Before
your exam we will run a series of
tests to check the general health of your eyes. Using specialized
instruments to gather important data, we will measure the power of your eye to focus at distance, the pressures
inside your eye (glaucoma screening), curvature of your eye,
prescription in your old glasses (if applicable), and your field of
vision (peripheral vision).
Once
you are in the exam room, we
will take a detailed medical history. Many health conditions and medicines may affect your
eyes; therefore, it is important that we understand your general health
and are aware of medicines you take, including vitamins, herbal
supplements, tobacco, alcohol or other substances. This is especially
important if we need to prescribe any medications for eye related
conditions so there are no adverse reactions. Past injuries to the head
or eye itself are important in understanding your visual performance, as
well as the work, school, hobbies and recreational activities you enjoy.
Understanding your visual needs allows us to better evaluate your vision
and make
recommendations to enhance your quality of life.
Finally,
we will run a preliminary check on how clearly you are seeing
using the familiar eye chart. Once this is done, Dr. Hart will review
all the data and continue the exam.
Eye
Health Testing
One
very important part of your annual eye exam is to ensure that
your eyes are healthy and free of disease. Besides the information
gathered earlier, Dr. Hart uses several instruments to help
him determine the state of your eyes' health. The
slit-lamp is a high-powered microscope designed to give him a very close
look at your cornea, iris, lens and eyelids. An ophthalmascope
allows Dr. Hart to shine a bright light into your eyes to look at your optic nerve and the surrounding tissues.
Routine dilated examinations are an important and
painless part of your annual visit. The pupil of the eye is like a
window. Dilating the pupils allows the doctor to see the entire back of
the eye to make sure it is healthy. Most eye diseases do not have
painful or noticeable symptoms until it is too late. Early detection of
serious eye diseases can prevent sight loss. Your eyes are completely
evaluated inside and out for not only eye disease, but other health
problems that affect the eyes. The following is an example of visual and
health problems that can be detected with a routine dilation:
|
Cataracts
|
High Cholesterol
|
|
Glaucoma
|
Hyperthyroidism
|
|
Macular Degeneration
|
Hypertension
|
|
Retinal Disease
|
Diabetes
|
|
Retinal Detachments
|
Multiple Sclerosis
|
Visual
Acuity Testing
During
the exam Dr. Hart will check your visual acuities, or sharpness of
vision, to assess how well you are seeing. Did you know that vision is a dynamic process?
Your
vision is constantly changing, and the questions we ask and our testing help
Dr. Hart to understand how your vision is
throughout the day.
Dr.
Hart will test your near and distance vision to determine the
correct amount of lens power you may need for best clarity of sight and comfort.
This is done using an instrument
called a phoropter, a large lens and prism bank used to subjectively
measure the power of your eyes to see clearly (refraction). At the
conclusion of this procedure Dr. Hart will know the prescription power
you need for glasses, as well as the contact lens prescription if you
wear contacts.
All
the information that has been gathered during the exam helps Dr. Hart
make some important decisions about your vision. Obviously, if you
are nearsighted or farsighted or have an astigmatism, he will prescribe
glasses or contacts to help you see clearly. Sometimes
lenses may be prescribed to prevent further problems down the
road. For instance, he may prescribe a stress relieving lenses to a
child for nearwork when they are young to help prevent nearsightedness
when they get older. Other times he may prescribe an occupational lens to
a patient who experiences fatigue and eyestrain from working on the
computer all day.
Vision Performance Evaluation -
Going beyond 20/20
Because it is our goal to eliminate
all visual obstacles, we routinely
provide an expanded assessment of eye tracking, focusing and teaming
skills to determine if your visual system is working as efficiently as
it should be. We will check to see if your eyes aim, move and work as a coordinated
team, if they maintain clear vision at varying distances, and if you can
accurately control your eye movements. Eighty percent of what we learn comes through the visual
system. Problems with poor visual skills can affect ones performance in
school, work, or play. Visual deficiencies may cause an individual to
slow down, be less accurate, experience excessive fatigue, or make
errors. Symptoms of headaches, eyestrain, miscopying, frequent loss of
place, difficulty sustaining attention, and blurred or double vision
relate directly to deficient visual skills of tracking, focusing or eye
teaming.
We
can also evaluate visual information processing skills that allow us to
perform at our full potential. If patients have poor visual skills
and exhibit symptoms that indicate their visual system is hindering
their performance or affecting their behavior, we will recommend a full
diagnostic assessment (sensory-motor and neurobehavioral status exams)
to identify low areas in visual information processing. We will
assess strengths and weakness as they relate to visual-motor
integration, visual memory, visual figure ground, vision discrimination,
visual closure, directionality, laterality, bilateral integration,
language automaticity, letter reversals, reading, handwriting, visual
attention, and
visual endurance. These information processing skills are necessary to
succeed in any learning or work environment, and these tests help us
make decisions about treatment. We also work closely with other professionals such as
occupational therapists, psychologists, teachers, audiologists, speech and language pathologists,
and medical professionals in providing a
multi-disciplinary approach to your care.
Eye Exams are Recommended Yearly
Many
sight-threatening eye diseases are very treatable if they are caught
early, so it is critical that these tests are run every year. Just like seeing the dentist, it is better to visit your
eye doctor BEFORE something is seriously wrong, so that risk factors can
be identified, small problems managed, and bigger problems avoided.
Many
eye diseases are silent threats to your vision with no obvious symptoms
until it is too late. The only way to detect them is regular eye exams.
Our goal at Visionhealth is to not only provide our patients with
the clearest sight possible but also to ensure that you have a healthy
visual system that will last a lifetime.
If you have not had a recent eye exam or if you are looking for a
practice that is committed to providing the very best in vision care,
then we invite you to call our office to schedule an examination.
We are here to help!
