      Fully Automated Segmentation of Hyperreflective Foci in Optical Coherence Tomography Images
      The automatic detection of disease related entities in retinal imaging data is relevant for disease- and treatment monitoring. It enables the quantitative assessment of large amounts of data and the corresponding study of disease characteristics. The presence of hyperreflective foci (HRF) is related to disease progression in various retinal diseases. Manual identification of HRF in spectral-domain optical coherence tomography (SD-OCT) scans is error-prone and tedious. We present a fully automated ...

      Compact akinetic swept source optical coherence tomography angiography at 1060 nm supporting a wide field of view and adaptive optics imaging modes of the posterior eye
      Imaging of the human retina with high resolution is an essential step towards improved diagnosis and treatment control. In this paper, we introduce a compact, clinically user-friendly instrument based on swept source optical coherence tomography (SS-OCT). A key feature of the system is the realization of two different operation modes. The first operation mode is similar to conventional OCT imaging and provides large field of view (FoV) images (up to ...

      Large field of view adaptive optics scanning laser ophthalmoscopy and optical coherence tomography
      Adaptive Optics (AO) retinal imaging is revealing microscopic structures of the eye in a non-invasive way. Due to anisoplanatism, conventional AO systems are efficient on small 1x1 field of view (FoV). We present a lens-based AO scanning laser ophthalmoscope (SLO) set-up with 2 deformable mirrors (DM), providing high-resolution retinal imaging on a 4x4 FoV, for an eye pupil diameter of 7 mm. The first DM is in a pupil plane ...

      White light polarization sensitive optical coherence tomography for sub-micron axial resolution and spectroscopic contrast in the murine retina
      A white light polarization sensitive optical coherence tomography system has been developed, using a supercontinuum laser as the light source. By detecting backscattered light from 400700 nm, an axial resolution of 1.0 m in air was achieved. The system consists of a free-space interferometer and two homemade spectrometers that detect orthogonal polarization states. Following system specifications, images of a healthy murine retina as acquired by this non-contact system are ...

      Visualization of neuritic plaques in Alzheimer’s disease by polarization-sensitive optical coherence microscopy
      One major hallmark of Alzheimers disease (AD) and cerebral amyloid angiopathy (CAA) is the deposition of extracellular senile plaques and vessel wall deposits composed of amyloid-beta (A ). In AD, degeneration of neurons is preceded by the formation of A plaques, which show different morphological forms. Most of them are birefringent owing to the parallel arrangement of amyloid fibrils. Here, we present polarization sensitive optical coherence microscopy (PS-OCM) for imaging mature ...

      Ocular fundus pulsations within the posterior rat eye: Chorioscleral motion and response to elevated intraocular pressure
      A multi-functional optical coherence tomography (OCT) approach is presented to determine ocular fundus pulsations as an axial displacement between the retina and the chorioscleral complex in the albino rat eye. By combining optical coherence elastography and OCT angiography (OCTA), we measure subtle deformations in the nanometer range within the eye and simultaneously map retinal and choroidal perfusion. The conventional OCT reflectivity contrast serves as a backbone to segment the retina ...

      Polarization-sensitive optical coherence tomography in the anterior mouse eye
      Polarization-sensitive optical coherence tomography (PS-OCT) provides intrinsic contrast related to tissue microstructure. In the past, PS-OCT has been successfully used for imaging the anterior eye of humans in a variety of pathologic conditions. Here, we present PS-OCT imaging of the anterior eye in mice. Spectral domain PS-OCT centered at a wavelength of 840 nm was performed in anaesthetized laboratory mice. Three dimensional data sets were acquired at a 70 kHz ...

      Ultrahigh-resolution Optical Coherence Tomography Imaging of the Anterior Eye Segment Structures
      The development of optical coherence tomography (OCT) and its application for in vivo imaging has opened entirely new opportunities in ophthalmology (Wojtkowski, Kaluzny et al. 2012; Drexler, Liu et al. 2014). The technology allows for both noninvasive visualization of the morphology and measurement of functional parameters within ocular tissues to a depth of a few millimetres even in nontransparent media. Until now the resolution of commercially available OCT systems is ...
