    2. Coronary Stent Healing in Cancer Patients—An Optical Coherence Tomography Perspective

      Coronary Stent Healing in Cancer Patients—An Optical Coherence Tomography Perspective
      Objective: This study assessed stent healing patterns and cardiovascular outcomes by optical coherence tomography (OCT) in cancer patients after drug-eluting stent (DES) placement. Background: Cancer treatment, owing to its cytotoxic and antiproliferative effects, could delay stent healing and increase stent thrombosis risk, especially when dual antiplatelet therapy (DAPT) is discontinued early for oncological treatment. OCT can assess stent endothelialization and other healing parameters, which may provide clinical guidance in these ...

    3. Using Anterior Segment Optical Coherence Tomography (ASOCT) Parameters to Determine Pupillary Block versus Plateau Iris Configuration

      Using Anterior Segment Optical Coherence Tomography (ASOCT) Parameters to Determine Pupillary Block versus Plateau Iris Configuration
      Precis The potential parameters for differentiating pupillary block from plateau iris configuration on ASOCT are lens/pupil size parameters and angles. Further study is needed to determine a landmark peripheral to the centroid of the iris. Purpose: Investigate anterior segment parameters to distinguish between 2 mechanisms of angle closure : pupillary block (PB) and plateau iris configuration (PIC), using swept-source Fourier domain anterior segment optical coherence tomography (ASOCT) Patients and Methods ...

    5. Impact of Ticagrelor and Aspirin versus Clopidogrel and Aspirin in Symptomatic Patients with Peripheral Arterial Disease: Thrombus Burden Assessed by Optical Coherence Tomography

      Impact of Ticagrelor and Aspirin versus Clopidogrel and Aspirin in Symptomatic Patients with Peripheral Arterial Disease: Thrombus Burden Assessed by Optical Coherence Tomography
      Purpose To compare OCT identified white thrombus decline, neointimal hyperplasia and clinical outcomes of patients treated with ticagrelor plus aspirin with those patients treated with clopidogrel plus aspirin after peripheral interventions. Background Ticagrelor is a potent platelet inhibitor. In patients with coronary artery disease, ticagrelor and aspirin demonstrated reduced rates of stent thrombosis, compared to aspirin and clopidogrel. The clinical importance of potent antiplatelet inhibition after peripheral endovascular interventions is ...

    6. Agreement between Gonioscopic Examination and Swept Source Fourier Domain Anterior Segment Optical Coherence Tomography Imaging

      Agreement between Gonioscopic Examination and Swept Source Fourier Domain Anterior Segment Optical Coherence Tomography Imaging
      Purpose . To evaluate interobserver, intervisit, and interinstrument agreements for gonioscopy and Fourier domain anterior segment optical coherence tomography (FD ASOCT) for classifying open and narrow angle eyes. Methods . Eighty-six eyes with open or narrow anterior chamber angles were included. The superior angle was classified open or narrow by 2 of 5 glaucoma specialists using gonioscopy and imaged by FD ASOCT in the dark. The superior angle of each FD ASOCT ...

    7. Diagnosis of Thin-Capped Fibroatheromas in Intravascular Optical Coherence Tomography Images Effects of Light Scattering

      Diagnosis of Thin-Capped Fibroatheromas in Intravascular Optical Coherence Tomography Images Effects of Light Scattering
      Background Intravascular optical coherence tomography (IVOCT) images are recorded by detecting light backscattered within coronary arteries. We hypothesize that nonthin-capped fibroatheroma (TCFA) causes may scatter light to create the false appearance of IVOCT TCFA. Methods and Results Ten human cadaver hearts were imaged with IVOCT (n=14 coronary arteries). IVOCT and histological TCFA images were coregistered and compared. Of 21 IVOCT TCFAs (fibrous cap 65 m, lipid arc 1 quadrant ...

    8. Comparison of Newer IOL Power Calculation Methods for Eyes With Previous Radial Keratotomy

      Comparison of Newer IOL Power Calculation Methods for Eyes With Previous Radial Keratotomy
      Purpose : To evaluate the accuracy of the optical coherence tomographybased (OCT formula) and Barrett True K (True K) intraocular lens (IOL) calculation formulas in eyes with previous radial keratotomy (RK). Methods : In 95 eyes of 65 patients, using the actual refraction following cataract surgery as target refraction, the predicted IOL power for each method was calculated. The IOL prediction error (PE) was obtained by subtracting the predicted IOL power from ...

    10. Fourier optics analysis of phase-mask-based path-length-multiplexed optical coherence tomography

      Fourier optics analysis of phase-mask-based path-length-multiplexed optical coherence tomography
      Imaging below fingertip surface might be a useful alternative to the traditional fingerprint sensing since the internal finger features are more reliable than the external ones. One of the most promising subsurface imaging technique is optical coherence tomography (OCT), which, however, has to acquire 3-D data even when a single en face image is required. This makes OCT inherently slow for en face imaging and produce unnecessary large data sets ...
