Neutrophils are white blood cells that circulate in our blood. When they reach capillaries, they compress & fill these vessels. Derek Power et al via:👇👇

Cells color coded for depth! each color represents a different layer of the retina. All the same "class" of cell that are CX3CR1 positive mostly microglia -but also macrophages, monocytes and some hyalocytes

Watch to the end! Immune cells in the retina remain flat until damage is detected. Cells change their shape and dive deep in response to damage (pink cell)

Flaum Researcher Jesse Schallek, Ph.D., posing in front of optical research equipment, in front of a white board and an optical imaging poster.

Our next researcher at the Optica meeting is Jesse B. Schallek, Ph.D., who along with his lab, studies how blood flows through the vessels in the retina. They aim to understand how changes in this neural-vascular network contribute to retinal diseases and vision loss.

Microglia (white/green) are immune cells that live in specific layers in the retina.
In response to injury, they migrate into location of damage.

Meet Dr. Sara Patterson, a researcher at Flaum who is participating in the Emerging Vision Scientist Program.

Her lab studies how the eye communicates with the brain. This groundbreaking work is paving the way for new treatments to restore vision.

Thank you, Rep. Morelle, for visiting the Flaum Eye Institute to discuss and see firsthand how NEI-funded research improves patient care and drives innovation in ophthalmology. We are grateful for your support and recognition of the important role federally funded research plays.
