Finding Better Ways to Image the RetinaPosted on May 13th, 2021 by Dr. Francis CollinsCredit: Johnny Tam, National Eye Institute, NIHEvery day, all around the world, eye care professionals are busy performing dilated eye exams. The great news is that, thanks to research, retinal imaging just keeps getting better and better. Thanks to colorization and other techniques, a viewer can readily distinguish between the light-sensing, color-detecting cone cells (orange) and the much smaller, lowlight-sensing rod cells (blue). These high-res images come from Johnny Tam, a researcher with NIH’s National Eye Institute. Working with Alfredo Dubra, Stanford University, Palo Alto, CA, Tam and his team figured out how to limit light distortion of the rod cells.
