Filter by:Diabetic macular oedema (DME) is the main cause of visual impairment (or visual acuity) in patients with diabetic retinopathy, as it leads to progressive thickening of the retina, which in the long term leads to progressive death of the photoreceptor cells. It is therefore important to continue to treat macular oedema that has been progressing for several months or even years (resistant DME). The management of DME necessarily involves controlling diabetes (improving glycated haemoglobin levels) and blood pressure, but this is often not enough. Thus, when DME is significant and leads to a decrease in visual acuity, treatments are administered directly into the eye (intravitreal injections). For some years now, corticosteroids have been injected into the vitreous body (the gel that fills the eyeball) through the white of the eye for their anti-inflammatory properties. Indeed, these drugs improve the permeability of the retinal vessels and thus reduce oedema. These intravitreal implants are most often used in patients who have already undergone cataract surgery (pseudophakic) because corticosteroids also tend to aggravate a cataract. Currently, there are two implants containing corticosteroids that can be injected: the dexamethasone implant and the fluocinolone acetonide implant. These two implants have different properties, particularly with regard to their duration of action. Today, the overall management at 3 years and the quality of life associated with the treatments deserve to be evaluated. This study is the first multicenter controlled trial comparing the two reference corticosteroid treatments in terms of overall cost of treatment and follow-up and patient quality of life, while considering their efficacy and side effects. This evaluation will make it possible to precisely define the respective place of each implant in the management of resistant DME.
This pilot study aims to establish that treatment with near infrared light (NIR) reduces cystic macular oedema in patients with a retinal vein occlusion.
The duration of diabetes is directly related to eye complications. Diabetic retinopathy affects 80 percent of those who have had diabetes for 20 years or more. At least 90% of new cases can be reduced with proper treatment and monitoring of the eyes. The longer a person has diabetes, the more likely it is to develop diabetic retinopathy. Each year in the United States, diabetic retinopathy accounts for 12% of all new cases of blindness. It is also the leading cause of blindness in people between the ages of 20 and 64. The most important complication of diabetes leading to vision loss is diabetic retinopathy. Depending on this, macular edema, bleeding into the retina and vitreous,neovascular glaucoma can cause blindness. Diabetic retinopathy (DR) is a leading cause of vision-loss globally. Of an estimated 285 million people with diabetes mellitus worldwide, approximately one third have signs of DR and of these, a further one third of DR is vision-threatening DR, including diabetic macular edema (DME). Diabetic retinopathy is a retinal disease that can often be stopped with early diagnosis, but if neglected, it can lead to severe vision loss, including permanent blindness. Diabetes has high morbidity and there are millions of people who should be screened for diabetic retinopathy (DR). Annual eye screening is recommended for all diabetic patients since vision loss can be prevented if DR is diagnosed in its early stages. Currently, the number of clinical personnel trained for DR screening is less than that needed to screen a growing diabetic population. Therefore, the automatic DR screening system will be able to screen more diabetic patients and diagnose them early. EyeCheckup is an automated retinal screening device designed automatically analyze color fundus photographs of diabetic patients to identify patients with referable or vision threatening DR. This study is designed to assess the safety and efficacy of EyeCheckup. The study is a single center study to determine the sensitivity and specificity of EyeCheckup to diabetic retinopathy. EyeCheckup is an automated software device that is designed to analyze ocular fundus digital color photographs taken in frontline primary care settings in order to quickly screen for diabetic retinopathy (DR).
This study aimed to compare intravitreous conbercept alone with conbercept plus intravitreous triamcinolone acetonide in DME eyes which showed limited response to anti-VEGF treatment after one injection.
The knowledge of the pathogenesis of retinal affections, a major cause of blindness, has greatly benefited from recent advances in retinal imaging. However, optical aberrations of the ocular media limit the resolution that can be achieved by current techniques. The use of an adaptive optics system improves the resolution of ophthalmoscopes by several orders of magnitude, allowing the visualization of many retinal microstructures: photoreceptors, vessels, bundles of nerve fibers. Recently, the development of the coupling of the two main imaging techniques, the Adaptive Optics Ophthalmoscope with Optical Coherence Tomography, enables unparalleled three-dimensional in vivo cell-scale imaging, while remaining comfortable for the patients. The purpose of this project is to evaluate the performance of this system for imaging micrometric retinal structures.
RGX-314 is being developed as a novel, potential one-time gene therapy treatment for the treatment of diabetic retinopathy, a chronic and progressive complication of diabetes mellitus. Diabetic retinopathy (DR) is a sight-threatening disease characterized in the early stages by neuronal and vascular dysfunction in the retina, and later by neovascularization that leads to further deterioration of functional vision. Despite the availability of current treatments, diabetic retinopathy remains the leading cause of vision loss in working-age adults, those between the ages of 20 and 74. Existing treatment with anti-VEGF agents, although shown to be effective, are limited by short therapeutic half-lives, which then require frequent intravitreal injections over the patient's lifetime, resulting in increased risk of associated adverse events and significant treatment burden. Due to the burden of treatment, patients often do not closely adhere to treatment regimens and experience sub-optimal outcomes and a decline in vision. RGX-314 is being developed as a potential one time treatment for diabetic retinopathy, which may deliver advantages over conventional treatments, such as potentially providing a longer duration of therapeutic effect and intervening at an earlier stage of the disease.
To investigate the outcomes of patients undergoing bilateral RLE surgery with treatment of dexamethasone intracanilicular insert compared to topical standard care steroid. Desiged to look at patient preference comparing the insert to drops and will also look at patient outcomes including inflammatin and risk of cystoid macular edema post-operatively.
Assessing the efficacy and safety of DEXTENZA, sustained release dexamethasone 0.4 mg inserts following 27 gauge vitrectomy with internal limiting membrane peel
The purpose of the investigator's study is to evaluate the efficacy and safety profile of the pro re nata (PRN) regimen to 12 months by using intravitreal dexamethasone implant in eyes with treatment-naive diabetic macular edema patients.
Intravitreal injections of Ranibizumab will be applied in all patients according to treatment guidelines. The experimental group will receive additional targeted laser photocoagulation of the peripheral areas of capillary non-perfusion (up to 4 laser treatments within 1st year of the study). Based on the long-term observation after CoRaLa I study an importantly shorter duration of treatment and a relevant reduction of the total number of re-injections in RL patients is expected.
