99 Clinical Trials for Various Conditions
The purpose of this research is to evaluate the effectiveness of vitrectomy for the treatment of diabetic macular edema. Diabetes is known to cause retinal blood vessels to leak, leading to swelling of the central retina (macula), and decreased vision. Removing the vitreous gel with vitrectomy surgery is known to decrease the swelling caused by diabetes. Diabetic retinopathy is often treated with laser or injections of medicine in to the eye.
Background and Objective: To evaluate the efficacy of cooled versus room temperature artificial tears in reducing post intravitreal injection (IVI) ocular discomfort. Patients and Methods: Patients receiving IVI were randomized to either cooled or room temperature tears intervention groups. Both groups rated their ocular discomfort following IVI before intervention and again after administration of cooled or room temperature tears.

The DRAGONS study is a non-interventional, prospective study that will 1. characterize disease state biomarker (including cytokines, KKS metabolites, and cell adhesion molecules) levels from aqueous humor of subjects with various stages of diabetic retinopathy (DR) and diabetic macular edema (DME) as well as other retinal pathologies, and 2. correlate a broad array of aqueous humor disease state biomarkers with DR severity, DME anti-vascular endothelial growth factor (VEGF) responsiveness, and other retinal pathologies.
Study GR41675 is a Multicenter, Randomized Study in Participants with Diabetic Retinopathy (DR) Without Center-Involved Diabetic Macular Edema (CI-DME) to Evaluate the Efficacy, Safety of the Port Delivery System with Ranibizumab (PDS) Relative to the Comparator Arm
The complicated schedules for administering topical steroid eye drops combined with forgetfulness and physical difficulties instilling the drops may compromise compliance; which in turn could increase the risk for secondary complications such as PME post-cataract surgery, especially in a high-risk diabetic population. Dextenza, a sustained- release steroid insert, could help preclude adherence difficulties and provide better bioavailability, being as effective as, or more effective than steroid drops in preventing PME. The aim of this study is to assess the incidence of PME in diabetic patients undergoing cataract surgery when comparing the Dextenza insert to topical prednisolone acetate 1% drops.
The purpose of this study is explore if a partnership and screening program put in place between a busy retina practice and their referring diabetes care offices can improve diabetic retinopathy and diabetic macular edema diagnosis, care and overall diabetes control in patients with diabetic eye disease.
Evaluation of safety and tolerability of a single injection of NOVA63035 "Corticosteroid" administered at one of four doses in patients with diabetic macular edema (DME) secondary to diabetic retinopathy
The purpose of the study is to determine whether concentrations of FOV2304 (high dose or low dose) administered in the eye are more effective than placebo in treating patients with diabetic macular edema, following 12 weeks of treatment.
The purpose of this study is to determine the safety and tolerability of MS-R001 at escalating doses in patients with diabetic macular edema secondary to diabetic retinopathy
Patients with diabetic macular edema (DME) sometimes must undergo vitrectomy surgery (PPV) for diabetic and non-diabetic related issues. Patients may have improved DME with anti-VEGF therapy and ranibizumab has been found to reduce central macular thickness (CMT) with anti-VEGF therapy following vitrectomy. Those patients still require intravitreal injections but the pharmacokinetics of a vitrectomized eye are different than those eyes that have not undergone vitrectomy. The clearance of protein molecules is quicker in vitrectomized eyes so these patients may be more refractory to standard of care anti-VEGF therapy. In rabbit models, the half-life of both bevacizumab and ranibizumab were reduced by a factor 1.8 and 1.3, respectively, after pars plana vitrectomy. In a study examining intravitreal triamcinolone acetonide in human eyes, the half-life was found to be 18.6 days in non-vitrectomized eyes and 3.2 days in vitrectomized eyes, but there was considerable intrasubject variation. Patients with various disease states, including neovascular age-related macular degeneration (nAMD) have been managed with monthly anti-VEGF therapy successfully after vitrectomy surgery. Another study performed by the DRCR net showed that patients with DME treated with anti-VEGF are not affected in the long term if they had had a previous vitrectomy. High dose aflibercept may improve anatomic and visual outcomes in this patient population. Also, high dose aflibercept may allow for longer treatment intervals in these vitrectomized eyes.
