[/vc_column_text][vc_column_text]Multifocal ERG is a highly-advanced vision test that objectively measures how well your vision system is working. Information from this test will help your doctor diagnose various vision disorders, as well as better understand when changes in your visual function occur.[/vc_column_text][vc_column_text]
What is a multifocal electroretinography vision test?
The Diopsys® mfERG vision test is a painless, safe, non-invasive way for your eye care provider to objectively measure the function of your retina – the light-sensitive layer at the back of your eye.
When light from an image enters your eye, it is turned into electrical energy by cells in the retina. Multifocal ERG uses visual stimuli from a computer screen to elicit electrical responses from different areas within the retina. The electrical energy created is measured by the Diopsys® mfERG vision test, and used to create a report for your doctor. It is similar to an EKG, but for your eyes.[/vc_column_text][vc_empty_space height=”15px”][vc_column_text]
How do I prepare for a multifocal ERG test?
Your face should be clean, dry, and free of any gels, sprays, oils, or lotion.[/vc_column_text][vc_empty_space height=”15px”][vc_column_text]
How is the Diopsys® mfERG vision test done?
A technician will dilate your eyes, clean and dry the skin under your eyes and on your forehead, and then place sensory pads on the recently cleansed areas.
Once the test begins, you will see white patterns that appear to flash quickly over and over again in different places on a computer screen. You will be asked to focus on the middle of the screen during the test. The computer will record your eyes’ response to the images and produce a report for your doctor.[/vc_column_text][/vc_column][vc_column width=”1/3″ el_class=”sidebar-dark”][vc_single_image image=”423″ img_size=”medium” alignment=”center” onclick=”custom_link” link=”http://info.diopsys.com/find-a-doctor”][vc_column_text]
