    2. En Face Imaging of Geographic Atrophy Using Different Swept-Source Optical Coherence Tomography Scan Patterns

      En Face Imaging of Geographic Atrophy Using Different Swept-Source Optical Coherence Tomography Scan Patterns
      Purpose Different swept source optical coherence tomography (SS-OCT) scan patterns were used to image geographic atrophy (GA) to determine if they provided similar area and enlargement measurements in eyes with age-related macular degeneration (AMD). Design Prospective, observational case series. Participants Patients with GA secondary to non-exudative AMD Methods Patients were imaged using SS-OCT (PLEX Elite 9000 instrument, Carl Zeiss Meditec, Dublin, CA) with follow-up imaging performed after six months and ...

    3. Swept-Source OCT Angiography Identifies Choroidal Neovascularization Arising From a Choroidal Nevus

      Swept-Source OCT Angiography Identifies Choroidal Neovascularization Arising From a Choroidal Nevus
      Swept-source optical coherence tomography angiography (SS-OCTA) was used to diagnose choroidal neovascularization (CNV) arising from a choroidal nevus. A 61-year-old woman initially presented with submacular hemorrhage. She was diagnosed with neovascular age-related macular degeneration (AMD) and received three injections of bevacizumab (Avastin; Genentech, South San Francisco, CA). At a follow-up visit, SS-OCTA showed that the CNV appeared to arise from an adjacent choroidal nevus. This is the first report of ...

    4. Swept-Source OCT Angiographic Imaging of a Central Retinal Vein Occlusion During Pregnancy

      Swept-Source OCT Angiographic Imaging of a Central Retinal Vein Occlusion During Pregnancy
      To avoid fluorescein angiography in a pregnant woman diagnosed with a central retinal vein occlusion (CRVO), swept-source optical coherence tomography angiography (SS-OCTA) was performed and showed no evidence of decreased central retinal perfusion leading to the diagnosis of a nonischemic CRVO. Five months after an intravitreal injection of steroid, both her vision and the retinal appearance had returned to normal. This case demonstrates how a noninvasive, safe, 12 mm 12 ...

    5. Detection of Choriocapillaris Loss in Alport Syndrome With Swept-Source OCT Angiography

      Detection of Choriocapillaris Loss in Alport Syndrome With Swept-Source OCT Angiography
      A patient previously diagnosed with Alport Syndrome was evaluated using multimodal imaging. Optical coherence tomography (OCT) demonstrated significant thinning of the inner retina within the macula, and inner retinal cysts were found in the peripheral macula. OCT angiography demonstrated loss of the choriocapillaris. Abnormal collagen appears to have multiple deleterious effects on the retinal and choroidal structure and vasculature.

    6. Swept-Source OCT Angiography of Multiple Evanescent White Dot Syndrome With Inflammatory Retinal Pigment Epithelial Detachment

      Swept-Source OCT Angiography of Multiple Evanescent White Dot Syndrome With Inflammatory Retinal Pigment Epithelial Detachment
      A 30-year-old woman with photopsias and decreased vision was diagnosed with multiple evanescent white dot syndrome (MEWDS) with an atypical inflammatory subfoveal retinal pigment epithelial detachment (PED) and imaged using swept-source optical coherence tomography (SS-OCT) during several visits. SS-OCT imaging revealed a focal area of attenuated choriocapillaris underneath the PED. An attempt to treat the presumed macular inflammatory lesion with corticosteroids resulted in bilateral exudation consistent with central serous chorioretinopathy.

      Estimating Public and Patient Savings From Basic Research—A Study of Optical Coherence Tomography in Managing Antiangiogenic Therapy
      Purpose To compare patient and Medicare savings from the use of optical coherence tomography (OCT) in guiding therapy for neovascular age-related macular degeneration (nvAMD) to the research investments made in developing OCT by the National Institutes of Health (NIH) and the National Science Foundation (NSF). Design Observational cohort study. Methods Main outcome measures were spending by Medicare as tracked by Current Procedural Terminology codes on intravitreal injections (67028), retinal OCT ...

      Optical coherence tomography angiography: A comprehensive review of current methods and clinical applications
      OCT has revolutionized the practice of ophthalmology over the past 1020 years. Advances in OCT technology have allowed for the creation of novel OCT-based methods. OCT-Angiography (OCTA) is one such method that has rapidly gained clinical acceptance since it was approved by the FDA in late 2016. OCTA images are based on the variable backscattering of light from the vascular and neurosensory tissue in the retina. Since the intensity and ...

    10. Comparison Between Spectral-Domain and Swept-Source Optical Coherence Tomography Angiographic Imaging of Choroidal Neovascularization

      Comparison Between Spectral-Domain and Swept-Source Optical Coherence Tomography Angiographic Imaging of Choroidal Neovascularization
      Purpose : The purpose of this study was to compare imaging of choroidal neovascularization (CNV) using swept-source (SS) and spectral-domain (SD) optical coherence tomography angiography (OCTA). Methods : Optical coherence tomography angiography was performed using a 100-kHz SS-OCT instrument and a 68-kHz SD-OCTA instrument (Carl Zeiss Meditec, Inc.). Both 3 3- and 6 6-mm 2 scans were obtained on both instruments. The 3 3-mm 2 SS-OCTA scans consisted of 300 A-scans per ...

      Choroidal Thickness and Choroidal Vessel Density in Nonexudative Age-Related Macular Degeneration Using Swept-Source Optical Coherence Tomography Imaging
      Purpose : To analyze the relationship between choroidal thickness and the distribution of choroidal blood vessels in eyes with nonexudative AMD. Methods : Eyes with a diagnosis of nonexudative AMD were imaged using a prototype 100-kHz swept-source (SS) optical coherence tomography (OCT) instrument (Carl Zeiss Meditec, Dublin, CA, USA) with a central wavelength of 1050 nm. We used an OCT cube scan pattern consisting of 512 512 A-scans over a 12 12 ...
