Active clinical trials for "Macular Degeneration"

This study evaluates the retinal and vascular features in patients with radiation maculopathy under the effects of Ranibizumab intravitreal injections using optical coherence tomography and optical coherence tomography angiography.

In this study, participants will be imaged using two Optical Coherence Tomography (OCT) devices: device N, a standard conventional OCT device with an invention (comfortable chin and forehead rest that can be adjusted to fit each individual's size) attached to the device; and device C, the standard conventional OCT device with no invention attached. The investigators will assess whether the chin and forehead rest attachment (invention) provides a more comfortable experience for patients.

Age-related macular degeneration (AMD) is a leading cause of blindness in people over 50 years old. Neovascular AMD, the most severe form and the most severe is characterized by the appearance, spread and growth of subretinal neovessels. One of the major molecular mediators is the endothelial growth factor vascular (VEGF). Intra-vitreous (IVI) injection of an anti-VEGF may slow the progression of Neovascular AMD and stabilize vision in the majority of cases. Ranibizumab (Lucentis®) is one of the anti-VEGF molecules approved in Belgium to treat neovascular AMD. At the start of its use, ranibizumab was first injected monthly and then according to the "reactive" protocol. Over time, a new strategy of treatment was born: the "treat-and-extend" (T&E). This is 'made to measure' protocol for each patient aiming to reduce the frequency of injections while guaranteeing inactivity of the disease. It starts with the loading dose, i.e. 3 injections given 4 weeks apart. Subsequently, the interval is lengthened by slices of 1 or 2 weeks provided that the visual and anatomical results remain stable. In the event of deterioration, the interval is shortened while keeping a minimum of 4 weeks between each IIV. The efficacy and safety of ranibizumab, when used in a proactive regimen of T&E, has been shown in the CANTREAT randomized controlled trial. However, there is a lack of more data on T&E used in current practice, and particularly on the number of injections and treatment intervals over a minimum treatment period of 24 months. The aim of this retrospective study carried out at the CHU Brugmann Hospital is to determine the number of injections and the intervals necessary to have encouraging results in visual acuity over a treatment period of at least two years.

In people with neovascular age-related macular degeneration (nAMD), the body makes too much of a protein called vascular endothelial growth factor (VEGF). This causes too many blood vessels to grow in a part of the eye called the macula. These blood vessels can damage the macula, causing dark spots and blurriness in central vision. The study drug, aflibercept, works by reducing VEGF levels in the eye.It has already been approved for patients to receive as a treatment for nAMD in a fixed 8-weekly or treat-and-extend dosing regimen after having received 3 monthly doses at the start of treatment. In this study, the researchers want to learn more about how often patients received aflibercept and how their vision changed. The study will include patients with nAMD who had not received treatment to reduce VEGF levels in the eye before. These patients will have started treatment with aflibercept between January 2016 and November 2018. The study will include about 330 men and women who are at least 18 years old. All of the patients had received aflibercept eye injections based on their doctor's instructions. The researchers will use the patients' medical records from January 2016 to November 2020 to measure the following: the number of aflibercept eye injections the patients received how long the patients could wait between treatments the change in the patients' vision how many patients stopped treatment and why. associations between patient and disease characteristics at the start of treatment with the number of aflibercept injections and patient's vision during treatment.

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 Komodo Healthcare Map.

The aim of the study is to find out prevalence of aged-related macular degeneration (AMD) in Slovak Republic. The outcome of the project will be epidemiology survey, prevalence of wet form of AMD in relation to demographic data, patient´s anamnesis, nutrition, co-morbidities etc.

The study aims to investigate the effectiveness of Eylea in patients with wet age-related macular degeneration in routine clinical practice in Germany. The study is purely observational, only data from routine treatment are to be collected. The treatment and treatment conditions are solely at discretion of the treating physician.

The investigators believe that oxygen saturation measurements in the retina may provide more information on how well the retina is working and may detect problems in the retina earlier than the fundus fluorescein angiography (FFA). This may be useful to an ophthalmologist so that they may identify abnormal areas of the retina and commence or change the treatment so that they may prevent irreversible blindness. Most patients with clinically significant macular oedema and/or ischaemic diabetic retinopathy could have either laser or Intravitreal Anti-VEGF injection treatment provided they are counseled about the risks. It is known the Anti-VEGF injections reduce oedema and it is believed that laser treatment of the retina in this condition improves the oxygen supply to the retina and sometimes reverses the damage. It will be useful to take pictures of these treated eyes using the Oxymap spectral retinal camera(s) to see whether the investigators can detect a change in the oxygen saturation in the retina before and after treatment using our oxygen saturation methods.

This is a prospective pilot study to evaluate the usability and applicability of a self monitoring test of visual function with the handheld Health Management Tool (HMT) to remotely monitor neovascular Age Related Macular Degeneration (AMD) to detect a potential change in disease status.

Hypothesis: The use of teleophthalmology for patient screening will result in more rapid patient access for treatment. The use of teleophthalmology to monitor patients with wet AMD post-treatment will result in maintenance of good visual outcomes combined with a reduction in patient travel and improved patients satisfaction in a cost effective manner. Objectives : The Evaluation of Teleophthalmology in AMD project objectives are as follows: To evaluate the efficacy of teleophthalmology in screening patients referred to retina specialists for suspected wet AMD. To compare the "time to treatment/retreatment" with this program with that of patient's entering the system and being followed conventionally to determine the efficacy of teleophthalmology to provide rapid entry/re-entry into treatment programs. To determine the efficacy of teleophthalmology in monitoring patients with wet AMD post therapy. To determine the compliance rate for monitoring wet AMD during follow-up utilizing teleophthalmology. To evaluate the cost effectiveness of teleophthalmology in screening/monitoring wet AMD patients including direct costs to the OHIP system and indirect costs to the patient/caregiver. To assess patient satisfaction with teleophthalmology versus standard clinical care in the monitoring of post-treatment wet AMD. To evaluate teleophthalmology as a tool for communication between community based Optometrists /Ophthalmologists and Retina Specialists.
