied. Other
complement factors also may be associated with an increased risk of macular degeneration.
Oxygen-deprived cells in the retina produce a type of protein called vascular endothelial
growth factor (VEGF), which triggers the growth of new blood vessels in the retina.
The normal function of VEGF is to create new blood vessels during embryonic development,
after an injury or to bypass blocked blood vessels. But too much VEGF in the eye causes the
development of unwanted blood vessels in the retina that easily break open and bleed,
damaging the macula and surrounding retina.
Risk Factors
The biggest risk factor for Macular Degeneration is age. Your risk increases as you age,
and the disease is most likely to occur in those 55 and older.
Other risk factors include:
 Genetics – People with a family history of AMD are at a higher risk.
 Race – Caucasians are more likely to develop the disease than African-Americans or
Hispanics/Latinos.
 Smoking – Smoking doubles the risk of AMD.
Diagnosis
AMD is detected during a comprehensive eye exam that includes:
 Visual acuity test - This eye chart test measures how well you see at various distances.
 Dilated eye exam - Drops are placed in your eyes to widen the pupils. Your eye care
professional uses a special magnifying lens to examine your retina and optic nerve for signs
of AMD and other eye problems. After the exam, your close-up vision may remain blurred for
several hours.

4.  Tonometry - An instrument measures the pressure inside the eye. Numbing drops may be
applied to your eye for this test.
 Both forms of age - related macular degeneration (AMD) are diagnosed by funduscopic
examination. Visual changes can often be detected with an Amsler grid.
 Color photography and fluorescein angiography are done when findings suggest wet AMD.
Angiography shows and characterizes subretinal choroidal neovascular membranes and can
delineate areas of geographic atrophy. Optical coherence tomography (OCT) aids in
identifying intraretinal and subretinal fluid and can help assess response to treatment.
What Treatments Are Available for Macular
Degeneration?
There’s no cure for macular degeneration. Treatment may slow it down or keep you from
losing too much of your vision. Your options might include:
 Lifestyle changes - like dieting, exercise, avoiding smoking, and protecting your eyes from
ultraviolet light.
 Anti-angiogenesis drugs - These medications – aflibercept (Eylea), bevacizumab
(Avastin), pegaptanib (Macugen), and ranibizumab (Lucentis) -- block the creation of blood
vessels and leaking from the vessels in your eye that cause wet macular degeneration.
Many people who’ve taken these drugs got back vision that was lost. You might need to
have this treatment multiple times.
 Laser therapy - High-energy laser light can destroy abnormal blood vessels growing in your
eye.
 Photodynamic laser therapy - Your doctor injects a light-sensitive drug verteporfin
(Visudyne) into your bloodstream, and it’s absorbed by the abnormal blood vessels. Your
doctor then shines a laser into your eye to trigger the medication to damage those blood
vessels.
 Low vision aids - These are the devices that have special lenses or electronic systems to
create larger images of nearby things. They help people who have vision loss from macular
degeneration make the most of their remaining vision.
 Submacular surgery - This removes abnormal blood vessels or blood.

5.  Retinal translocation - A procedure to destroy abnormal blood vessels under the center of
your macula, where your doctor can’t use a laser beam safely. In this procedure, your doctor
rotates the center of your macula away from the abnormal blood vessels to a healthy area of
your retina. This keeps you from having scar tissue and more damage to your retina. Then,
your doctor uses a laser to treat the abnormal blood vessels.
