      Functional retinal imaging using adaptive optics swept-source OCT at 1.6  MHz
      Objective optical assessment of photoreceptor function may permit earlier diagnosis of retinal disease than current methods such as perimetry, electrophysiology, and clinical imaging. In this work, we describe an adaptive optics (AO) optical coherence tomography (OCT) system designed to measure functional responses of single cones to visible stimuli. The OCT subsystem consisted of a raster-scanning Fourier-domain mode-locked laser that acquires A scans at 1.64 MHz with a center wavelength ...

      En face optical coherence tomography imaging of beta and gamma parapapillary atrophy in high myopia
      Objective Recent studies have suggested that optical coherence tomography (OCT)-based classification of parapapillary atrophy (PPA) may be helpful in distinguishing glaucomatous from myopic optic disc changes. However, the pathological implications of PPA may be different in highly myopic eyes that exhibit optic disc deformations distinct from low to moderate myopia. Therefore, we conducted the current study to investigate factors associated with OCT-defined PPA zones measured in en face reconstructed ...

      Reduced Ganglion Cell Volume On Optical Coherence Tomography In Patients With Geographic Atrophy
      Purpose: Geographic atrophy (GA) is the sequelae of macular degeneration. Automated inner retinal analysis using optical coherence tomography is flawed because segmentation software is calibrated for normal eyes. The purpose of this study is to determine whether ganglion cell layer (GCL) volume is reduced in GA using manual analysis. Methods: Nineteen eyes with subfoveal GA and 22 controls were selected for morphometric analyses. Heidelberg scanning laser ophthalmoscope optical coherence tomography ...

      Potential clinical applications of optical coherence tomography angiography in glaucoma
      Editorial: Elevated intraocular pressure has been identified as a major risk factor for primary open-angle glaucoma (POAG), and current treatments focus on reducing the intraocular pressure to prevent disease progression. However, some glaucomatous patients continue to progress despite intraocular pressure lowering, and in these patients, other risk factors like decreased ocular perfusion pressure and vascular dysfunction may be causative factors. 1 , 2 The recent advent of optical coherence tomography angiography ...

      Channel dispersed Fourier transform spectrometer
      The high signal throughput of Fourier transform spectroscopy has proved a boon to overcoming the difficulties of otherwise overwhelming detector noise in chemical infrared spectroscopy and near-infrared Raman spectroscopy, and is desirable for in situ measurement. Here we introduce a stationary channel dispersed Fourier transform (CDFT) spectrometer that efficiently utilizes two-dimensional imagers to obtain high-resolution input spectra in low-pixel-density imagers. By angularly dispersing a vertical one-dimensional interference pattern along a ...
