Active clinical trials for "Macular Degeneration"

The objective of this surveillance is to collect information about 1) adverse drug reaction not expected from the LPD (unknown adverse drug reaction), 2) the incidence of adverse drug reactions in this surveillance, and 3) factors considered to affect the safety and/or efficacy of this drug.

To assess effectiveness of Macugen for treatment of neovascular age-related macular degeneration by measuring the evolution of visual acuity. Treatment duration, frequency of administration and combination with other treatments will also be evaluated.

The efficacy of laser photocoagulation treatment for diabetic retinopathy has been demonstrated by several National Eye Institute (NEI) sponsored clinical trials. The Diabetic Retinopathy Study (DRS) demonstrated that scatter photocoagulation reduces the risk of blindness from diabetic retinopathy. The Early Treatment Diabetic Retinopathy Study (ETDRS) extended these findings by providing information on when to initiate scatter photocoagulation and by demonstrating that focal treatment was effective in treating macula edema. The Krypton Argon Regression Neovascularization Study (KARNS) showed that scatter photocoagulation with krypton red laser was just as safe and effective as the argon blue-green laser in the treatment of proliferative diabetic retinopathy. Unfortunately, there is little data on the long term effects of photocoagulation on visual function. The first objective of this study is to assess the long term effects of photocoagulation for diabetic retinopathy. A second objective is to provide additional information on the risk of progression of cataracts in persons with diabetes. All patients previously treated with laser photocoagulation (focal and/or scatter) are eligible to participate in this long term study. The first priority will be given to patients who participated in the ETDRS and KARNS because of the wealth of information available regarding the details of their treatment and course after treatment. Study evaluations will include a standard ophthalmic examination, fluorescein angiography, lens and fundus photography.

The proposed regulatory post-marketing surveillance (PMS) study will be planned to collect the safety data of aflibercept intravitreal injection in patients with wet Age-related Macular Degeneration (AMD) in real-life treatment practice The primary objective is: - To collect safety data in wet AMD patients treated with intravitreal aflibercept injection The secondary objective is: - To determine how disease activity is monitored including type and frequency of ocular tests and frequency of injections

Purpose To report the long-term efficacy of patients with neovascular age-related macular degeneration (nAMD) treated with anti-vascular endothelial growth factor (VEGF) in Changhua Christian Hospital in Taiwan. Method Retrospective case series of patients with nAMD that were treated with intravitreal injection of anti-VEGF and had a minimum follow up of 48 months. Every patient was initially treated with 3 loading doses of either bevacizumab or ranibizumab, followed by a loose treat and extend regimen. Eyes were divided into 2 groups according to whether aflibercept was later used as a rescue therapy (group 2) or not (group 1). Patients underwent best-corrected visual acuity (BCVA) testing, optical coherence tomography, and ophthalmic examination at baseline and all the scheduled follow-up visits.

COSMOS-Eye is an ancillary study of the COcoa-Supplement and Multivitamins Outcomes Study (COSMOS; NCT02422745). COSMOS is a randomized clinical trial of cocoa extract supplement (containing a total of 500 mg/d flavanols, including 80 mg (-)-epicatechins), and a standard multivitamin supplement to reduce the risk of cardiovascular disease and cancer among men aged 60 years and older and women aged 65 years and older. This ancillary study is being conducted among participants in COSMOS and will examine whether the cocoa extract supplement or the multivitamin supplement reduces the risk of cataract and AMD, two leading causes of visual impairment in US men and women.

This study was a retrospective cohort study of patients to assess the early insights into real-world safety among wet AMD patients initiating brolucizumab. Evidence was generated to describe their patient characteristics and clinical outcomes. The study was conducted using the IRIS Registry.

RAZORBILL is an observational, multicenter, multinational, open-label, study designed primarily to investigate the influence of automated OCT image enrichment with segmentation information on disease activity assessment in nAMD patients treated with licensed anti-VEGFs

In this multi-center study, possible effects of supplement treatment with oral phenolics on plasma CD-163 and progression of dry and wet age-related macular degeneration (AMD) via evaluating the CD163 before and after the prescription of this drug will be evaluated in patients with dry type AMD and Neo vascular age-related macular degeneration (nAMD). Both AMD subgroups will be recruited. In terms of evaluation of the effects of phenolics (500 mg caplets/day) on AMD progression, patients will be randomized and divided into 2 subgroups i.e. (i) receiving phenolics supplementation; and, (ii) receiving placebo for 1 month. The phenolics/placebo caplets will resemble completely and be encoded at origin; Neither the participants nor the researchers will be informed about the codes until the end of the study.

The purpose of this study is to evaluate the long term safety and tolerability of hESC-RPE cellular therapy in patients with advanced SMD from 1 to 5 years following the surgical procedure to implant the hESC-RPE cells.
