Bethesda, MD

Steven L. Bernstein, MD, PhD

Professor, Ophthalmology and Visual Sciences

University of Maryland School of Medicine

Dr. Steven Bernstein and his laboratory interests center on age-related and genetically associated optic nerve diseases, in particular nonarteritic anterior ischemic optic neuropathy (NAION), which is a stroke of the optic nerve, and the most common cause of sudden optic nerve-related vision loss. During the last five years, his laboratory has developed new ways to identify stem cells that may both contribute to normal nerve function, and aid in repair of optic nerve injury.

What do Reactive Astrocytes (really) Do

June 4, 2026 — 12:00 pm to 1:00 pm ET

Bethesda, MD

Shane Liddelow, PhD

Associate Professor

NYU Grossman School of Medicine

Dr. Shane Liddelow's primary research focus is on understanding the complex roles of astrocytes in the brain. Astrocytes are a type of glial cell that play crucial roles in maintaining brain homeostasis, supporting neuron function, and responding to injury. His work has particularly centered on a subtype of reactive astrocytes that we discovered, which release toxic factors capable of killing specific neurons.

Past Seminars

Geographic atrophy in age-related macular degeneration: A tale of two stages

June 5, 2025 — 12:00 pm to 1:00 pm ET

Bethesda, MD

The seminar will be presented by Tiarnan Keenan, M.D, Ph.D., Stadtman Investigator in the Division of Epidemiology and Clinical Applications.

Dr. Keenan's research is focused on adult retinal disease, particularly age-related macular degeneration (AMD), the leading cause of legal blindness in all developed countries. This includes research into the diagnosis, treatment, and prevention of AMD, together with disease mechanism discovery.

His experience and research span multiple disciplines. In genetics, his research into genotype-phenotype relationships has suggested that AMD consists of multiple partially distinct disease entities. His biochemical and anatomical research has provided insights into how AMD arises at the molecular level. In the clinical arena, his research involves examining how AMD behaves over time and how its progression may be slowed. For example, he has completed a landmark study of geographic atrophy, the dry form of advanced AMD, and is currently undertaking a detailed study showing how particular dietary patterns can slow down AMD progression.

His lecture, titled “Geographic atrophy in age-related macular degeneration: a tale of two stages,” expands further on this ongoing research and the novel discoveries resulting from such studies.
