March is Women’s History Month. It’s time to look back on the women who have influenced the field of optometry. Over the past few years, women have been publishing more research in optometry and playing a more important part in advancing vision health. Michelle C. Callegan, PhD is one of these women. As the director of Vision Research at the University of Oklahoma, her work focuses on a condition known as bacterial endophthalmitis. By studying this type of infection on a molecular level, Dr. Callegan is developing a better understanding of retinal function. Her research could improve our understanding of the blood-ocular barrier and how diabetes can make eye infections worse. Her goal is to develop new treatments for bacterial infections.
