Vision Exams

Eye Exam Image

At Precision Family Eyecare, we strive to provide comprehensive, primary eye care for the whole family. Preventative and routine eye exams are important to maintaining good eye health. Often, eye and vision problems do not have obvious symptoms or signs, but are easily diagnosed by a licensed optometrist. By diagnosing eye and vision conditions early on, our optometrist is able provide treatment options and in many cases restore or prevent vision loss. The American Optometric Association recommends yearly eye and vision exams, depending on whether you are at-risk or not.

Eye Exam and Consultation

During an eye exam, Dr. Nathan Dieckow will ask you questions about any symptoms or issues you are experiencing, medications your are currently taking, any blurry vision, your work environment, and your overall health. Family history and previous eye or vision conditions will also be discussed during this part of the examination. Dr. Dieckow will consider this information when determining any treatments or recommendations.

Vision Testing

Regular vision testing and evaluations ensure that you always have the clearest vision possible. Our Galesburg optometrist provides regular vision acuity test as part of a comprehensive eye exam. Dr. Dieckow will measure how each eye is seeing by using a digital acuity eye chart and a reading eye chart. The results of these tests are portrayed as a fraction, with 20/20 being the standard for normal distance and reading vision. Depending on the results of your vision test, Dr. Dieckow may prescribe corrective glasses, contact lenses, recommend lasik or other refractive surgical correction or recommend eye exercises and vision therapy treatment program. 

Eye Function Testing

In addition to vision testing, an eye exam in our Galesburg office includes testing eye functionality. Our optometrist performs several tests to evaluate depth perception, color vision, eye muscle capabilities, peripheral vision, and responsiveness to light. 

Autorefraction and Keratometry: This test helps to register an estimated baseline of what your prescription might be if you need one. It is noninvasive and takes just a couple of seconds. The technology is based on the retinoscopy reflex that reflects off of your retina in the back of your eye. 

Several other simple tests are completed to determine whether the eyes are focusing, moving, and working together properly. The test results enable the doctor to diagnose any underlying conditions that may be impairing the eyes ability to focus or work together.

Eye Health

As part of a comprehensive eye exam, our Galesburg optometrist examines the overall health of the eye through a visual examination and tonometry. Your optometrist evaluates eye health by visually inspecting the eye and eyelids using magnification and a bright light. To examine the internal structures of the eye, we may dilate the pupils. Increased eye pressure may be an indicator of glaucoma, so we utilize tonometry to measure eye pressure. 

Other medical tests Performed at Precision Family Eyecare include:

Digital Fundus Photography: This test documents posterior structures of the eye important for proper vision and eye health, and is helpful in assessing and monitoring for multiple eye pathologies. 

GDX: This test utilizes scanning laser polarimetry to evaluate the retinal nerve fibre layer which is an anatomically clear layer of the retina, and is important in monitoring and managing glaucoma a leading cause of blindness.

OCT: This test is a noninvasive test that utilizes light waves to image cross section pictures of your retina. It has multiple applications in diagnosing and monitoring several eye pathologies that Dr. Dieckow is trained to manage including: glaucoma, macular degeneration, and diabetic retinopathy. 

Visual Fields: This test utilizes a test stimulus to map out your field of vision. It often takes a couple of minutes per eye. We find for chronic conditions it is best to reappoint to a different day than your comprehensive annual eye exam so that patients are able to focus on the test stimulus without visual fatigue in order to yield optimal test results. This test also has multiple applications as most eye pathologies are associated with characteristic field of vision loss. 

After completing these tests, Dr. Dieckow reviews the results and discusses any treatments with you. Contact us at (309) 343-1107 today to schedule a comprehensive eye exam.
