Filter by:To demonstrate the ability of intermediate AMD subjects to follow the instructions for use and properly operate on their own the Preview PHP in home use environment, after going through training session.
The study will evaluate the safety and efficacy of the intravitreal dexamethasone implant as adjunctive therapy to Anti-VEGF treatment in the study eye of treatment naïve subjects with choroidal neovascularization secondary to age-related macular degeneration. Subjects will be followed for 26 weeks.
This study is designed to compare four currently used types of anesthesia used prior to intravitreal injection in order to evaluate the most effective method of anesthesia in reducing pain and discomfort associated with intravitreal injections.
This randomized, controlled clinical trial, the Low Vision Depression Prevention TriAL (VITAL), will test the efficacy of collaborative low vision rehabilitation (LVR) to prevent depressive disorders in Age-Related Macular Degeneration (AMD). In this innovative intervention, a low vision occupational therapist collaborates with a low vision optometrist to develop and implement a care plan based on a subject's vision status, rehabilitation potential, and personal rehabilitation goals. An independent rater masked to treatment assignment will assess depressive disorders meeting DSM-IV criteria (primary outcome) and targeted vision function and vision-related quality of life (secondary outcomes) at baseline and then at 4 months to evaluate short-term effects (main trial end point) and at 12 months to evaluate long-term effects.
Age-related macular degeneration (AMD) is a disease that, in time, destroys the macula, which is the central part of the retina that gives sharp central vision. The primary purpose of this study is to assess the safety of iSONEP which is a humanized monoclonal antibody against a bioactive lipid, sphingosine 1-phosphate (S1P).
This study will determine if 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 needed for sharp, clear vision. There are two types of AMD, wet and dry. In dry AMD, cells in the macula die.GA may at least partly be caused by inflammation. Sirolimus helps prevent inflammation and therefore may help treat GA. People with GA in both eyes with visual acuity between 20/20 and 20/400 in each eye may be eligible for this study. Participants undergo the following tests and procedures: - Sirolimus injections in the study eye at each 3-month clinic visit. The drug is injected under the outer layer of the eye after the patient receives antiseptic and numbing drops. Antibiotic drops are continued for 2 days after the injection. - Eye examinations before the first injection, 1 month after the first injection, during each clinic visit (11 to 15 visits over 2 to 3 years) and 3 months after the final injection. The examination includes testing visual acuity, measuring eye pressure and checking eye movements. To examine the inside of the eye, the pupil is dilated with eye drops. Regular photographs of the inside of the eye and optical coherence tomography photographs, which allow measurement of the thickness of the retina, may be taken during the eye examination. - Autofluorescence imaging. The patient sits in a chair with his or her head placed in a chin rest in front of a camera. A light in the camera is used to scan the eye. - Blood tests. Blood is drawn at the first visit and at up to seven study visits to check blood chemistries, such as liver and kidney function. - Urine pregnancy test for women who are able to become pregnant.
The purpose of this study is to determine the safety and efficacy of an ocular sirolimus (rapamycin) formulation in combination with Lucentis in patients with sub-foveal choroidal neovascularization secondary to age-related macular degeneration.
Visual outcomes using monthly ranibizumab therapy are well established in clinical trials, but the best way to assess when and how to treat patients with PRN therapy has not been proven. Information is lacking on Multi-focal ERG and microperimetry outcomes with ranibizumab therapy. Additionally, VA and OCT outcomes don't always correlate and other assessments such as the Multi-focal ERG and microperimetry may be useful as early predictors of when patients should be retreated. This study will assess 2 groups (monthly and PRN therapy) and assess high resolution OCT, microperimetry, and Multi-focal ERG outcomes. For the PRN group retreatment will be based on OCT criteria. We will investigate if microperimetry or multifocal ERG would have been an early predictor of fluid recurrence.
Purpose is to evaluate Rheopheresis for the treatment of patients with high-risk dry age-related macular degeneration and no therapeutic alternative. Rheopheresis is a method of therapeutic apheresis using the methodology of double filtration plasmapheresis to treat microcirculatory disorders.
The study purpose is to demonstrate that the target population can receive a packed FORESEE HOME unpack it, install and operate it to an extent that the FORESEE HOME can monitor them for changes in the visual field with good specificity. And evaluate the device usage on a small scale, at the subjects' homes before a commercial use.
