A fundus imaging system includes: an image sensor array, where the image sensor array includes monochrome photodiodes and global shutter control, an illumination unit with one or more light-emitting diodes that have one or more dies, a computing system including a processor and memory, one or more lenses, one or more reflective mirrors, and a display. In an example method of use, a clinician positions a patient, initiates a focal adjustment, initiates a retinal imaging process, and the same or a different clinician views the image. In some embodiments, the imaging system is configured to analyze the image and identify detected physical attributes in the image relating to the diagnosis and treatment of diabetic retinopathy. |

1. A non-mydriatic fundus imaging system, comprising:
an image sensor array including a two-dimensional monochrome complementary metal-oxide-semiconductor, wherein the image sensor array has a plurality of rows of pixels, and the image sensor array is capable of global reset operations wherein each pixel of the plurality of rows of pixels is exposed substantially simultaneously; an illumination unit operatively coupled to the image sensor array, wherein the illumination unit includes a light emitting diode, and the illumination unit being capable of overdriving the light emitting diode; a timing unit operatively coupled to the image sensor array and the illumination unit and configured to simultaneously expose a full frame of pixels of the image sensor array during an exposure period, wherein the illumination unit is configured to overdrive the light emitting diode during the exposure period. |
