The knowledge of the pathogenesis of retinal affections, a major cause of blindness, has
greatly benefited from recent advances in retinal imaging. However, optical aberrations
of the ocular media limit the resolution that can be achieved by current techniques.
The use of an adaptive optics system improves the resolution of ophthalmoscopes by
several orders of magnitude, allowing the visualization of many retinal microstructures:
photoreceptors, vessels, bundles of nerve fibers.
Recently, the development of the coupling of the two main imaging techniques, the
Adaptive Optics Ophthalmoscope with Optical Coherence Tomography, enables unparalleled
three-dimensional in vivo cell-scale imaging, while remaining comfortable for the
patients.
The purpose of this project is to evaluate the performance of this system for imaging
micrometric retinal structures.
