Active clinical trials for "Macular Degeneration"

Assess the performance and usability of the RHMS Visual Acuity Module.

The purpose of this observational study lies in the analysis of a treat-and-extend injection scheme with intravitreal aflibercept (i.e. injection into the eye), as applied in routine practice in previously untreated patients diagnosed with wet age-related macular degeneration.

With this follow up physician survey researcher want to collect the same data from all participants of the study using a highly structured questionnaire. The questionnaire will gather information related to physician characteristics and experience with Aflibercept, as well as assess physicians' knowledge and understanding of storage and preparation, proper injection technique, and the risks associated with Aflibercept injection into the eye (intravitreal injection). Analysis will be done using descriptive statistics.

The goal of this is to evaluate the biomechanical properties of hypotonous eyes with vertical anterior corneal striae and/or hypotony maculopathy compared to hypotonous eyes without striae.

The study was a retrospective, cross-sectional, descriptive study of patients with wet AMD who enrolled in the brolucizumab Patient Support Services (PSS) program. Evidence was generated to describe their baseline demographic and clinical characteristics.

This was a retrospective cohort study to assess the treatment history, demographic characteristics, clinical characteristics, and early treatment patterns of patients who received brolucizumab for neovascular age-related macular degeneration using IRIS Registry.

The study hypothesis is that patients with dry age-related macular degeneration experience visual function impairments such as defects in dark adaptation, glare intolerance, poor light transition and reading in low lighting conditions. Studies have shown that patients in the early phases of AMD with normal visual acuity commonly reported difficulty with these visual functions but there have been no systematic studies evaluating these deficits in this population. This prospective, exploratory study will include up to 130 patients with dry AMD and 60 controls. These patients will undergo the following non-invasive visual function testing: microperimetry with eye tracking low luminance visual acuity specialized color vision (cone-specific) contrast testing and night vision testing. High-resolution spectral domain optical coherence tomography (SDOCT) images will be taken of the central retina using the Spectralis OCT unit. The values of visual function tested will be correlated with the findings on SDOCT (volume/amount of drusen present in early AMD). There are no known risks to the subjects beyond what is normal for standard examinations of the eye, visual function testing and standard ocular photographic procedures.

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.

This is an open-label study assessing electrophysiologic testing of the retina with Electoretinogram (ERG) /Electrooculogram (EOG) tests in patients with exudative age-related macular degeneration (AMD). The standard FDA-approved treatment for wet AMD is ranibizumab (Lucentis). This study focuses on the ERG and EOG tests to evaluate retinal responses to ranibizumab treatment in AMD.

The FORESEE HOME is used in the recent years to detect Age-related Macular Degeneration (AMD) lesions. The device is capable of differentiation as to stages of AMD and early detection of changes including choroidal neovascularization (CNV) The Foresee HOME demonstrates a high level of sensitivity and specificity as to the different stages of AMD including newly diagnosed or early detection of CNV. The OCT May be use as well to identify choroidal neovascularization (CNV). Comparison between the two methods will allow better understanding of both devices. The FORESEE HOME can use as an assessment tool for the progression and success of the treatment given to AMD lesions. Therefore, evaluation the size and the location of the treated lesions may serve as an additional tool.
