    2. PIPE-Net: A pyramidal-input-parallel-encoding network for the segmentation of corneal layer interfaces in OCT images

      PIPE-Net: A pyramidal-input-parallel-encoding network for the segmentation of corneal layer interfaces in OCT images
      Segmentation of corneal layer interfaces in optical coherence tomography (OCT) images is necessary to generate thickness maps used for cornea diagnosis. In this paper, we propose PIPE-Net, a fully convolutional neural network with a pyramidal input, parallel encoders, and a densely connected decoder to segment four corneal layer interfaces. The pyramidal input is encoded using parallel encoders, which allows the network to process a larger receptive field. The encoders are ...

    3. Effect of OCT B-scan density on sensitivity for detection of intraretinal hyperreflective foci in eyes with age-related macular degeneration

      Effect of OCT B-scan density on sensitivity for detection of intraretinal hyperreflective foci in eyes with age-related macular degeneration
      Purpose To evaluate the impact of reducing the density of B-scans in an optical coherence tomography (OCT) volume on the sensitivity for detecting intraretinal hyperreflective foci (IHRF) in eyes with intermediate age-related macular degeneration (AMD) Methods A total of 165 eyes with intermediate AMD and IHRF were evaluated in this retrospective analysis. For each case, Cirrus HD-OCT volumes were imported into the reading center 3D-OCTOR software. The number of IHRF ...

    4. Mitigating the effects of choroidal hyper- and hypo-transmission defects on choroidal vascularity index assessments using optical coherence tomography

      Mitigating the effects of choroidal hyper- and hypo-transmission defects on choroidal vascularity index assessments using optical coherence tomography
      Background: Changes in choroidal vascularity index (CVI) are associated with multiple choroid-related ocular diseases. CVI is calculated as the area/volume ratio of vessels in the choroid, which could be affected by alterations in regional signal intensities due to hypo-transmission defects (hypoTDs) caused by drusen and retinal pigment epithelium (RPE) detachments, and hyper-transmission defects (hyperTDs) caused by the absence of RPE. To develop a simulation model to verify the CVI ...

    5. Swept-Source Optical Coherence Tomography Detection of Bruch’s Membrane and Choriocapillaris Abnormalities in Sorsby Macular Dystrophy

      Swept-Source Optical Coherence Tomography Detection of Bruch’s Membrane and Choriocapillaris Abnormalities in Sorsby Macular Dystrophy
      Purpose: Swept-source optical coherence tomography angiography (SS-OCTA) was used to analyze Bruch's membrane (BM) and choriocapillaris (CC) abnormalities in undiagnosed family members with Sorsby macular dystrophy (SMD). Methods: In a family with SMD (TIMP3 Tyr191Cys), SS-OCTA imaging was performed using the 6X6mm scan patter and previously validated algorithms to detect abnormalities in BM and the CC, as well as the presence of reticular pseudodrusen (RPD) and macular neovascularization (MNV ...

    6. Optical Coherence Tomography Angiography Findings in Sclerochoroidal Calcification

      Optical Coherence Tomography Angiography Findings in Sclerochoroidal Calcification
      Optical coherence tomography angiography (OCT-A) is a modern non invasive imaging technique that may aid in the evaluation of retinal diseases through the assessment of chorioretinal vasculature. The literature regarding OCT-A in sclerochoroidal calcification is scarce. We present the case of a 57-year-old female who was referred to the clinic due to an atypical choroidal lesion in the right eye. OCT-A showed an apparent decrease in the vascular flow of ...

    7. Automatic geographic atrophy segmentation using optical attenuation in OCT scans with deep learning

      Automatic geographic atrophy segmentation using optical attenuation in OCT scans with deep learning
      A deep learning algorithm was developed to automatically identify, segment, and quantify geographic atrophy (GA) based on optical attenuation coefficients (OACs) calculated from optical coherence tomography (OCT) datasets. Normal eyes and eyes with GA secondary to age-related macular degeneration were imaged with swept-source OCT using 66 mm scanning patterns. OACs calculated from OCT scans were used to generate customized composite en face OAC images. GA lesions were identified and measured ...

    8. Optical coherence tomography angiography in the evaluation of vascular patterns of ocular surface squamous neoplasia during topical medical treatment

      Optical coherence tomography angiography in the evaluation of vascular patterns of ocular surface squamous neoplasia during topical medical treatment
      Purpose: Optical coherence tomography angiography (OCTA) was utilized to examine changes in ocular surface squamous neoplasia (OSSN) vascular patterns over time in individuals treated with topical medical therapy. Methods: Ten individuals with OSSN diagnosed by clinical examination and high resolution (HR)-optical coherence tomography (OCT) were recruited. All individuals received topical immuno- or chemotherapy. OCTA images were obtained and analyzed at three points: presentation, mid-treatment and tumor resolution. Tumor metrics ...

    9. The use of high resolution optical coherence tomography (HR-OCT) in the diagnosis of ocular surface masqueraders

      The use of high resolution optical coherence tomography (HR-OCT) in the diagnosis of ocular surface masqueraders
      Introduction: Ocular surface masqueraders encompass any ocular surface lesion masquerading as another ocular surface lesion. High resolution optical coherence tomography (HR-OCT) has emerged as an adjunctive tool to clinical acumen. This study's purpose is to evaluate the utility of HR-OCT images in guiding the diagnosis and management of those lesions. Material and methods: 22 individuals with a clinically ambiguous ocular surface lesion with slit lamp photographs (SLP), HR-OCT images ...

    10. Line-Field Confocal Optical Coherence Tomography Increases the Diagnostic Accuracy and Confidence for Basal Cell Carcinoma in Equivocal Lesions: A Prospective Study

      Line-Field Confocal Optical Coherence Tomography Increases the Diagnostic Accuracy and Confidence for Basal Cell Carcinoma in Equivocal Lesions: A Prospective Study
      Diagnosing clinically unclear basal cell carcinomas (BCCs) can be challenging. Line-field confocal optical coherence tomography (LC-OCT) is able to display morphological features of BCC subtypes with good histological correlation. The aim of this study was to investigate the accuracy of LC-OCT in diagnosing clinically unsure cases of BCC compared to dermoscopy alone and in distinguishing between superficial BCCs and other BCC subtypes. Moreover, we addressed pitfalls in false positive cases ...

    11. Advanced retinal imaging and applications for clinical practice: A consensus review

      Advanced retinal imaging and applications for clinical practice: A consensus review
      Imaging is an integral part of the evaluation and management of retinal disorders. Each imaging modality has its own unique capabilities and can show a different aspect or perspective of disease. Multimodal retinal imaging provides a wealth of substantive and insightful information; however, the integration of all this complex data can be overwhelming. We discuss the applications and the strengths and limitations of the many different retinal imaging tools that ...

    12. Laser-induced choroidal neovascularization detected on optical coherence tomography angiography in patients with diabetic retinopathy

      Laser-induced choroidal neovascularization detected on optical coherence tomography angiography in patients with diabetic retinopathy
      Purpose To report two cases of laser-induced choroidal neovascularization (CNV) using swept source optical coherence tomography (SS-OCTA) imaging in patients with proliferative diabetic retinopathy. Observations Two patients developed CNV adjacent to laser scars, and these neovascular lesions were detected on SS-OCTA imaging. Historically, both patients had subretinal fluid associated with these lesions. Visual acuity for both patients was 20/25 in the affected eyes. Both patients were observed over multiple ...
