Digital imaging ophthalmoscope

1. An opthalmoscope comprising:

a handle coupled to a head, wherein the head comprises:

a front section coupled with a diopter wheel, the front section including a view window; and

a back section fixedly attached to the front section, the back section comprising a diopter number viewer, a trigger button, and a digital imaging section, the digital imaging section comprising a liquid crystal display (LCD) screen and adapted to display an object in a field of view of the view window on the LCD screen;

wherein the trigger button is adjacent to the handle and positioned opposite the front section between the handle and the LCD screen; and

wherein the back section comprises a rounded projection rotatably coupled with a central hole in the diopter wheel, the rounded projection extending from a diopter surface in the back section substantially parallel with and in close proximity to the diopter wheel; and

wherein the diopter number viewer extends from the diopter surface away from the diopter wheel and comprises an opening configured to expose a diopter number on the diopter wheel.

2. The opthalmoscope of claim 1 , wherein the diopter number viewer permits light from a light source included in the handle to illuminate the diopter number.

3. The opthalmoscope of claim 1 , wherein the digital imaging section is configured to digitally zoom an image of the object displayed on the LCD screen.

4. The opthalmoscope of claim 1 , wherein the digital imaging section is configured to store one or more images of the object in the field of view of the view window in memory associated with the digital imaging section when the trigger button is pressed.

5. The opthalmoscope of claim 4 , wherein the digital imaging section is configured to allow annotations to be captured and stored in the memory for the one or more stored images of the object.

6. The opthalmoscope of claim 1 , wherein the digital imaging section further comprises one or more image review buttons, a Universal Serial Bus (USB) port, and an external switch.

7. A head for an opthalmoscope comprising:

a front section including a view window and fixedly attached to a back section, the front section and back section comprising a viewing axis where the view window of the front section lies on the viewing axis and the back section further comprises:

a diopter wheel comprising a plurality of diopters, each diopter being configured to align with the viewing axis through rotation of the diopter wheel;

a doublet lens located on the viewing axis, the doublet lens being configured to focus an image of an object in a field of view of the view window on a photosensor located on the viewing axis and included in a digital imaging section comprised in the back section;

a rounded projection rotatably coupled with a central hole in the diopter wheel, the rounded projection extending from a diopter surface in the back section substantially parallel with and in close proximity to the diopter wheel; and

a diopter number viewer extending from the diopter surface away from the diopter wheel and including an opening configured to expose a diopter number on the diopter wheel;

wherein the digital imaging section is configured to use the photosensor to create a digital image of the object and to display the digital image on a liquid crystal display (LCD) screen included in the digital imaging section and to store one or more images of the object in memory associated with the digital imaging section when a trigger button located adjacent to the diopter number viewer is pressed.

8. The head of claim 7 , wherein the diopter number viewer permits light from a light source included in the handle to illuminate the diopter number.

9. The head of claim 7 , wherein the digital imaging section is configured to digitally zoom the digital image of the object displayed on the LCD screen.

10. The head of claim 7 , wherein the digital imaging section further comprises one or more image review buttons, a Universal Serial Bus (USB) port, and an external switch.

11. The head of claim 7 , wherein a portion of the viewing axis between the plurality of diopters and the doublet lens is a nearly infinite corrected path.

12. The head of claim 7 , wherein the digital imaging section is configured to allow annotations to be captured and stored in the memory for the one or more stored images of the object.

13. In an opthalmoscope having a handle and a front section with a view window, the improvement comprises:

a back section fixedly attached to the front section, the back section comprising:

a digital imaging section, the digital imaging section comprising a liquid crystal display (LCD) screen and adapted to display an object in a field of view of the view window on the LCD screen, the digital imaging section including one or more image review buttons and a Universal Serial Bus (USB) port;

a trigger button adjacent to the handle and positioned opposite the front section between the handle and the LCD screen; and

a diopter number viewer extending away from a diopter wheel located between the front section and the back section, the diopter number viewer extending from a diopter surface included in the back section where the diopter surface is substantially parallel with and in close proximity to the diopter wheel;

wherein the diopter number viewer comprises an opening configured to expose a diopter number on the diopter wheel and the diopter number viewer is configured to permit light emitted from the handle to illuminate the diopter number.
