Yearly Eye Health Exams
Why do we have annual eye exam recalls? Why not every 2 or 3 years? It has long been the Beartooth Vision Center policy to remind our patients to come in for their eye examinations on a yearly schedule. We do this to ensure that our patient’s eyes are healthy, as many significant eye conditions have no symptoms. Because a poor fitting contact lens can be sight-threatening and because we want our patients to be aware of the newest lens technology, we also see our contact lens patients each year. After their annual eye exam the vast majority of all of our patients see better – sometimes much better – with their updated glasses and contact lens prescriptions. We believe it is important that our patients have the opportunity to improve their visual clarity once a year. It can change your life. Wouldn’t it be nice to have the option to hear better, to improve your sense of taste or smell, or to heighten your sense of touch once a year? It is truly wonderful that it is possible to do this so easily with your sight – and all it takes is scheduling an annual eye examination.
While a comprehensive yearly adult eye and vision examination may include the following tests, individual patient signs and symptoms, along with the professional judgment of Dr. Currence, may significantly influence the testing done.
The patient history helps to determine any symptoms the patient is experiencing, the presence of any general health problems, medications taken and occupational and environmental conditions that may be affecting vision. Dr. Currence will ask about any eye or vision problems you may be having and about your overall health. He will also ask about any previous eye or health conditions for you and your family members.
Depending on the results of the annual eye examination, additional testing may be required. The doctor will discuss with you the nature of any visual or eye health problems found and explain available treatment options. In some cases, referral for consultation or treatment by an eye specialist may be indicated, but this is rare. With the instruments we have in our office, many eye conditions can be treated and monitored here at Beartooth Vision Center.
If you have questions regarding any eye or vision conditions diagnosed, or treatment recommended, don’t hesitate to ask Dr. Currence. He is glad to help you to understand the status of your eyes and vision and why we do what we do in an eye examination.
Snellen acuity charts are used to measure the sharpness of your vision. Visual acuity measurements evaluate how clearly each eye is seeing. As part of the testing, you are asked to read letters on distance and near reading charts. In the world of visual acuity, the smaller the better. The results of visual acuity testing are written as ratios such as 20/40. For distance vision, the top number in the fraction is the standard twenty foot test distance. The bottom number is the smallest letter size you were able to read at the test distance. In an exam room a bit shorter than 20 feet, the chart letter sizes are calibrated and adjusted for the exam room length. A person with 20/40 visual acuity would have to get within 20 feet of a letter that can be seen at 40 feet by a person with 20/20 vision. A person with 20/20 vision can see at 400 feet what a 20/400 seeing person can only see when they are 20 feet away. In other words, the 20/20 person sees things clearly 1/20 the size of the 20/400 person. They aren’t 20 times better as a person, but they do see 20 times better. Sometimes life ain’t fair.
This testing is usually done without the use of eye drops. This allows the eyes to respond under normal seeing conditions and gives the most accurate glasses prescription. In some cases, however, such as for younger or non-verbal patients, or when some of the eye’s focusing power may be hidden or influencing the accuracy of the glasses prescription, eye drops are used. The drops temporarily keep the eyes from changing focus while the refraction is being done.
The health of the rear portion of the inside of the eye, including the retina, the optic nerve, the macula, and the retinal blood vessels are all evaluated using the Optomap Retinal Exam or with dilating drops with hand held lenses, or sometimes both. The Optomap takes a 200 degree panoramic digital laser scan of the internal eye in 1/4 second without dilation. In addition to the digital perspective it offers, the Optomap provides a powerful tool for comparison of retinal structure changes over the years – far better than old style hand written record notes. For these reasons, we highly recommend the Optomap for all of our patients for their eye exams each year. In this case, a digital picture truly has more value than a thousand words.
