    2. Lid-parallel conjunctival fold (LIPCOF) morphology imaged by optical coherence tomography and its relationship to LIPCOF grade

      Lid-parallel conjunctival fold (LIPCOF) morphology imaged by optical coherence tomography and its relationship to LIPCOF grade
      Purpose Lid-parallel conjunctival folds (LIPCOF) are a well-accepted clinical sign in dry eye diagnosis. Commonly, LIPCOF is classified by grading the number of folds observed by slit-lamp microscope. This study investigated the relationship between subjective grading scale and LIPCOF morphology imaged by optical coherence tomography (OCT). Methods Temporal and nasal LIPCOF of 42 subjects (mean age 27.38.4 (SD) years; 13M, 29F) were observed and classified by an experienced ...

    4. Adaptive-Weighted Bilateral Filtering and Other Pre-processing Techniques for Optical Coherence Tomography

      Adaptive-Weighted Bilateral Filtering and Other Pre-processing Techniques for Optical Coherence Tomography
      This paper presents novel pre-processing image enhancement algorithms for retinal optical coherence tomography (OCT). These images contain a large amount of speckle causing them to be grainy and of very low contrast. To make these images valuable for clinical interpretation, we propose a novel method to remove speckle, while preserving useful information contained in each retinal layer. The process starts with multi-scale despeckling based on a dual-tree complex wavelet transform ...

    7. Graphics processing unit-based dispersion encoded full-range frequency-domain optical coherence tomography

      Graphics processing unit-based dispersion encoded full-range frequency-domain optical coherence tomography
      Dispersion encoded full-range (DEFR) frequency-domain optical coherence tomography (FD-OCT) and its enhanced version, fast DEFR, utilize dispersion mismatch between sample and reference arm to eliminate the ambiguity in OCT signals caused by non-complex valued spectral measurement, thereby numerically doubling the usable information content. By iteratively suppressing asymmetrically dispersed complex conjugate artifacts of OCT-signal pulses the complex valued signal can be recovered without additional measurements, thus doubling the spatial signal range ...

    8. Graphics processing unit based dispersion encoded full-range frequency domain OCT

      Graphics processing unit based dispersion encoded full-range frequency domain OCT
      Standard FD-OCT systems suffer from a limited useful depth range due to the inherent complex conjugate artifacts and continuous fall-off in sensitivity with distance from the zero delay. The techniques of dispersion encoded full range (DEFR) frequency-domain optical coherence tomography (FD-OCT) and its enhanced version fast DEFR use the dispersion mismatch between sample and reference arm to double the imaging depth range by iteratively suppressing complex conjugate artifacts. Previously the ...

    9. Automated choroidal segmentation of 1060 nm OCT in healthy and pathologic eyes using a statistical model

      Automated choroidal segmentation of 1060 nm OCT in healthy and pathologic eyes using a statistical model
      A two stage statistical model based on texture and shape for fully automatic choroidal segmentation of normal and pathologic eyes obtained by a 1060 nm optical coherence tomography (OCT) system is developed. A novel dynamic programming approach is implemented to determine location of the retinal pigment epithelium/ Bruch’s membrane /choriocapillaris (RBC) boundary. The choroid–sclera interface (CSI) is segmented using a statistical model. The algorithm is robust even in ...
