Comprehensive Eye Health Exam
Did you know that your eye doctor is often able to detect diseases simply by looking inside your eyes? Diseases such as diabetes, high blood pressure and even heart disease often show signs in the eyes first. An eye exam is so much more than simply evaluating vision for glasses or contacts. Your eyes are windows into your overall health. Your eye doctor will always address your vision needs and attempt to maximize your sight, but they will also perform tests to monitor your overall health to help you achieve the best health you can. Checking and monitoring for things like glaucoma, cataracts and macular degeneration are all part of your comprehensive eye health examination at Keylon Eye Care.
Comprehensive Eye Health Examination Q&A
- What is a Comprehensive Eye Examination?
- What should I expect as part of my comprehensive eye exam?
- Are vision-screening programs (ex: school screenings) adequate eye exams?
- When should you have a comprehensive eye exam?
During a comprehensive eye exam, your doctor will not only measure for your prescription, but will also check the health of all layers and levels of your eyes.
This allows eye doctors to detect and monitor problems and diseases that often times can go unnoticed if not specifically looked for.
A thorough patient history is a vital part of your visit to any doctor. It not only allows doctors to address any immediate problems you are experiencing, it also allows them to detect and screen for any potential problems you may be unaware of.
Patient history should include both the history of your eyes such as wearing glasses or injuries you may have had, and it should also include your medical history as well. Many systemic medical problems can first be detected by your eye doctor, so it is important that they have as much accurate information about you as they can.
Be sure to be very thorough and honest when you give your history to the doctor or staff because without a complete picture, it can be hard to pinpoint a precise diagnosis.
Patient history should be updated annually or anytime that there are any significant changes such as beginning or ending any medications.
Visual acuity allows your eye doctor to tell just how clearly you are able to see things.
Visual acuity is the part of an eye exam that most people are familiar with. It usually involves reading letters or symbols off of a chart. Your visual acuity result is usually given to you in a fraction such as 20/20 or 20/40.
The first number represents the testing distance, which is usually 20 feet. The second number represents the smallest letter size that you were able to read. Therefore, if your visual acuity is 20/20, you were able to see at 20 feet what a normal person can also see clearly at 20 feet. If your visual acuity is 20/40, you were able to see at 20 feet what a normal person can see clearly at 40 feet.
It is important to remember that a comprehensive eye health exam is a lot more than just a visual acuity number!
Every eye doctor has certain preliminary and screening tests that will be preformed at the start of your exam. These tests help to begin the process of finding potential problems you may be experiencing and they provide the doctor with valuable information for their diagnosis.
Some of the most common preliminary tests are depth perception tests, color vision tests, peripheral vision tests, pupil response tests, and muscle movement tests.
Refraction is the process of determining the appropriate lenses that are needed to give you optimal vision.
This is the part of the examination process that most people remember and sometimes stress about. Your doctor will use a large lens system called a phoropter to measure your prescription.
It is important that you are honest during this part of the examination. Often times, the numbers found through refraction are used to write your prescription.
It is also important that you are relaxed and well rested when you come in for this portion of your eye exam. Being nervous or tired can change the prescription results that your eye doctor finds. Just remember, there are no wrong answers during this part of your exam and your doctor wants to make sure you see the best you possibly can!
Eye Health Evaluation
This portion of the exam allows your eye doctor to examine all of the layers and tissues in your eyes. Sometimes eye drops are required for this portion of the exam because they can allow your eye doctor to see things that can be hidden.
Your doctor will use an instrument called a slit-lamp for this portion of the examination.
When your doctor finds a problem area, suspects a potential problem or needs additional information about your eye health, you may undergo supplemental testing.
Your eye doctor will always explain each procedure to you and discuss with you why they feel it is necessary for your comprehensive exam. If you have any apprehension or questions about any testing, be sure to ask your doctor.
Sometimes the supplemental testing can be done in the office the same day as your exam. Other times, for insurance reasons, it may be necessary for you to return to the clinic for your tests.
Often times the people conducting the vision screenings are volunteers or are not adequately trained eye care professionals.
Vision screenings are extremely limited on the amount and type of instruments and technology available at the screening site.
Passing a vision screening does not mean that you are free of vision or eye health problems. It is important that you still regularly see your eye doctor for a comprehensive exam.
