Active clinical trials for "Macular Edema"

This study investigates the hypothesis that ranibizumab injection given into the eye is an efficacious and safe treatment option applied for swelling of the macula (site of sharp vision) in diabetes.

Evaluate the ability and accuracy of the Retinal Health Monitoring System - Retinal Thickness Module (RHMS - RTM).

The aim of this study is to determine whether fundus autofluorescence and macular pigment distribution in inflammatory and diabetic macular edema are altered.

This study will be a retrospective analysis of vitrectomy results in patients suffering from diabetic macular edema.

To describe the design, methodology and baseline characteristics of the Shanghai Cohort study of Diabetic Eye disease (SCODE) study, a community-based study to determine the prevalence and impact of diabetic eye disease, especially diabetic retinopathy (DR), in adults with diabetes living in Shanghai.

The containment associated with the VIDOC-19 pandemic creates an unprecedented societal situation of physical and social isolation. Our hypothesis is that in patients with chronic diseases, confinement leads to changes in health behaviours, adherence to pharmacological treatment, lifestyle rules and increased psychosocial stress with an increased risk of deterioration in their health status in the short, medium and long term. Some messages about the additional risk/danger associated with taking certain drugs in the event of COVID disease have been widely disseminated in the media since March 17, 2020, the date on which containment began in France. This is the case, for example, for corticosteroids, non-steroidal anti-inflammatory drugs but also for converting enzyme inhibitors (ACE inhibitors) and angiotensin II receptor antagonists (ARBs2). These four major classes of drugs are widely prescribed in patients with chronic diseases, diseases specifically selected in our study (corticosteroids: haematological malignancies, multiple sclerosis, Horton's disease; ACE inhibitors/ARAs2: heart failure, chronic coronary artery disease). Aspirin used at low doses as an anti-platelet agent in coronary patients as a secondary prophylaxis after a myocardial infarction can be stopped by some patients who consider aspirin to be a non-steroidal anti-inflammatory drug. Discontinuation of this antiplatelet agent, which must be taken for life after an infarction, exposes the patient to a major risk of a new cardiovascular event. The current difficulty of access to care due to travel restrictions (a theoretical limit in the context of French confinement but a priori very real), the impossibility of consulting overloaded doctors, or the cancellation of medical appointments, medical and surgical procedures due to the reorganization of our hospital and private health system to better manage COVID-19 patients also increases the risk of worsening the health status of chronic patients who by definition require regular medical monitoring. Eight Burgundian cohorts of patients with chronic diseases (chronic coronary artery disease, heart failure, multiple sclerosis, Horton's disease, AMD, haemopathic malignancy, chronic respiratory failure (idiopathic fibrosis, PAH) haemophilia cohort) will study the health impact of the containment related to the COVID-19 pandemic.

Correlation between changes observed in OCT and VA in patients with retinal vein occlusion whether the patient's VA improves when macular edema improves in OCT or not ??

there is no yet agreement about the best way to treat Diabetic Macular Edema (DME) the two options up to day are using Grid laser treatment Vs. Avastin injections or a combination of both in this study we want to compare the two attitudes.

This study aims to evaluate the influence and prognostic value of systemic factors (such as the cardiovascular and metabolic status) on the treatment response to anti-VEGF therapy in macular edema due to diabetes or retinal vein occlusion.

An increasing number of clinical studies on SD-OCT of ocular pathologies and potential new clinical applications has recently been published in the peer-reviewed literature. However, the successful use of SD-OCT in routine clinical use depends upon the diagnostic sensitivity, biometric accuracy and reliability of the SD-OCT machines. This prospective, comparative, observational study aims to evaluate the imaging quality and diagnostic performance of two commercially available SD-OCT machines for both the anterior and posterior segment of the eye.
