    2. Automated Deformation-Based Analysis of 3D Optical Coherence Tomography in Diabetic Retinopathy

      Automated Deformation-Based Analysis of 3D Optical Coherence Tomography in Diabetic Retinopathy
      Diabetic retinopathy (DR) is a significant microvascular complication of diabetes mellitus and a leading cause of vision impairment in working age adults. Optical coherence tomography (OCT) is a routinely used clinical tool to observe retinal structural and thickness alterations in DR. Pathological changes that alter the normal anatomy of the retina, such as intraretinal edema, pose great challenges for conventional layer-based analysis of OCT images. We present an alternative approach ...

    3. Impaired Retinal Vascular Reactivity in Diabetic Retinopathy as Assessed by Optical Coherence Tomography Angiography

      Impaired Retinal Vascular Reactivity in Diabetic Retinopathy as Assessed by Optical Coherence Tomography Angiography
      Purpose : To assess retinal vascular reactivity in healthy controls and subjects with diabetic retinopathy (DR). Methods : A total of 22 healthy control eyes and 16 eyes with DR were enrolled. Images were acquired using a commercially available swept-source optical coherence tomography angiography (SS-OCTA) system. Three conditions were tested for each patient (hyperoxia, hypercapnia, and room-air) by employing a non-rebreathing apparatus that delivered appropriate gas mixtures (100% O 2 , 5% CO ...

    4. Diagnostic Capability of 3D Peripapillary Retinal Volume for Glaucoma Using Optical Coherence Tomography Customized Software

      Diagnostic Capability of 3D Peripapillary Retinal Volume for Glaucoma Using Optical Coherence Tomography Customized Software
      Prcis: The diagnostic capability of peripapillary retinal volume is similar to peripapillary retinal nerve fiber layer thickness for diagnosing glaucoma, but with fewer artifacts. Purpose: To compare the diagnostic capability of three-dimensional (3D) peripapillary retinal volume (RV) versus two-dimensional (2D) peripapillary retinal nerve fiber layer (RNFL) thickness for open-angle glaucoma . Patients and Methods: A retrospective cross-sectional analysis was conducted. A total of 180 subjects [113 open-angle glaucomas (OAG), 67 normal ...

    5. Anterior Segment Optical Coherence Tomography: Applications for Clinical Care and Scientific Research

      Anterior Segment Optical Coherence Tomography: Applications for Clinical Care and Scientific Research
      Anterior segment optical coherence tomography (ASOCT) is a non-contact imaging technique that produces high-resolution images and quantitative measurements of the anterior segment and its anatomical structures. There has been rapid development of OCT technology over the past 2 decades, with the transition from time-domain to Fourier-domain OCT devices. By integrating these advancements in OCT technology, AS-OCT devices have evolved into versatile clinical and research tools for studies of the anterior ...

    8. Diagnostic Performance of Macular Versus Peripapillary Vessel Parameters by Optical Coherence Tomography Angiography for Glaucoma

      Diagnostic Performance of Macular Versus Peripapillary Vessel Parameters by Optical Coherence Tomography Angiography for Glaucoma
      Purpose : To compare the diagnostic ability of the vessel parameters in macular and peripapillary regions measured using spectral-domain optical coherence tomography angiography (SD-OCTA) in differentiating primary open-angle glaucoma (POAG) from healthy eyes. Methods : POAG patients and healthy subjects underwent 6 6-mm scans centered on the macula and optic nerve head. Commercially available automatic segmentation created en face images from SD-OCTA of the superficial retinal layer (SRL) of the macular (m ...

    9. Changes In Retinal Thickness On Optical Coherence Tomography From Intravitreal Melphalan

      Changes In Retinal Thickness On Optical Coherence Tomography From Intravitreal Melphalan
      PURPOSE To quantify changes in central retinal thickness (CRT) on intraoperative spectral domain optical coherence tomography (SD-OCT) pre- and post- intravitreal melphalan (IVM) injection for retinoblastoma (Rb). METHODS Retrospective review of 5 eyes of 5 patients with Rb without macular tumor involvement treated with IVM injection for vitreous seeding. Automated and manual ETDRS measurements of CRT sub-foveally were derived from SD-OCT images pre- and post- IVM injection. RESULTS Mean age ...

    10. Stereological Method in Optical Coherence Tomography for In Vivo Evaluation of Laser-Induced Choroidal Neovascularization

      Stereological Method in Optical Coherence Tomography for In Vivo Evaluation of Laser-Induced Choroidal Neovascularization
      BACKGROUND AND OBJECTIVE: To evaluate a stereological method in optical coherence tomography (OCT) as an in vivo volume measurement of laser-induced choroidal neovascularization (L-CNV) lesion size. PATIENTS AND METHODS: Laser photocoagulation was applied in rats to rupture Bruch's membrane and induce L-CNV. In vivo OCT images of neovascular lesions were acquired with a spectral-domain OCT system at days 0, 3, 7, 10, and 14 after laser surgery. A stereological ...
