    2. Retinal blood flow detection in diabetic patients by Doppler Fourier domain optical coherence tomography

      Retinal blood flow detection in diabetic patients by Doppler Fourier domain optical coherence tomography
      We present human retinal blood flow investigation for diabetic patients using Doppler Fourier domain optical coherence tomography (FDOCT). The scanning pattern consisted of two concentric circles around the optic nerve head. The blood flow in one patient with diabetes and no retinpathy and another ... [Opt. Express 17, 4061-4073 (2009)]

    3. Investigation of retinal blood flow in normal and glaucoma subjects by doppler fourier-domain optical coherence tomography

      We present in vivo human retinal blood flow investigation using Fourier domain optical coherence tomography. A pilot study was performed to evaluate the total retinal blood flow in glaucoma patients and normal subjects. For normal people, the measured total retinal flow was between 40.8 and 52.9 [mu ...

    5. Agreement Between Stratus and Visante Optical Coherence Tomography Systems in Tear Meniscus Measurements.

      Aim: To compare the tear meniscus height (TMH) measurements provided by the Stratus and Visante optical coherence tomography systems. Methods: A cross-section image of the lower tear meniscus was captured with both instruments in 26 volunteers. An external application was used to manually measure the TMH as imaged by the Stratus; measurements by the Visante were analyzed by the internal software. Only 1 eye for each subject was considered for ...

      Purpose: To describe morphologic features of traumatic macular holes on optical coherence tomography and to correlate them with clinical findings. Methods: Seventy-three consecutive patients diagnosed with full-thickness traumatic macular holes involving the fovea underwent complete ophthalmic evaluation followed by horizontal and vertical li...

    7. Spectral Domain Optical Coherence Tomography for Proliferative Diabetic Retinopathy With Subhyaloid Hemorrhage

      A prototype 6-µm axial resolution spectral domain optical coherence tomography (SD-OCT) device was used to image the retina of a patient with uncontrolled diabetes mellitus who had proliferative diabetic retinopathy with subhyaloid hemorrhage. A raster scan pattern with 128 B-scans covering a 6 × 6 × 2-mm volume of the retina was obtained. SD-...

    9. Keratoconus Diagnosis with Optical Coherence Tomography Pachymetry Mapping

      Objective To detect abnormal corneal thinning in keratoconus using pachymetry maps measured by high-speed anterior segment optical coherence tomography (OCT). Design Cross-sectional observational study. Participants Thirty-seven keratoconic eyes from 21 subjects and 36 eyes from 18 normal subjects. Methods The OCT system operated at a 1.3 μm wavelength with a scan rate of 2000 axial scans per second. A pachymetry scan pattern (8 radials, 128 axial scans each; 10 ...

    10. Clinical and research applications of anterior segment optical coherence tomography – a review

      al coherence tomography (OCT) is being employed more and more often to image pathologies and surgical anatomy within the anterior segment, specifically in anterior chamber biometry, corneal pachymetric mapping, angle evaluation and high-resolution cross-sectional imaging. The cross-sectional imaging capability of OCT is similar to ultrasound, but its higher resolution allows OCT to measure and visualize very fine anatomic structures. No contact is required. In this review, we describe the utility ...

    11. Quantitative Optical Coherence Tomography Findings in Various Subtypes of Neovascular Age-Related Macular Degeneration

      PURPOSE. To compare the volume of various spaces visible on optical coherence tomography (OCT) images in different angiographic lesion subtypes of neovascular age-related macular degeneration (AMD). METHODS. Sixty-six cases of previously untreated, active subfoveal choroidal neovascularization (CNV) associated with AMD were retrospectively collected. CNV lesions were classified as occult with no classic CNV, minimally classic CNV, predominantly classic CNV, or CNV lesions with associated retinal angiomatous proliferation (RAP). Corresponding OCT ...

    12. Relationship Between Optical Coherence Tomography Retinal Parameters and Visual Acuity in Neovascular Age-Related Macular Degeneration

      Purpose To investigate the relationship between optical coherence tomography (OCT)-derived measurements of retinal morphology and visual acuity in patients with neovascular age-related macular degeneration (AMD). Design Retrospective cross-sectional study. Participants A total of 216 consecutive patients (216 eyes) newly diagnosed with neovascular AMD who underwent StratusOCT imaging at the time of diagnosis. Methods Best-corrected Snellen visual acuity was recorded for each patient. Raw exported StratusOCT images for each patient ...
