There are many diseases and problems related to the eye but here
are the most common. See more information on all of these diseases
in the Eyehealth Links of this website.
An estimated 13 million Americans have
signs of this sight-threatening disease, the world's number-one
cause of blindness. Treatment options, sadly, are limited. People
that have this disease lose their central vision but still have some
or limited peripheral vision.
A cataract is a clouding of the eye's lens which usually occurs
as one ages due to protein changes in the eye. When the vision is
obstructed to the point where it interferes with daily routines,
cataract surgery is recommended.
Inflammation due to a virus or bacteria in the
outer membrane of the eye can cause redness, swelling, itching and
tearing. It can be infectious and spread to the other eye or family
Changes occur in the eye when high blood
sugar levels due to diabetes are not controlled properly. In late
stages of diabetes, new blood vessels form around the capillaries in
your retina which can lead to scar tissue that can eventually lead
to retinal detachment.
Sometimes the eye doesn't produce enough tears, or
the tears have a chemical composition that causes them to evaporate
too quickly. This is usually most noticeable with contact lens
Glaucoma causes chronic damage to the optic nerve and a
gradually diminished field of vision. Drops every day and sometimes
surgery are necessary to keep the eye pressure down.
Age Related Macular Degeneration
researchers and optometrists believe that antioxidant vitamins, such
as beta carotene (vitamin A) and vitamins C and E, may protect the
macula from damage. Reducing blood pressure, stop smoking and losing
weight are other ways to lower the chances of macula degeneration.
Wearing good sunglasses, avoiding
cigarette smoke, air pollution and heavy alcohol consumption can
reduce chances of cataracts. Many researchers also believe that a
diet high in antioxidants such as beta carotene (vitamin A),
selenium and vitamins C and E may slow down cataracts.
Avoiding viral and bacterial
conjunctivitis includes washing hands frequently and avoid touching
or rubbing your eyes. Don't share washcloths, towels or cosmetics
that are used near the eyes with others.
Sometimes dry eyes are caused by
medications such as antihistamines, birth control pills or cold
medications. Avoiding or changing medications can sometimes help.
Using over the counter lid scrubs or a Q-tip dipped in baby shampoo
to wash the eyelids can also help with dry eyes.
The very best way to prevent
glaucoma is early detection with frequent eye examinations
especially for those at higher risk.
