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

Structure-Function Relationships With Spectral-Domain Optical Coherence Tomography Retinal Nerve Fiber Layer and Optic Nerve Head Measurements
TL;DR: The structure-function relationship was significantly stronger with BMO-MRW than other ONH SD-OCT parameters, and the best diagnostic capabilities were seen with rim area and average RNFL.

TL;DR: The optical coherence tomography (OCT) technique is applied to distinguish artificial materials commonly used for spoofing fingerprint scanning systems from the real skin to demonstrate that an autocorrelation analysis of the OCT images could be potentially used in automatic recognition systems.

TL;DR: The reproducibility of AC angle measurements was good to excellent for the nasal and temporal quadrants and may be unique to this prototype due to difficulty in acquiring high-quality images of the inferior angle.

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.
