    2. Long-term reproducibility of GC-IPL thickness measurements using spectral domain optical coherence tomography in eyes with high myopia

      Long-term reproducibility of GC-IPL thickness measurements using spectral domain optical coherence tomography in eyes with high myopia
      Although ganglion cell inner plexiform layer (GC-IPL) analysis in the patients with high myopia is useful, there have been few reports to analyze of the reliability for long-term measured GC-IPL thickness. We aimed to analyze the long-term reproducibility of thickness measurements of the GC-IPL using spectral-domain optical coherence tomography (SD-OCT) in patients with high myopia and identify factors that affect such reproducibility. 99 eyes from 99 patients with high myopia ...

    3. Repeatability of vessel density measurements using optical coherence tomography angiography in retinal diseases

      Repeatability of vessel density measurements using optical coherence tomography angiography in retinal diseases
      Aim To analyse the repeatability of vessel density (VD) measurements using optical coherence tomography angiography (OCTA) in patients with retinal diseases. Methods Two consecutive VD measurements using OCTA were analysed prospectively in patients with retinal diseases (diabetic macular oedema (DME), retinal vein occlusion (RVO) with macular oedema, epiretinal membrane (ERM), wet age-related macular degeneration (AMD)). The intraclass correlation coefficient (ICC), coefficient of variation (CV) and test-retest SD of VD measurements ...

    4. THICKNESS OF THE MACULA, RETINAL NERVE FIBER LAYER, AND GANGLION CELL–INNER PLEXIFORM LAYER IN THE AGE-RELATED MACULAR DEGENERATION: The Repeatability Study of Spectral Domain Optical Coherence Tomography

      THICKNESS OF THE MACULA, RETINAL NERVE FIBER LAYER, AND GANGLION CELL–INNER PLEXIFORM LAYER IN THE AGE-RELATED MACULAR DEGENERATION: The Repeatability Study of Spectral Domain Optical Coherence Tomography
      Purpose: To determine the repeatability of measuring the thickness of the central macula, retinal nerve fiber layer, and ganglion cellinner plexiform layer (GC-IPL) using spectral domain optical coherence tomography (Cirrus HD-OCT) in eyes with age-related macular degeneration. Methods: One hundred and thirty-four eyes were included. The measurement repeatability was assessed by an experienced examiner who performed two consecutive measurements using a 512 128 macular cube scan and a 200 200 ...

    5. Plasma treatment effect on angiogenesis in wound healing process evaluated in vivo using angiographic optical coherence tomography

      Plasma treatment effect on angiogenesis in wound healing process evaluated in vivo using angiographic optical coherence tomography
      Non-thermal atmospheric pressure plasma holds promise for promoting wound healing. However, plasma-induced angiogenesis, which is important to better understand the underlying physics of plasma treatment effect on wound healing, remains largely unknown. We therefore evaluated the effect of non-thermal plasma on angiogenesis during wound healing through longitudinal monitoring over 30 days using non-invasive angiographic optical coherence tomography imaging in vivo . We demonstrate that the plasma-treated vascular wound area of mouse ...

    6. Prediction of Retinal Ischemia in Branch Retinal Vein Occlusion: Spectral-Domain Optical Coherence Tomography Study

      Prediction of Retinal Ischemia in Branch Retinal Vein Occlusion: Spectral-Domain Optical Coherence Tomography Study
      Purpose : To investigate the relationship between spectral-domain optical coherence tomography (SD-OCT) measurements and retinal nonperfusion in patients with branch retinal vein occlusion (BRVO). Methods : Forty-one patients with BRVO who had recovered from macular edema and had been followed for 2 years were included via retrospective, medical record review. Patients were divided into two groups that included 20 nonischemic eyes and 21 ischemic eyes, and 41 fellow control eyes were also ...

    7. Effects of Refractive Power on Macular Thickness Measurement Using Spectral-Domain Optical Coherence Tomography

      Effects of Refractive Power on Macular Thickness Measurement Using Spectral-Domain Optical Coherence Tomography
      Purpose: To investigate the effects of refractive power on macular thickness measurements by spectral-domain optical coherence tomography (SD-OCT). Subjects and Methods: For this prospective cohort study, a total of 50 eyes from 50 normal subjects with no systemic or ocular disease and no history of ocular surgery were studied from February 2014 to May 2014. We used soft contact lenses with a wide range of diopters to change the refractive ...

    8. Thickness of the Macula, Retinal Nerve Fiber Layer, and Ganglion Cell Layer in the Epiretinal Membrane: The Repeatability Study of Optical Coherence Tomography

      Thickness of the Macula, Retinal Nerve Fiber Layer, and Ganglion Cell Layer in the Epiretinal Membrane: The Repeatability Study of Optical Coherence Tomography
      Purpose : To analyze the repeatability of measurements of the thicknesses of the macula, retinal nerve fiber layer (RNFL), and ganglion cell inner plexiform layer (GCIPL) using spectral-domain optical coherence tomography (SD-OCT) in the epiretinal membrane (ERM). Methods : The prospective study analyzed patients who visited our retinal clinic from June 2013 to January 2014. An experienced examiner measured the thicknesses twice using macular cube 512 128 and optic disc cube 200 ...

    9. Ganglion Cell-Inner Plexiform Layer Thickness in Retinal Diseases: Repeatability Study of Spectral Domain Optical Coherence Tomography

      Ganglion Cell-Inner Plexiform Layer Thickness in Retinal Diseases: Repeatability Study of Spectral Domain Optical Coherence Tomography
      Purpose To analyze the repeatability of measuring the thickness of the ganglion cell inner-plexiform layer using spectral domain optical coherence tomography by auto-segmentation in various retinal diseases. Design Test-retest reliability analysis Methods 180 patients who visited our clinic between April and December 2013 were included. An experienced examiner obtained two consecutive measurements from a macular cube 512 128 scan. The patients were divided into three groups according to central macular ...

    10. Diurnal Variation of Retina Thickness Measured with Time Domain and Spectral Domain Optical Coherence Tomography in Healthy Subjects

      Diurnal Variation of Retina Thickness Measured with Time Domain and Spectral Domain Optical Coherence Tomography in Healthy Subjects
      Purpose. To investigate diurnal variations in macular thickness and total macular volume using time domain optical coherence tomography (TD-OCT) and spectral domain OCT (SD-OCT) in healthy subjects. Methods. Data were derived from 52 eyes of 52 healthy subjects. Macular thickness, macular volume was measured by using TD-OCT and SD-OCT at 8 AM and 6 PM. Results. Comparing TD-OCT measurements, retinal thickness was significantly greater in the afternoon than in the ...
