    2. Can deep learning improve the automatic segmentation of deep foveal avascular zone in optical coherence tomography angiography

      Can deep learning improve the automatic segmentation of deep foveal avascular zone in optical coherence tomography angiography
      Optical coherence tomography angiography (OCTA) is extensively used for visualizing retinal vasculature, including the foveal avascular zone (FAZ). Assessment of the FAZ is critical in the diagnosis and management of various retinal diseases. Accurately segmenting the FAZ in the deep retinal layer (dFAZ) is very challenging due to unclear capillary terminals. In this study, a customized encoder-decoder deep learning network was used for dFAZ segmentation. Six-fold cross-validation was performed on ...

    3. Near-infrared fundus autofluorescence alterations correlate with swept-source optical coherence tomography angiography findings in patients with retinitis pigmentosa

      Near-infrared fundus autofluorescence alterations correlate with swept-source optical coherence tomography angiography findings in patients with retinitis pigmentosa
      Thirty-eight patients from 37 families with retinitis pigmentosa (RP) underwent macular 6 6-mm swept-source optical coherence tomography angiography (SS-OCTA) and 30 near-infrared fundus autofluorescence (NIR-FAF) acquisitions in one eye. Superficial vascular complex (SVC), deep capillary complex (DCC) and choriocapillaris (CC) angiograms were registered with NIR-FAF acquisitions to comparatively assess subjects with and without central area of preserved NIR-FAF (APA). On the subset of patients showing an APA, the vessel densities ...

    4. Retinal applications of swept source optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA)

      Retinal applications of swept source optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA)
      The advent of optical coherence tomography (OCT) revolutionized both clinical assessment and research of vitreoretinal conditions. Since then, extraordinary advances have been made in this imaging technology, including the relatively recent development of swept-source OCT (SS-OCT). SS-OCT enables a fast scan rate and utilizes a tunable swept laser at longer wavelengths than conventional spectral-domain devices. These features enable imaging of larger areas with reduced motion artifact, and a better visualization ...

    6. Evaluation of the inner choroid using OCT angiography

      Evaluation of the inner choroid using OCT angiography
      The advent of optical coherence tomography angiography (OCTA) has allowed a qualitative and quantitative analysis of the retinal vasculature and the choriocapillaris. With the use of OCTA, several studies evaluated the changes in the choriocapillaris showing how this vascular structure plays a significant role in the pathogenesis of different conditions. This article reviews the current methods of analysis of the choriocapillaris and the relevant findings in different chorioretinal diseases.

    8. Cyst Detection and Motion Artifact Elimination in Enface Optical Coherence Tomography Angiograms

      Cyst Detection and Motion Artifact Elimination in Enface Optical Coherence Tomography Angiograms
      The correct detection of cysts in Optical Coherence Tomography Angiography images is of crucial importance for allowing reliable quantitative evaluation in patients with macular edema. However, this is a challenging task, since the commercially available software only allows manual cysts delineation. Moreover, even small eye movements can cause motion artifacts that are not always compensated by the commercial software. In this paper, we propose a novel algorithm based on the ...

      CHOROIDAL GRANULOMAS VISUALIZED BY SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY
      Purpose: To assess the visualization of choroidal granulomas with swept-source optical coherence tomography angiography (OCTA). Methods: Consecutive patients with granulomatous choroiditis due to tuberculosis, sarcoidosis, or VogtKoyanagiHarada disease underwent baseline OCTA images using a 12 12-mm field of view, and the choroidal slabs were analyzed by two independent examiners who counted the oval areas of flow void. Simultaneously, indocyanine green angiography (ICGA) and enhanced-depth imaging OCT were performed to mark ...

      Optical coherence tomography angiography for the measurement of optic disc: Macular relationship
      Introduction: Fundus photography is the gold standard for assessing ocular torsion over the last 30years. However, it is not a precise and reproducible tool during clinical practice. Optical coherence tomography angiography is characterized by precise identification of the macula and the optic disc, and it could be an effective method to easily calculate the angle of ocular torsion, compared to fundus photography. The aim of this study was to show ...
