The International Society of Geographical and Epidemiological Ophthalmology was established in 1970 to promote research and learning across eye professionals internationally. The history of ISGEO is best told through this talk by founder Dr. Elizabeth Cass and this article by Dr. James Ganley about her remarkable life For nearly 40 years thereafter, Dr. James Ganley stewarded ISGEO with the loving partnership of his wife Anne. This reflection on Jim Ganley’s passing in 2020 attempts to capture his dedication and contributions to ISGEO.

Today, ISGEO enhances access to research, research skills and collaborations among the growing number of professionals at the intersection of public health and eye health.

ISGEO Congresses held in 18 countries to date offer scientific talks based on peer-reviewed publications and discussion of issues faced by researchers. Featured speakers from the past several Congresses have included noted researchers including Professor Clare Gilbert, Professor Hannah Faal, Dr Hans Limburg, Professor Allen Foster, Professor Gordon Johnson, Dr. Serge Resnikoff, Dr. Paul Courtright, and Professor Marilyn Miller among others.

The ISGEO-related journal, Ophthalmic Epidemiology, is dedicated to the publication of original research into eye and vision health in the fields of epidemiology, public health and the prevention of blindness.
