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.

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.
