    1. Clinical Assessment of Scleral Canal Area in Glaucoma Using Spectral Domain Optical Coherence Tomography

      Clinical Assessment of Scleral Canal Area in Glaucoma Using Spectral Domain Optical Coherence Tomography

      Purpose To investigate anterior scleral canal (ASC) area in the eyes with glaucoma using spectral-domain optical coherence tomography (SD-OCT). Design Cross-sectional study. Methods This study included 206 eyes of 103 patients with glaucoma classified as 66 eyes of 33 patients with unilateral glaucoma and 140 eyes of 70 patients with bilateral glaucoma. Radial scan enhanced depth imaging SD-OCT centered on the optic disc was performed, and parameters that present ASC area such as ASC opening and the largest ASC area were obtained in each eye. The largest ASC area was the largest cross-sectional area of the ASC region identified between ...

    2. Lamina Cribrosa Depth Variation Measured by Spectral-Domain Optical Coherence Tomography Within and Between Four Glaucomatous Optic Disc Phenotypes

      Lamina Cribrosa Depth Variation Measured by Spectral-Domain Optical Coherence Tomography Within and Between Four Glaucomatous Optic Disc Phenotypes

      Purpose : To study lamina cribrosa (LC) depth variation measured by spectral-domain optical coherence tomography (SD-OCT) in four glaucomatous optic disc phenotypes. Methods : In this cross-sectional study, 59 normal eyes and 180 open-angle glaucoma (OAG) eyes were grouped into 56 focally injured discs (FI), 30 generalized enlargement of the optic cup discs (GE), 69 myopic glaucomatous discs (MY), and 25 senile sclerotic discs (SS). They were imaged by enhanced depth imaging SD-OCT, obtaining multiple horizontal and vertical optic disc B-scans. Mean and maximum LC depths were measured relative to Bruch's membrane opening (BMO) and the anterior sclera (AS) reference planes ...

    3. Impact of Statin Therapy on Plaque Characteristics as Assessed by Serial OCT, Grayscale and Integrated Backscatter–IVUS

      Impact of Statin Therapy on Plaque Characteristics as Assessed by Serial OCT, Grayscale and Integrated Backscatter–IVUS

      Objectives: The purpose of this study was to evaluate the effect of statin treatment on coronary plaque composition and morphology by optical coherence tomography (OCT), grayscale and integrated backscatter (IB) intravascular ultrasound (IVUS) imaging. Background: Although previous studies have demonstrated that statins substantially improve cardiac mortality, their precise effect on the lipid content and fibrous cap thickness of atherosclerotic coronary lesions is less clear. While IVUS lacks the spatial resolution to accurately assess fibrous cap thickness, OCT lacks the penetration of IVUS. We used a combination of OCT, grayscale and IB-IVUS to comprehensively assess the impact of pitavastatin on plaque ...

    4. The fate of incomplete stent apposition with drug-eluting stents: an optical coherence tomography-based natural history study

      The fate of incomplete stent apposition with drug-eluting stents: an optical coherence tomography-based natural history study

      Aims To assess the fate of incomplete stent apposition (ISA) after deployment of sirolimus-eluting stents (SESs). Methods and results Thirty-two patients having intravascular ultrasound (IVUS)-guided PCI with SESs underwent assessment of stent deployment with quantitative coronary angiography, IVUS, and optical coherence tomography (OCT) pre-procedure, post-procedure, and at 10 months follow-up. Incomplete stent apposition was defined as separation of a stent strut from the inner vessel wall by >160 µm. At follow-up, 4.67% of struts with ISA at deployment failed to heal and 7.59% which were well apposed did not develop neointimal hyperplasia even after 10 months. Lesion ...
