Active clinical trials for "Edema"

The investigators would like to investigate the efficacy of more frequent treatment with Lucentis for subjects with persistent diabetic macular edema despite standard dosing regimen.

Assess prophylactic efficacy of topical non-steroidal anti-inflammatory drops in preventing macular edema. Patient undergoing uncomplicated cataract surgery will be enrolled and randomized to nepafenac, ketorolac, or placebo. Follow-up will occur at 1 month with ocular coherence tomography (OCT).

Immersion pulmonary edema (IPE) is a condition in which fluid fills the lungs during diving or swimming, particularly in cold water. Some individuals appear to be predisposed to developing IPE. DNA samples will be collected and stored, in order to compare the genetic profiles of individuals who have experienced IPE with those who have not. In a few individuals who have experienced IPE, we plan to measure the effects of cold water immersion on the blood pressure, cardiac output and the pressures in the pulmonary artery. These will be compared with similar measurements already obtained from normal individuals.

Macular Edema (Swelling of a particular site of the retina) can become a significant problem for Diabetics undergoing Cataract surgery. And a significant number of people who undergo Cataract surgery each year are diabetics. And when you multiply these two factors together you are left with a significant number of people who do not gain as much vision as their peers. Diabetics who develop Macular Edema actually can loose some vision after surgery and when you follow them up, they don't gain as much vision. This Study aims to prevent such an event from happening and therefore allow Diabetics to gain as much vision as they can from cataract surgery. This study will use Dexamethasone injected intravitreally (into the gel of the eye) at the end of cataract extraction to control Macular edema brought about by surgery. The main outcome is the central retina thickness and retinal volume as measured by Optical Coherence Tomography. Secondary outcomes are BCVA and incidence of Laser Treatment. Other Drugs, life Bevacizumab and Pegaptanib, have been used for this purpose but they are expensive and have potential systemic side-effects due to anti-VEGF (vascular endothelial growth factor) actions. Dexamethasone has been used in the eye for decades and is short-lived, minimizing possible systemic effects. Moreover, this drug is at least 15x cheaper than the previously mentioned ones and therefore has tremendous benefit for developing countries. We seek an alternative drug that can reduce or prevent Macular edema at a less expensive and safer way.

This study looks to continue the study of anti-vegf therapy in patients with macular edema, and compare it to an anti-inflammatory therapy and a combined Anti-vegf and anti-inflammatory.

Patients with proliferative diabetic retinopathy or clinically significant diabetic macular edema requiring surgical intervention will receive a pre-operative injection of Macugen. An initial, pre-injection vitreous tap will be done in order to provide baseline VRGF 165 and cytokine levels. At the onset of the vitrectomy, a second vitreous sample will be taken to obtain intra-operative levels of Macugen, VEGF 165 and cytokines.

The purpose of this study is to investigate the safety and tolerability of three dose strengths of the study drug in subjects with post cataract extraction macular edema.

Macular edema is the main cause of low vision in diabetics. They continue looking for new treatment alternatives. The nutritional supplement Alzer, is a powerful antioxidant that together with Diamel, a supplement that has shown efficacy in metabolic control, could be a therapeutic option. Objective: To evaluate the therapeutic efficacy of the Alzer Diamel combination in mild and moderate macular edema. Material and method: A randomized double-blind phase II clinical trial versus placebo will be conducted in 64 patients, who will be randomly assigned to two groups, one will receive Alzer + Diamel and another will receive placebo from Alzer and Diamel. All patients will undergo clinical, biochemical and ophthalmological evaluation during the study.

This trial is testing the effectiveness of a single oral dose of sildenafil (50 mg) taken 1 hour before a provocative event on the subsequent development of swimming-induced pulmonary edema.

During surgery, blood leaking from damaged blood vessels spread to the periorbital area may cause periorbital edema and ecchymosis after anterior craniotomy. This study was carried out to determine the effects of the cold application and the local heparinoid on periorbital edema and ecchymosis after craniotomy.
