Dr. Galbrecht Answers Questions About the Zeiss GDx

eye exam shawneeQ: Please describe what the GDx is used for and give a basic sense of how it works.

Dr. Galbrecht: The GDx is used to measure the optic nerve digitally in order to diagnose and manage glaucoma. It is a confocal polarimetric scanning laser ophthalmoscope that is intended for imaging and three-dimensional analysis of the fundus and retinal nerve fiber layer (RNFL), the back portion of the eye.

Q: What are the diagnostic benefits of scanning laser polarimetry that distinguish it from other scanning techniques?

Dr. Galbrecht: The GDx Normative Databases aid in the diagnosis and monitoring of diseases and disorders of the eye that may cause changes in the polarimetric retinal nerve fiber layer thickness, the part of the eye where subtle changes can occur.

Q: What types of eye diseases and disorders is this analysis significant for?

Dr. Galbrecht: The GDx is to be used in patients who may have an optic neuropath, have been diagnosed with glaucoma, or are considered to be suspected of having glaucoma.

Q: What is it about this particular instrument that you find most exciting; the component that made you feel you need to invest in this for your practice?

Dr. Galbrecht: The most exciting component is the ability to compare results from previous visits to current visits to notice and document small changes in order to manage and treat the patient better.

Q: Can you describe the patient experience when you use the GDx?

Dr. Galbrecht: The patient will be looking at a blinking light while the machine scans the fundus one eye at a time. It will take two scans per eye and take about 10 minutes to complete the test.

Q: Do your patients appreciate the upgrade in equipment and technology?

Dr. Galbrecht: Patients with glaucoma like this test because they can see if there are changes from one visit to the next. This shows the patient that their current medication regimen is working or is not working.

Q: How does this new instrument improve glaucoma screening?

Dr. Galbrecht: Before this instrument, there was no way of digitally scanning the fundus to look for subtle changes. The doctor relied on the patient’s symptoms and other test results to decide if the current treatment regimen is working.

Q: For which patients do you use the GDx? Is it for patients with specific concerns or symptoms?

Dr. Galbrecht: The GDx is used for specific patients, mostly those who have been diagnosed or suspected of glaucoma or an optic neuropathy.

Q: Can you share a particular story in which you were able to help a patient in a special way by using this equipment?

Dr. Galbrecht: A glaucoma patient is scanned once a year and these results are used many times to determine the course of future treatment. This test gives the patients the security of how their disease is progressing.

Q: Why did you choose this supplier to purchase this particular equipment?

Dr. Galbrecht: This technology was the best available for this particular condition.
