      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 ...

      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 ...

      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 ...

      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 ...
