First Claim
Patent Images
1. An apparatus comprising:
- a power source;
a light source comprising an infrared light source and a visible light source, the light source being operatively connected to the power source;
an image sensor positioned adjacent to the light source along a first axis, wherein the light source is either inline or coaxial relative to the light source;
a lens positioned between the light source and the image sensor, inline relative to the image sensor along the first axis; and
a housing unit comprising the power source, the light source, the image sensor, or the lens, or any combination thereof, and further comprising an opening having an external-light blocking eyepiece, the opening being positioned adjacent to the light source opposite the lens and inline relative to the lens along the first axis.

17. An apparatus comprising:
-
a pair of light emitting devices configured to emit a light beam onto a pair of target eyes, the light beam comprising infrared light and visible light; one opening or a pair of openings configured to couple with the pair of target eyes to block light external to the apparatus from hitting the pair of target eyes; a pair of image sensors configured to capture light reflected from the pair of target eyes; and a pair of lenses configured to focus light reflected from the pair of target eyes onto the pair of image sensors. - View Dependent Claims (18)

19. A method for examining a pair of target eyes of a patient using an apparatus, the method comprising:
-
covering the pair of target eyes with one or a pair of external-light blocking eyepieces of the apparatus, the covering comprising positioning the pair of external-light blocking eyepieces in contact with the patient'"'"'s face; monitoring pupil dilation of the target pairs of eyes for a period of time while the pair of external-light blocking eyepieces are in contact with the patient'"'"'s face; and emitting, by a pair of light sources of the apparatus based on the monitoring, infrared light at the pair of target eyes; and detecting, using a pair of image sensors of the apparatus, infrared light reflected by the pair of target eyes in response to the emission of infrared light by the pair of light sources. - View Dependent Claims (20, 21, 22, 23, 24, 25)
