Abstract
Retinal imaging systems and methods are described. In an embodiment, the retinal imaging system includes an eyepiece lens assembly; an image sensor adapted to acquire a retinal image of an eye through the eyepiece lens assembly; a dynamic fixation target optically coupled to the eyepiece lens assembly such that the dynamic fixation target is viewable through the eyepiece lens assembly; and a controller communicatively coupled to the image sensor and the dynamic fixation target. In an embodiment, the dynamic fixation target includes a display where an image generated by the display is controlled by a position of a user's eye relative to the eyepiece lens assembly.
