Diopsys® Light Induced Visual-response (LIV)™ tests are painless, non-invasive, and provide your doctor with comprehensive information on the function of your vision.
Like an electrocardiogram (EKG) which tests heart function, LIV tests work by evaluating how the cells within your vision system are functioning. Eye disease disrupts that function as cells become unhealthy. By catching this dysfunction before the cells die, your doctor may be able to prescribe treatment to make the cells healthy again. Additionally, your doctor can use the tests to help determine if your treatment is working.
Visual electrophysiology, including electroretinography (ERG) and visual evoked potential (VEP), is the technology behind Diopsys® Vision Testing Systems. The different ERG and VEP test results assist in better planning your treatment (if any) and monitoring your visual function.
