The retina is the innermost, light-sensitive layer, or "coat", of shell tissue of the eye of most vertebrates and some molluscs. The optics of the eye create a focused two-dimensional image of the visual world on the retina, which translates that image into electrical neural impulses to the brain to create visual perception, the retina serving much the same function as film or a CCD in a camera.

In the present book, twelve typical literatures about retinal repair published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on Retinal-Ischemia, Retinal Laser Technology, Selective Retinal Therapy, Retinal Coordinate and Retinal Pigment Epithelium, etc. We hope this book can demonstrate advances in retinal repair as well as give references to the researchers, students and other related people.
