Abstract
A novel mobile device attachment that allows the mobile device to obtain photography and videography of the fundus oculi. This mobile device attachment does not require condensing lenses or an additional power source as it redirects the native mobile device light source using a series of three mirrors to be in line with the camera of the mobile device. Ultimately, this novel mobile device attachment creates an upright, non-inverted, magnified image of the fundus oculi.
Claims16
An optical accessory for a mobile device having a device surface containing a light source and a camera having a viewing direction, the optical accessory comprising:
- a light channel containing a first optical element, a second optical element and a third optical element, wherein the first optical element is configured to reflect light from the light source to the second optical element, wherein the second optical element is configured to reflect light to the third optical element, wherein the third optical element is configured to reflect light toward a fundus oculi of an eye to be examined,
- wherein the first optical element and second optical element direct light from the light source along the light channel and parallel to the surface, and the third light element reflects light from the light channel in a direction perpendicular to the device surface such that light from the third light element is in alignment with and nearly coaxial with the viewing direction of the camera in such a way as to direct the light to the fundus oculi of an eye to be examined by the camera to thus create an ophthalmoscope system which allows a view of the fundus oculi.
A method for obtaining images of a fundus oculi of an eye to be examined, the method comprising:
- attaching an optical accessory to a mobile device having a device surface containing a light source and a camera having a viewing direction, wherein the optical accessory comprises a light channel containing a first optical element, a second optical element and a third optical element;
- and wherein the optical accessory is aligned with the mobile device so that the first optical element is aligned with the light source so as to receive light from the light source;
- introducing light from the light source to the first optical element,
- reflecting light received by the first optical element to the second optical element through a first portion of a light channel that is parallel with the device surface;
- reflecting light from the second optical element to the third optical element through a second portion of the light channel that is parallel with the device surface;
- reflecting light from the third optical element toward the fundus oculi so as to produce image light of the fundus oculi, wherein the third light element reflects light from the light channel in a direction perpendicular to the device surface such that light from the third light element is in alignment with and nearly coaxial with the viewing direction of the camera;
- receiving image light from the fundus oculi in such a way to create an ophthalmoscope system which allows a view of the fundus oculi so as to produce an image with the camera.
