Abstract
Systems, devices, and methods for electrophysiological recording from the eye are disclosed herein. An electroretinography device can detect a biopotential signal from an eye of a subject and transmit the same to a processor. Embodiments of the present technology include one or more features directed to improving the use and operability of an electroretinography device. For example, the device can include a proximal inner surface having a recess feature for removing or receiving fluids trapped between the device and the eye. The recess feature can include one or more grooves, channels or textured surface designed to collect and direct fluids away from the space between the device and the eye. The number, shape, size, position, orientation, and other features of the grooves and channels can be varied.
