St. Charles Vision now offers a new all-automated eye exam that takes only minutes but provides results not possible with traditional exams.
It starts with an OPD-Scan II, which measures the prescription for each eye and provides images of the topography of the cornea, which is especially beneficial for patients who wear contact lenses. That is followed by the Optomap, a retinal eye exam that takes an image of the back of the eye but does not require dilation of the pupil. Information from the scans is electronically recorded in the patient's medical record and is used with an automated Total Refraction System to determine the correct prescription for distance vision and reading.
The Gdx test, also available at St. Charles Vision, can detect signs of glaucoma as much as seven years before the patient begins to lose vision. The test uses a laser to detect the thickness of the nerve fiber layer instead of simply measuring eye pressure as traditional glaucoma tests do. The Zeiss Ocular Coherence Tomography Nerve Fiber Analyzer exam provides 3-D cross-sectional images of the retina, which help doctors monitor vision-impairing diseases such as macular degeneration and glaucoma.
