Retinal imaging goes high resolution

Good news! Probably this will allow e.g. earlier detection of age-related macular degeneration.



"The EPFL team developed a radically different technique for imaging retinal cells with high contrast and high resolution. Rather than sending light through the pupil, the new technique, which they have dubbed transscleral optical phase imaging (TOPI), illuminates the white part of the eye (the sclera). This tactic greatly increases the contrast of many retinal structures ... A third advantage stems from the fact that the team image the reflected light from the retina using a conventional transpupillary advanced optics (AO) camera system. This system corrects eye aberrations in real time, enabling them to obtain cellular-level resolution images."
