Retinal image capturing
An apparatus for producing a fundus image includes: a processor and a memory; an illumination component including a light source and operatively coupled to the processor; a camera including a lens and operatively coupled to the processor, wherein the memory stores instructions that, when executed by the processor, cause the apparatus to: execute an automated script for capture of the fundus image; and allow for manual capture of the fundus image.
1. An apparatus for producing a fundus image, the apparatus comprising:
a processor and memory;
a light source;
a camera;
a display, and
an outer housing including:
a first end supporting the display;
a second end configured to engage an eye; and
an elongated portion extending between the first end and the second end to form a cylindrical barrel, wherein the cylindrical barrel is sized to be held by a caregiver;
wherein the memory stores instructions that, when executed by the processor, cause the apparatus to:
illuminate the eye with the light source;
display a target element on the display;
display a bright spot on the display, the bright spot being a reflection of the light source by a retina of the eye;
update a position of the bright spot on the display as the apparatus is moved relative to the eye; and
automatically initiate image capture with the camera when the bright spot is within the target element on the display.
2. The apparatus of claim 1 , wherein the target element is a geometric shape that is displayed on the display.
3. The apparatus of claim 2 , wherein the geometric shape is a diamond.
4. The apparatus of claim 1 , wherein the caregiver uses micro adjustments of the cylindrical barrel to move the bright spot into the target element.
5. The apparatus of claim 1 , wherein the light source is an infrared light source.
6. The apparatus of claim 1 , wherein the target element is positioned within an upper half of the display.
