Active clinical trials for "Macular Edema"

Purpose: Study the effect of nepafenac ophthalmic suspension 0.1% to prevent post-operative cystoid macular edema following uncomplicated cataract surgery Participants: Patients having cataract surgery at UNC who meet eligibility criteria Procedures (methods): Patients will have pre and post-operative vision measured and optical coherence tomography (OCT) testing, also cataract density and intraoperative phacoemulsification parameters including ultrasound power and ultrasound time will be measured. Patients will be randomized into two groups. Group 1 will be treated with standard post-operative cataract management. Group 2 will be treated with standard post-operative cataract management plus topical nepafenac for one month. Post-operative macular thickness will be studied by analyzing the visual acuity and OCT measurements at two months post surgery.

Goals of the study are to evaluate how peri-operative versus intra-operative anti-VEGF intravitreous injections affect visual acuity (BCVA) in patients with persistent diabetic macular edema who are undergoing cataract surgery; and to evaluate how peri-operative versus intra-operative anti-VEGF intravitreous injections affect OCT CSF thickness and total number of postoperative injections in patients with diabetic macular edema who are undergoing cataract surgery.

In this study, measurements of central macular thickness using optical coherence tomography along with examination of visual acuity by Snellen's chart in diabetic hypertensive patients will be done .

For patients with at least one eye with non-tractional diabetic edema refractory to 6 months of anti-VEGF injections (anti Vascular endothelial growth factor injections), a randomization is done: one group of patients will receive the standard treatment (anti-VEGF injections, switch to another anti-VEGF drug, additional photocoagulation or any other treatment except vitrectomy during the first 6 months after the randomisation) and the other group of patients will receive vitrectomy (with only additional photocoagulation during the first 6 months, then any treatment from 6 months after the randomization).

This trial investigated whether adding Iluvien sustained release steroid intravitreal eye implant at the beginning of regular anti-VEGF (anti Vascular Endothelial Growth Factor) intravitreal eye injection treatment for diabetic macular oedema would improve disease stability and reduce the need for regular anti-VEGF intravitreal eye injections over first two years. Diabetic macular oedema, accumulation of microscopic fluid at the back of the eye, is a major cause of poor vision in patients with diabetes. This is a double mask randomized control multisite trial, to be conducted at 10 NHS hospital eye clinics in England.

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.

Treatment with Ranibizumab of the residual diabetic edema in patients with failed response to Bevacizumab.

Diabetic retinopathy (DR) is the microvascular complication in the eye due to uncontrolled diabetes. According to the International Diabetes Federation (IDF), 382 million people had diabetes in 2013 and this number is expected to rise to 592 million by 2035, while 175 million people remain undiagnosed. Ninety percent of these people suffer from type 2 Diabetes mellitus(DM). Over time, patients with non-proliferative DR may progress to more advance stages of DR, with increased risk of vision threatening conditions such as diabetic macular edema (DME). DME is the most frequent cause of vision loss in patients with diabetes and eventually can lead to blindness. The management strategy is crucial to prevent or limit the progression of DR. Patient education creates an important tool to control diabetes, to prevent complications and to reduce the cost. Several studies point out that diabetes group education, compared with individual education, was equally effective at improving diabetes control. Another group based education for type 2 DM shown effective in improving HbA1c, knowledge of diabetes, reduction of systolic blood pressure, body weight and requirement for diabetes medication. Studies have showed that group education had significant changes compared with individual education in HbA1c in 6 and 12, months and significant changes were found in fasting blood glucose in 12 months, diabetes knowledge, and self-management skills. Moreover, a study supported that, compared with individual counselling, group self-management education was associated with fewer acute complications and some improvements in the care process. There is no adequate evidence of which educations methods are the most effective in improving clinical outcomes of people with type 2 diabetes. There was a lack in diabetes management in India regarding the multidisciplinary diabetic intervention tool. Thus the investigator's aim is to focus on interventions to improve the compliance, knowledge/awareness about diabetes, physical activity, diet plan and attendance for diabetic check-up which got emerged from a qualitative study. There is a need to monitor the diabetic patients closely to ensure the compliance towards intervention given at home.

Comparable data for bevacizumab and aflibercept are lacking, as are studies comparing the systemic levels of ranibizumab, bevacizumab, and aflibercept and their relative effects on circulating vascular endothelial growth factor. In the present prospective study, the investigators evaluated serum drug levels and plasma free vascular endothelial growth factor (VEGF) levels in patients with neovascular age-related macular degeneration following intravitreal injections of ranibizumab, bevacizumab and aflibercept.

Diabetic macular oedema (DMO) is a sight-threatening problem for diabetic patient who has swelling in macula. Patients with DMO can receive laser treatment and achieve good acuity finally. However, some patients still have difficulties in reading even after proper treatment. In this project, the investigators aimed to explore the effectiveness of different training paradigms in improving reading performance in patients with DMO.
