    6. Analysis of the Variation in Thickness of Per-papillary Retinal Optic Nerve Fibres in Professional Rugby Players

      Analysis of the Variation in Thickness of Per-papillary Retinal Optic Nerve Fibres in Professional Rugby Players

      The main hypothesis is that exposure to repeated shocks is associated with a greater decrease in the thickness of optical nerve fibres. In order to show a association between the occurrence of concussions (in number and severity) and the variation in the thickness of the retinal nerve fibre layer, all participating rugby players will have an ophthalmologic examination (OCT and (retinophotography) at the beginning and end of the Rugby season.

    7. Apelin as a Potential Treatment for Chronic Kidney Disease

      Apelin as a Potential Treatment for Chronic Kidney Disease

      Chronic kidney disease (CKD) affects 8-16% of the world's population, and is independently associated with cardiovascular disease (CVD). As renal function declines, rates of major adverse cardiovascular events, cardiovascular and all-cause mortality increase. In addition to hypertension, increased arterial stiffness is characteristic of CKD, a marker of CVD risk, and an independent predictor of mortality in CKD patients. The endothelium is an important regulator of arterial stiffness, and endothelial dysfunction is a feature of CKD and a predictor of CVD. Current treatment of CKD is limited and aims to reduce blood pressure and proteinuria through the use of angiotensin ...

    8. Role of Intracoronary Imaging in Plaque Identification

      Role of Intracoronary Imaging in Plaque Identification

      NSTE-ACS patients are more likely to exhibit high-risk plaque characteristics in non-culprit lesions. Both IVUS and OCT imaging techniques interact in a complementary manner to provide morphological characterization of the atherosclerotic coronary plaques and help identification of high-risk vulnerable plaques. Using morphological parameters obtained from OCT and IVUS, a new plaque vulnerability score will be established for more precise definition of the most vulnerable plaques that carry the greatest risk of rupture and subsequent detrimental clinical outcomes in the future. Such score might help in targeting these plaques with certain therapeutic interventions aiming to their stabilization.

    9. Optical Coherence Tomography Angiography (OCT-A) and Central Serous Chorioretinopathy (CSC) (OPACITY)

      Optical Coherence Tomography Angiography (OCT-A) and Central Serous Chorioretinopathy (CSC) (OPACITY)

      Optical Coherence Tomography Angiography (OCT-A) is a noninvasive imaging technique that allows one to see blood vessels in the retina. The investigating team used this approach in patients with acute, recurrent and persistent subtypes of Central Serous Chorioretinopathy (CSC) to check for possible Choriocapillaris hypoperfusion. The presence or absence of these microvascular changes was explored in both eyes of the patients and compared to a control group of healthy volunteers. The possibility of a correlation between Choriocapillaris flow deficits, age and spontaneous resolution of serous retinal detachment was also evaluated. This study was conducted in an effort to improve one ...

    10. Infracyanine Green vs Brilliant Blue G in Macular Hole Inverted Flap Surgery: A Swept Source OCT Analysis.

      Infracyanine Green vs Brilliant Blue G in Macular Hole Inverted Flap Surgery: A Swept Source OCT Analysis.

      This study will compare by swept-source optical coherence tomography (SS-OCT) the retinal morphology after inverted internal limiting membrane (I-ILM) flap vitreoretinal surgery for medium-to-large macular holes using infracyanine green (IFCG) vs brilliant blue G (BBG) dyeing. It is a single-center prospective, randomized study. One group of patients will undergo I-ILM vitrectomy with IFCG staining, the other vitrectomy with BBG staining. Postoperative six-month corrected distance visual acuity, macular hole closure rate, and SS-OCT parameters will be compared and statistically analyzed. The aim of the study is to verify if these parameters can be negatively affected by toxicity related to the use ...

    16. WF and Pr OCTA in Diabetic Retinopathy

      WF and Pr OCTA in Diabetic Retinopathy

      Diabetic retinopathy (DR) is a leading cause of vision loss in working-age Americans. Capillary damage from hyperglycemia causes vision loss through downstream effects, such as retinal ischemia, edema, and neovascularization (NV). Proper screening and timely treatment with laser photocoagulation and anti-vascular endothelial growth factor (VEGF) injections can minimize morbidity. In the last decade, clinicians have been able to use objective structural data from optical coherence tomography (OCT) to guide the treatment of diabetic macular edema. Other aspects of care, however, still largely depend on subjective interpretation of clinical features and fluorescein angiography (FA) to determine the disease severity and treatment ...

    17. Monitoring Large Vessel Vasculitis With PET/MR Imaging

      Monitoring Large Vessel Vasculitis With PET/MR Imaging

      Large vessel vasculitis (LVV) causes blood vessel inflammation leading to pain, fatigue and complications such as aneurysm formation and stroke. Treatments used can have significant side-effects. Doctors find it difficult to determine when to start and stop treatment, often leading to over- or under-treatment. A new test is required to determine disease activity that will guide treatment more accurately. This study will recruit participants with active LVV from throughout Scotland in order to assess the ability of two new types of scan - positron emission tomography with magnetic resonance imaging (PET/MR) and retinal optical coherence tomography (OCT) - to determine disease ...

      The Use of Fractional Ablative CO2 Laser vs Control on Acute Traumatic Injuries to Prevent Scar Formation

      Surgical standard for treating traumatic burn injury scarring is to wait one year following the initial assault prior to beginning treatment. This study investigates the use of fractional ablative CO2 laser when begun within 3 months of a traumatic burn injury and it's impact on scar formation compared to the control. We hypothesized that early intervention would substantially mitigate the formation of scar tissue and help restore more normal appearing skin.
