Abstract: Methods and apparatus are described for illuminating the fundus of an eye for wide-angle fundus photography. The present disclosure delivers light through a pars planar area of the eye for illuminating the interior of the eye, or through an eyelid and a pars plana of the eye. Trans-pars-planar illumination frees the entire pupil for imaging and therefore eliminates need for pupil dilation or complex balancing between illumination and imaging in previous wide-angle fundus photography based on trans-pupillary illumination. Additionally, the present disclosure discloses, when an optical fiber bundle multiple-channel trans-pars-planar illuminator placed adjacent to the pars plana, at least one optical fiber in the optical fiber bundle aligns with the pars plana to deliver light through the pars plana into the fundus of the eye, thus eliminating the previous problem of having to move an optical fiber to search a location of the pars plana.
