Abstract: A system includes a vision screening device having at least one sensor. The system also includes a controller operably connected to the at least one sensor. The controller is configured to cause the at least one sensor to obtain an image of an eye, and to identify a region of interest associated with a macula of the eye. The controller is also configured to identify drusen disposed proximate the macula, and to generate an augmented image of the eye. The augmented image includes a component indicating the drusen.

Abstract: A fundus imager includes a handheld housing that supports a lighting unit configured to illuminate an eye fundus. The lighting unit includes one or more light-emitting diodes. The housing further supports a camera configured to capture one or more images of the eye fundus, and a display configured to display the one or more images of the eye fundus. The fundus imager captures at least one multispectral fundus image using the camera, and displays the at least one multispectral fundus image on the display.
