    2. Discordance of Disc-Fovea Raphe Angles Determined by Optical Coherence Tomography and MP-3 Microperimetry in Eyes With a Glaucomatous Hemifield Defect

      Discordance of Disc-Fovea Raphe Angles Determined by Optical Coherence Tomography and MP-3 Microperimetry in Eyes With a Glaucomatous Hemifield Defect
      Purpose : The purpose of this study was to evaluate the concordance of a temporal raphe architecture estimated using optical coherence tomography (OCT) and MP-3 microperimetry. Methods : We enrolled 25 eyes with either an upper or lower glaucomatous hemifield defect, as detected on the Humphrey visual field 30-2 test. A structural temporal raphe was extrapolated from visible end points of retinal nerve fiber bundles present in a perimetrically normal hemiretina on ...

    3. The Ability of SD-OCT to Differentiate Early Glaucoma With High Myopia From Highly Myopic Controls and Nonhighly Myopic Controls

      The Ability of SD-OCT to Differentiate Early Glaucoma With High Myopia From Highly Myopic Controls and Nonhighly Myopic Controls
      Purpose : Optical coherence tomography (OCT) instruments do not embed a normative database from highly myopic normal (HMN) eyes. The abilities of three OCT instruments to detect early glaucoma with high myopia were compared using the two controls with or without high myopia. Methods : A total of 52 early glaucomatous eyes (mean deviation 6.0 dB) with high myopia (spherical equivalent 6.0 diopters [HMG]), 54 HMN eyes, and 90 nonhighly ...

    4. Effects of Axial Length and Age on Circumpapillary Retinal Nerve Fiber Layer and Inner Macular Parameters Measured by 3 Types of SD-OCT Instruments

      Effects of Axial Length and Age on Circumpapillary Retinal Nerve Fiber Layer and Inner Macular Parameters Measured by 3 Types of SD-OCT Instruments
      Purposes: To evaluate the effects of axial length and age on the circumpapillary retinal nerve fiber layer (cpRNFL) and the inner macular parameters measured using 3 spectral-domain optical coherence tomography (OCT) instruments. Methods: A total of 102 normal eyes (1 eye per subject) were imaged using Cirrus, RTVue, and 3D-OCT. The cpRNFL and the macular retinal nerve fiber layer (mRNFL), the ganglion cell layer+inner plexiform layer (GCLIPL), and the ...

    5. Difference in correspondence between visual field defect and inner macular layer thickness measured using three types of spectral-domain OCT instruments

      Difference in correspondence between visual field defect and inner macular layer thickness measured using three types of spectral-domain OCT instruments
      Purpose To compare the relationship between visual field sensitivity (VFS) and macular parameters measured using three spectral-domain optical coherence tomography (SD-OCT) instruments and to determine a base level (=floor effect) for macular parameters. Methods We imaged 127 glaucomatous eyes (1 eye per subject) using three different OCT instruments, i.e., the Cirrus , RTVue and 3D OCT devices; 76 normal eyes were evaluated as controls using the same instruments. The thicknesses ...

    6. The detection of macular analysis by SD-OCT for optic chiasmal compression neuropathy and nasotemporal overlap

      The detection of macular analysis by SD-OCT for optic chiasmal compression neuropathy and nasotemporal overlap
      Purposes: To assess the diagnostic performance of the macular parameters detected by spectral domain-optical coherence tomography (SD-OCT) in band atrophy (BA) eyes. Methods: Forty-nine BA eyes with permanent temporal hemianopia and 89 normal eyes were enrolled. Any patients who had nasal visual field loss were excluded. Each participant was imaged by 3D OCT-2000, and 1010 grids in the macula were automatically allocated. The thickness of the macular retinal nerve fiber ...

    7. Cluster analyses of grid-pattern display in macular parameters using optical coherence tomography for glaucoma diagnosis

      Cluster analyses of grid-pattern display in macular parameters using optical coherence tomography for glaucoma diagnosis
      Purpose: Using spectral-domain optical coherence tomography (SD-OCT), we assessed the ability of cluster analyses based on the grid-pattern of macular parameters to detect glaucoma. Methods: Seventy-five normal eyes, 64 early glaucomatous eyes (EG) and 40 preperimetric glaucomatous eyes (PPG) were enrolled. Each participant was imaged using 3D OCT to examine the macular retinal nerve fiber layer (mRNFL) and the thickness of the ganglion cell layer together with the inner plexiform ...

    8. The ability of macular parameters and circumpapillary retinal nerve fiber layer by three SD-OCT instruments to diagnose highly myopic glaucoma

      The ability of macular parameters and circumpapillary retinal nerve fiber layer by three SD-OCT instruments to diagnose highly myopic glaucoma
      Purpose: To compare the ability of circumpapillary retinal nerve fiber layer (cpRNFL) thickness and macular parameters obtained by three spectral-domain optical coherence tomography (SD-OCT) instruments to detect highly myopic glaucoma. Methods: In this study, 84 glaucomatous eyes, 53 normal eyes with high myopia and 86 normal eyes (not highly myopic) were enrolled. Each participant was imaged using Cirrus, RTVue and 3D OCT to evaluate the average and quadrant cpRNFL thicknesses ...

    9. Structure–function relationship among three types of spectral-domain optical coherent tomography instruments in measuring parapapillary retinal nerve fibre layer thickness

      Structure–function relationship among three types of spectral-domain optical coherent tomography instruments in measuring parapapillary retinal nerve fibre layer thickness
      Purpose: To compare the relationships of parapapillary retinal nerve fibre layer (RNFL) thickness among three spectral-domain optical coherence tomography (SD-OCT) instruments with visual field sensitivity (VFS). Methods: One hundred and thirteen eyes of 113 Japanese subjects with glaucoma (mean deviation in standard automated perimetry = 8.9 6.7 dB) were imaged by Cirrus, RTVue and 3D OCT. The average hemi-superior and hemi-inferior RNFL thicknesses were obtained. In addition, the structurefunction ...

    10. Effects of ocular rotation on parapapillary retinal nerve fiber layer thickness analysis measured with spectral-domain optical coherence tomography

      Effects of ocular rotation on parapapillary retinal nerve fiber layer thickness analysis measured with spectral-domain optical coherence tomography
      Purpose To evaluate the effects of ocular rotation on parapapillary retinal nerve fiber layer (RNFL) thickness measured by spectral-domain optical coherence tomography (SD-OCT). Patients and methods Eighty-eight normal and 205 glaucomatous eyes were studied. RNFL thickness was measured by 3D OCT. Ocular rotation angle was measured from a fundus image obtained by a non-mydriatic fundus camera equipped with 3D OCT. The average, hemi-superior, and hemi-inferior RNFL thicknesses as well as ...

    12. Comparison of Mean Deviation With AGIS and Cigts Scores in Association With Structural Parameters in Glaucomatous Eyes

      Objective: To evaluate which of the 3 clinically used visual field indices including mean deviation (MD), Advanced Glaucoma Intervention Study (AGIS) score, and Collaborative Initial Glaucoma Treatment Study (CIGTS) score are best in evaluating functional damage of glaucomatous optic neuropathy. Methods: In 213 glaucomatous eyes, peripapillary retinal nerve fiber layer thickness (RNFLT) and optic disc configuration were measured with Stratus optical coherence tomography and Heidelberg Retina Tomograph-2, respectively. Visual field ...
