Filter by:Background: To identify characteristic morphological changes of the retina, their change over time and the association with visual function after combined photodynamic therapy (PDT) and intravitreal triamcinolone (IVTA). Methods: In this retrospective study, 40 patients (40 eyes) were treated with PDT and same day IVTA. Optical coherence tomography (OCT), fluorescein angiography (FA) and evaluation of distance visual acuity (VA) were performed. Main outcome measures were the anatomical changes within intra- and subretinal compartments and their detailed analysis and grading.
This is a one-year, randomized, single-center open-label pilot study of the safety and efficacy of combination ranibizumab and PDT for AMD. Eligible subjects will be randomized to either combination treatment, or ranibizumab monotherapy (control group). The combination treatment group will receive ranibizumab, followed 1 week later by verteporfin PDT. Additional treatments will be based on evidence of active disease (subretinal fluid on OCT or leakage on FA): repeat ranibizumab injections will be allowed monthly, and repeat PDT will be allowed every 3 months. The control group will receive "standard-of-care" ranibizumab monotherapy according to the protocol currently followed by most retinal specialists. Ranibizumab injections will be given at baseline and months one and two. Additional injections will be given at each monthly visit at which there is evidence of active disease by visual acuity, OCT and FA criteria.
The objective of this clinical study is to evaluate the safety and feasibility of focal delivery of radiation for the treatment of subfoveal choroidal neovascularization (CNV) in patients with age related macular degeneration that have failed Primary Anti-VEGF therapy.
Objective: The objective of this study was to determine whether the antioxidant supplements used in AREDS shifted the plasma pool of the AREDS subjects to a more reduced state. The AREDS subjects were randomly assigned to one of four treatment groups: 1. antioxidants (500mg Vitamin C, 4000IU Vitamin E, 15mg beta carotene) 2. zinc (80mg zinc oxide, 2mg cupric oxide) 3. antioxidants plus zinc; 4. placebo. None of the subjects received supplemental GSH or cyst (e) ine. Age-related macular degeneration (AMD) is the leading cause of severe visual impairment in elderly Americans, with an estimated 15 million people having some form of this disease. AMD primarily affects the central vision and many patients develop severe visual handicaps. Currently there are no clear established understandings of the etiology or pathogenesis of this disease.
This is a two-period study to evaluate the effect of repeat oral dosing of ketoconazole on the pharmacokinetics of single dose pazopanib administered as an eye drop
Stage 1 is a patient-masked, dose-escalation, safety evaluation of brimonidine intravitreal implant. Patients will receive implant in one eye and "sham" treatment (meaning no treatment) in the fellow eye. Stage 2 will begin after 1 month of safety has been evaluated for Stage 1. Stage 2 is a randomized, double-masked, dose-response, sham-controlled evaluation of the safety and efficacy of brimonidine intravitreal implant in patients with geographic atrophy from age-related macular degeneration. Patients will be followed for up to 2 years.
This study will use an eye imaging test called high speed indocyanine green angiography (HS-ICG), which examines leaky vessels in the eye, to try to find out why individuals respond differently to ranibizumab (Lucentis) treatment for wet age-related macular degeneration (AMD). The drug was recently approved by the Food and Drug Administration to treat this disease, but the response to the treatment varies markedly among individuals. People 50 years of age and older with wet AMD and vision that meets the research protocol criteria may be eligible for this study. Participants undergo the following procedures: Ranibizumab injections in the study eye once a month for 4 months. Additional injections are given only if the study eye shows signs of bleeding or leaking fluid. The eye is numbed before the injection and the eye area is cleaned with an antiseptic. Antibiotic drops are used for 3 days following the injection to prevent infection. Clinic visits once a month for 2 years for evaluations to monitor the response to treatment. The evaluations may include the following examinations and tests: - Eye examination with dilation, optical coherence tomography and photography: The examination measures visual acuity, thickness of your retina (the back of the eye) andeye pressure. Bright lights will also be used so that the doctor can see the back of your eye. Photographs of the eye may be taken. - Fluorescein angiography to examine the blood vessels in the eye: A dye called fluorescein is injected into a vein in the arm. The dye travels through the veins to the blood vessels in the eyes. A camera takes pictures of the dye as it flows through the blood vessels. This test is done eight times during the study. - Indocyanine green angiography to examine the blood vessels in the eye: The procedure is the same as for fluorescein angiography, but it uses a dye called indocyanine green. This test is done once a month for the first year of the study and then every 3 months.
This study will identify genes that are associated with inflammation or degeneration of the retina (membrane lining the back of the eye that relays vision signals to the brain). It is thought that many retinal conditions are due to an altered immune system and are based on how the person s genes function and communicate. People 4 years of age or older who have a retinal condition such as uveitis, age-related macular degeneration or diabetic retinopathy may be eligible for this study. Healthy volunteers and healthy people who have a family member with one of these conditions are also eligible. Patients with inherited retinal degeneration are excluded. Participants undergo the following tests and procedures: - Eye examination to assess visual acuity (eye chart test) and eye pressure, and to examine the pupils, lenses, retina and eye movements. Photographs of the inside of the eye may also be taken. The pupils are dilated with drops for this examination. - Blood draw for genetic testing. Participants may also undergo one or more of the following tests: - Optical coherence tomography. This is a type of photograph of the back of the eye to measure thickness of the retina. - Fluorescein angiography and indocyanine green angiography. Pictures of the eye s blood vessels are taken using either a fluorescein or indocyanine green dye. The dye is injected into a vein in an arm and travels to the blood vessels in the eyes. A camera takes pictures of the dye as it flows through the blood vessels. - Electroretinogram (ERG) to measure retinal function. The patient sits in a dark room for 30 minutes with his or her eyes patched. Then, a small metal disk electrode is taped to the forehead, the eye patches are removed, the surface of the eye is numbed with eye drops, and contact lenses are placed on the eyes. The patient then watches flashing lights. The contact lenses sense small electrical signals generated by the retina when the light flashes....
This study is a phase III, double-masked, randomized, study of the efficacy and safety of VEGF Trap-Eye in patients with neovascular age-related macular degeneration. Approximately 1200 patients will be randomized in Europe, Asia, Japan, Australia and South America.
This is a 28 day study to evaluate the pharmacodynamic effect of pazopanib eye drops on the central retinal thickness of AMD patients
