Filter by:It will investigate a novel treatment approach for diabetic macular edema (DME), which causes vision impairment in diabetic patients. It will focuse on the efficacy and safety of administering triamcinolone acetonide via suprachoroidal injection, targeting the space between the sclera and choroid.
The Farseeing Study will explore long-term effectiveness, safety, and treatment patterns among patients being treated with faricimab in real-world, routine clinical practice in China. It is a primary data collection, non-interventional, prospective and retrospective, multi-center study designed to collect real-world, long-term data to gain clinical evidence on faricimab, by observing cohorts of patients with neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), and retinal vein occlusion (RVO) who are receiving treatment with faricimab.
This study plans to compare the accuracy of artificial intelligence (AI)-assisted fundus images with other ophthalmic devices such as optical coherence tomography (OCT) and fundus fluorescence angiography (FFA) in the diagnosis of diabetic retinopathy and diabetic macular edema.
Researchers are looking for a better way to treat people who have diabetic macular edema. Diabetic macular edema (DME) is a diabetes-related eye disorder. In DME, the macula, which is the central part of the retina at the back of the eye, swells up resulting in vision problems. This happens due to leakage of fluid from damaged blood vessels. The study treatment, 8 milligram (mg) aflibercept is injected into the eye. It works by blocking a protein called vascular endothelial growth factor (VEGF) which causes abnormal growth and leakage of blood vessels at the back of the eye. A lower dose of aflibercept (2 mg) is already approved for the treatment of DME. Based on the findings of another study, the higher dose of aflibercept (8 mg) is expected to reduce the frequency of injections required for treating DME while being equally safe and working as well as the lower dose. The higher dose could make it easier to treat DME and improve quality of life for people with DME. The main purpose of this study is to learn if high-dose (8 mg) aflibercept given every 16 weeks works as well as low-dose (2 mg) aflibercept given every 8 weeks in Chinese participants. For this, the researchers will compare the change in participants' 'best corrected visual acuity' (BCVA) after 48 weeks of starting the treatment. BCVA is the clearest vision a participant can have with the help of corrective lenses, such as glasses. It will be measured by the number of letters the participant can read on an eye chart. This is known as their Early Treatment Diabetic Retinopathy Study (ETDRS) letter score. Participants will be randomly (by chance) assigned to one of two treatment groups to receive study treatment as an injection into the eye up to Week 56: - 2 mg aflibercept every 8 weeks after receiving 5 initial monthly doses - 8 mg aflibercept every 16 weeks after receiving 3 initial monthly doses Each participant will be in the study for around 63 weeks with up to 18 visits to the study site. This includes: - one visit up to 21 days before the treatment starts during which the doctors will confirm that the participant can take part in the study - 16 visits during which the treatment will be given. Most of these visits will have a gap of 4 weeks except for one visit that will happen a few days after the previous visit - one visit 4 weeks after the treatment ends During the study, the doctors and their study team will: - check the participants' vision and their overall eye health using different eye tests - check participants' health by performing tests such as blood and urine tests - ask the participants questions about the disease and study treatment and how these impact their quality of life - ask the participants what adverse events they are having An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective of whether they think they are related to the study treatment. Access to study treatment after the end of this study is not planned. Participants can switch to available approved treatments for DME.
The purpose of this pilot study is to evaluate different imaging parameters in patients with previously treatment-naive DME and ME due to RVO before and after treatment with dexamethasone implant, in order to find specific retinal inflammatory and microvascular biomarkers that may be predictive of treatment outcome.
1. assessment the outcomes of vitrectomy on retinal function by mf-ERG (multifocal electroretinogram) and anatomy by OCT (optical coherence tomography) in patients with tractional diabetic macular edema (TDME) . 2. To correlate the postoperative corrected distance visual acuity (CDVA) with the mf-ERG and OCT findings following vitrectomy surgery for TDME.
This is an open-label pilot device study. The aim of the study is to evaluate the safety and performance of Everads Injector following single injection of suspension approved for ocular use into the suprachoroidal space. The study population is patients diagnosed with diabetic macular edema (DME) that were previously treated. 10 adult subjects are expected to be enrolled based on the inclusion-exclusion criteria. The study will involve 6 visits during a period of 6 weeks
Macular edema in diabetes, defined as retinal thickening within two disc diameters of the center of the macula, results from retinal microvascular changes that compromise the blood-retinal barrier, causing leakage of plasma constituents into the surrounding retina and consequently retinal edema. Thickening of the basement membrane and reduction in the number of pericytes are believed to lead to increased permeability and incompetence of the retinal vasculature. This compromise of the blood-retinal barrier leads to the leakage of plasma constituents into the surrounding retina with subsequent retinal edema. Hypoxia produced by this mechanism can also stimulate the production of vascular endothelial growth factor (VEGF). Vascular endothelial growth factor (VEGF) increases retinal vascular permeability, causes breakdown of the blood-retina barrier and results in retinal edema. Diabetic macular edema (DME) is the most common cause of visual reduction in patients with Diabetes Mellitus. The prevalence of DME globally is around 6.8 %. Diabetic Retinopathy (DR) is the most common microvascular complication of diabetes and the leading cause of blindness worldwide. DME is a complication of diabetic retinopathy that affects the macula, which is located at the center of the retina and responsible for central vision. Bangladesh is the 10th country in the world for the number of adults living with diabetes with some 7.1 million (5.3-12.0). In Bangladesh, it is therefore expected that diabetic secondary complications, like DR, will increase along with the rising trend of diabetes mellitus. The use of therapeutic monoclonal antibodies has revolutionized in the treatment of many diseases. In recent years, millions of patients have been successfully treated with these biological agents. Ranibizumab is one such therapeutic monoclonal antibody for intraocular use. Ranibizumab is a humanized, recombinant, immunoglobulin G1 monoclonal antibody fragment against vascular endothelial growth factor A (VEGF-A) and thus prevents choroidal neovascularization. The small size of ranibizumab allows for enhanced diffusion into the retina and choroid.
The goal of this prospective multicenter open label study is to evaluate the efficacy and safety of intravitreal injection Conbercept (IVC) for the treatment of diabetic macular edema (DME) combined with severe nonproliferative diabetes retinopathy (sNPDR). The main questions it aims to answer are: - mean changes in best corrected visual acuity (BCVA) and central macular thickness (CMT) in comparison with baseline at 12 months after initial treatment - proportion of eyes with visual gain ≥15 letters in Early Treatment Diabetic Retinopathy Study (ETDRS) chart and ≥2-step improvement in Diabetic Retinopathy Severity Scale (DRSS) score after 12 months of the treatment - proportion of eyes actually underwent PRP treatment after 3 and 12 months of the treatment - mean changes in BCVA and CMT from baseline to monthly follow-up time point - complications and adverse effects
Diabetic retinopathy (DR) is one of the most serious microvascular complications of diabetes. Early diagnosis and treatment of diabetes is the key to prevent visual impairment in DR patients. This study aims to use a non-targeted metabolomics detection technique combined with ultra-high performance liquid chromatography time-of-flight mass spectrometry to analyze the metabolomics profile in aqueous humor sample of DR patents, and further explore the mechanism of the relationship between differential metabolites and their metabolic pathways with NLRP3 activation in DR inflammatory damage. DR patients with macular edema will receive anti-vascular endothelial growth factor (anti-VEGF) treatment; these patients will be divided into two groups: responders group and non-responders group.
