Filter by:Age-related macular degeneration (AMD) is a disease that, in time, destroys the macula, which is the central part of the retina that gives sharp central vision. The primary purpose of this study is to assess the safety of iSONEP which is a humanized monoclonal antibody against a bioactive lipid, sphingosine 1-phosphate (S1P).
Visual outcomes using monthly ranibizumab therapy are well established in clinical trials, but the best way to assess when and how to treat patients with PRN therapy has not been proven. Information is lacking on Multi-focal ERG and microperimetry outcomes with ranibizumab therapy. Additionally, VA and OCT outcomes don't always correlate and other assessments such as the Multi-focal ERG and microperimetry may be useful as early predictors of when patients should be retreated. This study will assess 2 groups (monthly and PRN therapy) and assess high resolution OCT, microperimetry, and Multi-focal ERG outcomes. For the PRN group retreatment will be based on OCT criteria. We will investigate if microperimetry or multifocal ERG would have been an early predictor of fluid recurrence.
This is s randomized, multi-center, double blind, 3 arm, phase I/II pilot study to evaluate the safety and efficacy of treatment with ORA102 combined with Avastin (Bevacizumab) versus Avastin alone, in patients with neo-vascular age related macular degeneration (AMD).
The objective of this study is to evaluate the effects of 2 intravitreal injections with Ranibizumab or Avastin on endothelial function in subjects with neovascular macular degeneration compared to patients with dry AMD.
This phase II study was designed to evaluate the safety, tolerability, and efficacy of bevacizumab treatment in conjunction with PDT at the low fluence rate compared with bevacizumab alone or combined with PDT at the standard fluence rate, in patients with all types of choroidal neovascularization secondary to AMD. Hypothesis: bevacizumab in combination with PDT (low and standard fluence rate) will i) delay time to retreatment, ii) reduce the average number of treatments required compared to bevacizumab alone and iii) at low PDT fluence rate will improve long-term safety profile.
Background: To identify characteristic morphological changes of the retina, their change over time and the association with visual function after combined photodynamic therapy (PDT) and intravitreal triamcinolone (IVTA). Methods: In this retrospective study, 40 patients (40 eyes) were treated with PDT and same day IVTA. Optical coherence tomography (OCT), fluorescein angiography (FA) and evaluation of distance visual acuity (VA) were performed. Main outcome measures were the anatomical changes within intra- and subretinal compartments and their detailed analysis and grading.
One concern about repeated intravitreal injections of bevacizumab (Avastin) and ranibizumab (Lucentis) in wet age related macular degeneration, is that in addition to blocking the proteins that triggers the development and proliferation of abnormal vessels in the center of the retina, they may also result in changes in the normal vessels that feeds the outer part of the retina. Small vessels with fenestrations (such as those that feed the outer part of the retina, which are called choriocapillaris) appear to be especially sensitive to this protein (called vascular endothelial growth factor, VEGF) withdrawal. It is estimated that global blood flow in the vascular layer under the retina (called choroid) may be indirectly assessed by measuring the amplitude of the ocular pulsation (the pressure inside the eye change according to the cardiac cycle, similar to the change in blood pressure) which is called Ocular Pulse Amplitude (OPA). The Pascal Dynamic Contour Tonometer (Pascal DCT) is a new tonometer (a device which measures the pressure within the eye) designed to measure intraocular pressure and ocular pulse amplitude. No published study has yet assessed the effect of bevacizumab (Avastin) or ranibizumab (Lucentis) treatment for wet AMD (or on any other retinal disease) on OPA. This is our aim in this pilot study, in which we will measure the pressure within the eye just prior to bevacizumab/Ranibizumab treatment, followed by repeated measurements a week and a month after the treatment. For this purpose, up to 60 patients with wet AMD will be recruited.
This study is a phase III, double-masked, randomized, study of the efficacy and safety of VEGF Trap-Eye in patients with neovascular age-related macular degeneration. Approximately 1200 patients will be randomized in Europe, Asia, Japan, Australia and South America.
Neovascular age-related macular degeneration (AMD) is the leading cause of severe vision loss in the Western world. Intravitreal ranibizumab has recently become the treatment of choice for neovascular (AMD). Limitations to ranibizumab however include the high cost for the drug and the need for frequent intravitreal re-injections. The investigators' hypothesis is that when ranibizumab is combined with transpupillary thermotherapy (TTT) the number of necessary retreatments with Lucentis will be significantly reduced as compared to ranibizumab alone.
Patients with neovascular Age-related macular degeneration (AMD) and the particular feature of pigment epithelial detachments (PEDs) were not studied in the Phase III trials for ranibizumab (Lucentis). The PrONTO study was the first ranibizumab study to enroll such patients but only treated with ranibizumab until fluid within the layers of the retina was absent, not until the entire PED was absent. This study hypothesizes that there may be a difference in benefit between patients treated until just the retinal edema is gone and those in which the retinal edema and PED are both gone.
