Filter by:This is a feasibility study to assess the use of wide field adaptive optics optical coherence tomography (WF-AO-OCT) to determine whether there are structural differences in the peripheral retina in participants diagnosed with diabetic retinopathy compared to a healthy control group. This study being conducted under an abbreviated IDE. The investigators will analyze data using descriptive statistics. Risks related to light exposure will be managed by ensuring that the exposure to the WF-AO-OCT light source is well below maximum permissible limits for safe exposure.
This is a 24-week, prospective, multi-center, open-label, randomized, investigator-initiated pilot study to explore the effects of RBZ (0.5 mg) plus DEX implant (0.7 mg) PRN combination therapy (n = 30) vs. DEX implant PRN monotherapy (n = 30) in pseudophakic eyes with center-involved DME that have demonstrated prior incomplete response to 3-6 anti-VEGF treatments.
The objective of this study is to image retinal vascular alterations in patients with retinal disease using the AngioVue OCT-A system and understand the information these images provide. The investigators will image study participants who have retinal diseases with the AngioVue unit (Optovue) and will collect relevant clinical data to understand the nature of the information contained in images obtained on AngioVue. This study being conducted under an abbreviated IDE. The investigators will analyze data using descriptive statistics. Risks related to light exposure will be managed by ensuring that the exposure to the AngioVue light source is well below maximum permissible limits for safe exposure.
Currently medications injected intravitreally in previously vitrectomized eyes have a very short half-life due to enhanced clearance of the drug. The use of the Ozurdex (dexamethasone) implant may allow sustained levels of steroid delivery to patients with diabetic macular edema that have undergone prior vitrectomy. The sustained steroid levels may lead to improved central retinal thickness measurements and improved visual acuity.
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.
Purpose: to evaluate the effect of intravitreal injection of tissue plasminogen activator(tPA) in treatment of refractory diabetic macular edema(DME).
The purpose of this study is to assess the safety and tolerability of MP0112 (a novel, potentially long acting VEGF inhibitor) in patients with diabetic retinal edema.
It is well known that blindness is one of the most feared disabilities expressed by patients in the United States. Estimates of the economic impact of visual disability in the current population exceed 30 million US dollars in this country alone. The reasons for this figure are many; however age related macular degeneration (ARMD), diabetic retinopathy, glaucoma and uveitis are responsible for the majority of permanent visual disability and hence the costs in both quality of life and placing an economic burden on society. Research that may help reverse various abnormal biological responses that lead to or worsen clinical manifestations of diabetic retinopathy would be valuable.
To assess the efficacy of oral aliskiren as a therapy for diabetic macular edema
The purpose of this study is to determine if treatment with infliximab improves macular edema which is refractory to laser photocoagulation in patients with diabetes.
