This microscopic🔬 object is a specialized immune cell (microglia) that resides in your retina👁️ and is responsible for damage control and refinement of neural circuits. GFP labeled

🔬Our team @urochestersmd.bsky.social is building a 📹camera to image through layers of the living eye👁️. By changing focus, we reject out-of-focus light to image 3 layers of retinal vessels

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

Good news indeed. Michael's advocacy for the importance of Eye research dovetail with his diplomacy in challenging environments. Lets keep this going...

@arvoinfo.bsky.social members, remember to cast your vote for the 2025 ARVO Scientific Image Contest! Review the fabulous finalists and select your favorite by Nov. 14: https://bit.ly/4mNNbq8
this one is around 250 microns (about the thickness of a human hair or two)
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

thank you. visualization in FIJI. We use both Adaptive Optics Ophthalmoscopy and conventional confocal histology

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.
