Filter by:The purpose of this study is to assess a new treatment pattern for aflibercept. The aim is to achieve and maintain the best benefit of visual function and avoid unnecessary hospital visits. The hypothesis to be tested is whether intravitreous aflibercept given in an 8 week cycle of treatment in year 1 and a capped treat and extend treatment paradigm in year 2 can lead to improved vision and reading speed in eyes with active wet AMD over 2 years while reducing hospital visits.
The purpose of this study is to compare brolucizumab (RTH258) ophthalmic solution for intravitreal (IVT) injection (6 mg) to aflibercept ophthalmic solution for IVT injection (2 mg) in subjects with untreated active choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) in the study eye.
The investigators have developed an image analysis method that can predict the likelihood that a patient with age related macular degeneration (AMD) will progress within 1 year, based on computerized analysis of optical coherence tomography (OCT) images that are routinely acquired in clinical practice on each patient visit to the ophthalmologist. The investigators' goal is to evaluate whether this method will improve the ability to detect AMD earlier and improve visual outcomes in AMD patients by assigning patient risk categories and having patients come back for follow up based on those categories.
This pilot study will evaluate home vision testing using a mobile medical application in participants with diabetic macular edema (DME) or neovascular age-related macula degeneration (nAMD) who receive intravitreal ranibizumab therapy. In the main, decentralized study, participants will be recruited via digital media, advocacy groups, or through their own ophthalmologist. The traditional substudy will evaluate the association between visual acuity and anatomical markers of disease status determined using clinical "gold standard" assessments (certified Early Treatment Diabetic Retinopathy Study [ETDRS] protocol visual acuity and macula optical coherence tomography [OCT]) and the results of home vision testing using the myVisionTrack^TM (mVT) application.
While a fair amount of clinical data on Stargardt disease type 1 (STGD1) have been published, very little is known about Stargardt disease type 4 (STGD4). The ProgStar 04 study is an important opportunity to leverage the infrastructure, clinical trials sites, methods, and central reading center of the ProgStar program to investigate the progression of STGD4 and will help to establish patient cohorts worldwide for future clinical trials.
The purpose of the study is to evaluate the safety and efficacy of intravitreal (IVT) administration of DE-120 in subjects with treatment-naive active subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).
Age-related macular degeneration (AMD) is an acquired retinal pathology affecting the central region of the retina responsible for discrimination between high spatial frequencies (reading), colour vision and the central visual field. The loss of visual acuity which occurs with the onset of AMD significantly affects patients' quality of life. In developed countries, AMD is the leading cause of vision impairment for people aged over 50 years. Its prevalence in Europe in people aged over 65 years is 3.3%. In France, around 2 million people suffer from this disease. In the first stage of the disease it is known as age-related maculopathy (ARM). This early form of the disease can develop into intermediate AMD (stage 3 of the AREDS classification) and then advanced AMD (stage 4 AREDS), which can be atrophic or exudative. In cases of exudative AMD, the intravitreal administration of anti-VEGF drugs can limit the disease's progression. It is therefore vital to adopt a strategy to assess the stage of the disease and provide the appropriate care management at the earliest possible stage. This is even more important for patients with advanced AMD in one eye and intermediate AMD in the fellow eye, as the risk of the fellow eye progressing to the advanced stage within 5 years is between 35% and 53%. Microperimetry is a promising new diagnostic method which combines measurements of light sensitivity, loss of fixation and the anatomy of the retina. It offers a new approach to the functional assessment of retinal damage in patients with AMD, as it precisely correlates anatomical and functional modifications by measuring the loss of sensitivity and macular fixation. It has been shown that the more advanced the patient's AMD is, the further the parameters measured by microperimetry are from the norm. The investigators want to assess the MAIA™ as a means of screening for AMD progression in patients with a high risk of progressing to a more advanced stage (patients presenting one eye with advanced AMD and a fellow eye with stage 3 AMD according to the AREDS classification). The research hypothesis for our proposed study is that the parameters measured using microperimetry will already show abnormal results in the study eye prior to progressing to a more advanced stage of the disease. The use of these microperimetric parameters as predictor of progression would therefore make it possible to screen eyes likely to develop from intermediate to advanced AMD at an earlier stage, and subsequently provide patients who need it with earlier follow-up, preventive treatment or adapted, personalized rehabilitation as appropriate.
The goal is to conduct a 5-year prospective, randomized controlled trial to test an innovative, community-based intervention using posterior and anterior fundus photography of the optic nerve and macula and intraocular eye pressure measurements to improve access and utilization of eye care to detect, treat, and manage high-risk patients with previously undiagnosed glaucoma and other eye diseases. Research shows that subject failure to attend follow-up eye care appointments diminishes any previous benefits of community screenings for glaucoma. Greater adherence to follow-up visits can reduce glaucomatous blindness.
Neovascular Age-Related Macular Degeneration (NV AMD) remains the leading cause of vision loss among people over 65. Intravitreal injections with drugs that block VEGF have revolutionized treatment of NV AMD. However, less than 40% of treated patients have clinically significant imporovement in vision. In this study, we will determine the relative frequency of neovascular subtypes in two groups: 1) a representative, treatment-naive NV AMD patient population, and 2) a population of patients who develop recurrent NV AMD activity while off treatment and assess the frequency of persistent disease activity (PDA) according to specific neovascular morphologic subtypes. This information will clarify the scope of the PDA problem and will identify patients with PDA who may benefit from additional therpeutic strategies.
The purpose of this study is to evaluate the safety, biological activity and pharmacodynamic effect of repeated intravitreal doses of hI-con1 0.3 mg administered as monotherapy and in combination with ranibizumab 0.5 mg compared to ranibizumab 0.5 mg monotherapy in treating patients with choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).
