    2. Three-Dimensional Morphometric Analysis of the Iris by Swept-Source Anterior Segment Optical Coherence Tomography in a Caucasian Population

      Three-Dimensional Morphometric Analysis of the Iris by Swept-Source Anterior Segment Optical Coherence Tomography in a Caucasian Population
      Purpose : We analyzed by swept-source anterior segment optical coherence tomography (SS-ASOCT) the three-dimensional iris morphology in a Caucasian population, and correlated the findings with iris color, iris sectors, subject age, and sex. Methods : One eye each from consecutive healthy emmetropic (refractive spherical equivalent 3 diopters) volunteers were selected for the study. The enrolled eye underwent standardized anterior segment photography to assess iris color. Iris images were assessed by SS-ASOCT for ...

    3. CHOROIDAL GRANULOMAS VISUALIZED BY ENHANCED DEPTH IMAGING OPTICAL COHERENCE TOMOGRAPHY

      CHOROIDAL GRANULOMAS VISUALIZED BY ENHANCED DEPTH IMAGING OPTICAL COHERENCE TOMOGRAPHY
      Purpose: To assess the visualization of choroidal granulomas (CG) by enhanced depth imaging optical coherence tomography (EDI-OCT) and to describe their EDI-OCT characteristics. Methods: Combined indocyanine green (ICG) angiography and EDI-OCT images of 44 CG (sarcoid, tubercular, or Vogt-Koyanagi-Harada related) were reviewed. By ICG angiography, CG were classified as full thickness or partial thickness and as small or large. Two independent operators evaluated EDI-OCT scans over granulomas to record their ...

    4. In vivo analysis of the iris thickness by spectral domain optical coherence tomography

      In vivo analysis of the iris thickness by spectral domain optical coherence tomography
      Purpose To assess the effectiveness of spectral domain optical coherence tomography (SD-OCT) in providing in vivo measurements of iris thickness in healthy and pathological subjects. Methods 14 healthy volunteers and 14 patients with unilateral Fuchs uveitis were enrolled in the study. The two groups were comparable for age, gender and race. Each subject underwent complete clinical examination and anterior segment SD-OCT imaging in both eyes. SD-OCT scans of the iris ...

    5. Evaluation of retinal nerve fiber layer and ganglion cell layer thickness in Alzheimer's disease using spectral-domain optical coherence tomography

      Evaluation of retinal nerve fiber layer and ganglion cell layer thickness in Alzheimer's disease using spectral-domain optical coherence tomography
      Purpose: To evaluate differences between the retinal nerve fiber layer (RNFL) thickness and RNFL + ganglion cell layer (GCL) thickness in patients affected by Alzheimer's disease (AD) and healthy patients using spectral-domain optical coherence tomography (SD-OCT). Methods: This was a case-control prospective study. Twenty-one AD patients and 21 healthy subjects underwent neurological examination, clock drawing test (CDT), mini mental state examination (MMSE) and comprehensive ophthalmic evaluation with visual acuity. SD-OCT ...

    6. Retrobulbar Structure Visualization with Enhanced Depth Imaging Optical Coherence Tomography

      Retrobulbar Structure Visualization with Enhanced Depth Imaging Optical Coherence Tomography
      Purpose: To assess enhanced depth imaging optical coherence tomography (EDI-OCT) visualization of deep posterior pole structures and retrobulbar tissues in myopic eyes and evaluate ocular structural elements that influenced this capability. Methods: Thirty consecutive myopic eyes (-6 diopters) from 21 patients were enrolled. Exclusion criteria included any pathological condition affecting the posterior pole. Patients underwent biometry to assess axial length, and irises were classified as darkly or lightly pigmented. EDI-OCT ...

    7. Aligning scan locations from consecutive spectral-domain optical coherence tomography examinations: a comparison among different strategies

      Aligning scan locations from consecutive spectral-domain optical coherence tomography examinations: a comparison among different strategies
      Purpose: To compare intrasession repeatability values produced by different spectral-domain optical coherence tomography (SD-OCT) instruments when measuring macular retinal thickness from consecutive examinations. Methods: A total of 40 eyes from 23 healthy subjects and 47 eyes from 42 patients with macular edema were enrolled in the study. Subjects underwent two consecutive SD-OCT examinations using three instruments: Spectralis HRA+OCT (Heidelberg Engineering, Heidelberg, Germany), Cirrus (Carl Zeiss Meditec Inc., Dublin, CA ...

    8. Displayed Reflectivity Of Choroidal Neovascular Membranes By Optical Coherence Tomography Correlates With Presence of Leakage By Fluorescein Angiography

      Displayed Reflectivity Of Choroidal Neovascular Membranes By Optical Coherence Tomography Correlates With Presence of Leakage By Fluorescein Angiography
      Purpose: To evaluate and correlate the displayed optical reflectivity of choroidal neovascularization (CNV) subretinal material on spectral-domain optical coherence tomography with the presence of dye leakage on fluorescein angiography (FA).Methods: Thirty-nine eyes of 39 patients with a diagnosis of predominantly classic CNV from age-related macular degeneration underwent simultaneous spectral-domain optical coherence tomography and FA imaging. Eight patients had a newly diagnosed untreated CNV. Thirty-one patients had already been treated ...

    9. Reproducibility of Retinal Thickness Measurements on Normal and Pathologic Eyes by Different Optical Coherence Tomography Instruments

      Reproducibility of Retinal Thickness Measurements on Normal and Pathologic Eyes by Different Optical Coherence Tomography Instruments
      Purpose:To compare retinal thickness measurements produced by different time-domain and spectral-domain optical coherence tomography (TD-OCT and SD-OCT) devices when imaging normal and pathologic eyes.Design:Prospective, observational study in an academic institutional setting.Methods:A total of 110 eyes were imaged by 6 different OCT devices: Stratus and Cirrus (Carl Zeiss Meditec Inc), Spectralis HRA+OCT (Heidelberg Engineering), RTVue-100 (Optovue Inc), SDOCT Copernicus HR (Optopol Technology S.A.), and ...

    10. Artifacts In Automatic Retinal Segmentation Using Different Optical Coherence Tomography Instruments

      Purpose: The purpose of this study was to compare and evaluate artifact errors in automatic inner and outer retinal boundary detection produced by different time-domain and spectral-domain optical coherence tomography (OCT) instruments.Methods: Normal and pathologic eyes were imaged by six different OCT devices. For each instrument, standard analysis protocols were used for macular thickness evaluation. Error frequencies, defined as the percentage of examinations affected by at least one error ...

    11. Diagnosis of macular pseudoholes and lamellar macular holes: is optical coherence tomography the "gold standard"?

      Aim: To assess fundus autofluorescence (AF) for differential diagnosis of macular pseudoholes (MPH) and lamellar macular holes (LMH) evaluated by optical coherence tomography (OCT) as the "gold standard".Methods: The files on 50 eyes of 46 consecutive patients diagnosed by OCT as having a foveal defect with residual retinal tissue at the bottom were reviewed. Retinal thickness was measured at the foveal centre and 750 µm temporally and nasally to ...