The objective of this trial is to assess the safety, efficacy, and tolerability of RZ402 in patients with Diabetic Macular Edema.
Diabetes affects over 37 million Americans and over 530 million people globally. Each diabetic patient needs at least one retinal exam per year starting immediately at the time of diagnosis if they have Type II diabetes (and starting at 5th year after disease onset if they have Type I diabetes). However, majority of diabetic patients do not get their eye exam due to multiple prohibitive factors such as cost, transportation, difficulty of taking time off from work, and inconvenience, amongst others. As a result, diabetes is the most common cause of visual impairment and blindness in working age adults in the United States and globally. Early detection via effective screening can prevent diabetes-related blindness. However, there are multiple barriers to screening. This prompted the development of RETINA-AI Galaxy™ v2.0, an automated Software as a Medical Device that screens for diabetic retinopathy in the primary care setting. This observational study was designed to validate the safety and efficacy of the RETINA-AI Galaxy™ Software-as-a-Medical-Device.

Treatment of diabetic macular edema with intravitreal aflibercept in subjects previously treated with intravitreal anti-Vascular endothelial growth factor (VEGF) agents (ranibizumab or bevacizumab)
Currently, diabetic macular edema is treated is through injection of a medications such as off-label bevacizumab, which decreases the swelling in the retina. These injections are sometimes required monthly until the condition is controlled. Recently, there have been some new FDA approved treatments using laser that decrease the swelling. These approximately ten minute treatments do not require injections and don't cause permanent damage to the eye, and they may decrease the number of injections one needs to get to treat diabetic macular edema (DME). The purpose of this randomized clinical trial is to determine whether subvisible laser in combination with intravitreal bevacizumab is non-inferior compared to current standard of care (intravitreal bevacizumab alone) in achieving favorable outcomes for visual acuity, mean macular thickness, and patient quality of life, and has fewer needed intravitreal bevacizumab injections throughout the course of the 12 month study period.
The study hypothesis under test is that administration of the CCR2/5 antagonist has the potential to be as effective as the current treatment options for subjects with diabetic macular edema. The current treatment option for these subjects is an injection directly into the eye, while this CCR2/5 antagonist would be an oral drug which has the potential to be just as effective. This CCR2/5 antagonist also has a broader anti-inflammatory potential and might be able to provide an alternative mechanism to treat Diabetic Macular Edema.
To determine the safety and efficacy of intravitreal Aflibercept (Eylea) injection in patients with diabetic retinopathy in the prevention of macular edema following cataract surgery.
The purpose of this protocol is to determine whether point of care optical coherence tomography (OCT) imaging combined with an OCT-guided retinal referral algorithm at primary diabetes care visits increases rates of retina specialist eye care for patients with diabetic macular edema. The hypothesis is that OCT imaging with an automated OCT-guided referral algorithm will enable identification of patients at risk for vision loss from diabetic macular edema and facilitate direct referral to retina specialists for more timely evaluation and treatment.
Background: - Diabetic macular edema (DME) is a common condition in people with diabetes. DME occurs when blood vessels in the eye leak fluid, resulting in swelling inside the back of the eye and progressive vision loss. Research has shown that good blood sugar control can reduce the risk and severity of DME. However, not all diabetic patients with poor blood sugar control develop DME, and some patients develop DME despite excellent blood sugar control. This suggests that other factors, such as genes or inherited traits, may predispose or protect a diabetic patient from developing DME. Objectives: - To investigate genetic factors that may influence the development of diabetic macular edema. Eligibility: - Individuals at least 18 years of age who have type 2 diabetes, with or without diabetic macular edema. Design: * The study will require one visit to the National Institutes of Health eye clinic. * Participants will be screened with a medical history and basic eye examination. Individuals who have certain eye diseases other than DME may not be allowed to enroll in the study. * Participants will provide a blood sample, and will receive fluorescein angiography (an injection of fluorescein dye, after which a camera will take pictures of the dye as it flows through the blood vessels in the eye). * No treatment will be provided as part of this protocol.
