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.
Claims12
An ocular device configured to detect one or more biopotential signals from a patient, the ocular device comprising:
- an ocular region configured to be placed in contact with an anterior surface of an eye, wherein the ocular region is monolithic such that a continuous surface extends along an entirety of the ocular region, the ocular region comprising—
- a distal portion including an outermost sidewall;
- and
- a proximal portion coupled to the distal portion and including a flange region extending from the sidewall of the distal portion in a radially outward direction, the flange region including (i) an inner surface that is a proximal-most surface of the ocular region and (ii) an outer surface configured to abut an eyelid of the patient when the device is disposed over the eye;
- and
- a void between the outermost sidewall of the distal portion, wherein the void extends (i) across the ocular region and (ii) through the proximal portion and the distal portion,
- wherein:
- the inner surface includes (i) a first region extending laterally inward and partially distally, and (ii) a second region, laterally inward of the first region, extending laterally inward and partially distally further, and
- when the device is disposed over the eye, the first region is positioned over a portion of a sclera of the patient and the second region is positioned over a portion of the cornea of the patient;
- and
- a conductor disposed within the ocular region and configured to be operatively connected to a signal relay.
