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.
Claims24
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 and comprises—
- a distal portion including an outermost sidewall and a distalmost edge defining a plane extending laterally across the ocular region;
- a distal surface extending across at least a portion of the ocular region, wherein the distal surface is proximal to the plane defined by the distalmost edge, and wherein the distal surface is convex and extends between outer regions of the ocular region;
- 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 an outer surface configured to abut an eyelid of the patient when the device is disposed over the eye;
- and
- a conductor disposed within the ocular region and configured to be operatively connected to a signal relay.
An electroretinography device, comprising:
- an ocular region comprising—
- a first portion including an outermost sidewall and a distalmost surface defining a plane;
- a second portion positioned radially inward of the sidewall and extending across the ocular region, the second portion including a generally convex distal surface that is proximal to the plane defined by the first portion;
- and
- a third portion proximal to the first portion and the second portion, the third portion including a flange region extending from the sidewall of the first portion in a radially outward direction, the flange region including an inner surface and an outer surface each of which is curved such that, when the device is disposed over the eye, the outer surface abuts an eyelid of the eye and the inner surface abuts a sclera of the eye;
- and
- a conductor disposed within the ocular region and configured to be operatively connected to a signal relay.
An electroretinography device, comprising:
- a first portion including an outermost sidewall and a distalmost surface defining a plane;
- a second portion positioned radially inward of the sidewall, the second portion including a convex distal surface that is proximal to the plane defined by the first portion;
- and
- a third portion proximal to the first portion and including a flange region extending from the sidewall of the first portion in a radially outward direction, the flange region including inner and outer surfaces each of which is curved such that, when the device is disposed over the eye, the outer surface abuts an eyelid of the eye and the inner surface covers an anterior surface of the eye,
- wherein the first portion, the second portion, and the third portion are formed of a single material.
