Filter by:Background: - Wet age-related macular degeneration (AMD) occurs when abnormal blood vessels grow in the back of the eye, and leak blood and other fluids that damage the eye, produce scarring, and lead to blindness. People diagnosed with wet AMD have increased production of a body chemical called vascular endothelial growth factor (VEGF). VEGF is important in the formation of blood vessels in the body, and decreasing the production of VEGF is believed to help wet AMD patients by preventing or slowing the growth of the abnormal blood vessels. Anti-VEGF drugs have been used to decrease the production of VEGF, but some people do not respond completely to these drugs. - A protein in the body called mTOR also plays a critical role in regulating how cells divide and grow and obtain their blood supply. The experimental chemical Palomid 529 inhibits the production of mTOR. Researchers are interested in determining whether Palomid 529 is safe and can help individuals with wet AMD who have not completely responded to anti-VEGF treatments. Objectives: - To evaluate the safety and effectiveness of Palomid 529 as a treatment for wet age-related macular degeneration in individuals who have not responded to standard anti-VEGF treatments. Eligibility: - Individuals with wet age-related macular degeneration in at least one eye that has not responded to standard anti-VEGF treatments. Design: - Prior to the first visit, participants should have been seen at the National Eye Institute clinic under a screening or teaching protocol, or NIH protocol 08-EI-0103, High Speed Indocyanine Green Angiography Findings in Induction Regimen of Intravitreal Ranibizumab Injection for Neovascular Age Related Macular Degeneration. One eye will be designated as the study eye to receive the Palomid 529 treatment. - Participants will have a full physical examination and medical history, a full eye examination to evaluate eye health and vision, angiography to examine the blood vessels in the eyes, and blood and urine tests during the study - Participants will receive an injection of Palomid 529 into the study eye every 4 weeks during the study, for a total of three injections. Participants may also receive anti-VEGF injections such as ranibizumab (Lucentis ) or bevacizumab (Avastin ) in the study eye 12 days before and 12 days after the Palomid 529 injection. - Participants may have standard-of-care treatments for the non-study eye if it has wet AMD as well, but may not receive experimental treatments in the non-study eye while they are in this study. - Participants will return for long-term follow-up examinations as directed by the study researchers.
In the Western World, Age Related Macular Degeneration (ARMD) is a leading cause of blindness. This disease was once thought to be a natural part of aging, but recent research has introduced effective treatments. ARMD is related to the body initiating an immune response in the eye, as if responding to an infection. Vision is impacted as ocular tissue becomes inflamed and new blood vessels form at the back of the eye, a process called angiogenesis. In the more severe wet form of ARMD, blood and fluid leak out of the vessels and impair the eye's structure and function. Many studies have shown that ranibizumab, a drug that stops the formation of new blood vessels (an anti-angiogenic agent) can delay damage to the eye and often restore vision. The investigators believe the best drug therapy will also stop the inflammation. Triamcinolone acetonide, a steroid drug, has shown the potential to effectively reduce inflammation in this application. The investigators aim to investigate if patients receiving a combination treatment of ranibizumab and triamcinolone acetonide improve their visual abilities more than those receiving just ranibizumab treatment alone. Secondarily, the investigators will also investigate how often patients receiving each drug therapy regime require re-treatment and how often they experience further vision loss.
Long-term observational study to assess the safety, efficacy and quality of life of patients with neovascular age-related macular degeneration (AMD) under Macugen treatment.

This study is designed to assess the efficacy and safety of multiple intravitreal injection of KH902 in patients with CNV due to AMD.
The purpose of this study is to test the hypothesis that proton beam irradiation combined with intravitreal anti-VEGF therapy is safe and potentially more effective than intravitreal anti-VEGF therapy alone in eyes with exudative age-related macular degeneration.
In this fifth year of anti-VEGF therapy for neovascular AMD, retinal physicians are collecting groups of patients who either do not or only partially respond to anti-VEGF therapy. This study will evaluate the efficacy and safety of 2mg ranibizumab specifically for patients with fibrovascular PEDs that have not resolved following at least 6 consecutive injections of ranibizumab or bevacizumab over the previous 12 months. The investigators hypothesize that the 2mg dose will be able to completely eliminate the persistent PEDS in these patients.
The purpose of this study is to determine a possible implication of CD21, CD35 and CD55 in the pathogenesis of age-related macular degeneration. The aim is to asses a difference in expression rates of these factors on AMD-patients and a healthy control group.
This study is designed to access the safety and efficacy of multiple injections of KH902 at variable dosing regimens in patients with CNV due to neovascular AMD.
The primary purpose of this study was to demonstrate a biological effect of AL-78898A, as measured by change (reduction) in central subfield (CSF) retinal thickness 4 weeks after a single intravitreal injection, as compared to LUCENTIS.
