Active clinical trials for "Edema"

The prevalence of diabetes mellitus has increased significantly in Hong Kong for the past decade [1]. Diabetic macular edema is one of the most common causes of vision loss in patients suffering from diabetes mellitus [3]. Before the introduction of anti-vascular endothelial growth factor agents, laser photocoagulation has been the mainstay treatment for patients with diabetic macular edema. There are two types of laser treatment modalities, namely focal laser, which can be applied either in a grid pattern over a region of macular edema or to selected microaneurysms, and subthreshold micropulse laser. Only one meta-analysis published in 2016 [16] had previously demonstrated superiority of micropulse laser over focal laser, while other studies showed no clinically significant differences between the two lasers. Nevertheless, micropulse laser had been proven to cause no structural changes to the retina and choroid, as opposed to focal laser. Optical coherence tomography angiography (OCT-A) is a new, non-invasive imaging technique that allows a clear, depth-resolved visualization of the retinal and choroidal microvasculature in the macular region [22]. A recent case series study [17] has demonstrated early changes of retinal vasculature on OCT-A images after micropulse laser for diabetic macular edema. Another cross-sectional study [18] showed choriocapillaries alterations in some of the patients after receiving focal laser. We would like to compare the changes of different OCT-A parameters for patients receiving either type of laser, and hence evaluating their efficacy. We propose to take OCT-A images for patients before laser, 1-, 3- and 6-months post-laser based on the results of a recent case series [17]. We will analyse the OCT-A images with MATLAB software and compare the changes in different parameters between both lasers.

This study is a prospective, non-interventional, multicenter, open-label study in nAMD and DME patients being treated with brolucizumab according to the EU SmPC. An observational study design, without a strict, mandated visit schedule or mandated treatment regimen was chosen as the most appropriate to collect available data in a real life setting. For that reason, this NIS does not impose a therapy protocol, diagnostic/therapeutic procedure or a visit schedule. The diagnostic or monitoring procedures are only those ordinarily applied to the therapeutic strategy and to routine clinical care and will take place as per investigator's discretion. This includes e.g. visit frequency, injection frequency and types of assessments performed - only data from routine medical practice will be collected as part of the study.

Imaging endolymphatic hydrops with 7T Sodium Imaging and 1.5 T gadolinium enhanced imaging: a comparison of diagnostic outcomes with 3T MRI Duration of study 24 months Study design Prospective cohort study Number of patients 16 patients To evaluate whether imaging both 1.5T and 3T have an equivalent performance in terms of diagnosing MD ears with delayed post gadolinium enhanced MRI (applying quantitative and semi-quantitative analysis) To compare the diagnostic performance of Sodium Imaging at 7T (applying semi-quantitative analysis) with that of delayed post gadolinium enhanced 3T MRI in distinguishing symptomatic from asymptomatic Meniere's Disease (MD) ears.

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).

Title: Intravitreal faricimab in diabetic macular edema with limited response to aflibercept Purpose: The purpose of this investigator initiated study is to identify the effects of intravitreal faricimab on recurrence-free treatment intervals and morphological features in diabetic macular edema (DME) in which the Optical coherence tomography (OCT) guided treatment interval failed to be extended to 6 weeks intervals in a treat and extend regimen using aflibercept. Objectives: The primary objective is to evaluate the proportion of patients with an increased maximum treatment interval with intravitreal faricimab (compared to previous 4-week interval under aflibercept) in an OCT guided treat and extend regimen at month 6 and 12. (for further outcome measures see section Objectives)

The current protocol is composed of two studies. The first study is designed to carefully evaluate the safety of high-dose salmeterol/fluticasone administration over 7 days, as well as the efficacy of the study drug to increase exercise performance, in healthy individuals exercising under hypoxic, simulated high-altitude conditions (Phase 1/2a study). The second study will examine sensitive measures of cardiopulmonary function using invasive cardiopulmonary testing, in both HAPE-sensitive and HAPE-resistant individuals, to assess the potential efficacy of salmeterol/fluticasone to prevent pulmonary edema and to enhance exercise capacity (Phase 2a) in these individuals.

A prospective, randomized, single-masked study evaluating the ocular efficacy and safety of two doses of the EYP-1901 intravitreal insert compared to aflibercept

The goal of this clinical trial is to assess the efficacy and safety of multiple doses of foselutoclax (UBX1325) in patients with Diabetic Macular Edema. The main question[s] the study aims to answer are: Assess the efficacy of foselutoclax compared to aflibercept Assess the safety and tolerability of foselutoclax

The aim of this study is to compare the changes in upper airway edema with the preoperative and postoperative ultrasonographic measurements of patients who undergo pobotic prostatectomy in the trendelenburg position. The secondary aim is to investigate the correlation between OSAS risk levels determined by the STOP-BANG score in the preoperative period of the patients participating in the study airway ultrasound measurements and postoperative critical respiratory events in the preoperative and postoperative period.

This multicenter, non-randomized, open-label, multiple-dose-escalation and dose-expansion study will investigate the safety, tolerability, pharmacokinetics and efficacy of ASKG712 following intravitreal administration in patients with diabetic macular edema (DME).
