‘Less is more’: Retinal imaging tweaks boost resolution by 33% – Health Imaging

For their study, the NEI team worked with a group of Stanford University investigators to tweak adaptive optics retinal imaging systems and block out some of the extra light that illuminates the eye.
Doing so created a ring of light, rather than a disk, Tam and colleagues reported. And after further adjusting the light coming back from the eye using a tiny pinhole, the group increased traditional retinal imaging resolution by 33%.
Sometimes rods are hard to image because they are so small, first…
