Abstract
Devices and method for determining a pupil size of a subject having closed eyelids.
Claims19
A device for pupil size and/or pupillary reflex assessment in a subject having closed eyelids, the device comprising:
- a non-inductive light source configured to transmit light to a vitreous cavity of a subject;
- and
- a first light detector configured to detect a portion of the transmitted light exiting a first pupil of the subject through a closed eyelid;
- a second light detector configured to detect a portion of the transmitted light exiting a second pupil of the subject through a closed eyelid;
- wherein the non-inductive light source is configured to transmit light having a wavelength in a range of 750 nm-1400 nm.
A method for determining pupil size of a subject having closed eyelids, the method comprising:
- transmitting light having a wavelength in a range of 750 nm-1400 nm toward a vitreous cavity via a temple or a back of the subject's head, using one or more light sources;
- detecting, using one or more light detectors, a portion of the transmitted light exiting the subject's pupil through the subject's closed eye.
A platform unit configured to be worn and/or positioned on the subject's head, such that at least part of said platform unit is positioned in front of the subject's eyes;
- wherein said platform unit comprises one or more non-inductive light sources positioned to transmit light to a vitreous cavity of the subject, and one or more light detectors;
- wherein said platform unit is sized and shaped to prevent penetration of light;
- wherein said non-inductive light source is configured to transmit light having a wavelength in a range of 750 nm-1400 nm.
