Active clinical trials for "Macular Degeneration"

This is a pilot study to evaluate the safety of the Model WA-NG telescope prosthesis in patients with bilateral moderate to profound central vision impairment due to end-stage age-related macular degeneration.

INTRODUCTION: Acting directly on the anti-radical enzyme chain, the superoxide dismutase (SOD), a major enzyme of the anti-oxidant system, provides an alternative of the antioxidants treatment in ARMD. Its synthesis depends on the cellular oxygenated reactive species, and leads to the conversion of the superoxide ion (O2-) into hydrogen peroxide (H2O2). This compound is the cell watch guard continuously regulating a free radicals' detoxifying chain. Subsequently, by increasing the production of H2O2, the administration of SOD can trigger endogenous/internal antioxidant mechanisms. Oral administration of SOD is possible in its galenic form, Glisodine. The purpose of this study was to evaluate the protective effect of SOD on the bilateralization of the disease.

Visual outcomes of the eye with large subretinal hemorrhages (bleeding under the retina) due to Age-Related Macular Degeneration (AMD) are poor. The Submacular Surgery Trial (SST) showed that no statistically significant improvement in vision resulted from surgical removal of the layer of abnormal blood vessels causing the bleeding. However, placement of a gas bubble into the gel of the eye along with removal of the blood has shown some success. However, this does not treat the underlying condition of the AMD. Intravitreal injections (into the gel of the eye) of a drug called Lucentis has been shown to be highly effective in the treatment of AMD, yet its penetration through areas of thick blood caused by subretinal hemorrhage is not known. This study is proposing to treat the AMD causing the subretinal hemorrhage with a vitrectomy (surgery involving removing the gel inside the eye, and membrane layers of the eye) followed by Lucentis placed between the layers of the retina and then with or without a gas bubble. In order to determine if the the subretinal Lucentis alone is beneficial, 5 of the 10 patients enrolled will get a gas bubble and the other 5 will not.

The objective of this study is to confirm the safety and to establish the effectiveness of low voltage external beam radiosurgery using the IRay System for the treatment of subjects with recurrent leakage secondary to neovascular Age-related Macular Degeneration (AMD) as determined by decreasing the number of Lucentis injections required during the first 12 months of the study.

Patients with advanced dry AMD with GA meeting inclusion criteria will be randomized in one eye in a 1:1:1 ratio comparing intravitreal high or low dose AAVCAGsCD59 with a sham injection. All enrolled subjects will be followed for 24 months to evaluate reduction in GA growth and safety of intravitreal AAVCAGsCD59.

The purpose of this study is to assess the Safety and Efficacy of IONIS-FB-Lrx for up to 120 patients with Geographic Atrophy secondary to Age Related Macular Degeneration

The purpose of the study is to evaluate the efficacy and safety of CNTO 2476 cells administered into the subretinal space by the suprachoroidal surgical approach and the subretinal access kit (SRAK-02) in participants with visual acuity impairment associated with Geographic Atrophy (GA) secondary to Age Related Macular Degeneration (AMD).

This study evaluates the treatment of Dry Macular Degeneration and the resulting change in vision with a very, very low current that is similar to what occurs in the body naturally. In Phase 1, 16 participants will be treated, with half receiving treatment and half a sham (no treatment). After the treatment period of one week, those not treated will be treated. In Phase 2, all participants will be treated.

The purpose of this study is to determine whether 2RT nanosecond laser therapy slows the progression to advanced age-related macular degeneration.

This study is to investigate the protective effects of supplemental lutein and zeaxanthin on early age-related macular degeneration (AMD) patients in China.
