Active clinical trials for "Macular Degeneration"

The objective of the study was to investigate the influence of a intervention with lutein und zeaxanthin from crucifers on the optical density of the macular pigment of patients with non exudative age-related maculopathy. It is hypothesized that the applied study beverage elevates plasma concentrations of the administered xanthophylls and the optical density after 4 weeks of intervention.

This clinical study is a phase 1 study which carried out to to evaluate the safety, pharmacokinetics and tolerability of multiple intravitreal injections of BCD-021(bevacizumab biosimilar candidate manufactured by CJSC BIOCAD, Russia) when used in patients with neovascular wet age-related macular degeneration.

The aim of this study is to investigate the early changes in macular thickness, corneal thickness and intraocular pressure in young women undergoing surgical menopause. Methods: Eye findings of 30 surgical menopausal (Postoperative 3-6 months) and 48 natural menopause and 22 healty women (control) were evaluated using OCT. Women with no known eye disease, no chronic disease (Diabetes Mellitus, Cardiac Disease any Autoimmune disease) and no migraine in addition to non smokers were included in the study. Women using any hormone and obese women ( BMI >25 kg/m2) were excluded. Macular and corneal thickness and intraocular pressure (IOP) were measured in both eyes of the women

The purpose of his study is to evaluate the long term safety and tolerability of MA09-hRPE cellular therapy in patients with advanced dry Age-Related Macular Degeneration (AMD) from one to five years following the surgical procedure to implant the MA09-hRPE cells.

The study will be an observational, cross-sectional study of knowledge, understanding, and self-reported behavior among a sample of physicians and patients with recent aflibercept experience in a total of up to five European countries.

Objective: To learn more about AMD. Eligibility: People ages 55 and older with any of the following: AMD or changes in the retina that put them at risk for AMD RPD Healthy eyes Design: Participants will be screened with: Eye exam: The pupil will be dilated with eye drops. Eye pressure and movements will be checked. Pictures will be taken of the inside of the eye. Reading an eye chart. Optical coherence tomography (OCT): The eyes are dilated. A machine measures the thickness of the retina. Participants will have a first visit that includes: Repeat of screening procedures Medical history Physical exam Questions about vision and general health Dark adapted fundus perimetry: Participants sit in the dark for 40 minutes. Then they sit at a machine that shines lights in the eyes. Dark adaption testing: Participants sit in the dark for 45 minutes. The pupils are dilated. They push a button when they see light in a machine for up to 1 hour. Participants will have annual visits for up to 5 years to repeat the tests in the first visit. Participant data may be shared for other research. ...

We propose to undertake a retrospective review of approximately 200 patients with a diagnosis of exudative macular degeneration treated with triple combination therapy (Bevacizumab, Dexamethasone and Photo-dynamic therapy) during the years of 2006 to 2010 at The Retina Center and compare those results with an additional group of approximately 200 patients also treated with triple combination therapy and 20 mg of daily oral zeaxanthin.

Patient-reported vision-related quality of life (QOL) outcomes are increasingly incorporated into clinical trials of new treatments for age-related macular degeneration (AMD). In patients with central visual field defects they often do not correlate with distance visual acuity changes as evaluated according to the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol. Therefore there is the need for better correlated visual acuity (VA) outcome measures for these patients. In a current big trial for treatment of dry AMD (geographic atrophy) reading speed and low luminance visual acuity are used as outcome measures for the first time. However, limited information is available regarding the associations between distance ETDRS visual acuity, reading speed, low luminance visual acuity, contrast sensitivity, morphological parameters and the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) subscales judged relevant to these measures. Evaluating these correlations could provide the basis for objective study outcome parameters which are better correlated to patient-reported outcomes. Further it increases the understanding of the impact of visual impairment on activities and functioning in patients with eye diseases. There is an immediate benefit to the study patients, as they might gain information regarding their individual results regarding objective VA measures, contrast sensitivity (and their impact on reading ability). Furthermore, the results of the study could be beneficial for future patients due to, e.g., a better understanding of the disease, especially regarding factors which have an impact on their near vision ability and therefore their quality of life. The study could provide a basis to find and include outcome measures which are correlated better with quality of life than ETDRS distance VA for further AMD trials.

In this clinical study researchers want to gain a deeper understanding of treatment consistence under real world conditions over the course of 24 months of Aflibercept injections into the eye for patients suffering from abnormal growth of new blood vessels under the retina (neovascular age-related macular degeneration). The study aims to identify potential reasons that may allow classification of non-consistence as patient or physician driven. They want to describe treatment effectiveness (how well the treatment works) and associations between treatment effectiveness, non-consistence and patient relevant outcomes, such as vision specific quality of life and treatment satisfaction.

The purpose of this prospective interventional study is to compare patient experience, ocular surface irritation, and bacterial colony counts and microbial spectrum between povidine iodine and aqueous chlorhexidine as ocular surface antiseptic prior to intravitreal injection
