Diagnostic Testing
In the diagnosis and treatment of eye disease, the doctors at Grossnickle Eye Center use an extensive array of advanced technology.
 
Photography
Using our advanced digital imaging system, your doctor can use photography to study your retina or optic nerve. Results are available the day of the exam, so your doctor can review the findings and counsel you about your visual pathology. Photographic studies are routine for patients with a wide range of conditions, glaucoma, macular degeneration and diabetic retinopathy.
 
Scanning lasers
Grossnickle Eye Centers have laser scanners onsite that allow us to create three- dimensional maps of your eye to diagnose and track the progression of eye disease. They include:

Optical Coherence Tomography
OCT is an imaging device we employ in the diagnosis of glaucoma and retinal diseases. Utilizing a procedure known as optimal coherence tomography, OCT uses high-resolution scanning to image and analyze macular thickness, the retinal nerve fiber layer and the optic disc. The procedure is non-invasive; in fact, there is no contact with the eye. More information.

GDx
The GDx test examines the nerve fiber layer – the tissue directly affected by glaucoma – to determine the presence and extent of glaucoma damage.

The process takes only about three minutes, is non-invasive, and does not require dilation. Because of this, and because the results are fast and precise, it is a valuable and practical tool for testing all patients, not just those with clear symptoms of glaucoma. More information.

LASIK Wavefront Mapping
Traditionally, when people are measured for glasses, contacts or laser corrective surgery, we measure the average refraction of their entire eye. Using this measure, we are able to provide good vision outcomes.

But refraction actually varies across the surface of the eye, and to give patients the most precise vision possible, it should be measured at individual points.

Custom LASIK Wavefront mapping does exactly that, allowing the physician to take a detailed “fingerprint” of your eyes and accurately assess your unique visual profile.

With this information, together with standard vision-chart and other tests, your doctor can make subtle changes to your correction treatment that can produce an optimal result. More information.
