This study will evaluate the effects of a novel multi-component dietary supplement on the visual function and retinal structure of patients with diabetes with both no diabetic retinopathy and mild to moderate diabetic retinopathy. This is a placebo-controlled trial and neither subjects nor examiners will know if any given subject is taking active supplement or placebo. The hypothesis is that the supplement will improve visual function and retinal structure in subjects on active supplement
The purpose of this study is to test the efficacy of an 0.7 mg intravitreal dexamethasone implant (Ozurdex®) on macular leakage and visual acuity for patients with recalcitrant diabetic macular edema.
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.
This study will evaluate the safety and efficacy of OTT166 Ophthalmic solution in participants with Diabetic Retinopathy.
This randomized trial will evaluate the effect of fenofibrate compared with placebo for prevention of diabetic retinopathy (DR) worsening through 6 years of follow-up in eyes with mild to moderately severe non-proliferative DR (NPDR) and no CI-DME at baseline. In addition to evaluating efficacy, this study aims to evaluate the feasibility of a model for ophthalmologists to prescribe or collaborate with a primary care provider such as an internist/endocrinologist to prescribe and monitor the drug safely. If this study demonstrates that fenofibrate is effective for reducing the onset of proliferative diabetic retinopathy (PDR) or and the results are adopted by the community of retina specialists, a new strategy to prevent vision threatening complications of diabetes could be widely adopted. Widespread use of an oral agent effective at reducing worsening of DR would decrease the numbers of patients who undergo more invasive and much more expensive treatment for DR and who are consequently at risk for side effects that adversely affect visual function. This study will also assess the relationship of glycemic variability, as measured by continuous glucose monitoring with DR outcomes. Ancillary studies will characterize functional and structural outcomes in this cohort.
This study is a Phase I/II, multicenter, randomized, study of the efficacy and safety of ranibizumab injection monotherapy verses a duel therapy of 0.3mg ranibizumab combined with ultra wide, 200° field angiography guided pan retinal photocoagulation in patients with CSME-CI secondary to diabetes mellitus (Type 1 or 2).

Multiple studies have implicated vascular endothelial growth factor VEGF as a major causative factor in human eye diseases characterized by neovascularization including proliferative diabetic retinopathy (PDR) and vascular permeability including diabetic macular edema (DME). While there is strong evidence that PDR outcomes are markedly reduced in eyes that are treated with monthly anti-VEGF therapy (A Study of Ranibizumab Injection in Subjects With Clinically Significant Macular Edema (ME) With Center Involvement Secondary to Diabetes Mellitus: RIDE/RISE) and moderately reduced in eyes that received fairly frequent dosing during the 1st year of treatment (Diabetic Retinopathy Clinical Research Network protocol I), it is unknown whether or not an earlier but less frequent dosing regimen would result in similar, favorable anatomic outcomes, and whether favorable anatomic outcomes subsequently would result in favorable visual acuity outcomes. If this study demonstrates that intravitreous aflibercept treatment is effective and safe for reducing the onset of PDR or center involved- DME (CI-DME) in eyes that are at high risk for these complications, a new strategy to prevent vision threatening complications of diabetes will be available for patients. The application of intravitreous aflibercept earlier in the course of disease (i.e., at the time when an eye has baseline severe non-proliferative diabetic retinopathy) could help to reduce future potential treatment burden in patients, at the same time resulting in similar or better long-term visual outcomes, if PDR and DME are prevented. The primary objectives of this protocol are to 1) determine the efficacy and safety of intravitreous aflibercept injections versus sham injections (observation) for prevention of PDR or CI-DME in eyes at high risk for development of these complications and 2) compare long-term visual outcomes in eyes that receive anti-VEGF therapy early in the course of disease with those that are observed initially, and treated only if high-risk PDR or CI-DME with vision loss develops. Secondary objectives include: * Comparing other visual acuity outcomes between treatment groups, such as proportion of eyes with at least 10 or at least 15 letter loss from baseline, or gain or loss of at least 5 letters at the consecutive study visit just before and at the 2- or 4-year visit * Comparing optical coherence tomography (OCT) outcomes, such as mean change in OCT central subfield thickness and volume from baseline * Comparing proportion of eyes with at least 2 and 3-step worsening or improvement of diabetic retinopathy severity level (scale for individual eyes) by central reading center from baseline * Comparing associated treatment and follow-up exam costs between treatment groups * Comparing safety outcomes between treatment groups
