How Does Space Travel Affect the Eyes?

How the human body reacts to the transition to deep-space travel – and 
then adapts, or doesn’t, to lengthy periods in a microgravity environment – 
remains a largely understudied area. Our guest, Prem Subramanian, MD, 
PhD, chief of neuro-ophthalmology at the University of Colorado School of 
Medicine, talks about how space travel, including long-duration spaceflight, 
affects the eyes and how advancements in neuro-ophthalmology are helping 
astronauts. He also discusses treatments for thyroid eye disease and 
strabismus and shares research that seeks to understand eye issues in 
patients who’ve suffered from multiple traumatic brain injuries.
