Retina: The Retina is the light-sensitive tissue at the back of the eye. When light enters the eye, the retina changes the light into nerve signals. The retina then sends these signals along the optic nerve to the brain. Without retina function, the eye cannot communicate with the brain, making vision impossible.

This was completed at the California Pacific Medical Center in San Francisco. After completion of his fellowship, Dr. Mansour was retained by Stanford University where he was appointed as Assistant Clinical Professor of Ophthalmology. He was also Director of the Retina service and Associate Chief of the Division of Ophthalmology at Santa Clara Valley Medical Center (SCVMC), a major teaching hospital in the Stanford University Health Care system. He remained there until he joined the faculty at George Washington University in 2003 where he is currently a Clinical Professor in the Department of Ophthalmology.

Throughout these years, Dr. Mansour has been involved in several areas of both basic science and clinical retinal research. He has presented his extensive research at numerous national and international conferences including the American Academy of Ophthalmology, Association for Research in Vision and Ophthalmology, and the Joint Commission on Allied Health Personnel in Ophthalmology. He has also authored and co-authored several articles in peer review journals including Archives of Ophthalmology, American Journal of Ophthalmology, Ophthalmology, Retina, the Canadian Journal of Physiology and Pharmacology, the Canadian Journal of Ophthalmology, Investigative Ophthalmology & Visual Science and the New England Journal of Medicine.
