Abstract
An ophthalmic device having a single or dual compartment configuration selectively emits infrared and visible light beams onto one or a pair of target eyes. The device performs eye fundus imaging and aids in the detection of ailments as indicated by anomalies in the pupillary reflex.
Claims18
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 image sensor;
- 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.

An apparatus comprising a housing unit, the housing unit comprising a first compartment and a second compartment operatively connected to one or more power sources, each of the first compartment and the second compartment comprising:
- a light source comprising an infrared light source and a visible light source, the light source being operatively connected a 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 image sensor;
- a lens positioned between the light source and the image sensor, inline relative to the image sensor along the first axis;
- and
- 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.
2 more elements
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.
