Filter by:The purpose of this study is to assess the efficacy of pegaptanib (Macugen®) for neovascular (exudative) age-related macular degeneration (AMD) when the first dose is administered to the submacular space instead of vitreous body in cases when previous state-of-the-art treatment for the AMD was deemed ineffective.
To define what procedures were used for the diagnosis and monitoring of the treatment age-related macular degeneration (AMD). What is the effect of the Macugen, compliance with Macugen treatment, safety profile of Macugen, final physician assessment of treatment with Macugen.
The objectives of this study are to evaluate the safety, tolerability, and pharmacokinetic profile of volociximab intravitreous injection in subjects with subfoveal choroidal neovascularization secondary to age-related macular degeneration (AMD).
Aims of the trial: Establishing the profile of the growth factors and other mediators of angiogenesis in different ocular fluids (aqueous humour, vitreous gel and ocular liquid in vitrectomized eyes), in the 2 most frequent proliferative retinopathies - diabetic proliferative retinopathy (PDR) and exudative age related macular degeneration (AMD). Following up the dynamic of this profile before and after intravitreal administration of Bevacizumab (Avastin) as an anti-VEGF blocker. Materials: The research will be conducted on the following categories of patients groups: - nondiabetic patients without AMD or any other diagnosed proliferative ocular disease (controls) - patients with age related macular degeneration (AMD groups) before and after intravitreal injections with Avastin - diabetic patients with different types of diabetic retinopathy, before and after intravitreal Avastin (diabetic groups) Methods: Samples from different ocular fluids will be collected from each group of patients. 10 growth factors and other 10 cytokines will be determined in the ocular fluids samples. Results: The results from the biochemical measurements will be statistically interpreted in order to obtain conclusions for the clinical practice. Conclusions: The conclusions of this trial will be used exclusively for research publications and communications, as well as for clinical practice.
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.
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.
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.
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.
1. Intravitreal injection can induce perioperative stress for the patients. 2. Different factors can modulate the pre-operative fear and physiologic reaction.
