Active clinical trials for "Macular Degeneration"

The objective of this study is to compare Cirrus HD-OCT automated measurements of the illumination area under the retinal pigment epithelium (RPE) to expert manual measurements of areas of hypofluorescence typical of geographic atrophy in fundus autofluorescence (FAF) images.

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.

This study is to determine how cognitive deficits (e.g.,verbal fluency deficit) in patients with Age-Related Macular Degeneration (AMD) relate to specific aspects of brain and function. The study team will assess whether the "brain signatures" associated with specific cognitive deficits differ in older adults with and without AMD.

Over the last several years, the standard of care for wet macular degeneration has become treatment with intravitreal injections of ranibizumab (Lucentis, Genentech), administered as frequently as every 4 weeks. In contrast, clinical trials of a soluble VEGF receptor, Aflibercept/VEGF Trap-Eye (Eylea, Regeneron Pharmaceuticals) have demonstrated maintained anatomic and visual improvement with many fewer injections (typically monthly injections for 3 months, followed by every-other-month injections, and as few as 5 injections a year). The purpose of this study is to determine whether patients who have switched from ranibizumab to VEGF Trap-Eye have comparable results.

To conduct a precision study to assess the microperimetry function of the Spectral OCT/SLO. The study will assess variability across measurements taken by three different operator-device configuration across clinical sites, variability between subjects within a given operator-device configuration, and variability within a subject for a single operator-device configuration.

This study is to investigate whether there is an association of the LOC387715/HTRA1 and vascular endothelial growth factor polymorphism with response to treatment with intravitreal ranibizumab injections for patients with polypoidal choroidal vasculopathy.

Determination of the sensitivity and specificity of different combinations of imaging techniques (spectral domain optical coherence tomography, fundus photography and fluorescein angiography) used for the diagnosis of choroidal neovessels complicating age -related macular degeneration. This information will help to determine the choice of the most suitable combination for the above diagnosis.

The FORESEE HOME is intended for the early detection of central and paracentral irregularities (abnormalities) in the visual field, most commonly associated with AMD. However, the device has ability to detect the development of the lesion post treatment and therefore to asses in determination of the next treatment.

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

The study is divided in two stages. The purpose of the first stage is to evaluate the percentage of subjects that can unpack the device, install it, learn the task and calibrate it according to their personal capabilities. The purpose of the second stage is to assess the ability of the subjects to perform reliable tests .
