Before taking a look at retinal scanning, here is a little about the equiptment and the retina itself.

       The retina is a very complex and dynamic structure of the eye. It is truly a window to the body, giving us extraordinary access to the microcirculation of the body as well as the eye and to the central nervous system. At the same time, its transparency and sequestered location within the inner lining of the globe challenges our technical facility for revealing its secrets without disturbing it function. Towards the purpose we have enlisted a growing number state-of-the-art imaging devices that provide quantitative and real-time analysis of the retinal structure and function.

           A historical perspective of retinal imaging allows us to move forward in our work. Our aim is to provide doctors and their patients with the most advanced diagnostic tools available to visualize and understand the human retina. Corollary to this, we participate in the development of new technology for the advancement of this field. We are likewise involved in that further increase our understanding of the normal and diseased retina, as well as the effects of new therapies on various disease states.

The Structure The Challenge
Transparent structure 100-250 Ám thick Resolution of microanatomy
127 million photoreceptors (7M cones and 120M rods) Quantitative analysis of structures and function
1.2M optic nerve fibers – 100 fold internal integration Panoramic viewing
Dynamic sensitivity range spans 11 orders of magnitude Functional imaging
  Real-time dynamic imaging
