Comprehensive Eye Exam

Comprehensive Eye Exam at Groetken Family Eye Care

A comprehensive examination is a detailed and complete evaluation of the health of each area of the eye as well as thorough vision testing and prescription assessment.

Our doctor and highly trained staff explain the purpose of each test as it is performed. We want to help you understand all your eye health and vision treatment options. During the exam, pressure in the eye is measured using Contact Tonometry which is significantly more accurate than the “poof of air” used to measure pressure in the past. This test is used along with other tests to determine if you have or are at risk of developing glaucoma. In addition, the back of the eye, including the retina, macula, and ocular nerve are examined for signs of disease and problems not limited to, macular degeneration, diabetic retinopathy, and retinal holes/tears or detachments. Observation of the back of the eye is performed by dilation of the pupils. The doctor performs refractive testing to determine the optical lens strength required for the clearest possible vision. Binocular vision skills are tested as well; this is to ensure that the eyes work together properly as a unit. These skills include depth perception, eye muscle coordination and the ability to change focus from near to far objects. Pupil responses are tested, and the cornea and lens are checked for general health and the possible development of cataracts and other eye health issues.

It is important to have a comprehensive eye exam every 12 months.

Getting your prescription checked by your doctor is the best way to keep your eyewear current and your eyes in good health. Eye diseases such as glaucoma display no symptoms until full onset has occurred; this is a disease that can be prevented through early detection and maintenance. In addition, prescription changes do not necessarily reveal themselves through secondary symptoms. Changes in the amount of myopia (near-sightedness) or hyperopia (far-sightedness) occurring can be masked by the eye muscles straining to accommodate for the change.  Schedule a comprehensive eye exam online today!

Optomap Retinal Imaging

Annual eye exams are vital to maintaining your vision and overall health. Groetken Family Eye Care offers the optomap® as an important part of our eye exams. The optomap produces an image that is unique and provides Dr. Groetken with a high-resolution 200° image in order to ascertain the health of your retina. This is much wider
than a traditional 45° image. Many eye problems can develop without you knowing, in fact, you may not even
notice any change in your sight – fortunately, diseases or damage such as macular degeneration, glaucoma,
retinal tears or detachments, and other health problems such as diabetes and high blood pressure can be seen
with a thorough exam of the retina.
The inclusion of optomapas part of a comprehensive eye exam provides:
• A scan to show a healthy eye or detect disease.
• A view of the retina, giving Dr. Groetken a more comprehensive view than they can get by other means.
• The opportunity for you to view and discuss the optomap image of your eye with Dr. Groetken at the
time of your exam.
• A permanent record for your file, which allows Dr. Groetken to view your images each year to look
for changes.
The optomap is fast, easy, and comfortable for anyone. The entire image process consists of you looking into the
device one eye at a time. The optomap images are shown immediately on a computer screen so we can review it
with you.

Specialized Medical Eye Testing

We recommend and perform various types of medical eye testing as necessary. The tests we perform include industry standard Humphrey Automated Visual Field Testing, , OCT (Optical Coherance Tomography), Pachymetry, Schirmer’s test (for dry eye), color testing, and depth perception.

A visual field test measures the effectiveness of a patient’s peripheral vision. This test is used primarily for glaucoma suspects or for patients that have been diagnosed with glaucoma. It is also useful to determine if there is any evidence of stroke or tumor affecting the optic nerve.

The OCT is an instrument used for measuring the thickness of the optic nerve fibers which become thinner with glaucoma. It is also useful in measuring the thickness of the macula, which in turn aids in diagnosis of various issues such as macular degeneration, macular edema (especially in diabetics or after cataract surgery).

Pachymetry determines the thickness of the cornea. This is especially useful in diagnosis and treatment of glaucoma, as well as LASIK evaluations,and evaluating corneal swelling.

Shirmer’s testing determines tear production to determine if the patient has dry eye syndrome.

Color testing determines a patient’s level of color sensitivity and discernment.  Schedule your next appointment online today!
