Trans-pars-planar illumination enables 200°
ultra-wide field pediatric fundus photography
for easy examination of the retina
Posted on 2019-12-05 - 22:03
This study is to test the feasibility of using trans-pars-planar illumination for ultrawide
field pediatric fundus photography. Fundus examination of the peripheral retina is
essential for clinical management of pediatric eye diseases. However, current pediatric fundus
cameras with traditional trans-pupillary illumination provide a limited field of view (FOV),
making it difficult to access the peripheral retina adequately for a comprehensive assessment
of eye conditions. Here, we report the first demonstration of trans-pars-planar illumination in
ultra-wide field pediatric fundus photography. For proof-of-concept validation, all off-theshelf
optical components were selected to construct a lab prototype pediatric camera
(PedCam). By freeing the entire pupil for imaging purpose only, the trans-pars-planar
illumination enables a 200o FOV in a snapshot fundus image, allowing easy visualization of
both the central and peripheral retina up to the ora serrata. A low-cost, easy-to-use ultra-wide
field PedCam provides a unique opportunity to foster affordable telemedicine in rural and
underserved areas.
