A Window Into The Visual Brain
Lange Eye Care and Associates announces the addition of the Diopsys® NOVA-VEP Vision Testing System to their practice. The new vision testing system helps eye care professionals detect vision defects, including glaucoma and other neuro-visual disorders.
Diopsys® NOVA-VEP Vision Assessment
The Diopsys® NOVA-VEP Vision Testing System is a painless, non-invasive vision test that objectively measures the function of the entireDiopsys® NOVA-VEP Vision Assessment visual pathway from the eyes to the visual center of the brain. The Diopsys® NOVA device does this by using a technology called Visual Evoked Potential (VEP).
VEP has been demonstrated to aid in the diagnosis and treatment of many disorders including amblyopia, brain injury, stroke, glaucoma, multiple sclerosis, and other vision-related issues.
The purpose of this series of tests is to provide comprehensive diagnostic information to better plan your treatment and monitor the results.
Visual Evoked Potential (VEP)
Visual evoked potential (VEP) directly measures the electrical activity in the vision system. When light from an image enters our eye, it is converted into electricity at the retina and travels through the optic nerve and other pathways to the part of our brain that processes vision, the visual cortex. brain – visual cortes. We will be measuring your visual cortex and how fast it gets there.
The VEP technology in the Diopsys® NOVA device helps us determine how your eyes communicate with your brain in a way that no other instrument or vision test can.
By using Visual Evoked Potential technology, we can measure the entire vision system, from the front of the eye to the visual cortex of the brain, without the patient having to say a word.
Preparing for Your VEP Test
It is best for hair to be clean, dry and free of any gels, sprays or oils as three sensory pads will be placed on your head.
For young children it may be helpful to bring a favorite item such as a blanket, pacifier, or toy to make them feel more comfortable during the test.
How the VEP Test is Done
After positioning three sensory pads on the head, a technician starts the test. You will see a series of black and white patterns that appear to “flip” quickly over and over again on a computer screen. It is simply a matter of looking at the pattern for 10 to 60 seconds for each recording. The entire testing time will vary depending on the tests the doctor has ordered. The technician may also choose to patch one eye at a time to record each eye’s response independently.
The doctor will review the profile of your eye-brain signals to help diagnose visual pathway disorders as well as to help determine how your treatment is progressing.
Should you have any questions about the Diopsys® NOVA-VEP Vision Testing System, or would like to make an appointment, please contact one of the Doctors at Lange Eye Care and Associates.
