Optical Coherence Tomography (OCT) angiography opens another exciting chapter in ophthalmic imaging. Based on motion contrast, and in the presence of motion-less structure, OCT angiography (OCT-A) resolves signal due to moving blood flow. It thereby offers a compelling alternative to…
In SD-OCT volumetric imaging you cannot always see Bruch’s membrane, the innermost layer of the choroid, lying at the base of the retinal layers. It is an important structural landmark for a variety of reasons and one that is important,…
The recent publication, “Real-Time Automatic Segmentation of Optical Coherence Tomography Volume Data of the Macular Region” by Tian et al. [1] raises the obvious question of what actually constitutes “real-time” processing? More broadly speaking, the paper reports on some segmentation…
OCT Angiography Technologies OHSU, Casey Eye Institute, July 25th, 2015. This past weekend I attended the first OCT angiography summit at the Casey Eye Institute, at Oregon Health and Science University. Held at an extremely impressive facility, this inaugural summit…
Neuronal loss of ganglion cells in the retina is an established hallmark of a number of diseases. As such, a number of clinical trials use the ganglion cell layer (GCL) thickness - or a complex thereof - as measured with…
