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.
Claims20
An electroretinography device comprising:
- an ocular portion configured to detect a biopotential signal from an eye of a subject, the ocular portion including:
- a proximal portion configured to be placed in contact with an anterior surface of the eye,
- a distal portion including at least one side wall, and
- a conductive element housed in the ocular 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.
