Retinal image capturing
View Patent ↗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 a memory;
an illumination component including a light source;
a camera; and
a display,
wherein the memory stores instructions that, when executed by the processor, cause the apparatus to:
display an image of an eye;
display a target element on the display;
display a light source reflection on the image of the eye on the display, the light source reflection being a reflection of light from a retina of the eye;
update a position of the light source reflection on the display as a caregiver manipulates a position of the apparatus relative to the eye; and
automatically initiate fundus image capture with the camera when the light source reflection is within the target element on the display.
2. The apparatus of claim 1 , wherein the light source reflection is circular.
3. The apparatus of claim 1 , wherein the target element is a geometric shape that is displayed on the display.
4. The apparatus of claim 3 , wherein the geometric shape is a diamond.
5. The apparatus of claim 1 , further comprising a housing, wherein the housing includes a first end supporting the display and a second end configured to engage the eye.
6. The apparatus of claim 5 , wherein the housing is elongated to form a barrel.
7. The apparatus of claim 6 , wherein the caregiver uses micro adjustments of the barrel to move the light source reflection into the target element.
8. The apparatus of claim 6 , wherein the barrel is sized to be held by the caregiver.
9. The apparatus of claim 1 , wherein the light source is an infrared light source.
10. The apparatus of claim 1 , wherein the target element is positioned within an upper half of the display.
