New technology makes it easier to diagnose neurodegenerative diseases A new combination of optical coherence tomography (OCT), adaptive optics and deep neural networks should enable better diagnosis and monitoring for neuron-damaging eye and brain diseases like glaucoma. Biomedical engineers at Duke University led a multi-institution consortium to develop the process, which easily and precisely tracks changes in the number and shape of retinal ganglion cells in the eye. This work appears in a paper published on May 3 in the journal Optica. The retina of the eye is an extension of the central...

by Michaela Kane — May 6, 2021 . DURHAM – A new combination of optical coherence tomography (OCT), adaptive optics and deep neural networks should enable better diagnosis and monitoring for neuron-damaging eye and brain diseases like glaucoma. Biomedical engineers at Duke University led a multi-institution consortium to develop the process, which easily and precisely tracks changes in the number and shape of retinal ganglion cells in the eye. This work appears in a paper published on May 3 in the journal Optica. The retina of the eye is an extension of the central nervous system. Ganglio...

The paper PNAS, 117:30661–69, 2020. Staring at her images of neurons in living humans’ eyes, Zhuolin Liu got an inkling that she could also see traces of another cell type on the surface of the retina. The images came from a study completed as part of her postdoctoral research at Indiana University (IU) Bloomington, and though the focus of that work had been neurons in the retina, the glimpse she got of what looked like macrophages led her to wonder if she and her colleagues could get a better view of the immune cells and probe their dynamics.   Macrophages on the surface of the retina l...

US Navy/MCS3 Jake Greenberg A Marine in California underwent a new kind of surgery to replace a benign tumor in his jaw using a reconstructed jaw made out of one of his leg bones and with 3D-printed teeth. Previously, such a surgery would take multiple surgeries and years of recovery, but those new techniques and technology mean the Marine will return to duty after just one surgery and a few months of recovery. A lucky Marine made military medical history by becoming the first service member to receive a reconstructed jaw made out of one of his leg bones, complet...
