    2. Different serial changes in the neointimal condition of sirolimus-eluting stents and paclitaxel-eluting stents: an optical coherence tomographic study

      Different serial changes in the neointimal condition of sirolimus-eluting stents and paclitaxel-eluting stents: an optical coherence tomographic study
      Aims: Detailed long-term changes of the neointima in sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES) are still unclear. Methods and results: We consecutively enrolled 14 patients (18 SES) and 12 patients (13 PES) who underwent optical coherence tomography (OCT) serially at eight months and 18 months after stent implantation. For 18 SES and 13 PES, OCT was used to visualise 2,486 and 1,361 stent struts at the eight-month ...

    3. Diagnostic Evaluation of Ocular Toxocariasis Using High-Penetration Optical Coherence Tomography

      Diagnostic Evaluation of Ocular Toxocariasis Using High-Penetration Optical Coherence Tomography
      Purpose: To study a case with intraretinal Toxocara larvae in a granuloma using high-penetration optical coherence tomography (HP-OCT). Methods: A 50-year-old man, who was referred to our clinic with ocular toxocariasis, initially presented with granuloma formation in the retina. We followed the treatment-associated changes in the toxocariasis lesion by a series of examinations using HP-OCT before and after a systemic corticosteroid and anthelmintic therapy. Results: The posterior pole granuloma initially ...

    4. Dynamic Analysis of Mental Sweating by the Time-Sequential Piled-Up En-Face OCT Images

      Dynamic Analysis of Mental Sweating by the Time-Sequential Piled-Up En-Face OCT Images
      In this paper, the dynamic analysis of mental sweating for sound stimulus of a few tens of eccrine sweat glands is per- formed by the time-sequential piled-up en-face optical coherence tomography (OCT) images with the frame spacing of 3.3 sec. In the experiment, the amount of excess sweat can be evaluated simultaneously for a few tens of sweat glands by piling up of all the en-face OCT images. Strong ...

    8. Three-dimensional high-speed optical coherence tomography system using KTN swept light source

      Three-dimensional high-speed optical coherence tomography system using KTN swept light source
      Three-dimensional (3D) optical coherence tomography (3D-OCT) has attracted attention for visualising complex structures in the biomedical field. In this reported work, a high-speed 3D-OCT system is developed, which is based on a high-speed swept light source and aMach-Zehnder interferometer with a high-speed photodetector. The light source, incorporating a KTa 1-x Nb x O 3 electro-optic deflector, operates at a repetition rate of 200 kHz and enables high-speed data acquisition. As ...

    9. High-Speed Optical Coherence Tomography System Using a 200-kHz Swept Light Source with a KTN Deflector

      High-Speed Optical Coherence Tomography System Using a 200-kHz Swept Light Source with a KTN Deflector
      We demonstrate a high-speed swept-source optical coherence tomography (SS-OCT) system, which is based on a high- speed swept light source and a Mach-Zehnder interferometer with a high-speed photodetector. The light source is an external-cavity laser tuned by a KTN electro-optic deflector, which exhibits a very fast response and large deflection. The scanning wavelength range is almost 80 nm up to 200 kHz with a 400-V deflector driving voltage. The system ...

    10. 3-D Choroidal Thickness Maps from EDI-OCT in Highly Myopic Eyes

      3-D Choroidal Thickness Maps from EDI-OCT in Highly Myopic Eyes
      Purpose: Myopic chorioretinal atrophy is a debilitating condition that causes severe loss of primary vision. However, its mechanisms and pathologic course are not well understood. We performed volumetric measurements of the posterior choroid via three-dimensional analysis of the choroid in patients with high myopia to understand its structure, and we compared the measurements with those of normal subjects. Methods: Twenty-five highly myopic but otherwise normal eyes and 25 nonmyopic eyes ...
