Ocular Vascular Occlusive Disorders

Sohan Singh Hayreh, MD, MS, PhD, DSc, FRCS, FRCOphth, is a world-renowned clinical scientist with more than 55 years' experience in basic, experimental, and clinical research in ophthalmology. In 1973 he was appointed Professor of Ophthalmology at the University of Iowa, Iowa City, and Director of the Ocular Vascular Clinic and Ocular Vascular Research Laboratory, and in 1999 became Professor Emeritus of Ophthalmology. His career dates back to the 1950s. In 1961 he was awarded the prestigious Beit Memorial Research Fellowship in Medical Sciences at the Institute of Ophthalmology, University of London. In subsequent decades Professor Hayreh made many seminal observations in the field and often challenged conventional thinking and dogmas. He has received numerous international honors and awards and has delivered several prestigious honorary lectures, including the Duke-Elder Lecture at the Royal College of Ophthalmologists, the William Mackenzie Lecture at the University of Glasgow, and the 2008 Green Lecture. He received the von Sallmann Prize for 1994 and the Arnall Patz Medal of the Macula Society in 2001. In 2002 Professor Hayreh was guest of honor at the annual meeting of the American Academy of Ophthalmology, from whom he received a Senior Achievement Award in the following year. Also in 2003 he received the Mildred Weisenfeld Award for Excellence in Ophthalmology from the Association for Research in Vision and Ophthalmology. He continues to serve on the editorial boards of various leading journals, and has published over 400 papers in peer-reviewed journals and more than 40 book chapters.
