Abstract

This study is to validate the trans-pars-planar illumination for ultra-widefield multispectral imaging (MSI) of the retina and choroid. By freeing the available pupil for collecting imaging light only, the trans-pars-planar illumination enables a portable, nonmydriatic fundus camera, with 200o FOV in a single-shot image. The trans-pars-planar illumination, delivering illumination light from one side of the eye, naturally enables oblique illumination ophthalmoscopy to enhance the contrast of fundus imaging. Four wavelength LEDs, including 530 nm, 625 nm, 780 nm, and 970 nm, are illuminated for MSI of the retina and choroid.
