To compare the Diopsys NOVA and LKC RETeval Devices using the Diopsys Lid Electrodes and LKC RETeval Self-Adhering Electrode Arrays.
This study is an open label, prospective study comparing the Diopsys NOVA and LKC RETeval devices using the Diopsys Lid Electrodes and the LKC RETeval Self-Adhering Electrode Arrays.
Subjects will receive the PhNR test three times using the Diopsys device and Diopsys Electrodes. Next, subjects will receive the FL Flicker test three times using the Diopsys device and Diopsys Electrodes. There will be a short break (10 to 15 minutes), then subjects will receive the PhNR test three times using the Diopsys device with LKC Electrode Arrays, followed by the FL Flicker test three times using the Diopsys device with the LKC electrode arrays. Subjects will receive another short break (5 to 10 minutes), then receive the PhNR test three times using the LKC device with the LKC electrode arrays, followed by the FL Flicker test three times using the LKC device with the LKC electrode arrays.
