Gianmarco Vizzeri

Gianmarco Vizzeri, MD, is a Professor and Vice Chair of Clinical Operations in the Department of Ophthalmology and Visual Sciences at the University of Texas Medical Branch (UTMB). He serves as Medical Director of the Ophthalmology Clinical Research Center, leading advanced glaucoma diagnostics and therapeutic innovation. His clinical practice focuses on glaucoma management at UTMB Eye Centers in Galveston and Friendswood.

Dr. Vizzeri earned his Medical Degree in Medicine and Surgery from the University of Turin, Italy, completed his Ophthalmology Residency at the same institution, and undertook a Clinical and Research Fellowship at the Hamilton Glaucoma Center, University of California San Diego.

His research integrates ocular imaging, microgravity effects, and surgical outcomes. Key interests include:

• Spaceflight-associated neuro-ocular syndrome (VIIP) pathophysiology
• Retinal vascular patterning using VESGEN analysis
• Glaucoma neurodegeneration mechanisms
• Innovations in trabeculectomy techniques
• Translational applications of terrestrial microgravity analogs

His recent publications (2020-2025) demonstrate a dominant focus on:

• Ocular adaptations to microgravity in astronauts
• Neuroprotective strategies for glaucoma
• Advanced imaging modalities for anterior/posterior segment analysis
• Surgical refinements to minimize refractive complications

This reflects sustained contributions to space ophthalmology and glaucoma therapeutics.

Dr. Vizzeri collaborates with NASA and leads the UTMB Ophthalmology Clinical Research Center team, investigating novel diagnostic and therapeutic approaches for vision preservation in extreme environments.
