    2. Iridotrabecular contact observed using anterior segment three-dimensional OCT in eyes with a shallow peripheral anterior chamber

      Iridotrabecular contact observed using anterior segment three-dimensional OCT in eyes with a shallow peripheral anterior chamber
      Purpose: To evaluate the prevalence and range of iridotrabecular contact (ITC) in eyes with a shallow peripheral anterior chamber (AC) by using anterior segment swept-source optical coherence tomography (AS-SS-OCT) and to compare the results with those obtained with ultrasound biomicroscopy (UBM) and gonioscopy. Methods: Forty-three shallow peripheral AC eyes in 43 consecutive patients underwent gonioscopy. Cross-sectional images throughout the angle circumference (i.e., 360 degrees) were obtained with AS-SS-OCT (SS-1000 ...

    3. Circle and Grid-wise Analyses of Peripapillary Nerve Fiber Layers by Spectral Domain Optical Coherence Tomography in Early Stage Glaucoma

      Circle and Grid-wise Analyses of Peripapillary Nerve Fiber Layers by Spectral Domain Optical Coherence Tomography in Early Stage Glaucoma
      PURPOSE. To study diagnostic performances of circle and grid-wise analyses of peripapillary retinal nerve fiber layer thickness (RNFLT) using spectral domain optical coherence tomography (SD-OCT) in early stage glaucoma. METHODS. Eighty-nine open-angle glaucoma (OAG) eyes (mean deviation, -2.5 1.8 dB) and 89 age-matched normal eyes were studied. Peripapillary RNFLT was analyzed using SD-OCT raster scan in a 6.0 6.0 mm area. Averaged RNFLT was calculated over ...

    5. Reproducibility of Thickness Measurements of Macular Inner Retinal Layers Using SD-OCT with or without Correction of Ocular Rotation

      Reproducibility of Thickness Measurements of Macular Inner Retinal Layers Using SD-OCT with or without Correction of Ocular Rotation
      Purpose. To evaluate the inter-visit reproducibility of spectral-domain optical coherence tomography (SD-OCT) measurement of the macular retinal nerve fiber layer thickness (mRNFLT), combined ganglion cell layer and inner plexiform layer (GCL+IPL) thickness, and ganglion cell complex (GCC) thicknesses (sum of mRNFLT and GCL+IPL thicknesses) compared with that of circumpapillary RNFLT (cpRNFLT) and the effect of ocular rotation on reproducibility. Methods. SD-OCT imaging was performed twice on different days ...

    6. Spectral-Domain Optical Coherence Tomography of β-zone Peripapillary Atrophy: Influence of Myopia and Glaucoma

      Spectral-Domain Optical Coherence Tomography of β-zone Peripapillary Atrophy: Influence of Myopia and Glaucoma
      Purpose: To investigate the influence of glaucoma and myopia on the cross-sectional configuration of β-zone peripapillary atrophy (PPA-β) using spectral-domain optical coherence tomography (SD-OCT). Methods: Among 100 eyes of 100 consecutive patients with POAG regardless of intraocular pressure level and 100 eyes of 100 normal subjects, cross-sectional B-scan images of PPA-β obtained with SD-OCT were evaluated. PPA bed configurations were classified and associated factors were studied with multivariate analysis. Results ...

    7. Noninvasive Observations of Peripheral Angle in Eyes After Penetrating Keratoplasty Using Anterior Segment Fourier-Domain Optical Coherence Tomography

      Noninvasive Observations of Peripheral Angle in Eyes After Penetrating Keratoplasty Using Anterior Segment Fourier-Domain Optical Coherence Tomography
      Purpose: To examine iridotrabecular contact (ITC) as a peripheral anterior synechia (PAS) of patients who underwent penetrating keratoplasty (PKP) using anterior segment Fourier-domain optical coherence tomography (OCT). Methods: Retrospective, observational case series. ITC, ITC index, and ITC area of 60 eyes of 52 patients who underwent PKP at the Department of Ophthalmology in the University of Tokyo Hospital (mean follow-up time 102.8 +/- 116.1 months postoperation) were calculated using ...

    8. Effects of Age, Sex, and Axial Length on the Three-Dimensional Profile of Normal Macular Layer Structures

      Effects of Age, Sex, and Axial Length on the Three-Dimensional Profile of Normal Macular Layer Structures
      Purpose. To identify sex-related differences and age-related changes in individual retinal layer thicknesses in a population of healthy eyes across the lifespan, using spectral domain optical coherence tomography (SD-OCT). Methods. In seven institutes in Japan, mean thicknesses of the retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer (INL), outer plexiform layer (OPL), outer nuclear layer (ONL), photoreceptor inner segment (IS), and photoreceptor ...
