TLDR
OCT as discussed by the authors uses low-coherence interferometry to produce a two-dimensional image of optical scattering from internal tissue microstructures in a way analogous to ultrasonic pulse-echo imaging.Abstract:
A technique called optical coherence tomography (OCT) has been developed for noninvasive cross-sectional imaging in biological systems. OCT uses low-coherence interferometry to produce a two-dimensional image of optical scattering from internal tissue microstructures in a way that is analogous to ultrasonic pulse-echo imaging. OCT has longitudinal and lateral spatial resolutions of a few micrometers and can detect reflected signals as small as approximately 10(-10) of the incident optical power. Tomographic imaging is demonstrated in vitro in the peripapillary area of the retina and in the coronary artery, two clinically relevant examples that are representative of transparent and turbid media, respectively.read more

TL;DR: OCT-A provides detailed images of retinal vascular plexuses and quantitative data of pathologic structures and further studies are warranted to define the role of OCT-A in the assessment of retinovascular diseases, with respect to conventional FA and ICG-A.

TL;DR: In this paper, a semiconductor optical amplifier (SOA) in a laser ring is chosen to provide low polarization-dependent gain (PDG) and a booster SOA, outside of the ring, is selected to provide high PEG.

TL;DR: Nerve fiber layer defects expanded with time, often by the development and coalescence of adjacent areas of damage, and field defects closely corresponded, but nerve fiber layer loss was generally more widespread.

Retinal ganglion cell atrophy correlated with automated perimetry in human eyes with glaucoma.
TL;DR: Estimates suggest that visual field sensitivity in automated testing begins to decline soon after the initial loss of ganglion cells in human eyes with glaucoma, and that this decline is most pronounced in areas that had 0-dB sensitivity in the field test.
