    2. The Effect of Different Optical Clearing Agents on the Attenuation Coefficient and Epidermal Thickness of Human Skin Assessed by Optical Coherence Tomography

      The Effect of Different Optical Clearing Agents on the Attenuation Coefficient and Epidermal Thickness of Human Skin Assessed by Optical Coherence Tomography
      Background : Optical coherence tomography (OCT) is a non-invasive imaging technique based on the interferometry of backscattered light. However, strong light scattering hinders its applicability in clinical dermatology. The strength of scattering is exemplified by the attenuation coefficient which is the rate of OCT signal decay in depth. Attenuation can be reduced by topical application of hyperosmotic liquids with a high refractive index, namely optical clearing agents (OCAs). In this study ...

    3. Macular microcirculation changes after macula-off rhegmatogenous retinal detachment repair with silicone oil tamponade evaluated by OCT-A: preliminary results

      Macular microcirculation changes after macula-off rhegmatogenous retinal detachment repair with silicone oil tamponade evaluated by OCT-A: preliminary results
      Background: Rhegmatogenous retinal detachment (RRD) with macular involvement is a sight-threatening condition. Silicone oil (SO) is efficacious for retinal tamponade, especially in complex cases. Whether macular detachment per se or the potential tamponading agent may affect macular microcirculation after RRD repair is a matter of research. Objectives: To investigate macular microcirculation changes using optical coherence tomography angiography (OCT-A) after pars plana vitrectomy (PPV) with intravitreal SO for RRD repair in ...

    4. Retinal microcirculation characteristics in obstructive sleep apnea/hypopnea syndrome evaluated by OCT-angiography: a literature review

      Retinal microcirculation characteristics in obstructive sleep apnea/hypopnea syndrome evaluated by OCT-angiography: a literature review
      Purpose: The retina may provide a window to estimate systemic vascular status; therefore, there has been interest in identifying microcirculation characteristics that possibly reflect hypoxic alterations in obstructive sleep apnea/hypopnea syndrome (OSAS). Emerging evidence has suggested that retinal microvasculature investigation holds the potential to characterize the pathophysiology involved in ocular manifestations of OSAS. The advent of optical coherence tomography angiography (OCT-A) has attracted significant attention as this technique offers ...

    5. Optical coherence tomography in coronary atherosclerosis assessment and intervention

      Optical coherence tomography in coronary atherosclerosis assessment and intervention
      Since optical coherence tomography (OCT) was first performed in humans two decades ago, this imaging modality has been widely adopted in research on coronary atherosclerosis and adopted clinically for the optimization of percutaneous coronary intervention. In the past 10 years, substantial advances have been made in the understanding of in vivo vascular biology using OCT. Identification by OCT of culprit plaque pathology could potentially lead to a major shift in ...

    6. Evaluation of the choriocapillaris after photodynamic therapy for chronic central serous chorioretinopathy. A review of optical coherence tomography angiography (OCT-A) studies

      Evaluation of the choriocapillaris after photodynamic therapy for chronic central serous chorioretinopathy. A review of optical coherence tomography angiography (OCT-A) studies
      Purpose: Emerging evidence suggests that choroidal microcirculation and microstructural changes after verteporfin photodynamic therapy (vPDT) for chronic central serous chorioretinopathy (CSC) can be shown in detail using OCT-Angiography (OCT-A). The use of OCT-A for the examination of choriocapillaris (CC) has attracted significant attention as the technique offers potential explanations for the effects of vPDT on choroidal tissue. Methods: A meticulous literature search was performed in the PubMed database without restriction ...

    8. Sensitivity of spectral domain optical coherence tomography in the diagnosis of posterior vitreous detachment in vitreomacular interface disorders: A prospective cohort study

      Sensitivity of spectral domain optical coherence tomography in the diagnosis of posterior vitreous detachment in vitreomacular interface disorders: A prospective cohort study
      Purpose: To evaluate the sensitivity of Spectral Domain Optical Coherence Tomography (SD-OCT) regarding the diagnosis of posterior vitreous detachment (PVD) in vitreomacular interface disorders (VID). Methods: A total of 48 eyes of 48 patients were included in this prospective cohort study. PVD in eyes with VID was investigated. We determined the status of posterior vitreous cortex using slit lamp (SL) biomicroscopy and SD-OCT preoperatively, during vitrectomy and on the intraoperative ...

    9. Association of OCT-A characteristics with postoperative visual acuity after rhegmatogenous retinal detachment surgery: a review of the literature

      Association of OCT-A characteristics with postoperative visual acuity after rhegmatogenous retinal detachment surgery: a review of the literature
      Purpose: Emerging evidence has suggested that macular microcirculation and microstructural changes after rhegmatogenous retinal detachment (RRD) successful reattachment surgery are currently evaluated in detail by OCT-Angiography (OCT-A). New imaging technology has revealed the existence of microscopic macular changes, even in cases that retinal morphology appears to be normal in fundus biomicroscopy. The use of OCT-A for the examination of foveal characteristics has attracted significant attention in recent years as the ...

    10. Optical Coherence Tomography Facilitating Early Withdrawal of Antiplatelet Agents in a High–Bleeding Risk Patient

      Optical Coherence Tomography Facilitating Early Withdrawal of Antiplatelet Agents in a High–Bleeding Risk Patient
      Optical coherence tomography (OCT) can guide percutaneous coronary interventions to optimize results, thus minimizing the risk of stent thrombosis. We present the case of a cancer patient, paroxysmal atrial fibrillation, and unstable angina who underwent OCTguided complex percutaneous coronary intervention and who required early discontinuation of antiplatelet therapy because of major bleeding.

    11. Utility of Multimodality Intravascular Imaging and the Local Hemodynamic Forces to Predict Atherosclerotic Disease Progression

      Utility of Multimodality Intravascular Imaging and the Local Hemodynamic Forces to Predict Atherosclerotic Disease Progression
      Objectives This study sought to examine the utility of multimodality intravascular imaging and of the endothelial shear stress (ESS) distribution to predict atherosclerotic evolution. Background There is robust evidence that intravascular ultrasound (IVUS)-derived plaque characteristics and ESS distribution can predict, with however limited accuracy, atherosclerotic evolution; nevertheless, it is yet unclear whether multimodality imaging and ESS mapping enable more accurate prediction of coronary plaque progression. Methods A total of ...

      A Case Series of Bowen’s Disease Treated with the Combination of Cryosurgery and Ingenol Mebutate and Followed Up with Optical Coherence Tomography
      Bowens disease (BD) is a relatively rare in situ squamous cell carcinoma (SCC) with a limited potential of becoming invasive. Ingenol mebutate (IM) was relatively successful for the treatment of BD lesions in small case series. Optical coherence tomography (OCT) is a promising method for the diagnosis of cutaneous keratinocytic carcinomas, including BD. Herein we report the treatment of BD with the combination of cryosurgery and IM and the application ...

    14. Basic interpretation of intracoronary ultrasound and optical coherence tomography images: examples

      Basic interpretation of intracoronary ultrasound and optical coherence tomography images: examples
      Latest advancements in intracoronary imaging have enabled the insertion of miniaturized catheters with imaging probes in coronary arteries in order to provide detailed imaging information in a cross-sectional image format after an automated pullback. Cross-sectional images can then be also used for longitudinal reconstructions for the vessel segment imaged. There are two main broadly available intracoronary imaging modalities, namely intravascular ultrasound (IVUS) and optical coherence tomography (OCT), which provide information ...
