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 features for (i) inhibiting multiple devices from adhering or sticking to one another or a different object and (ii) providing tactile feedback to users to help distinguish one side of the device from the other.
Claims22
An electroretinography device, comprising:
- an ocular member configured to detect a biopotential signal from an eye of a subject, the ocular member including:
- a proximal portion comprising a proximal outer surface extending radially inward along a distal direction, a proximal inner surface opposite the outer surface, and a proximal end surface extending between the proximal inner surface and the proximal outer surface, wherein, when the ocular member is disposed over the eye, the proximal inner surface is disposed over an anterior surface of the eye and the proximal outer surface is positioned adjacent an eyelid of the subject;
- and
- a distal portion coupled to the proximal portion, wherein the distal portion comprises a distal outer surface extending radially outward in the distal direction, a distal inner surface opposite the distal outer surface and defining a distal recess, and a distal end surface extending between the distal inner surface and the distal outer surface,
- wherein at least one of the proximal portion or the distal portion includes an interface feature configured to decrease contact area with another object;
- a conductive element in an annular channel of the proximal portion;
- and
- a signal relay operatively connected to the conductive element and configured to transmit the biopotential signal from the conductive element to a signal processor.
An electroretinography device, comprising:
- a proximal portion comprising a proximal outer surface extending radially inward along a distal direction, a proximal inner surface opposite the outer surface, and a proximal end surface extending between the proximal inner surface and the proximal outer surface, wherein, when the proximal portion is disposed over an eye of subject, the proximal inner surface is disposed over an anterior surface of the eye and the proximal outer surface is positioned adjacent an eyelid of the subject;
- and
- a distal portion coupled to the proximal portion, wherein the distal portion comprises a distal outer surface, a distal inner surface opposite the distal outer surface and defining a distal recess, and a distal end surface extending between the distal inner surface and the distal outer surface, wherein the distal portion includes an interface feature configured to decrease contact area with another object adjacent to the distal portion.
