Did
you know that many older people have good eyesight into their
80s and beyond? Growing older does not always mean you see
poorly. But age brings changes that can weaken your eyes.
There
are some easy things to try when these changes happen. You might
add brighter lights in more places around the house -- like at
work counters, stairways, and favorite reading places. This may
help you see better and can sometimes prevent accidents caused
by weak eyesight.
While
older people have more eye problems and eye diseases than younger
people, you can prevent or correct many of them by:
- Seeing
your doctor regularly to check for diseases like diabetes, which
could cause eye problems if not treated.
- Having
a complete eye exam with an eye specialist every 1 to 2 years.
Most eye diseases can be treated when they are found early.
The eye doctor should enlarge (dilate) your pupils by putting
drops in your eyes. This is the only way to find some eye diseases
that have no early signs or symptoms. The eye doctor should
test your eyesight, your glasses, and your eye muscles. You
should also have a test for glaucoma.
- Taking
extra care if you have diabetes or a family history of eye disease.
Have an eye exam through dilated pupils every year. See an eye
doctor at once if you have any loss or dimness of eyesight,
eye pain, fluids coming from the eye, double vision, redness,
or swelling of your eye or eyelid.
Common
Eye Complaints
Presbyopia
(prez-bee-OH-pee-uh) is a slow loss of ability to see close objects
or small print. It is a normal process that happens over a lifetime.
You may not notice any change until after the age of 40. People
with presbyopia often hold reading materials at arms length.
Some get headaches or "tired eyes" while reading or
doing other close work. Presbyopia is often corrected with reading
glasses.
Floaters
are tiny spots or specks that float across the field of vision.
Most people notice them in well-lit rooms or outdoors on a bright
day. Floaters often are normal, but sometimes they warn of eye
problems such as retinal detachment, especially if they happen
with light flashes. If you notice a sudden change in the type
or number of spots or flashes, see your eye doctor.
Dry
eyes happen when tear glands dont make enough tears
or make poor quality tears. Dry tears can be uncomfortable, causing
itching, burning, or even some loss of vision. Your eye doctor
may suggest using a humidifier in the home or special eye drops
("artificial tears"). Surgery may be needed for more
serious cases of dry eyes.
Tearing,
or having too many tears, can come from being sensitive to light,
wind, or temperature changes. Protecting your eyes (by wearing
sunglasses, for instance) sometimes solves the problem. Tearing
may also mean that you have a more serious problem, such as an
eye infection or a blocked tear duct. Your eye doctor can treat
or correct both of these conditions.
Eye
Diseases and Disorders Common in Older People
Cataracts
are cloudy areas in part or all of the eye lens. The lens is usually
clear and lets light through. Cataracts keep light from easily
passing through the lens, and this causes loss of eyesight. Cataracts
often form slowly and cause no pain, redness, or tearing in the
eye. Some stay small and dont change eyesight very much.
If a cataract becomes large or thick, it usually can be removed
by surgery.
During
surgery, the doctor takes off the clouded lens and, in most cases,
puts in a clear, plastic lens. Cataract surgery is very safe.
It is one of the most common surgeries done in the United States.
Glaucoma
results from too much fluid pressure inside the eye. It can lead
to vision loss and blindness. The cause of glaucoma is unknown.
If treated early, glaucoma often can be controlled and blindness
prevented. To find glaucoma, the eye doctor will look at your
eyes through dilated pupils. Treatment may be prescription eye
drops, oral medications, or surgery. Most people with glaucoma
have no early symptoms or pain from increased pressure.
Retinal
disorders are a leading cause of blindness in the United States.
The retina is a thin lining on the back of the eye. It is made
up of cells that get visual images and pass them on to the brain.
Retinal disorders include age-related macular degeneration,
diabetic retinopathy, and retinal detachment.
- Age-related
macular degeneration. The macula is part of the eye with
millions of cells that are sensitive to light. The macula makes
vision possible from the center part of the eye. Over time,
age-related macular degeneration can ruin sharp vision needed
to see objects clearly and to do common tasks like driving and
reading. In some cases, it can be treated with lasers.
- Diabetic
retinopathy. This disorder can result from diabetes. It
happens when small blood vessels stop feeding the retina properly.
In the early stages, the blood vessels may leak fluid, which
distorts sight. In the later stages, new vessels may grow and
send blood into the center of the eye, causing serious vision
loss. In most cases, laser treatment can prevent blindness.
It is very important that people with diabetes have an eye exam
through dilated pupils every year.
- Retinal
detachment. This happens when the inner and outer layers
of the retina become separated. With surgery or laser treatment,
doctors often can reattach the retina and bring back all or
part of your eyesight.
Conjunctivitis
happens when the tissue that lines the eyelids and covers the
cornea becomes inflamed. It can cause itching, burning, tearing,
or a feeling of something in the eye. Conjunctivitis can be caused
by infection or allergies.
Corneal
diseases and conditions can cause redness, watery eyes, pain,
reduced vision, or a halo effect. The cornea is the clear, dome-shaped
"window" at the front of the eye. It helps to focus
light that enters the eye. Disease, infection, injury, toxic agents,
and other things can damage the cornea. Treatments include changing
the eyeglass prescription, eye drops, or surgery.
Corneal
transplantation is used to restore eyesight when the cornea has
been hurt by injury or disease. An eye surgeon replaces the scarred
cornea with a healthy cornea donated from another person. Corneal
transplantation is a common treatment that is safe and successful.
The doctor may prescribe eyeglasses or contact lenses after surgery.
Eyelid
problems can come from different diseases or conditions. The
eyelids protect the eye, distribute tears, and limit the amount
of light entering the eye. Pain, itching, tearing and sensitivity
to light are common eyelid symptoms. Other problems may include
drooping eyelids (ptosis), blinking spasms (blepharospasm), or
inflamed outer edges of the eyelids near the eyelashes (blepharitis).
Eyelid problems often can be treated with medication or surgery.
Temporal
arteritis causes the arteries in the temple area of the forehead
to become swollen. It can begin with a severe headache, pain when
chewing, and tenderness in the temple area. It may be followed
in a few weeks by sudden vision loss. Other symptoms can include
shaking, weight loss, and low-grade fever. Scientists dont
know the cause of temporal arteritis, but they think it may be
a disorder of the immune system. Early treatment with medication
can help prevent vision loss in one or both eyes.
Low
Vision Aids
Many
people with eyesight problems find low vision aids helpful. These
are special devices that are stronger than regular eyeglasses.
Low vision aids include telescopic glasses, lenses that filter
light, and magnifying glasses. Also, there are some useful electronic
devices that you can either hold in your hand or put directly
on your reading material. People with only partial sight often
make surprising improvements using these aids.
