Description

Project Summary/Abstract Powerful new Adapative Optics imaging technoIogies which sense ocular aberrations with a wave- front sensor and corrects them with a deformable mirror wave-front compensator, like Adaptive Optics Scanning Laser Ophthalmoscopy (AOSLO) and AO-OCT, provide detailed anatomical, physiological and functional information at the cellular level in the human eye. Physical Sciences Inc. (PSI) has recently demonstrated a new approach, called adaptive optics line scanning ophthalmoscopy (AO-LSO). The clinical AO-LSO retinal imager, invented and developed at PSI, greatly simplifies AO optical design, eliminates high-speed scanning components, and reduces the clinical footprint compared to research AOSLOs, while preserving many of the advantages of (line-)confocal imaging for resolving retinal layers. Although the AOSLO and AO-LSO provide the ability to routinely image and count cone photoreceptors, at present, there are no direct approaches for in vivo imaging of retinal ganglion cells in the hum
