Filter by:Background: Age-related macular degeneration (AMD) and cataracts are two eye diseases. They were studied in the Age-Related Eye Disease Study (AREDS2) and the AREDS2 Follow-On study. These studies followed the natural course of the diseases. They also provided data on the long-term effects of certain oral supplements on AMD. Objective: To study the long-term effects of oral supplements on several things. These include incidences of lung cancer, development of late AMD, cataract surgery, cognitive function, and cardiovascular events. Eligibility: Former AREDS2 and AREDS2 Follow-On participants Design: Participants will have 1 visit. It will include: An eye exam that tests how well participants can see, measures eye pressure, and checks eye movements. The pupil will be dilated with eye drops. Pictures will be taken of the retina and the inside of the eye. Participants will grip a device in their hand to measure their grip strength. A blood sample will be taken. This will be stored for future genetic research. Cells may be created from the sample. A small sample of skin will be taken. Sponsoring Institution: National Eye Institute
Purpose To report the long-term efficacy of patients with neovascular age-related macular degeneration (nAMD) treated with anti-vascular endothelial growth factor (VEGF) in Changhua Christian Hospital in Taiwan. Method Retrospective case series of patients with nAMD that were treated with intravitreal injection of anti-VEGF and had a minimum follow up of 48 months. Every patient was initially treated with 3 loading doses of either bevacizumab or ranibizumab, followed by a loose treat and extend regimen. Eyes were divided into 2 groups according to whether aflibercept was later used as a rescue therapy (group 2) or not (group 1). Patients underwent best-corrected visual acuity (BCVA) testing, optical coherence tomography, and ophthalmic examination at baseline and all the scheduled follow-up visits.
A new fundus-guided microperimeter (MP-3S) has been developed by Nidek, Inc. to track the fundus of the patient and present stimuli in specific anatomically-defined locations. Furthermore, this tracking means that exactly the same locations can be tested on subsequent (follow-up) visits. The investigators will use a method called two-color perimetry to map rod and cone sensitivity on this device. With this technique, the sensitivity difference (blue-red) to chromatic test stimuli can be used to determine whether rods, cones or both photoreceptor systems mediate the threshold at a given location in the macula.
Early Phase I Study of the Safety and Preliminary Efficacy of Human Fetal Retinal Pigment Epithelial(fRPE) Cells Subretinal Transplantation in Age-Related Macular Degeneration(AMD) Patients
This is an interventional, prospective, randomized, comparative monocentric study aiming to evaluate the safety and efficacy of Resveratrol to reduce the progression of exudative Age-Related Macular Degeneration.
The purpose of this study is to evaluate the safety and efficacy of X-82 in the treatment of vision loss due to wet AMD.
Background: - Alzheimer s disease affects the brain and causes memory and thinking problems in older people. Macular degeneration (MD) is an eye condition. It is the leading reason that people over age 55 in the United States lose their central vision. Central vision is important for seeing fine details and for tasks like reading and driving. A feature of Alzheimer s disease is plaques in the brain. A feature of age-related MD is deposits in the retina in the eye. Researchers want to learn more about these diseases and find out if they are related. Objective: - To see whether there is a relationship between Alzheimer s disease and age-related macular degeneration. Eligibility: - People with or without Alzheimer s disease enrolled in another study. Participants must have someone to help them take part in this study. Design: - Participants will be screened through the other study. They will have 1 visit. The tests will take about 3 hours. - Participants will answer questions about their medical and eye history. - Participants will have an eye exam to test how well they see. Their eye pressure will be measured and their eye movements will be checked. - Participants will get eye drops to dilate their pupils. Researchers will take pictures of the retina and the inside of the eye. Researchers may measure the thickness of the retina. - Participants will continue to receive care from their regular eye doctor during and after the study.
Background: - The Age-Related Eye Disease 2 Study (AREDS2) looked at two eye diseases. These were age-related macular degeneration (AMD) and cataracts. Participants in that study took supplement pills and some participants had additional pictures taken of their eyes. That study is now over. Researchers want to do a follow-up study after participants finish taking the pills, to see if they cause long-term effects on AMD. This study will be combined with follow-up visits of the AREDS2 study if possible. Objectives: - To learn more about the effect of oral supplements on AMD. Eligibility: - People who completed the AREDS2 study. Design: - Participants will have up to 2 study visits over 6 18 months. - Each visit will last up to 5 hours. The visits will be combined with annual follow-up visits in the AREDS2 study if possible. - At each visit, participants will undergo an eye exam and photography. - The eye exam includes testing sight, measuring eye pressure, and checking eye movements. To examine the inside of the eye, the pupil will be dilated with eye drops. - Photographs of the inside of the eye may be taken during the eye exam and while the eyes are dilated. - A contact lens may be placed on the eye briefly to look at the retina at the back of the eye.
Background: - Age-related macular degeneration (AMD) is a disease that blurs the sharp vision needed for activities such as reading, sewing, and driving. It affects the macula, the center of the retina at the back of the eye, which allows a person to see fine detail. Researchers want to collect medical histories, eye exam data, and genetic information that may be associated with AMD. They want to compare this information with information collected from people without AMD. Objectives: - To collect medical information and gene samples for researchers studying AMD. Eligibility: - Individuals between and 60 and 90 years of age who have AMD in at least one eye. - Individuals between and 60 and 90 years of age who have no AMD in either eye. Design: - This study will involve one study visit. This study visit will last 6 to 8 hours. - Participants will have the following tests and exams as part of their study visit: - Full physical exam and medical history - Full eye examination - Laser scan of the eye - Retina function test - Vision sensitivity test - Optional blood sample (for genetic study) - No treatment will be provided as part of this study.
The aim of the study proposed in Dijon is above all to focus on the possible relationship between age-related ocular pathologies (AMD and glaucoma) and et les degenerative neurological and cardiac pathologies. The principal objective is to seek in subjects who have undergone cerebral MRI and echocardiography, associations between the thickness of postganglionic fibers measured by Optical Coherence Tomography at the 7th year (n=1500) and signs of cerebral impairment (psycho-cognitive tests, circulation time, MRI signs). This association will be studied after taking into account the principal environmental (particularly dietary) and genetic risk factors.
