Active clinical trials for "Retinal Vein Occlusion"

This clinical trial is designed to compare ranibizumab in comparison with Dexamethasone implant® after 6 months of treatment. In the study arm Lucentis will be given monthly in a pro re nata scheme whereas the comparator Dexamethasone implant is given once at Month 0 with sham injections PRN afterwards.

Central retinal vein occlusion is a leading cause of severe visual impairment. Until now, no treatment has been available to improve visual acuity. The present study intends to investigate if intravitreal bevacizumab can improve visual acuity as compared to sham-treated control patients.

Comparative study to see if treating with Osurdex in addition to Avastin in patients with retinal vein occlusions helps increased visual acuity outcomes

Transcorneal stimulation may enable neurons to survive degeneration processes via enhanced secretion of neurotrophic substances and direct stimulation of neurons.

The aim of this study is to compare formulated Posterior Subtenon Triamcinolone acetonide (PSTA) injection versus Posterior Subtenon Triamcinolone acetonide alone in the management of macular edema secondary to non-ischemic retinal vein occlusions, either central or branch.

Comparing ranibizumab and aflibercept in a treat and extend algorithm evaluating the number of needed injections over a 18 month period in patients with newly diagnosed CRVO.

We are comparing the patient experience between the standard 30 g needle to the smaller 33 g needle for intravitreal injections of ranabizumab or aflibercept for age related macular degeneration, diabetic macular edema, or retina vein occlusions.

In a recent study we could show that the early retinal venous vasoconstriction after grid photocoagulation in branch retinal vein occlusion (BRVO) is closely correlated to the visual outcome after three months. This could be of clinical importance, because the degree of vasoconstriction might be an early marker of treatment success, compatible with the idea that hypoxia is the major trigger of VEGF in BRVO. The present study evaluates the response of retinal vessel diameters to anti VEGF treatment with lucentis in patients with BRVO. This is done in an effort to gain insight into the retinal hemodynamic consequences of anti VEGF treatment in BRVO. The hypothesis that anti VEGF treatment is associated with a vasoconstrictor response in retinal vessel in patients with BRVO is tested.

A prospective interventional case series study was conducted on 20 eyes of 20 patients with active myopic choroidal neovascularisation (CNV) ,20 eyes with resistant diabetic macular edema and 15 eyes with non ischaemic central retinal vein occlusion(CRVO) after approval of the Ethical Committee of the Faculty of Medicine, Tanta University . All procedures were carried out under the tenets of the Helsinki Declaration. Written consent was provided by all participants after discussing the procedure, alternative treatment plans, follow-up schedules, and possible benefits and risks.

Randomized, double-masked trial designed to investigate the use of TLC399 (ProDex) in subjects with macular edema due to CRVO or BRVO.
