    3. Optical Coherence Tomography in Urologic Oncology: a Comprehensive Review

      Optical Coherence Tomography in Urologic Oncology: a Comprehensive Review
      Introduction Optical coherence tomography (OCT) is being investigated in urologic oncology for optical diagnosis. This comprehensive review analyzes the current state of development of OCT for bladder, upper urinary tract, kidney, prostate, testis, and penis cancer. Also, the potential role of OCT with regard to the current diagnostic pathways is critically appraised to guide future developments. Methods Embase and Pubmed were systematically searched for English and German articles on OCT ...

    4. Imaging Of Pigment Epithelial Detachments With Optical Coherence Tomography Angiography

      Imaging Of Pigment Epithelial Detachments With Optical Coherence Tomography Angiography
      Purpose: To investigate the utility of optical coherence tomography angiography (OCTA) for detecting pathologic vascularization within pigment epithelial detachments (PEDs). Methods: This was a retrospective, cross-sectional, consecutive case series. Multimodal imaging (structural OCT, fluorescein, and indocyanine green angiography) was used as the gold standard to classify PEDs as nonvascularized or vascularized. Optical coherence tomography angiography imaging of the PED was subsequently and independently evaluated to classify PEDs as vascularized or ...

      PROGRESSION OF MACULAR ATROPHY IN EYES WITH TYPE 1 NEOVASCULARIZATION AND AGE-RELATED MACULAR DEGENERATION RECEIVING LONG-TERM INTRAVITREAL ANTI–VASCULAR ENDOTHELIAL GROWTH FACTOR THERAPY: An Optical Coherence Tomographic Angiography Analysis
      Purpose: To evaluate the size and location of macular atrophy in eyes with Type-1 neovascularization (NV) and age-related macular degeneration receiving chronic intravitreal antivascular endothelial growth factor therapy. Methods: A retrospective review of a case series of 27 eyes with Type-1 NV and retinal pigment epithelial detachment (PED) having a minimum of 12 months follow-up was performed. Demographic information and visual acuity at baseline and the final follow-up were collected ...

    6. Quantitative shadow compensated optical coherence tomography of choroidal vasculature

      Quantitative shadow compensated optical coherence tomography of choroidal vasculature
      Conventionally rendered optical coherence tomography (OCT) images of the posterior segment contain shadows which influence the visualization of deep structures such as the choroid. The purpose of this study was to determine whether OCT shadow compensation (SC) alters the appearance of the choroid and the apparent choroidal vascularity index (CVI), an OCT-derived estimated ratio of luminal to total choroidal volume. All scans were shadow compensated using a previously published algorithm ...

    7. Dense B-scan Optical Coherence Tomography Angiography

      Dense B-scan Optical Coherence Tomography Angiography
      Purpose To describe a novel imaging technique, we call dense B-scan optical coherence tomography angiography (DB OCTA) in which thin dense raster scans are used to produce highly resolved structural B-scans with superimposed flow signal that provide precise correlation between retinal microstructure and blood flow. Design Observational case series Methods Normal eyes and eyes with macular findings of interest were imaged with DB OCTA in which 150-400 OCT B-scans were ...

    8. Directional Changes In Tissue Reflectivity May Influence Flow Detection On Optical Coherence Tomography Angiography

      Directional Changes In Tissue Reflectivity May Influence Flow Detection On Optical Coherence Tomography Angiography
      Purpose: To determine if directional or anatomical changes in tissue reflectivity of Henle fiber layer (HFL) may influence flow detection on optical coherence tomography angiography ( OCT-A ). Methods: Cross-sectional analysis of consecutive cases undergoing OCT-A . Directional changes in visualization of HFL were either produced manually by moving the beam entrance within the pupil or observed occurring naturally because of tilting of the OCT line-scan within a myopic staphyloma. Areas of enhanced ...

    9. Type 3 neovascularisation: long-term analysis of visual acuity and optical coherence tomography anatomical outcomes

      Type 3 neovascularisation: long-term analysis of visual acuity and optical coherence tomography anatomical outcomes
      Background To investigate the long-term visual and optical coherence tomography (OCT) anatomical outcomes of type 3 neovascularisation (NV) and to identify any baseline predictors of poor outcomes. Methods In this retrospective study, patients diagnosed with treatment nave type 3 NV were identified and categorised into two groups: good or poor vision based on final vision at 1year. Baseline demographic features and visual acuity (VA) and baseline and 1-year spectral domain ...

      SILDENAFIL CITRATE INDUCED RETINAL TOXICITY—ELECTRORETINOGRAM, OPTICAL COHERENCE TOMOGRAPHY, AND ADAPTIVE OPTICS FINDINGS
      Background/Purpose: To report a case of persistent retinal toxicity associated with a high dose of sildenafil citrate intake. Methods: Single retrospective case report. Results: A 31-year-old white man with no medical history presented with complaints of bilateral multicolored photopsias and erythropsia (red-tinted vision), shortly after taking sildenafil citratepurchased through the internet. Patient was found to have cone photoreceptor damage, demonstrated using electroretinogram, optical coherence tomography, and adaptive optics imaging ...

      Purpose To use the capillary-free zone along retinal arteries, a physiologic area of superficial avascularization, as an anatomic paradigm to investigate the reliability of optical coherence tomographic angiography (OCTA) for visualizing the deep retinal circulation. Design Validity analysis and laboratory investigation. Methods Five normal human donor eyes (mean age 69.8 years) were perfusion-labelled with endothelial antibodies and the capillary networks of the perifovea were visualized using confocal scanning laser ...

      INNER CHOROIDAL FLOW SIGNAL ATTENUATION IN PACHYCHOROID DISEASE: Optical Coherence Tomography Angiography
      Purpose: To study zones of reduced inner choroidal flow signal, foci of reduced inner choroidal thickness, and pathologically dilated Haller layer vessels (pachyvessels) in eyes with pachychoroid disease using optical coherence tomography (OCT) and OCT angiography. Methods: Patients with treatment-naive pachychoroid disease were recruited. All patients prospectively underwent swept-source OCT and OCT angiography. Zones of reduced choriocapillaris flow were labeled and enumerated. Areas where reduced flow signal was attributable to ...

    13. OPTICAL COHERENCE TOMOGRAPHY AND HISTOLOGY OF AGE-RELATED MACULAR DEGENERATION SUPPORT MITOCHONDRIA AS REFLECTIVITY SOURCES

      OPTICAL COHERENCE TOMOGRAPHY AND HISTOLOGY OF AGE-RELATED MACULAR DEGENERATION SUPPORT MITOCHONDRIA AS REFLECTIVITY SOURCES
      Purpose: Widespread adoption of optical coherence tomography has revolutionized the diagnosis and management of retinal disease. If the cellular and subcellular sources of reflectivity in optical coherence tomography can be identified, the value of this technology will be advanced even further toward precision medicine, mechanistic thinking, and molecular discovery. Four hyperreflective outer retinal bands are created by the exquisite arrangement of photoreceptors, Mller cells, retinal pigment epithelium, and Bruch membrane ...
