Filter by:To determine if Visudyne photodynamic therapy (low or very low fluence rate) combined with intravitreal injections of bevacizumab (Avastin) compared with bevacizumab alone will, with similar safety and efficacy, delay time to retreatment with bevacizumab after the initial treatment, in subjects with new wet AMD Hypothesis: PDT in combination with Avastin at either the low or very low fluence rate will delay time to retreatment and reduce the average number of treatments required, compared to Avastin alone, but will have a similar safety and efficacy profile.
The primary objective of this study is to assess the ability of the PHP & HPHP to detect newly diagnosed non treated Chorodial neovascularization (CNV) lesion associate with advanced age related Macular Degeneration (AMD) and differentiate them from Early/intermediate/GA AMD
The primary objective of this study is to assess the ability of the PreView PHP(study device)to detect newly diagnosed non-treated Choroidal Neovascularization (CNV)lesion associate with advanced Age-related Macular Degeneration (AMD) or Myopia and differentiate them from Intermediate AMD or Geographic Atrophy (GA)or patients with high Myopia with no CNV. This study secondary is to enhance NotalVision normative database.
This study will examine skin and blood cells for genetic changes related to the development of age-related macular degeneration, an eye disease that can significantly impair the ability to read, drive, and carry out daily activities. It is the most common cause of vision loss in people over the age of 50. People with age-related macular degeneration and healthy normal volunteers age 50 years or older may be eligible for this study. Candidates will undergo a medical history, physical examination and eye examination with dilation of the pupils. Photographs of the eye will be taken with a special camera. Study participants will have blood drawn three times (no more than 6 tablespoons each time) and will undergo three skin biopsies. For the skin biopsy, an anesthetic is injected under the skin and a small piece of skin-approximately 1/4-inch cube-is removed. The blood draws and biopsies will be done at 7- to 10-day intervals. In most cases, a single biopsy is done at each visit, but it may be necessary to take-at most-one additional biopsy from the other arm during the same visit. Patients will return for one follow-up visit 7 to 10 days after the last biopsy for examination of the biopsy site and removal of any stitches. The results of this study may provide investigators information needed to develop new means of diagnosing and treating age-related macular degeneration.
To study the effect of mild laser treatment on the incidence of exudative complications in soft drusen maculopathy. We hypothesise that mild laser treatment causing a proliferation of the retinal pigment epithelium and enhancing the capacity of clearing drusen material from Bruch's membrane.
The purpose of the study is to determine the concentration of anecortave acetate (15 or 30 mg versus placebo) that is safe and effective for the inhibition of the growth of blood vessels in the retina in patients with wet AMD.
The purpose of this study is to investigate whether taking 4-methylpyrazole (4-MP, fomepizole, Antizol™) inhibits dark adaptation of the eye. In other words, we are testing if 4-MP slows the processing of vitamin A derivatives in the eye. By slowing down these processes, individuals with Stargardt disease may have better chances of saving their remaining vision. 4-MP has been shown to slow dark adaptation in animals, and is FDA approved for human use to treat individuals with methanol or ethylene glycol (antifreeze) poisoning by shutting down the body's ability to process alcohols. This medication has an excellent safety profile and has been reported to have no short-term or long-term side effects, as long as patients refrain from any alcohol while the medication is in the body. A single dose of 4-MP remains in the body for about 12 hours, and therefore, it may inhibit dark adaptation of your eyes for up to 12 hours. Studying the effects of 4-MP may lead to effective medical treatment to save Stargardt patients' vision, and may also have similar effects in other macular degenerative diseases.
The long-term goal is to show that retinal transplantation can help to prevent blindness and to restore eyesight in patients with dry age related macular degeneration.
Oral supplementation with the Age-Related Eye Disease Study (AREDS) formulation (antioxidant vitamins C and E, beta carotene, and zinc) has been shown to reduce the risk of progression to advanced age-related macular degeneration (AMD). Observational data suggest that increased dietary intake of lutein + zeaxanthin (carotenoids), omega-3 long-chain polyunsaturated fatty acids (docosahexaenoic acid [DHA] + eicosapentaenoic acid [EPA]), or both might further reduce this risk. AREDS2 was designed to test whether adding lutein + zeaxanthin, DHA + EPA, or lutein + zeaxanthin and DHA + EPA to the AREDS formulation might further reduce the risk of progression to advanced AMD. A secondary goal was to test the effects of eliminating beta carotene and reducing zinc dose in the AREDS formulation.
The PrONTO Study was designed to evaluate the response of neovascular age-related macular degeneration (AMD) patients to intravitreal Lucentis using Optical Coherence Tomography (OCT) imaging. OCT was then used to determine the need for retreatment after 3 monthly injections of Lucentis. Patients would be followed for 2 years.
