Filter by:This study will compare the safety and efficacy of Medidur FA treatment in one eye to the sham-treated fellow eye of subjects with geographic atrophy secondary to AMD.
Evaluation of efficacy of alprostadil (prostaglandin E1) for treatment of patients suffering from dry age-related macula degeneration
The objective of the 18-month trial is to evaluate the natural history of geographic atrophy by assessing the rate of progression of the geographic atrophic lesion over time.
Wet age-related macular degeneration (AMD) is caused by the formation and growth of abnormal blood vessels (angiogenesis) in the retina. The new blood vessels have fragile walls and can leak fluid into the retina. The build-up of fluid (edema) under the macula can distort vision or cause vision loss. TG100801 is a topical (eye drop) therapy that has been shown to inhibit ocular angiogenesis, vascular leak, and inflammation in laboratory studies. The primary purpose of this pilot study is to evaluate the ability of topical administration of TG100801 to reduce the amount of fluid in the retina in patients with AMD following 30 days of treatment. An additional objective is to evaluate the safety of TG100801 in patients with AMD.
The purpose of this study is to compare the safety and effectiveness of bevasiranib given either every 8 weeks or every 12 weeks after an initial pre-treatment with 3 injections of Lucentis® (ranibizumab injection) compared to Lucentis® given every 4 weeks to people with wet AMD. Patients will be assigned at random (like tossing a coin) to receive one of three treatments options for 104 weeks.
The study will evaluate whether taking a nutritional supplement designed to increase macular pigment in the eye can improve a person's ability to adjust to darkness. Patients will be assigned to take either a placebo or nutritional supplement for 8 months. Vision will be assessed at baseline, 4 months, and 8 months.
VERTACL will investigate whether a triple therapy, Avastin®, half fluence verteporfin photodynamic therapy (PDT), and triamcinolone acetonide-preservative free (TAC- PF), results in improved 12-month vision outcome compared to Avastin® alone in participants with neovascular AMD.
The "blue light hazard" has been reported to cause retinal damage (oxidative stress), particularly to the central fovea due to its energetic, shorter wavelength visible photons, which is why blue-light filtering intraocular lenses have been developed for cataract surgery. The hormone melatonin has been reported to possess an efficient antioxidant capacity. Light information from the eye reaches the suprachiasmatic nuclei and inhibits melatonin secretion. Since melatonin is suppressed by light, we have a day-night rhythmicity, with increased levels at night. Melatonin suppression is wavelength-dependent with a peak sensitivity in the 446-477 nm (blue light) portion of the visible spectrum. The crystalline lens blocks most UV between 300 and 400 nm. The density of the lens increases with aging causing an alteration in the spectral absorption. The greatest increase in absorption occurs at the short wavelength end of the spectrum (around 400-470 nm). Age-related pupillary miosis and crystalline lens yellowing limit the blue light reaching the retina. This reduces the older adults' effective retinal light exposure to one tenth that of younger people. It has been shown that insomnia and depression decrease after cataract surgery and patients returned to youthful levels of melatonin. Since melatonin acts as an antioxidant, and more blue light filtering intra ocular lenses are implanted and thought to reduce photochemical damage in the macula, it would be interesting to show the positive influence of those blue light filtering intraocular lenses on daytime levels of melatonin in age-related macular degeneration patients.
This study will evaluate the effect of combination therapy with verteporfin photodynamic therapy and ranibizumab on visual acuity compared to ranibizumab monotherapy and the durability of response observed in patients with choroidal neovascularization secondary to age-related macular degeneration
The PDT/Lucentis trial will be a Phase IV comparative trial comparing the use of combination therapy with ITV ranibizumab and verteporfin PDT to ITV ranibizumab alone in patients with exudative AMD.
