Active clinical trials for "Macular Degeneration"

Exudative age-related macular degeneration ("wet" AMD) continues to be a leading cause of central vision loss in the US for those over fifty years of age, despite the availability of several effective interventions to contain damaging neovascularization (new, abnormal blood vessel growth). The effectiveness of treatments is challenged by patients' lack of ability to recognize the need for urgent care between regular office visits. The Amsler and Yanuzzi tests, the only widely used self-tests for AMD, have proven largely ineffective at enabling patients to recognize the signs that they should consult their retina specialist for treatment. For optimal benefit, patients should be able to self-monitor their vision over time and detect changes that may be indicative of an exudative event. To facilitate compliance these observations should be part of a larger and more engaging program of AMD awareness and self-monitoring. Among the principal shortcomings of the current "gold-standard" Amsler grid are periodicity of the test pattern and lack of individual adjustment, and therefore the reliability and accuracy of this test are less than optimal for the detection of exudative retinal changes in AMD patients. In phase I of the current study, the investigatorsW developed and evaluated several versions of improved grids, both on paper and on the Internet. These patent-pending Visual and Memory Stimulating (VMS) grids proved at least equivalent to the Amsler grid in facilitating a substantial degree of recall of prior measurements, necessary for monitoring vision over time. Adjustment features were incorporated in the on-line version to allow patients to customize their grid to their particular visual field. In the phase II study the use of VMS grids will be supplemented by a test booklet that contains educational materials and diary based survey questions in addition to the printed VMS grids; the effectiveness of this booklet for self-monitoring will be compared the standard of care (Amsler grid). Goal of the study is to demonstrate that use of the test booklet leads to more rapid identification of newly developing vision problems, earlier diagnosis and treatment of incipient wet AMD that should result in fewer people losing their vision and less severe losses of vision.

The purpose of this study was to assess the safety, tolerability, and the effects of treatment on ocular outcomes following a single intravitreal administration of ESBA1008 compared with LUCENTIS® in patients with exudative age-related macular degeneration (AMD).

The purpose of this study is to evaluate the efficacy of vitrectomy, without gas tamponade or laser photocoagulation to the margin of the optic nerve, for the treatment of macular detachment associated with optic disc pits and to characterize retinal manifestations during treatment of optic pit maculopathy using optical coherence tomography (OCT). Vitrectomy with induction of a PVD at the optic disc without gas tamponade or laser photocoagulation appears to be an effective method of managing macular detachment due to optic disc pits. OCT scanning pre- and postoperatively suggests that peripapillary vitreous traction with the passage of fluid into the retina through the pit is the cause of the schisis-like separation seen in optic disc pit maculopathy.

The primary purpose of this study is to assess the safety & tolerability of an investigational drug 20089 TA (6.9 mg or 13.8 mg) when used adjunctively with Lucentis 0.5 mg in subjects with sub-foveal neovascular AMD.

A study to evaluate pazopanib tablets in male and female adults of non-child bearing potential with subfoveal CNV due to neovascular AMD. The goal is to assess safety and how well the subjects tolerate the drug. The study will also look at how the body breaks down and metabolizes the drug. All subjects will start the study up to 8 days prior to receiving drug. Once started subjects will take one tablet each day for 28 days. A follow up visit will occur approximately 2 weeks after drug is stopped.

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 study will involve approximately 40 subjects aged 55 or above who have exudative age-related macular degeneration (wet AMD). Patients will be randomized to receive one of two doses of rAAV.sFlt-1 or assigned to the control group.

The purpose of this study is: To evaluate the safety and tolerability of RPE cellular therapy in patients with SMD . To evaluate potential efficacy endpoints to be used in future studies RPE cellular therapy.

This study will determine whether a drug called sirolimus is safe to give to people with geographic atrophy (GA) and if it can help preserve vision in patients. GA is an advanced form of dry age-related macular degeneration (AMD). AMD affects the macula, the central part of the retina at the back of the eye needed for sharp, clear vision. There are two types of AMD, wet and dry. In dry AMD, cells in the macula die. GA may be partially caused by inflammation. Sirolimus helps prevent inflammation and therefore may help people with GA. Researchers want to see whether sirolimus can help prevent vision loss in people with GA. People at least 56 years of age who have GA related to AMD in both eyes may be eligible for this study. This study requires at least 8 visits to the National Eye Institute over 1 year. Study visits will be every 2 months for 1 year. Participants will undergo the following procedures: Participants will be screened with a medical history and physical exam. They will also have blood and urine tests, and eye exams. One eye will be selected as the study eye to receive the sirolimus injections. Participants will have a sirolimus injection into the study eye at the first visit and every 2 months thereafter unless contraindicated. There will be a follow-up eye exam 1 month after the first injection.

Phase 1: The purpose of this study is to evaluate the safety and tolerability of single ascending doses of hI-con1™ for subjects with Age-Related Macular Degeneration. Phase 2: The purpose of this study is to evaluate the safety of 3 injections of hI-con1™ at 2 different dose levels.
