    2. Diagnosing Choroidal Neovascularization in Asymptomatic Individuals Using Optical Coherence Tomography Angiography

      Diagnosing Choroidal Neovascularization in Asymptomatic Individuals Using Optical Coherence Tomography Angiography
      Optical coherence tomography angiography (OCTA) is a noninvasive, rapid imaging technique that generates angiographic images without intravenous dye injections. Cross-sectional studies have described the presence of asymptomatic choroidal neovascularization (CNV) in patients with intermediate age-related macular degeneration (AMD). This case report describes the OCT features on longitudinal follow-up of a patient who started with unilateral asymptomatic CNV and eventually developed symptomatic exudative AMD.

    3. Visualization of changes in the foveal avascular zone in both observed and treated diabetic macular edema using optical coherence tomography angiography

      Visualization of changes in the foveal avascular zone in both observed and treated diabetic macular edema using optical coherence tomography angiography
      Background Central vision loss in diabetic retinopathy is commonly related to diabetic macular edema (DME). The objective of this study was to describe changes between consecutive visits on optical coherence tomography angiography (OCTA) of the foveal avascular zone (FAZ) in eyes with DME. Methods 20 eyes from 14 patients with DME were imaged on 2 successive clinic visits separated by at least 1 month. The mean interval between visits was ...

      Purpose: To study the changes in the choroidal layers thickness with age in a healthy population using swept-source optical coherence tomography. Methods: Retrospective data analysis of a subgroup of eyes from a previous single-center, prospective, cross-sectional, noninterventional study. One hundred and sixty-nine healthy eyes were evaluated using swept-source optical coherence tomography. Inclusion criteria were best-corrected visual acuity between 20/20 and 20/25, spherical equivalent between 3 diopters, and no ...

      OCT Technology: Will We Be “Swept” Away?
      A look at the differences between spectral-domain and swept-source OCT, and the potential clinical benefits of swept-source. As is sometimes the case with technology, just when we get comfortable using a device and begin to understand its secrets, limitations and how to best put it to use in our practices, a shiny new instrument arrives and demands our attention. Though this imaging modality has been around for some time, swept-source ...

    6. Optical coherence tomography angiography artifacts in retinal pigment epithelial detachment

      Optical coherence tomography angiography artifacts in retinal pigment epithelial detachment
      Objective To describe optical coherence tomography angiography (OCTA) reflectance artifacts secondary to retinal pigment epithelial detachment (RPED). Design Retrospective review. Methods Four eyes from 4 subjects were included. Three presented with RPED and 1 eye was a normal control. Two eyes diagnosed with RPED and the normal eye were evaluated using en face OCTA centred at the fovea acquired using the RTVue XR Avanti (Optovue Inc). In the third eye ...

    7. Optical Coherence Tomography Angiography in Nonarteritic Anterior Ischemic Optic Neuropathy

      Optical Coherence Tomography Angiography in Nonarteritic Anterior Ischemic Optic Neuropathy
      Background: Optical coherence tomography angiography (OCTA) has demonstrated good utility in qualitative analysis of retinal and choroidal vasculature and therefore may be relevant in the diagnostic and treatment efforts surrounding nonarteritic anterior ischemic optic neuropathy (NAION). Methods: Retrospective, cross-sectional study of 10 eyes of 9 patients with a previous or new diagnosis of NAION that received imaging with OCTA between November 2015 and February 2016. Two independent readers qualitatively analyzed ...

    8. Choroidal Vessel Diameters in Pseudoexfoliation and Pseudoexfoliation Glaucoma Analyzed Using Spectral-Domain Optical Coherence Tomography

      Choroidal Vessel Diameters in Pseudoexfoliation and Pseudoexfoliation Glaucoma Analyzed Using Spectral-Domain Optical Coherence Tomography
      Abstract Purpose of the Study: The purpose of the study was to analyze choroidal vessel diameters in pseudoexfoliation (PXF) and pseudoexfoliation glaucoma (PXFG) using spectral-domain optical coherence tomography (SD-OCT). Materials and Methods: Fifty patients (100 eyes) with PXF and PXFG who underwent high-definition 1-line raster SD-OCT imaging at New England Eye Center, Boston, were retrospectively identified and divided into unilateral PXFG (26 patients, 52 eyes), unilateral PXF (4 patients, 8 ...

    9. OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY AFTER PHOTOCOAGULATION OF TYPE 2 NEOVASCULARIZATION

      OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY AFTER PHOTOCOAGULATION OF TYPE 2 NEOVASCULARIZATION
      Purpose: To illustrate errors in the automated segmentation image analysis of optical coherence tomography angiography after laser photocoagulation therapy for Type 2 neovascularization. Methods: This case report describes a patient with extrafoveal Type 2 neovascularization treated with argon laser photocoagulation evaluated before and after treatment by optical coherence tomography angiography. Results: Disrupted retinal layers after laser photocoagulation therapy lead to segmentation errors. Conclusion: Images of optical coherence tomography angiography are ...

    10. Comparison of Optical Coherence Tomography Angiography and Fluorescein Angiography for the Identification of Retinal Vascular Changes in Eyes With Diabetic Macular Edema

      Comparison of Optical Coherence Tomography Angiography and Fluorescein Angiography for the Identification of Retinal Vascular Changes in Eyes With Diabetic Macular Edema
      BACKGROUND AND OBJECTIVE: To compare the visualization of microaneurysms (MA) and the foveal avascular zone (FAZ) area using optical coherence tomography angiography (OCTA) versus fluorescein angiography (FA) in patients with diabetic macular edema (DME). PATIENTS AND METHODS: Patients were prospectively recruited for same-day imaging on spectral-domain OCTA and FA. OCTA images were automatically segmented into superficial (sOCTA) and deep (dOCTA) capillary plexuses. The number of visible MAs and the FAZ ...

    11. OCT - catching macular degeneration before vision loss

      OCT - catching macular degeneration before vision loss
      Growing old leads to a growing number of health problems, including those that challenge our ability to see. Age-related macular degeneration (AMD) is a disease that -- until recently -- robbed the elderly of the ability to read, drive and see the faces of their loved ones. Thanks to the invention of OCT, doctors can catch the disease before vision is lost. And with the aid of new drugs, AMD can be ...

    12. Analysis of Scleral Feeder Vessel in Myopic Choroidal Neovascularization Using Optical Coherence Tomography Angiography

      Analysis of Scleral Feeder Vessel in Myopic Choroidal Neovascularization Using Optical Coherence Tomography Angiography
      To describe the appearance of a scleral-derived feeder vessel in a highly myopic eye with secondary choroidal neovascularization (CNV) as visualized on both en face high-speed swept-source (SS) optical coherence tomography angiography (OCTA) prototype, and a commercially available spectral-domain (SD) OCTA, with the corresponding en face and cross-sectional structural OCT images. In this case report, a 60-year-old white male presented with high myopia and secondary CNV in the right eye ...
