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 image sensor;
a lens positioned between the light source and the image sensor, inline relative to the image sensor along the first axis;
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;
a control unit comprising a processor and a tangible storage device storing program instructions executable by the processor, the program instructions comprising instructions to;
emit, by the visible light source, at least two beams of visible light in sequence, during a period of time for visible light emission, by energizing the visible light source via the power source, the at least two beams of visible light comprising a first beam of visible light having a first energy and a second beam of visible light having a second energy greater than the first energy; and
an input/output (I/O) device, wherein the program instructions further comprise instructions to;
detect, by the image sensor, a response time of pupil constriction in the eye in response to emitting the at least two beams of visible light;
generate, by the processor, a delta report comprising data showing a divergence between the measured response time of pupil constriction and an expected response time of pupil constriction; and
output, by the I/O device, the delta report.

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.

7. 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; 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; at least one control unit comprising a processor and a tangible storage device storing program instructions executable by the processor, the program instructions comprising instructions to; emit, by either or both of respective visible light sources of the first compartment and the second compartment, at least two beams of visible light in sequence in one compartment, during a period of time for visible light emission, by energizing the visible light source via the power source, the at least two beams of light comprising a first beam of visible light having a first energy and a second beam of visible light having a second energy greater than the first energy; and an input/output (I/O) device, and wherein the program instructions further comprise instructions to; detect, by the image sensor, a response time of pupil constriction in the eye in response to emitting the at least two beams of visible light in the first compartment, the second compartment, or both; generate a delta report comprising data showing a divergence between the measured response time of pupil constriction and an expected response time of pupil constriction; and output, by the I/O device, the delta report. - View Dependent Claims (8, 9, 10, 11, 12)
