Active clinical trials for "Macular Edema"

This study is a multicenter, prospective, observational study to evaluate the long-term safety of OZURDEX® in patients with macular oedema following central retinal vein occlusion (CRVO) or branch retinal vein occlusion (BRVO) or patients with non-infectious posterior segment uveitis in real-world clinical practice.

This multicenter observational study will assess the efficacy and tolerability of OZURDEX® in clinical practice, and will assess the time at which patients are considered for retreatment.

The purpose of this research is to evaluate the effectiveness of vitrectomy for the treatment of diabetic macular edema. Diabetes is known to cause retinal blood vessels to leak, leading to swelling of the central retina (macula), and decreased vision. Removing the vitreous gel with vitrectomy surgery is known to decrease the swelling caused by diabetes. Diabetic retinopathy is often treated with laser or injections of medicine in to the eye.

This study will evaluate the efficacy of Ozurdex® as prescribed in clinical practice in France for the treatment of Diabetic Macular Edema (DME).

Diabetic retinopathy(DR) is a sight threatening condition that occurs in persons with diabetes. DR arises as a consequence of damage to the retinal blood vessels and is related to the high and fluctuating sugar levels in the blood stream. An eye with DR will have abnormal appearing retinal blood vessels which become engorged and dilated, leaky and fragile or undergo closure. The net result is a picture of haemorrhage and or ischaemia (lack of blood supply). A particular feature of DR is the accumulation of fluid in the macula which is the central part of the retina and responsible for detailed eye sight. This peculiar form of DR is called Diabetic Macular Oedema (DMO). DMO can occur in isolation without other features of DR. DMO is commoner in type 2 diabetes where insulin resistance and abnormalities of blood fats are found. The investigators wish to study DR and DMO using high resolution retinal imaging and functional tests in normal participants, those participants with diabetes without any overt signs of disease and those with DR and DMO in order to understand how the condition develops and whether there are any unique risk factors that can be identified

The objective of this retrospective chart review is to evaluate drug utilization, usage patterns and indication of effectiveness Eylea in the routine clinical (real-life) management of patients who suffer from ME (Macular Edema), secondary to CRVO (Central Retinal Vein Occlusion), and who started treatment with Eylea for this indication.

This project aims to validate a predictive model of diabetic retinopathy progression to clinically significant macular edema (CSME) needing photocoagulation and/or vision loss. The Coimbra Predictive Model (CPM), based on retinal thickness, microaneurysms number, HbA1C and LDL levels, established on a set of 52 diabetic patients, will be tested on a population of 400 patients/eyes to be enrolled into the study. These patients will perform 2 visits at 6-month interval (V0 and V6) to classify each patient into one of the 3 previously established phenotypes. Two years after (V24) patients will be reexamined. The occurrence of end-points, achieved by the patients, are expected to validate our predictive model.

This study will look for the presence in blood of a substance called vascular endothelial growth factor (VEGF) in patients with uveitis (eye inflammation). It will also look for this substance in eye fluid samples taken from patients with uveitis who are undergoing eye surgery. Some patients with uveitis experience some vision loss during an inflammatory attack because of swelling (edema) in a particular area of the retina called the macula, which is involved in visual acuity. It may be that VEGF is involved in the development of macular edema. Patients with uveitis who participate in this study will have about 10 cc (2 teaspoons) of blood drawn to be examined for VEGF. They will also undergo a procedure called fluorescein angiography to look at the blood vessels of the eye. A dye called sodium fluorescein is injected into the blood stream through a vein. After the dye reaches the blood vessels of the eye, photographs are taken of the retina. In addition, patients with uveitis who are undergoing eye surgery will have a tissue specimen (either aqueous fluid or vitreous gel) collected for examination for the presence of VEGF.

The Navilas® micropulse laser can be used to treat patients with macular edema and good visual acuity, which therefore do not fall within the indications for conventional treatments by intravitreal injections. The CHU Brugmann Hospital is the only center to own this laser in Belgium.This study aims to evaluate the efficacy of this laser.

ADMIRE was a prospective, observational cohort study of patients with diabetic macular edema (DME). Efficacy was assessed by change in best-corrected visual acuity (BCVA) and central retinal thickness (CRT) from baseline to months 12, 24 and 36 after treatment with intravitreal aflibercept in treatment-naïve patients and previously treated patients. Safety was evaluated by recording any patients-reported events.
