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.

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 features for (i) improving the quality of light stimulus delivered to the eye or (ii) providing a better fit around the eye or a contact lens worn on the eye. These features can account for anatomical differences between different subjects by either masking or accommodating such differences.

Abstract

The present disclosure provides electroretinography devices configured to detect biopotential signals from an eye of a subject. In some embodiments, the device is configured to prevent the subject's eyelids from closing over the device when placed in contact with the anterior surface of the subject's eye. In some embodiments, the device has a Young's modulus of no more than about 50 MPa. In some embodiments, the device includes a diffusing or refracting element configured to scatter, focus or diverge incident light. In other embodiments, the device includes a void through which incident light can enter the subject's eye without passing through any portion of the device.
