      This Ophthalmic Image shows swept-source optical coherence tomography of glaucoma tube changes after Baerveldt glaucoma implant into the ciliary sulcus. A woman developed Takayasu disease and neovascular glaucoma in her early 20s. She underwent cardiovascular bypass surgery, but lost vision in her left eye. When another cardiovascular bypass was planned in her mid-40s, 95% of her right eye angle was closed, but her intraocular pressure (IOP) did not exceed the ...

      Changes in morphology and visual function over time in mouse models of retinal degeneration: an SD-OCT, histology, and electroretinography study
      Purpose To examine the long-term natural course of retinal degeneration in rd10 and rd12 mice using serial spectral-domain optical coherence tomography (SD-OCT), electroretinography/electroretinograms (ERGs), and histological analysis. Methods Photoreceptor layer thickness and the ability to visualize photoreceptor ellipsoid zones were analyzed using SD-OCT images, and these images were compared with hematoxylin and eosin-stained sections and electron microscopy images. The a- and b-wave amplitudes of the ERGs were analyzed. Results ...

    6. 0.54 μm resolution two-photon interference with dispersion cancellation for quantum optical coherence tomography

      0.54 μm resolution two-photon interference with dispersion cancellation for quantum optical coherence tomography
      Quantum information technologies harness the intrinsic nature of quantum theory to beat the limitations of the classical methods for information processing and communication. Recently, the application of quantum features to metrology has attracted much attention. Quantum optical coherence tomography (QOCT), which utilizes two-photon interference between entangled photon pairs, is a promising approach to overcome the problem with optical coherence tomography (OCT): As the resolution of OCT becomes higher, degradation of ...

      Structural dissociation of optic disc margin components with optic disc tilting: a spectral domain optical coherence tomography study
      Purpose To investigate the dissociation of the Bruchs membrane opening (BMO) from the scleral canal opening (SO) of the optic disc. Methods In this prospective, cross-sectional, observational study, 101 eyes from 101 patients or suspected subjects of primary open angle glaucoma were included. Enhanced depth imaging spectral domain optical coherence tomography images along the long axis of the optic disc were used to visualize better the deep structures around the ...

      Effect of Axial Length on Macular Ganglion Cell Complex Thickness and on Early Glaucoma Diagnosis by Spectral-Domain Optical Coherence Tomography
      Purpose: To investigate the effects of the axial length (AL)-related ocular magnification on the thickness of the macular ganglion cell complex (mGCC), and the diagnostic accuracy of the built-in normative database of the spectral-domain optical coherence tomographic (SD-OCT) instrument for early glaucoma detection. Methods: This retrospective study included 41 eyes with early primary open-angle glaucoma and 36 normal eyes. The mGCC thickness within a 20-degree circle, equivalent to a ...

    9. Comparative analysis method of permanent metallic stents (XIENCE) and bioresorbable poly-L-lactic (PLLA) scaffolds (Absorb) on optical coherence tomography at baseline and follow-up

      Comparative analysis method of permanent metallic stents (XIENCE) and bioresorbable poly-L-lactic (PLLA) scaffolds (Absorb) on optical coherence tomography at baseline and follow-up
      Aims: Fully bioresorbable Absorb poly-L-lactic-acid (PLLA) scaffolds (Abbott Vascular, Santa Clara, CA, USA) are a novel approach for the treatment of coronary narrowing. Due to the translucency of the material (PLLA), the optical coherence tomography (OCT) measurement methods used in the ABSORB trials were unique but not applicable for permanent metallic stents. When the Absorb scaffold and metallic stents are compared in the context of randomised trials, it is challenging ...

      Comparison of neointimal coverage between everolimus-eluting stents and sirolimus-eluting stents: an optical coherence tomography substudy of the RESET (Randomized Evaluation of Sirolimus-eluting versus Everolimus-eluting stent Trial)
      Aims: The aim of the present study was to compare vascular healing response between the first-generation sirolimus-eluting stent (SES) and the second-generation everolimus-eluting stent (EES) by using optical coherence tomography (OCT). Methods and results: The RESET was a prospective, multicentre, randomised, open-label trial comparing EES and SES. Of the 3,197 patients enrolled in the RESET, nine-month follow-up OCT after stent implantation was performed in 100 patients (48 EES-treated lesions ...

    12. The Application of Extended Field Imaging to Optical Coherence Tomography

      The Application of Extended Field Imaging to Optical Coherence Tomography
      Since its invention, optical coherence tomography (OCT) has made remarkable advancements in both image resolution and acquisition speed. 1,2 With improvements in both hardware and software, higher resolution and less noisy retinal cross-sectional images can be obtained noninvasively. 3 Recent improvements to commercially available OCT systems have also included increasing scan length. For example, most spectral-domain OCT machines provide line scans that are approximately 9 mm in length. Therefore ...
