Filter by:Background and Objective: To evaluate the efficacy of cooled versus room temperature artificial tears in reducing post intravitreal injection (IVI) ocular discomfort. Patients and Methods: Patients receiving IVI were randomized to either cooled or room temperature tears intervention groups. Both groups rated their ocular discomfort following IVI before intervention and again after administration of cooled or room temperature tears.
To compare the effect of intravitreal-Bevacizumab and Triamcinolone with intravitreal-Bevacizumab alone on visual acuity and central foveal thickness in patients with macular edema secondary to central retinal vein occlusion.
This is a Phase III, multicenter, randomized, double-masked, active comparator-controlled, parallel-group study evaluating the efficacy, safety, and pharmacokinetics of faricimab administered by intravitreal (IVT) injection at 4-week intervals until Week 24, followed by a double-masked period of study without active control to evaluate faricimab administered according to a personalized treatment interval (PTI) dosing regimen in patients with macular edema due to central retinal vein occlusion (CRVO) or hemiretinal vein occlusion (HRVO).
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.
This study evaluates whether intravitreal autologous CD34+ stem cell therapy is safe, feasible and potentially beneficial in eyes with vision loss from central retinal vein occlusion (CRVO). Half of the participants will receive immediate cellular therapy followed by sham therapy 6 months later, while the other half will receive immediate sham therapy followed by cellular therapy 6 months later. Participants will be followed for a total of 1 year.
This study evaluates the efficacy and safety of Conbercept ophthalmic injection. This is a multi-center, randomized, double-masked, placebo-controlled phase III clinical study. 237 patients with central retinal vein occlusion(CRVO) are expected to be enrolled in the study and randomly assigned into the Conbercept ophthalmic injection treatment group or the control group at a ratio of 2:1.
Central retinal vein occlusion (CRVO) occurs when the main blood vessel that transports blood away from the retina (the very back portion of the eye) becomes blocked, causing the leakage of fluid into the retina and thereby causing a swelling of the macula (the portion of the retina responsible for fine vision). This swelling is called macular edema. When the macula swells with fluid, central vision becomes blurry. The study drug aflibercept has been shown to reduce the amount of fluid and blood leaked into the retina. It can help to stabilize, and in many cases, improve the vision loss related to CRVO. Aflibercept has been approved for the treatment of macular edema secondary to CRVO in the United States (US), European Union (EU), Japan, and other countries. The study was considered research because, although the study drug was already on the market for macular edema secondary to CRVO, there were no studies available that addressed the questions of what were useful intervals for treating and assessing patients, how did they differ among patients, and how were criteria applied for retreatment. The purpose of this study was to evaluate the effectiveness, treatment interval, and safety of the treatment regimen (pattern for administering treatment) in subjects with macular edema secondary to CRVO. In addition, this study explored new imaging methods for assessing the affected eye.
In central retinal vein occlusion (CRVO) a blood clot blocks the venous outflow of the entire retinal circulation. This leads to retinal and vitreous hemorrhages, retinal edema and neovascularization. The development of a microneedle and surgical stabilizer made it possible to perform a prolonged (10 minutes) retinal vein cannulation with infusion of Ocriplasmin. Ocriplasmin has the advantage over tissue Plasminogen Activator (tPA) that it already is an active enzyme and a strong fibrinolyticum. This study aims to investigate the feasibility and safety of local intravenous Ocriplasmin for CRVO.
The primary objective of this study is to measure physician knowledge and understanding of the key safety information contained in the Eylea vial preparation instruction card, the intravitreal injection procedure video, and the product monograph.
Diabetic macular edema (DME), wet-AMD and macular edema secondary to vein occlusions are the leading cause of blindness in developed countries. Several therapies have been studied as such laser treatment and intravitreal injections of corticosteroids or anti-VEGF drugs. In terms of public health the long term treatment with the current available drugs is very expensive and new therapies with the same or better effect should be investigated. This study intends to evaluate the efficacy and safety of intravitreal injections of ziv-aflibercept for the treatment of patients with DME, wet-AMD and macular edema secondary to vein occlusions.
