Active clinical trials for "Macular Degeneration"

This non-interventional, retrospective, observational, noncomparative, non-randomized, single-arm, multi-centre study included patients (≥50 years) diagnosed with neovascular age-related macular degeneration (nAMD) in at least 1 eye. Anonymized data of patients treated with brolucizumab intravitreal injection (IVI) who had received the first dose of brolucizumab between 01 October 2020 and 31 March 2021 was collected. Patients could either be treatment-naïve or previously treated with single or a combination of other IVI of anti-vascular endothelial growth factors (VEGFs). The primary outcome measure was the change in fluid levels (intra-retinal fluid [IRF], sub-retinal fluid [SRF], and pigment epithelial detachment [PED]) from baseline to Month 3. Secondary outcome measures included change in best-corrected visual acuity (BCVA) and central retinal thickness (CRT), number of brolucizumab injections, and safety (number of adverse events [AEs]). Descriptive statistics were tabulated for the demographic and clinical characteristics as well as outcome variables.

Blindness can be caused by many ocular diseases, such as diabetic retinopathy, retinal vein occlusion, age-related macular degeneration, pathologic myopia and glaucoma. Without timely diagnosis and adequate medical intervention, the visual impairment can become a great burden on individuals as well as the society. It is estimated that China has 110 million patients under the attack of diabetes, 180 million patients with hypertension, 120 million patients suffering from high myopia and 200 million people over 60 years old, which suggest a huge population at the risk of blindness. Despite of this crisis in public health, our society has no more than 3,000 ophthalmologists majoring in fundus oculi disease currently. As most of them assembling in metropolitan cities, health system in this field is frail in primary hospitals. Owing to this unreasonable distribution of medical resources, providing medical service to hundreds of millions of potential patients threatened with blindness is almost impossible. To solve this problem, this software (MCS) was developed as a computer-aided diagnosis to help junior ophthalmologists to detect 13 major retina diseases from color fundus photographs. This study has been designed to validate the safety and efficiency of this device.

In this cross-sectional study of patients with wet AMD who received ≥1 anti-VEGF injection (excluding brolucizumab), evidence was generated to describe the period prevalence of specific ocular AEs. The study was conducted using the IRIS Registry, and all results were based on the study period from 01/01/2019 to 12/31/2019.

Age-related macular degeneration (AMD) is a leading cause of blindness in people over 50. Neovascular AMD, the most serious and severe form, is characterized by the appearance, spread and growth of subretinal new vessels. One of the major molecular mediators is vascular endothelial growth factor (VEGF). Intra-vitreous (IVI) injection of an anti-VEGF can slow the progression of neovascular AMD and stabilize vision in the majority of cases. Aflibercept (Eylea®) is one of the anti-VEGF molecules approved in Belgium to treat neovascular AMD. At the start of its use, aflibercept was first injected monthly and then according to the PRN "reactive" protocol (Pro Renata). Over time, a new treatment strategy has emerged: the "treat-and-extend" (T&E). This is individualized patient care, the objective of which is to reduce the frequency of injections while ensuring inactivity of the disease. This begins with the loading dose, i.e. 3 injections given 4 weeks apart. Thereafter, the interval is lengthened in increments 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 IVI. The efficacy and safety of aflibercept, when used in a proactive T&E regimen, was demonstrated in the randomized controlled trial, ALTAIR. However, data on T&E used in practice is still lacking. routine, and particularly the number of injections and treatment intervals over a minimum 24 month treatment period. The aim of this retrospective study carried out at the CHU Brugmann is to determine the number of injections and the intervals necessary to have encouraging results in terms of visual acuity, over a treatment period of at least one year.

Neovascular age-related macular degeneration (nAMD) is characterized by the abnormal growth of blood vessels from the choroid into the subretinal space which leads to sub- and intraretinal fluid accumulation, hemorrhages and subretinal fibrosis with progressive loss of central vision. Intravitreal anti-VEGF treatment is the standard of care. Intravitreal anti-VEGF application might temporarily increase intraocular pressure due to a volume effect. It remains unclear if repeated injections might have an impact on retinal capillary perfusion. Therefore this study aims to investigate the vascular microcirculation differences between patients who received longterm intravitreal Anti-VEGF treatment and patients who recently started Anti-VEGF treatment using Optical Coherence tomography Angiography (OCTA).

Background: - The Age-Related Eye Disease 2 Study (AREDS2) looked at two eye diseases. These were age-related macular degeneration (AMD) and cataracts. Participants in that study took supplement pills and some participants had additional pictures taken of their eyes. That study is now over. Researchers want to do a follow-up study after participants finish taking the pills, to see if they cause long-term effects on AMD. This study will be combined with follow-up visits of the AREDS2 study if possible. Objectives: - To learn more about the effect of oral supplements on AMD. Eligibility: - People who completed the AREDS2 study. Design: Participants will have up to 2 study visits over 6 18 months. Each visit will last up to 5 hours. The visits will be combined with annual follow-up visits in the AREDS2 study if possible. At each visit, participants will undergo an eye exam and photography. The eye exam includes testing sight, measuring eye pressure, and checking eye movements. To examine the inside of the eye, the pupil will be dilated with eye drops. Photographs of the inside of the eye may be taken during the eye exam and while the eyes are dilated. A contact lens may be placed on the eye briefly to look at the retina at the back of the eye.

The most common goal for patients with vision loss who present for vision rehabilitation is to be able to read. The video magnifier (a device which combines a video camera and a screen to view the print being magnified) is the device which most often allows low-vision individuals to read successfully for extended periods of time. Previous studies on the outcomes of vision rehabilitation have not identified which components of the vision rehabilitation are effective. The hypothesis of this project is that providing a video camera magnifier, with basic training in operating the device, will allow patients to enhance both objective reading ability and subjective report of reading competence.

Currently the best treatment for "wet" macular degeneration involves regular injections of Ranibizumab (Lucentis). In the initial clinical trials, the drug was injected into the eye every month. Since then a number of studies have found similar benefits when the drug is given with a fixed number of injections initially and then with further injections only when needed. This approach has been adopted in the UK, following recommendation by the National Institute for Clinical Excellence (NICE). Although this approach reduces the expense and risk of un-necessary treatment, it does require regular hospital assessment of disease activity to determine if a repeat injection is required or can be deferred. The hospital assessment is time-consuming, inconvenient and the large number of assessments can cause delays in hospital follow-up. Using three different assessment criteria to monitor disease activity at home, the investigators plan to see if home monitoring is as good as hospital assessment. The investigators have already identified that many patients dislike the lengthy hospital assessment visit and would welcome the opportunity to do some of the monitoring of disease activity at home. The investigators have also shown that they understand and can complete each of the home assessment tests. In this pilot project, the investigators aim to get an idea of how reliable home monitoring can be in a small sample of just over 30 patients. The data that the pilot project generates will be used to influence and to help plan a subsequent, larger, national study to be submitted for funding to the National Institute for Health Research.

The Visual Pathfinder (LACE inc.) offers a non- invasive, patient- centered visual rehabilitation system based on an acoustic biofeedback. The investigators wanted to evaluate its usefulness in the improvement of visual function in visually impaired patients with high myopia.

Vision testing is a fundamental part of every optometry and ophthalmology assessment. Traditional vision testing charts are not able to measure vision below a certain level. Vision in this range is classified as counting fingers (CF), hand movements (HM) and light perception (LP). These measures are not very accurate or easily quantifiable. They are also poorly understood in terms of impact on quality of life. This study aims to assess new methods for measuring the vision of patients with very low vision.
