Optical Coherence Tomography Angiography of the Optic Disc; an Overview. [PDF]

, 2017
Different diseases of the optic disc may be caused by or lead to abnormal vasculature at the optic nerve head. Optical coherence tomography angiography (OCTA) is a novel technology that provides high resolution mapping of the retinal and optic disc ...

Optical coherence tomography angiography in uveitis [PDF]

Journal of Ophthalmic Inflammation and Infection, 2019
AbstractBefore the introduction of optical coherence tomography angiography (OCTA) in the early 2000s, dye-based angiography was considered the “gold standard” for the diagnosis and monitoring of ocular inflammation. OCTA is a novel technique, which demonstrates capillary networks based on the amount of light returned from moving blood cells, providing

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Single‐Cell RNA Sequencing of Retina Reveals Nna1 Upregulation in Myopic Diabetic Retinopathy as a Protective Factor Against Diabetic Damage

Advanced Science, EarlyView.
This study investigates a schematic overview of the mechanistic pathways. The relationship between myopia and DR has long been of clinical interest. In diabetic mice, Nna1 expression is downregulated, whereas in diabetic mice with FDM, Nna1 expression is upregulated–particularly in Müller cells–accompanied by decreased vascular endothelial growth ...

Multimodal Optical Imaging and Modulation with Simultaneous Electrophysiology Through Smart Dura in Non‐Human Primates

Advanced Science, EarlyView.
This study demonstrates multimodal integration in non‐human primates, combining large‐scale, high‐density electrophysiology using Smart Dura with optical techniques such as multiphoton imaging (MPI), photothrombotic lesioning, optical coherence tomography angiography (OCTA), wide‐field intrinsic signal optical imaging (ISOI), and optogenetics.
