Active clinical trials for "Macular Degeneration"

The objectives of the study are to demonstrate the equivalence of Xlucane to Lucentis® in treatment of subjects with wet (ie, neovascular) age-related macular degeneration (wAMD).

Age Related Macular Degeneration (AMD) is the leading cause of blindness in North America. This condition causes a progressive loss of central vision, the part of your vision that allows you to read, drive and see images in sharp detail directly in front of you. The wet form of AMD is characterized by the growth and leakage of small blood vessels into the choroid layer of the eye, or the back of the eye. These leaking blood vessels disrupt the structure and function of the eye, causing loss of vision, particularly the sharp vision created by the macula area of the eye. Currently, the best treatment for wet AMD is a series of injections of an anti-vascular endothelial growth factor (anti-VEGF) drug, ranibizumab (Lucentis). The clinical response to treatment is varied. Approximately 70% of patients see a moderate vision gain (3-line gain on a visual acuity chart), but there are 30% who do not see a similar improvement in vision. There is no way to identify those patients who will respond with significant vision gain versus those who will not experience moderate vision gain. Recent research into AMD has demonstrated that genetic mutations are proving to be key risk factors for patients developing wet AMD, with up to 80% of wet AMD cases explained by inherited genetic variations. Scientists have theorized that there may be a genetic difference between those patients who see significant responses to treatment and those who do not. The investigators will be testing participant's genetic profile using the Macula Risk test and following their progress through the standard treatment for wet AMD over the course of this study. This study aims to demonstrate the association between known genetic variations and patient responses to treatment.

The addition of an anti-inflammatory agent could be a valid option for controlling choroidal neovascularization, as simply inhibiting VEGF addresses neither the multifactorial pathogenesis of choroidal neovascularization nor the underlying cause of VEGF production.

We are comparing the patient experience between the standard 30 g needle to the smaller 33 g needle for intravitreal injections of ranabizumab or aflibercept for age related macular degeneration, diabetic macular edema, or retina vein occlusions.

200 eyes with each subtype of neovascular age-related macular degeneration will be included in this study and 3 years after the initial intravitreal bevacizumab, best-corrected visual acuity (BCVA) will be measured using Snellen charts at 6m. Central retinal thickness (CRT) will be measured using Stratus OCT and Cirrus SD-OCT (Zeiss). Data of treatment-naive eyes (group 1) were compared to the data of eyes that had undergone prior treatment with photodynamic therapy with verteporfin and intravitreal triamcinolone acetonide (group 2).

This study compares the use of intravitreous triamcinolone and laser therapy to treat maculopahty in patients with type 2 diabetes mellitus in a short-tem period of 6 months

The goal of this pilot study is to validate the use of the combination of Lucentis (ranibizumab) and Visudyne (verteporfin) in the treatment of choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) and to explore the use of a volumetric analysis of the CNV lesion to determine disease activity, response to therapy, and as a tool for determining the need for retreatment.

The purpose of this study is to evaluate two surgical interventions in patients with AMD.

This is a phase III, multicenter, randomized, double-masked, active treatment-controlled study of intravitreally administered ranibizumab compared with verteporfin (Visudyne) photodynamic therapy (PDT) in treating subfoveal neovascular mascular degeneration.

The purpose of this study is to determine if emixustat hydrochloride reduces the rate of progression of macular atrophy compared to placebo in subjects with Stargardt disease. Funding Source -- FDA OOPD
