Active clinical trials for "Choroidal Neovascularization"

This is a prospective, observational, multi-center, study. The study will be conducted in approximately 12 ophthalmological clinics and practices throughout Greece. It is planned to collect data on treatment of wet Age related Macular Degeneration (wAMD) from about 120 patients for which the decision to treat with intravitreal aflibercept injections is made at the discretion of the attending physician, according to his/her medical practice. Visits will be performed at baseline, aflibercept first injection (if different from enrollment) and at 12 and 24 months. The 12 and 24 month comprise the data collection visits during which any data generated in the period preceding these visits will be recorded. All required information for the purposes of this study will be collected using electronic Case Record Form (eCRF). The web-based electronic data capture (EDC) application will be specifically designed for the needs of the study and will adhere to all applicable data protection regulations and requirements with regard to electronic records. The study observation period for each patient enrolled in this study is the time from the beginning of treatment with intravitreal aflibercept injection up to two years or until discontinuation of intravitreal aflibercept injection-treatment due to any reason including withdrawal of consent or patient loss from follow-up.

Clinical trial investigating the role of hyperspectral imaging in the management of patients undergoing standard clinical treatment for naive neovascular choroidal membranes in age-related macular degeneration.

Identify early markers of choroidal neovascularization (CNV) in the fellow eye of a patient with CNV in the other eye due to age-related macular degeneration with the expectation of being able to identify patients in need of intervention.

Age related macular degeneration (AMD) is a multifactorial disease with a strong genetic component. Most importantly a genetic polymorphism in the gene encoding for the complement factor H (CFH) has been recently identified which is highly associated with an increased risk of developing AMD. This Tyr402His polymorphism located on chromosome 1q31 has been implicated to play a role in the development of the disease. For this purpose a total of 200 patients with wet AMD will be included in the study. As described in detail below, the current study aims to identify potentially non-responders to anti-VEGF therapy based on genetic analysis of VEGF polymorphism and complement factor H polymorphism.

Polypoidal choriodal vasculopathy (PCV) is an ophthalmologic disease, characterized by vascular abnormalities of the walls of small choroidal vessels, reproducing the specific aspect of polyps (cluster aspect). PCV is one of the "boundary-forms" of age related macular degeneration. These vasculopathies can be idiopathic. Following the radiotherapy treatments of active and occult-typed neovessels in Age-Related Macular Degeneration (ARMD), 10% of the patients would present typical polypoidal vasculopathic lesions. These polypoidal secondary lesions have been induced by radiotherapy treatment and may show an increased sensibility to radiation in these patients. Such an increase of radiosensibility is noticed in ataxia telangiectasia syndrome, in relation to the ATM gene mutations. The secondary or idiopathic polypoidal vasculopathic lesions are to be brought closer to telangiectasias in Ataxia Telangiectasia. Considering the iatrogenic component of radiotherapy in the secondary forms of ataxia telangiectasia, it seems legitimate to search for predisposing variants to polypoidal vasculopathies in the ATM gene. Considering the frequency of PCV worldwide, it seems important to identify the predisposing genetic factors of the ATM gene. These biomarkers to the pathology might enable us to offer prevention (reinforced protection against radiations, including light) and to develop therapeutics (recruitment of other kinases, ATM's partners, in the stability and cellular control of DNA).

This is a research study to evaluate the effects of repeated intravitreal injections on bacteria around the eye.

This research project intends to observe patients with high myopia who show pathological retinal changes, in order to evaluate more data on the risk factors for developing mCNV within this research project population in Germany.
