Filter by:The Farseeing Study will explore long-term effectiveness, safety, and treatment patterns among patients being treated with faricimab in real-world, routine clinical practice in China. It is a primary data collection, non-interventional, prospective and retrospective, multi-center study designed to collect real-world, long-term data to gain clinical evidence on faricimab, by observing cohorts of patients with neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), and retinal vein occlusion (RVO) who are receiving treatment with faricimab.
This prospective observational study investigates the potential of point-of-care ultrasonography of the optic nerve sheath diameter (ONSD) to rule out papilledema in patients with suspected hypertensive emergency. The primary focus is on assessing ONSD sensitivity in identifying papilledema (hypertensive retinopathy grade 4), while secondary endpoints include hypertensive retinopathy grade 3, hypertensive encephalopathy, and the need for intravenous rapid-acting medications to lower elevated blood pressure. This study aims to determine the diagnostic characteristics of this procedure for the diagnosis of hypertensive retinopathy, thus assessing its potential as a screening tool to rule out hypertensive retinopathy by the acute internal medicine doctor.
50 patients with verified new-onset Idiopathic Intracranial Hypertension are randomly allocated to standard weight management (dietician counselling) or trial intervention consisting of subcutaneous injections with Semaglutide for 10 months combined, in the initial 8 weeks following diagnosis, with a Very Low Calorie-Diet (max 800 kcal/day)
In this project, the investigators propose to test effectiveness of a daily nutraceutical supplement containing bioactive B vitamins to mitigate optic disc edema in astronauts. The proposed countermeasure is intended to maximize functioning of the one-carbon metabolic pathway to provide enough substrate and cofactors to overcome any genetic differences that may impact the efficiency of enzyme function. By optimizing the pathway, this will 1) optimize endothelial function by increasing eNOS coupling and nitric oxide synthesis and 2) optimize collagen firmness and elasticity in the sclera and lamina cribrosa, and 3) minimize changes in total retinal thickness during and after flight. The protocol includes assessments of ocular health and function, along with determinants of vascular endothelial function, advanced glycation end products, and nutritional status and one carbon biochemistry. These additional measures will be critical for the further definition of the causes of optic disc edema in some astronauts after long-duration space flight, and in understanding the effect of the countermeasure. Finally, the supplemented subjects in this study will be compared against total retinal thickness data from previously flown astronauts known to have not taken supplements during their missions.
Comparison of high-resolution optical coherence tomography (High-Res-OCT) to conventional imaging modalities for the diagnosis of eye diseases
Prospective interventional study on 60 eyes of resistant diabetic macular edema and central retinal vein occlusion that will receive suprachoroidal injection of Triamcinolone Acetonide (SCTA).
Assessing the efficacy and safety of DEXTENZA, sustained release dexamethasone 0.4 mg inserts following 27 gauge vitrectomy with internal limiting membrane peel
The presence of optic disc swelling at the fundus is a non-specific clinical sign that can occur in many ophthalmologic, neuro-ophthalmologic or encephalic pathologies. The diagnostic range is vast, including inflammatory pathologies of the optic nerve, infiltrative or compressive orbital pathologies, idiopathic or secondary intracranial hypertensions, not to mention the pseudo optic disc swelling found in drüsens. MRI is increasingly being used as a first-line examination to obtain an etiologic diagnosis in a patient with optic disc swelling. It allows a rapid diagnosis to be made in cases of inflammatory pathology or compressive or infiltrative pathology. It can provide very suggestive elements in the case of intracranial hypertension. It appears to be potentially useful in diagnosing ischemic optic neuropathy or in directing towards an etiological diagnosis of Giant Cell Arteritis. The development of new high-resolution MRI sequences has made it possible to obtain extremely fine resolutions of a few hundred microns in the plane. Apart from a few clinical cases and small series, there is no precise evaluation of the interest of these new sequences in the positive and etiological diagnosis of ophthalmological, neuro-ophthalmological and encephalic pathologies responsible for the presence of optic disc swelling. The objective of our study is therefore to evaluate the diagnostic contribution and the gain in diagnostic confidence provided by these new sequences in the context of pathologies manifesting as optic disc swelling.
This is a search strategy for determining the prevalence of ocular complications in inflammatory rheumatic diseases for the purposes of a meta analysis.
