Abstract: A non-mydriatic, non-contact ultra-widefield fundus (u-WF) photographic imaging system and method are provided for performing u-WF photographic imaging of the eye. The non-mydriatic, non-contact u-WF photographic imaging system includes an illumination system that delivers trans-pars-planar illumination to the eyeball. This frees the entire pupil to be used for imaging. Freeing the entire pupil to be used for imaging allows a u-WFC of the non-mydriatic, non-contact u-WF photographic imaging system to use a relatively simple optics system to capture an ultra-wide FOV. Eliminating the need to dilate the pupil and the need to make contact with the eye while performing imaging eliminates the many problems associated with mydriatic, contact-mode fundus imaging systems and methods. In addition, the system can be implemented in a way that makes it highly suitable for telemedicine applications in underserved areas where clinics and trained healthcare providers may not be available.
