    2. Glaucoma diagnosis using multi-feature analysis and a deep learning technique

      Glaucoma diagnosis using multi-feature analysis and a deep learning technique
      In this study, we aimed to facilitate the current diagnostic assessment of glaucoma by analyzing multiple features and introducing a new cross-sectional optic nerve head (ONH) feature from optical coherence tomography (OCT) images. The data (n=100 for both glaucoma and control) were collected based on structural, functional, demographic and risk factors. The features were statistically analyzed, and the most significant four features were used to train machine learning (ML ...

    3. Visualisation of peripheral retinal degenerations and anomalies with ocular imaging

      Visualisation of peripheral retinal degenerations and anomalies with ocular imaging
      Purpose Certain peripheral retinal degenerations pose a significant risk to vision and require prompt detection and management. Other historically benign peripheral lesions are being recognised as clinically significant due to their associations with ocular and systemic disorders. Assessment and documentation of these entities however can be difficult due to challenges in visualisation of the peripheral retina. This review addresses this by providing a series of clinical examples of these entities ...

    4. Evaluating Severity of Microbial Keratitis Using Optical Coherence Tomography

      Evaluating Severity of Microbial Keratitis Using Optical Coherence Tomography
      Microbial keratitis (MK) is an infection of the cornea caused a variety of pathogens that can lead to significant visual loss. The current diagnosis relies on clinical examination and microbiological testing. New in-vivo imaging techniques are now available that can assist the diagnosis and follow the clinical course of this disease. Using optical coherence tomography (OCT) it is possible to obtain high resolution imaging for the cornea. The purpose of ...

    5. Correlation of choriocapillaris hemodynamic data from dynamic indocyanine green and optical coherence tomography angiography

      Correlation of choriocapillaris hemodynamic data from dynamic indocyanine green and optical coherence tomography angiography
      To investigate the correlation between posterior pole choroidal blood flow evaluated with digital subtraction indocyanine green angiography and enface optical coherence tomography angiography (OCTA). Imaging in animal study. The anatomy of 2 cynomogulus monkeys was studied. Each monkey was given a 0.75 mg/kg injection of indocyanine green in the saphenous vein. The dynamic angiographic filling sequence was recorded at 15 frames per second using the Heidelberg Spectralis. After ...

    6. An en face swept source optical coherence tomography study of the vitreous in eyes with anterior uveitis

      An en face swept source optical coherence tomography study of the vitreous in eyes with anterior uveitis
      Purpose: To analyse vitreous anatomy patients with anterior uveitis (AU) using swept source optical coherence tomography (SS-OCT). Methods: Patients with newly diagnosed AU and healthy participants were scanned using 16-mm SS-OCT B-scans and 12 12 mm cube centred at the fovea. Linear SS-OCT scans were evaluated to identify the premacular bursa (PB) above the macula and the Cloquet's canal above the optic disc. A dynamic evaluation of the 12 ...

    7. Diagnostic accuracy of AS-OCT vs gonioscopy for detecting angle closure: a systematic review and meta-analysis

      Diagnostic accuracy of AS-OCT vs gonioscopy for detecting angle closure: a systematic review and meta-analysis
      Purpose: This study aims to review the literature that compares the accuracy of Anterior Segment-Optical Coherence Tomography (AS-OCT) against gonioscopy in detecting eyes with angle closure. It is currently unclear how AS-OCT fits into clinical practice for detecting angle closure. This is a systematic review and meta-analysis. Methods: A literature search was performed on Medline, Embase, Scopus and the Cochrane Central Register of Controlled Trials to identify studies that investigated ...

    8. Optical Coherence Tomography Angiography Findings of Iris Ischemia and Reperfusion in Cytomegalovirus Panuveitis

      Optical Coherence Tomography Angiography Findings of Iris Ischemia and Reperfusion in Cytomegalovirus Panuveitis
      Purpose : To report a case of iris ischemia in an eye affected by Cytomegalovirus (CMV)-related Chronic Retinal Necrosis (CRN) with partial reperfusion after antiviral therapy demonstrated by optical coherence tomography angiography (OCTA). Methods : Retrospective case report. Multimodal imaging was performed at each follow-up visits. Results : At baseline, the clinical findings and PCR on aqueous confirmed the diagnosis of CMV-induced CRN, while OCTA and Fluorescein Angiography showed multi-sectoral retinal and ...

    9. Differential reperfusion patterns in retinal vascular plexuses following increase in intraocular pressure an OCT angiography study

      Differential reperfusion patterns in retinal vascular plexuses following increase in intraocular pressure an OCT angiography study
      To describe patterns of reperfusion in the superficial vascular plexus (SVP), deep capillary plexus (DCP) and choriocapillaris (CC) as detected on optical coherence tomography (OCTA) in cynomogulus macaque monkey model following increase in intraocular pressure by an intravitreal injection. Animal imaging study. Two cynomogulus macaque monkeys. A 100 L intravitreal injection (IVI) of saline was given in one eye of each monkey. Serial OCTA using a Zeiss Plex Elite 9000 ...

    10. Optical coherence tomography angiography for detection of macular neovascularization associated with atrophy in age-related macular degeneration

      Optical coherence tomography angiography for detection of macular neovascularization associated with atrophy in age-related macular degeneration
      Purpose To evaluate the ability of optical coherence tomography angiography (OCTA) to detect macular neovascularization (MNV) in eyes with atrophy compared with fluorescein angiography (FA), indocyanine green angiography (ICGA), and optical coherence tomography (OCT). Methods In this prospective study, eyes with MNV and atrophy (termed macular atrophy or MA) secondary to age-related macular degeneration (AMD), and AMD eyes with geographic atrophy (GA) without MNV underwent multimodal imaging with FA, ICGA ...

    13. Wavelength-encoded multi-channel spectral-domain optical coherence tomography (SD-OCT) for spatiotemporally resolved imaging

      Wavelength-encoded multi-channel spectral-domain optical coherence tomography (SD-OCT) for spatiotemporally resolved imaging
      In conventional SD-OCT, a beam is focused to one spot on the surface of the sample to acquire depth information beneath that spot. Adjacent spots are serially scanned to obtain a tomographic image of the sample; thus, available OCT techniques can take significant time to scan large objects. This paper illustrates an SD-OCT system involving spectral-slicing of a broadband spectrum to enable the simultaneous acquisition from multiple lateral positions of ...
