About our work

High resolution fluorescence imaging of ocular tissues presents unique opportunities as well as technical challenges for scientists attempting to visualize pathological changes in the cornea, lens, retina or retinal pigment epithelium. Exploiting the transparency of the vertebrate eye and innovations in ocular imaging, vision researchers and ophthalmologists have gained unprecedented insight into a wide array of ocular processes.

The National Eye Institute's Biological Imaging Core provides NEI scientists with a wide range of high resolution imaging and analysis applications including confocal microscopy, multi-photon imaging, Airyscan super-resolution, deconvolution, laser capture microdissection, in vivo and in vitro imaging. The primary objective of the Biological Imaging Core is to pair state-of-the-art instrumentation with novel imaging approaches to provide vision scientists new avenues for studying ocular disease processes.
