Loyola World Mission Symposium
The first Annual Foreign Ophthalmology Mission day was held on May 12, 2004. At that time, James E. McDonald, MD, and Richard Gieser, MD, were honored as recipients of the Outstanding Humanitarian Award by the American Academy of Ophthalmology.
In 2008 the Foreign Ophthalmology Missions Day conference was combined with the Loyola Ophthalmology Resident Alumni Day and inaugurated the Richard G. Gieser, MD World Service Lecture.
Beginning in 2015 the conference has been hosted independently as the Annual Loyola World Mission Symposium.

Richard G. Gieser, MD, World Service Lecture
Dr. Gieser received his medical degree from Baylor University in Houston, Texas. He completed his residency at the Illinois University Eye and Ear Infirmary and a fellowship in retinal and vitreous surgery at Cornell- New York Hospital.
Dr. Gieser was born in China where his father was a missionary doctor. Following his father’s example, Dr Gieser has made annual trips to underserved communities around the world to help those with visual loss. Moreover he has volunteered over many years as a “missionary teacher” in numerous medical schools abroad. He has brought his expertise as a retina physician and his Christian spiritual message to medical schools in China, India, Pakistan, Bulgaria, Romania, Nigeria, Uganda, Siberia, and Afghanistan.
As a member of the Department of Ophthalmology for 30 years (1978-2008) Richard Gieser, MD, provided significant leadership and support for the department’s tradition for active engagement in ophthalmic care to the world community.
(Pictured:May Khadem, MD, Richard Gieser, MD, Eileen Gable, OD and David Yoo, MD)Dr Gieser’s commitment, enthusiasm, and dedication for world service serve as an example to all physicians and non-physicians alike. His energy and passion for lifelong learning have served to inspire faculty and residents.
The Richard Gieser World Service Lecture will serve as a tribute to his dedication to those in need of eye care and throughout the world as well as to his commitment to resident education in the Department of Ophthalmology.
