    1. Influence of Blue Light-filtering Intraocular Lenses on Retinal Nerve Fiber Layer Measurements by Spectral-domain Optical Coherence Tomography

      Influence of Blue Light-filtering Intraocular Lenses on Retinal Nerve Fiber Layer Measurements by Spectral-domain Optical Coherence Tomography
      Purpose: The purpose of this study was to assess the influence of blue light-filtering intraocular lenses (IOL) on peripapillary retinal nerve fiber layer (RNFL) thickness measurements by spectral-domain (SD) optical coherence tomography (OCT). Methods: This prospective study included 50 eyes of 50 patients. Patients were randomly assigned to receive either a blue light-filtering IOL (acrysof IQ (SN60WF) [Alcon]) or a clear IOL (Tecnis (Z9003) [AMO]). The peripapillary RNFL thickness was measured using a Cirrus SD OCT before and 8 weeks after cataract surgery. Perioperative differences in RNFL thickness measurements and signal strengths (SS) were evaluated and compared in both IOL ...

    2. Comparison of the Optic Nerve Imaging by Time-Domain Optical Coherence Tomography and Fourier-Domain Optical Coherence Tomography in Distinguishing Normal Eyes From Those With Glaucoma

      Comparison of the Optic Nerve Imaging by Time-Domain Optical Coherence Tomography and Fourier-Domain Optical Coherence Tomography in Distinguishing Normal Eyes From Those With Glaucoma
      Purpose: To assess agreement in cup-to-disc ratio (CDR) estimation between stereoscopic optic disc photography, time-domain optical coherence tomography (OCT), and Fourier-domain OCT, and to compare the discriminating ability of optic nerve head (ONH) parameters by time-domain OCT and Fourier-domain OCT for glaucoma detection. Methods: Participants underwent stereoscopic photography, Stratus OCT (fast optic disc scan), and RTVue-100 (nerve head mapping), at the same visit. Vertical and horizontal CDRs (VCDR and HCDR) from stereoscopic photography were determined by averaging the results from 2 independent glaucoma specialists. VCDR, HCDR, disc area, cup area, rim area, and cup-to-disc area ratio were acquired from the ...

    3. Effect of signal strength on reproducibility of circumpapillary retinal nerve fiber layer thickness measurement and its classification by spectral-domain optical coherence tomography

      Effect of signal strength on reproducibility of circumpapillary retinal nerve fiber layer thickness measurement and its classification by spectral-domain optical coherence tomography

      Abstract Purpose  To assess the effect of signal strength (SS) on the reproducibility of circumpapillary retinal nerve fiber layer (cpRNFL) thickness measurement (measurement agreement) and its color-coded classification (classification agreement) by Cirrus spectral-domain optical coherence tomography (OCT). Methods  Seven hundred and eighty-nine participants, consecutively enrolled from December 2009 to August 2010, underwent two repeated Cirrus OCT scans to measure cpRNFL thickness (optic disc cube 200 × 200). Intraclass correlation (ICC) and linear-weighted kappa coefficient (κ) were calculated as indicators for cpRNFL measurement and classification agreement. The difference in cpRNFL thickness measurements between repeated OCT scans (inter-scan measurement difference) was correlated with mean ...

    4. Determinants of perimacular inner retinal layer thickness in normal eyes measured by Fourier-domain optical coherence tomography

      Determinants of perimacular inner retinal layer thickness in normal eyes measured by Fourier-domain optical coherence tomography

      Purpose: To determine the effects of age, gender, spherical equivalent, axial length, anterior chamber depth, optic disc area, and central corneal thickness on perimacular inner retinal layer thickness in the normal human eye as measured by Fourier-domain optical coherence tomography (FD-OCT). Methods: In this cross-sectional observational study, 182 Korean normal subjects aged from 22 to 84 years were included. To obtain the inner retinal layer thickness, perimacular ganglion cell complex (GCC) thickness, which extends from the internal limiting membrane to the inner nuclear layer, was measured by FD-OCT (RTVue-100; Optovue Inc, Fremont, CA) on one randomly selected eye of each ...

