Diopsys ERG and VEP Vision Testing Systems
Beginning this May we will be introducing our new Diopsys ERG and VEP Vision Testing Systems at our Kirkland location. This machine will change the way we are able to diagnose allowing our doctors to collect more pieces of the puzzle. Diopsys is the leader in providing ophthalmologists and optometrists with objective, functional information about the vision system to aid in the early detection of vision disorders and patient management through ERG and VEP vision testing. Not only are we able to use this piece of equipment for our vision therapy patient but in fact we are able to monitor back of the eye diseases and catch warning signs much much sooner! Technology is becoming so incredibly advanced and we are excited to have the ability to offer this test to our patients as we highly believe in preventative medicine.
What is the Technology?
The Diopsys ERG tests use electroretinography (ERG) technology to help eye care specialists gain objective, functional information about the performance of the inner retinal cells of the eye, especially in the macula.
Electroretinography measures the electrical responses of various cell types in the retina, including the photoreceptors (rods and cones), inner retinal cells (bipolar and amacrine cells), and the ganglion cells. Electrodes are usually placed on the cornea and the skin near the eye, although it is possible to record the ERG from skin electrodes.
Diopsys® VEP tests use a technology called Visual Evoked Potential (VEP) to objectively measure the functional responses of the entire visual pathway from the anterior segment of the eye to the visual cortex.
Evoked potential (EP) tests measure the electrical activity of the brain in response to stimulation of specific sensory nerve pathways. They are able to detect the slowing of electrical conduction caused by damage along these pathways even when the change is too subtle to be noticed by the person or to show up on neurologic examination. During a Visual Evoked Potentials (VEP) test the patient sits before a screen on which an alternating checkerboard pattern is displayed.
What Does This Mean For Me?
For referring providers we are one of few in the area that have this technology and are currently offering the ability to co-manage patients to have this test preformed. We will begin office training the beginning of May followed by in office testing and full testing will begin mid-May.
For current and prospected patients please feel free to contact our office at any time to receive more information. We will being testing our patients with current medical diagnoses and risk factors as soon as we are up and running mid-May. If you believe you are at risk for any vision problems or diseases please begin by scheduling an eye health evaluation where we can check all faucets of your vision and eye health.
