      Label‐free volumetric imaging of conjunctival collecting lymphatics ex vivo by optical coherence tomography lymphangiography
      We employ optical coherence tomography (OCT) and optical coherence microscopy (OCM) to study conjunctival lymphatics in porcine eyes ex vivo . This study is a precursor to the development of in vivo imaging of the collecting lymphatics for potentially guiding and monitoring glaucoma filtration surgery. OCT scans at 1300 nm and higher‐resolution OCM scans at 785 nm reveal the lymphatic vessels via their optical transparency. Equivalent signal characteristics are also ...

    7. Method to investigate temporal dynamics of ganglion and other retinal cells in the living human eye

      Method to investigate temporal dynamics of ganglion and other retinal cells in the living human eye
      The inner retina is critical for visual processing, but much remains unknown about its neural circuitry and vulnerability to disease. A major bottleneck has been our inability to observe the structure and function of the cells composing these retinal layers in the living human eye. Here, we present a noninvasive method to observe both structural and functional information. Adaptive optics optical coherence tomography (AO-OCT) is used to resolve the inner ...

    8. Measuring polarization changes in the human outer retina with polarization‐sensitive optical coherence tomography

      Measuring polarization changes in the human outer retina with polarization‐sensitive optical coherence tomography
      Morphological changes in the outer retina such as drusen are established biomarkers to diagnose age‐related macular degeneration. However, earlier diagnosis might be possible by taking advantage of more subtle changes that accompany tissues that bear polarization‐altering properties. To test this hypothesis, we developed a method based on polarization‐sensitive optical coherence tomography with which volumetric data sets of the macula were obtained from 10 young (25years) and 10 ...

      Imaging and quantifying ganglion cells and other transparent neurons in the living human retina [Engineering]
      Ganglion cells (GCs) are fundamental to retinal neural circuitry, processing photoreceptor signals for transmission to the brain via their axons. However, much remains unknown about their role in vision and their vulnerability to disease leading to blindness. A major bottleneck has been our inability to observe GCs and their degeneration in the living human eye. Despite two decades of development of optical technologies to image cells in the living human ...

      OPTICAL PROPERTIES OF PHOTORECEPTOR AND RETINAL PIGMENT EPITHELIUM CELLS INVESTIGATED WITH ADAPTIVE OPTICS OPTICAL COHERENCE TOMOGRAPHY (Thesis)
      Human vision starts when photoreceptors collect and respond to light. Photoreceptors do not function in isolation though, but share close interdependence with neighboring photoreceptors and underlying retinal pigment epithelium (RPE) cells. These cellular interactions are essential for normal function of the photoreceptor-RPE complex, but methods to assess these in the living human eye are limited. One approach that has gained increased promise is highresolution retinal imaging that has undergone tremendous ...

      Tracking dynamics of photoreceptor disc shedding with adaptive optics-optical coherence tomography
      Absorption of light by photoreceptors initiates vision, but also leads to accumulation of toxic photo-oxidative compounds in the photoreceptor outer segment (OS). To prevent this buildup, small packets of OS discs are periodically pruned from the distal end of the OS, a process called disc shedding. Unfortunately dysfunction in any part of the shedding event can lead to photoreceptor and RPE dystrophy, and has been implicated in numerous retinal diseases ...

      Evaluation of intraretinal migration of retinal pigment epithelial cells with Jones matrix optical coherence tomography
      We evaluated intraretinal RPE migration in AMD using multimodal imaging including polarimetric images. Depolarized light images were computed using a PS-SLO. M-DOPU was calculated using multifunctional Jones-matrix OCT. RPE migration was detected in 59 of 155 eyes. Focal similarities could be confirmed among en-face projection images of minimum M-DOPU, depolarized light images, and NIR-AF images.
