Active clinical trials for "Macular Degeneration"

Demonstrate the ability of the current interactive tutorial and 1-800 support to teach an AMD patient to use the HMP device.

First, to quantify, by means of comet assay analysis, systemic oxidative stress in patients with non-exudative and exudative age-related macular degeneration (AMD) and compare results to healthy controls. Second, to quantify systemic oxidative stress in patients with exudative AMD prior to and after photodynamic (PDT) therapy.

The purpose of this study is to evaluate the usability of the Foresee Home device with intermediate AMD patients.

The macula is the site of central vision within the retina. The retina is oxygenated by the underlying choroid. These tissues are less than 1 mm thick in total. While optical techniques can reveal much about the structure of the retina, ultrasound allows imaging of the choroid and deeper tissues. This study will investigate use of high frequency (20 MHz) ultrasound for imaging of the retina and choroid in patients with age-related macular degeneration, a prime cause of blindness. The investigation will involve use of novel post-processing methodologies to achieve maximum resolution of the fine tissue structures involved in this disease.

To determine whether vitamin E supplementation reduces the risk of cataract and age-related macular degeneration (AMD) in women. To determine whether vitamin C supplementation reduces the risk of cataract and AMD in women. To determine whether beta-carotene supplementation reduces the risk of cataract and AMD in women. To determine whether alternate day, low-dose aspirin reduces the risk of cataract and AMD in women. To identify potential risk factors for cataract and AMD including cigarette smoking, alcohol intake, blood pressure, blood cholesterol, cardiovascular disease, height, body mass index, and diabetes.

This screening protocol is designed to help recruit patients for National Eye Institute (NEI) studies of the retina, such as diabetic retinopathy and macular degeneration. Patients must meet the specific criteria of a research study, and this protocol serves as a first step for admitting patients to a retinal disease study. Candidates will undergo a medical history and comprehensive eye examination. The eye examination includes dilation of the pupils to fully examine the retina. In some studies, photographs of the eye are required. This is done using fluorescein angiography. In this procedure, a dye called sodium fluorescein is injected into the blood stream through a vein. After the dye reaches the blood vessels of the eye, photographs are taken of the retina. Other diagnostic procedures may include physical examination, questionnaires, routine laboratory tests and other standard or specialized tests, as needed. When the screening is completed, patients will be informed of their options to participate in a study. Patients who are ineligible for a current study will be informed of alternative treatments or options. No treatment is offered under this protocol.

This study was a retrospective observational cohort analysis of subjects aged 65 years and older, who underwent bilateral cataract surgery within a single (15 hospital) healthcare system, to determine the association between type (conventional or blue-light filtering) of implanted intraocular lens and survival.

Evaluate the ability and accuracy of the Retinal Health Monitoring System - Retinal Thickness Module (RHMS - RTM).

this is a single In-Clinic Encounter With the Notal Vision Home OCT study. The study population will include up to 50 Age-related Macular Degeneration patients diagnosed with wet NV-AMD in at least one eye at the time of enrollment. All enrolled subjects should have at least one eye with active (wet) CNV (SRF and/or IRF) at the time of enrollment. All subjects will be enrolled at 1 site in the United States. in this study patients will be placed in a room with the Notal Vision Home OCT device and following a completion of a self tutorial will perform 3 unsupervised self-scans on each study eye (with a rest of ~5 minutes between self-scans). at the end of the testing sessions, the subject will be asked to complete subject user questionnaire.

In patients treated for exudative age-related macular degeneration (AMD), diabetes, retinal venous occlusion (OVR), or other conditions causing macular edema, treatments with anti-angiogenic intravitreal injections (IVT) are widely used both for their anti-angiogenic action. Patients often have injections for many years, sometimes monthly or every 2 months. The discontinuation of treatment with repeated injections of anti-angiogenic agents, linked to the COVID-19 coronavirus pandemic will potentially impact the visual acuity, the ophthalmological state and the quality of life of the patients concerned, therefore it is relevant to analyze the consequences the breakdown of usual care in this population.
