GERIATRIC EYE CARE
Today, the three
most common eye conditions that older people face
are : -
CATARACTS
A cataract is a
cloudy or opaque area on the lens of the eye. A
person with a
cataract in the early stages rarely
notices changes in vision, but as the cataract
continues to change the lens of the eye, vision may
be blurred, distorted or sensitive to light and
glare.
Medicines won’t
cure cataracts. The only treatment is surgery in
which affected eye lens is removed and replaced with
an implanted plastic lens. If the cataract develops
after surgery, the affected eye can be treated with
laser surgery.
Studies show
that exposure to ultraviolet (UV) light - a
component of sunlight ?can worsen the chance of
developing cataracts, and managing the disease
properly can help ward off cataracts.
GLAUCOMA
Glaucoma is damage to the optic nerve that causes
blind spots to develop. The damage occurs when the
pressure in the eye builds up and decreases the flow
of fluid in and out of the eye. In glaucoma’s early
stages, vision is left virtually unchanged. But when
glaucoma becomes more severe, small blind spots in
the peripheral vision begin to occur. Other symptoms
include blurred vision, severe eye pain, headaches,
halos around lights, nausea and vomiting.
Glaucoma cannot be cured, but lowering the pressure
inside the eye with medication or surgery can
control it. Regular eye exams are necessary to help
prevent further optic nerve damage.
Unavoidable factors such as age, hereditary and race
contribute to glaucoma, so the only way to avoid
glaucoma is to have regular eye exam, reduce
your risk of eye injury and avoid medications that
contain steroids unless a health care provider
prescribes or recommends one.
MACULAR
DEGENERATION
The
macular is a section in the centre of the retina
that helps us see fine details in the centre of our
field of vision. As we age, the macular tissues
thinned, causing mild vision loss that usually
results in problems when reading. But in 10% of
macular degeneration cases - categorized as “wet?
macular degeneration ?new blood vessels grow
beneath the retina and cause blind spots in the
centre of the field of vision . Other symptoms
include blurry or fuzzy vision, straight lines that
appear wavy and dark or empty areas in the centre of
vision.
Only
wet macular degeneration can be treated with laser
surgery to help destroy abnormal blood vessels
around the macula. For people with “dry?macular
degeneration, low vision aids ?such as
magnification and bright lights - can help them see
better.
