Abstract

A portable retinal imaging device for imaging the fundus of the eye. The device includes an ocular imaging device containing ocular lensing and filters, a fixation display, and a light source, and is configured for coupling to a mobile device containing a camera, display, and application programming for controlling retinal imaging. The light source is configured for generating a sustained low intensity light (e.g., IR wavelength) during preview, followed by a light flash during image capture. The ocular imaging device works in concert with application programming on the mobile device to control subject gaze through using a fixation target when capturing retinal imaging on the mobile device, which are then stitched together using imaging processing into an image having a larger field of view.
