Diabetic Macular Edema Clinical Trials

This trial will assess the incidence of new and/or undiagnosed diabetic macular edema (DME) in diabetic patients that undergo a DME screening exam. The screening exam will consist of medical history, Electronic ETDRS visual acuity assessment, SD-OCT and color fundus photography

For the study arm receiving the VA-guided treatment regimen, the following retreatment criteria will be applied: if visual acuity remains stable ( 5 ETDRS letters) treatment intervals will be extended by 2 weeks as compared to the previous retreatment interval. if visual acuity decreases by more than 5 ETDRS letters ...

Study objective is to better understand the pathophysiology of diabetic macular edema (DME) by defining the factors that participate in the disease process or may be good biomarkers for disease progression. Study will investigate the temporal relationship between the course of treatment with anti-VEGF therapy and levels of candidate biomarkers ...

Within the province of Ontario, there are a limited number of retinal specialists for a large and geographically diverse population of 13.5 million people in 2012. Because the majority of these specialists are located in larger urban centers, many rural patients have difficulty travelling the significant distance from their communities ...

Intravitreal Ozurdex implant therapy improves visual outcome and OCT findings. The purpose of this study is that these results are correlated with the change of cytokine level known to be increased in DME patients.

Thirty eyes of diabetic patients with diabetic retinopathy with macular edema will be randomized using simple randomization method into two groups; A and B. Group A will undergo intravitreal injection of 500g Diclofenac, repeated monthly for 3 months. Electroretinogram will be performed before the injections, 4 weeks after first injection ...

Diabetic retinopathy patients who are at risk of developing macular edema (defined as 30 % increase from pre-operative baseline in central subfield macular thickness) within 90 days following cataract surgery. Diabetic patients are defined as those who have either Type 1 or Type 2 diabetes. The patients must have either ...

This study is an investigator initiated interventional study for subjects with diabetic macular edema that have been previously treated with bevacizumab or ranibizumab. Intravitreal aflibercept 2mg will be given until OCT (ocular coherence tomography) demonstrates an absence of fluid. Continued intravitreal aflibercept 2mg will then take place every 2 months ...

Patients who participate in this study will be selected among adults treated at the Retina Clinic and Ocular Oftalmologia clinics and will be aware of all stages of the research, formalizing the approval of their participation by informed consent term. The tests will be performed after pupillary dilation with 2 ...

Ocular perfusion pressure (ocular perfusion pressure - OPP), considered the driving force of ocular blood flow. Perfusion pressure is defined as the difference between the artery and vein blood pressure. Because ocular venous pressure is the same or slightly higher than the IOP (intra ocular pressure - IOP), it is ...
