    2. Associations between preoperative OCT parameters and visual outcome 3 months postoperatively in patients undergoing vitrectomy for idiopathic epiretinal membrane

      Associations between preoperative OCT parameters and visual outcome 3 months postoperatively in patients undergoing vitrectomy for idiopathic epiretinal membrane
      Purpose To evaluate the effect of preoperative optical coherence tomography (OCT) features on postoperative visual acuity and change in acuity after epiretinal membrane (ERM) surgery. Methods This was a retrospective consecutive case series of patients with symptomatic idiopathic ERMs who underwent vitrectomy and membrane peel between 2008 and 2013. The main outcomes were postoperative letter score and change in letter score. The association between visual acuity and OCT features was ...

    3. Optical coherence tomography-guided percutaneous coronary intervention in pre-terminal chronic kidney disease with no radio-contrast administration

      Optical coherence tomography-guided percutaneous coronary intervention in pre-terminal chronic kidney disease with no radio-contrast administration
      A 67-year-old man with advanced chronic kidney disease (CKD) (creatinine = 4.5 mg/dL, eGFR = 13 mL/min/1.73 m 2 ) not requiring haemodialysis presented with progressive angina. Diagnostic angiography with ultra-low radio-contrast volume (12 mL, contrast volume/eGFR ratio 1) revealed significant stenosis in the left anterior descending (LAD) artery ( Panel A ). The lesion was haemodynamically significant (fractional flow reserve: 0.77). Post-angiography, the

    4. Optical coherence tomography for serial in vivo imaging of aortic plaque in the rabbit: a preliminary experience

      Optical coherence tomography for serial in vivo imaging of aortic plaque in the rabbit: a preliminary experience
      Background In this pilot feasibility study, we aimed to establish a reproducible means of performing serial optical coherence tomography (OCT) procedures in the abdominal aorta of the cholesterol-fed rabbit. Methods Eight cholesterol-fed New Zealand White rabbits were assigned to abdominal aortic balloon injury at baseline (n=6) or as controls (n=2). Three of the balloon injured rabbits received statins from weeks 6 to 12 post balloon injury. OCT of ...

    5. Comparison of two dimensional quantitative coronary angiography (2D-QCA) with optical coherence tomography (OCT) in the assessment of coronary artery lesion dimensions

      Comparison of two dimensional quantitative coronary angiography (2D-QCA) with optical coherence tomography (OCT) in the assessment of coronary artery lesion dimensions
      Objectives There is limited data on how well 2D-QCA and OCT agree with each other for measurement of coronary artery lumen dimensions. We aimed to assess the agreement between the two modalities. Methods Patients undergoing OCT for assessment of coronary artery lesions were reviewed. Minimum luminal diameter (MLD), proximal reference diameter and distal reference diameter were measured for each lesion prior to stenting. Results OCT was performed in 64 patients ...

    7. Advanced imaging in COPD: insights into pulmonary pathophysiology

      Advanced imaging in COPD: insights into pulmonary pathophysiology
      Chronic obstructive pulmonary disease (COPD) involves a complex interaction of structural and functional abnormalities. The two have long been studied in isolation. However, advanced imaging techniques allow us to simultaneously assess pathological processes and their physiological consequences. This review gives a comprehensive account of the various advanced imaging modalities used to study COPD, including computed tomography (CT), magnetic resonance imaging (MRI), and the nuclear medicine techniques positron emission tomography (PET ...

    9. The investigation of acute optic neuritis: a review and proposed protocol

      The investigation of acute optic neuritis: a review and proposed protocol
      Optic neuritis is an inflammatory optic neuropathy that affects many patients with multiple sclerosis (MS) at some point during their disease course. Differentiation of acute episodes of MS-associated optic neuritis from other autoimmune and inflammatory optic neuropathies is vital for treatment choice and further patient management, but is not always straightforward. Over the past decade, a number of new imaging, laboratory and electrophysiological techniques have entered the clinical arena. To ...

    10. Quality control for retinal OCT in multiple sclerosis: validation of the OSCAR-IB criteria

      Quality control for retinal OCT in multiple sclerosis: validation of the OSCAR-IB criteria
      Background: Retinal optical coherence tomography (OCT) permits quantification of retinal layer atrophy relevant to assessment of neurodegeneration in multiple sclerosis (MS). Measurement artefacts may limit the use of OCT to MS research. Objective: An expert task force convened with the aim to provide guidance on the use of validated quality control (QC) criteria for the use of OCT in MS research and clinical trials. Methods: A prospective multi-centre ( n = 13 ...

    11. Symmetry of Retinal Parameters Measured by Spectral-domain OCT in Normal Young Adults

      Symmetry of Retinal Parameters Measured by Spectral-domain OCT in Normal Young Adults
      Purpose: To determine interocular differences in retinal parameters in a population of young adults using spectral-domain optical coherence tomography. Methods: In the Sydney Adolescent Vascular Eye Study, young adults aged 16 to 19 years received a standardized eye examination encompassing retinal photography, spectral-domain optical coherence tomography (Cirrus HD-OCT; Carl Zeiss Meditec, Dublin, CA) and best-corrected visual acuity. Interocular differences in retinal nerve fiber layer (RNFL) and macular parameters together with ...