    5. Effect of signal strength on reproducibility of peripapillary retinal nerve fiber layer thickness measurement and its classification by time-domain optical coherence tomography

      Effect of signal strength on reproducibility of peripapillary retinal nerve fiber layer thickness measurement and its classification by time-domain optical coherence tomography
      PURPOSE: To assess the effect of signal strength (SS) on reproducibility of peripapillary retinal nerve fiber layer (RNFL) thickness measurement (measurement agreement) and its color-coded classification (classification agreement) by time-domain optical coherence tomography (OCT). METHODS: Two consecutive Stratus OCT scans with the Fast RNFL protocol were performed in 658 participants. Intraclass correlations and the linear-weighted kappa coefficient were calculated as indicators of RNFL measurement and classification agreement in participants grouped according to the difference in SS between consecutive OCT scans (interscan SS difference). RESULTS: Groups with a larger interscan SS difference (= 2) had lower measurement agreement than those with a ...

    6. Effect of Signal Strength on Agreements for Retinal Nerve Fiber Layer Thickness Measurement and Its Color Code Classification Between Stratus and Cirrus Optical Coherence Tomography

      Effect of Signal Strength on Agreements for Retinal Nerve Fiber Layer Thickness Measurement and Its Color Code Classification Between Stratus and Cirrus Optical Coherence Tomography
      Purpose: To assess the effect of signal strength (SS) on concordance rate or agreement on retinal nerve fiber layer (RNFL) thickness measurement (measurement agreement) and its color code classification (classification agreement) between Stratus optical coherence tomography (OCT) and Cirrus OCT. Patients and Methods: From 300 participants who underwent both Stratus and Cirrus OCT scans at the same visit (SS >=6), intraclass correlation and weighted [kappa] coefficients were calculated as indicators for RNFL measurement agreement and classification agreement between 2 OCTs. Results: In inferior and superior quadrants, agreements were excellent (intraclass correlation) or good ([kappa]) and neither the measurement nor the ...

    7. Spectral-Domain Optical Coherence Tomography for Detection of Localized Retinal Nerve Fiber Layer Defects in Patients With Open-Angle Glaucoma

      Spectral-Domain Optical Coherence Tomography for Detection of Localized Retinal Nerve Fiber Layer Defects in Patients With Open-Angle Glaucoma
      Objective  To evaluate and compare time-domain (Stratus) and spectral-domain (Cirrus; both Carl Zeiss Meditec, Dublin, California) optical coherence tomography (OCT) for the detection of localized retinal nerve fiber layer (RNFL) defects in patients with open-angle glaucoma. Methods  Patients with localized RNFL defects and age-matched normal control participants were consecutively enrolled from July 1 to December 31, 2008. Sixty-six eyes from 66 patients and 66 eyes from 66 normal controls were imaged with Stratus OCT (fast RNFL scan mode) and Cirrus OCT (optic disc cube mode). The ability to detect the RNFL defect by using quadrant clock-hour maps from both OCTs ...

    8. Comparing the ganglion cell complex and retinal nerve fibre layer measurements by Fourier domain OCT to detect glaucoma in high myopia

      Comparing the ganglion cell complex and retinal nerve fibre layer measurements by Fourier domain OCT to detect glaucoma in high myopia
      Aim To compare the diagnostic ability to detect glaucomatous changes between peripapillary retinal nerve fibre layer (RNFL) thickness and the macular ganglion cell complex (GCC) in highly myopic patients using Fourier domain optical coherence tomography. Methods Participants, consecutively enrolled from January 2009 to June 2009, were imaged with RTVue-100 (NHM4 and MM7 scan). The sensitivity and specificity of a colour code less than 5% (red or yellow) for glaucoma diagnosis were calculated. Area under the receiver operator characteristic (AUROC) curves were generated to assess the ability of each parameter to detect glaucomatous changes. Results 73 normal controls and 77 glaucoma ...
