Filter by:Ranibizumab (Lucentis) is currently the best treatment for wet Age-Related Macular Degeneration (AMD). To work, the drug must be injected by means of an intravitreal injection (IVT) into the vitreous (jelly-like material) cavity in the back of the eye, repeatedly at intervals ranging from one to several months. Endophthalmitis is a rare but devastating infection of the eye that occurs in approximately 0.2% of patients after IVT injection. Many ophthalmologists ask patients to use antibiotic eye drops after IVT injection in the hope that this may reduce the risk of endophthalmitis. There is no proof that this happens and there is a possible risk that repeated exposure to the same antibiotic may cause antibiotic resistance organisms (bacteria) to develop over time. The investigators hypothesize that repeated exposure to antibiotic during the initial stages of treatment for AMD will result in a progressive shift in the conjunctival flora with an increasing number of antibiotic resistant organisms appearing over time. If this is demonstrated, changes to the prevailing treatment approach will be needed to reduce the long term risk of a patient developing antibiotic resistant endophthalmitis during treatment.
This study was conducted because the FDA requested clinical information on potential effects of intravitreal injections of Macugen (pegaptanib sodium injection) on the corneal endothelium from a 1-year (minimum) post-approval clinical study to support that there are no adverse effects on the corneal endothelium following intravitreal injections of Macugen.
The purpose of the study is assess safety, bioactivity, and maximal tolerated dose of repeated weekly intravenous infusion of combretastatin A-4 phosphate (CA4P) in patients with neovascular age-related macular degeneration
Ranibizumab has been proven to be effective in large multicentre studies. However, the injections have to be repeated monthly. A combined therapy with the established photodynamic therapy might even be more effective, less intravitreal injections might be necessary due to a synergistic effect. The study will be conducted to explore whether intravitreal ranibizumab in monotherapy or in combination with verteporfin photodynamic therapy under a new time regime is an effective, safe and convenient treatment for patients with subfoveal Choroidal Neovascularisation (CNV) secondary to Age-Related Macular Degeneration (AMD).
Background: - The Age-Related Eye Disease Study 2 (AREDS 2) is looking at different eye diseases. Study participants will provide blood and saliva samples. The samples will be stored for research on eye diseases. Objectives: - To collect blood and saliva samples for AREDS 2 research. Eligibility: - AREDS 2 research study participants. Design: - Participants will provide blood and saliva samples. - The samples will be submitted with personal and medical information. This information will be collected during the AREDS 2 procedures.
Using an adaptive optics imaging device, retinal structures are observed in healthy and diseased subjects.
50 Patients with recalcitrant exudative age-related macular degeneration with a history of retinal or subretinal fluid after multiple intravitreal injections with ranibizumab 0.5mg and subsequently treated with ranibizumab 2.0mg, who are incomplete responders to 2.0mg of ranibizumab.
This study is to investigate the protective effects of supplemental lutein and zeaxanthin on early age-related macular degeneration (AMD) patients in China.
This study was conducted in two parts; Part A and Part B: Part B was initially planned to include two cohorts. Cohort 2 was cancelled following an interim analysis for efficacy in Part A of the study, and not due to any safety issues or concerns. Cohort 2 is not referred to again and part B cohort 1 is referred to as part B alone in the remainder of the document and is the subject of this report. Part B was conducted to assess the safety and tolerability of a single intravitreal (IVT) LFG316 10 mg/100 µL injection. There was no efficacy evaluation in Part B. The study employed a multicenter, randomized, sham - controlled, single masked design. Eight patients with advanced AMD were planned to be randomized in a 3:1 ratio to receive a single IVT dose of LFG316 (10 mg/100 µL) or sham injection. Patients assigned to a sham injection were treated the same as those assigned to LFG316, except that the hub of an empty syringe (without needle) was placed against the eye instead of the IVT injection.
This study is to determine the impact of the consumption of eggs rich in lutein/zeaxanthin from lucerne protein concentrate and DHA from microalgae on the plasma levels of these compounds but also on the macular pigment optical density, whose elevation may be beneficial in the prevention of Age-related Macular Degeneration (AMD).
