    4. Impact of Binarization Thresholding and Brightness/Contrast Adjustment Methodology on Optical Coherence Tomography Angiography Image Quantification

      Impact of Binarization Thresholding and Brightness/Contrast Adjustment Methodology on Optical Coherence Tomography Angiography Image Quantification
      Purpose Binarization is a critical technique in OCTA image analysis, but there is no consistency in the method used in published OCTA studies. This study assessed whether differences in OCTA binarization and brightness/contrast adjustments affect quantification metrics. Design Prospective cross-sectional validity study Methods This was a single-center study examining 21 eyes of 11 healthy individuals. All eyes were imaged using the Carl Zeiss PLEX Elite 9000 swept source-OCTA, and ...

    5. Early hydroxychloroquine retinopathy: optical coherence tomography abnormalities preceding Humphrey visual field defects

      Early hydroxychloroquine retinopathy: optical coherence tomography abnormalities preceding Humphrey visual field defects
      Background/Aims Hydroxychloroquine (HCQ) retinopathy may result in severe and irreversible vision loss, emphasising the importance of screening and early detection. The purpose of this study is to report the novel finding of early optical coherence tomography (OCT) abnormalities due to HCQ toxicity that may develop in the setting of normal Humphrey visual field (HVF) testing. Methods Data from patients with chronic HCQ exposure was obtained from seven tertiary care ...

    7. QUANTIFICATION OF RETINAL CAPILLARY NONPERFUSION IN DIABETICS USING WIDE-FIELD OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY

      QUANTIFICATION OF RETINAL CAPILLARY NONPERFUSION IN DIABETICS USING WIDE-FIELD OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY
      Purpose: To combine advances in high-speed, wide-field optical coherence tomography angiography ( OCTA ) with image processing methods for semiautomatic quantitative analysis of capillary nonperfusion in patients with diabetic retinopathy (DR). Methods: Sixty-eight diabetic patients (73 eyes), either without retinopathy or with different degrees of retinopathy, were prospectively recruited for volumetric swept-source OCTA imaging using 12 mm 12 mm fields centered at the fovea. A custom, semiautomatic software algorithm was used to ...

    8. Application of Optical Coherence Tomography Angiography to Retinal Disease

      Application of Optical Coherence Tomography Angiography to Retinal Disease
      A little over two years ago, a hot new topic in retinal imaging caught the attention of ophthalmologists around the world. Optical coherence tomography angiography (OCTA), an innovative, fast, noninvasive, non-dye-based angiographic technique, quickly became a topic of great interest in major conferences and ophthalmology journals. Inquisitive minds applied the OCTA prototypes to understanding diseases such as macular degeneration, diabetic retinopathy, and glaucoma. The technologys high resolution and ability to ...

    9. VISUALIZATION OF CHOROIDAL NEOVASCULARIZATION USING TWO COMMERCIALLY AVAILABLE SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY DEVICES

      VISUALIZATION OF CHOROIDAL NEOVASCULARIZATION USING TWO COMMERCIALLY AVAILABLE SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY DEVICES
      Purpose: To compare the sensitivity of detection and the measured size of choroidal neovascularization ( CNV ) on two commercially available spectral domain optical coherence tomography angiography ( OCTA ) devices, the Optovue RTVue XR Avanti with AngioVue and the Zeiss Cirrus HD-OCT with AngioPlex. Methods: Patients with CNV lesions were imaged consecutively on both OCTA devices on the same day of their visit. 3 3 mm and 6 6 mm scans centered at ...

    10. A Joint Probabilistic Model for Speckle Variance, Amplitude Decorrelation and Interframe Variance (IFV) Optical Coherence Tomography Angiography

      A Joint Probabilistic Model for Speckle Variance, Amplitude Decorrelation and Interframe Variance (IFV) Optical Coherence Tomography Angiography
      Optical Coherence Tomography Angiography (OCTA) is a general method to visualize blood flow in biological tissue. Despite its good results in practice, the commonly used Amplitude Decorrelation OCTA (AD-OCTA) measure suffers from a well-understood objective function, which makes it challenging to mathematically model post processing tasks like, e.g., denoising. In this paper, a probabilistic model is developed for the three OCTA measures Speckle Variance OCTA, ADOCTA and the newly ...
