Active clinical trials for "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.

The purpose of this non interventional retrospective study is to continue to collect data from patients following their completion of Protocol CLS 1003-201: "Safety and Efficacy of Suprachoroidal CLS-TA with Intravitreal Aflibercept in Subjects with Macular Edema Following Retinal Vein Occlusion" (ie, the parent study).

Retinopathy of prematurity (ROP) is a disorder of development of the neural retina and its vasculature that may impact vision in vulnerable preterm neonates for a lifetime. This study utilizes new technology to determine visual and neurological development of very preterm infants in the intensive care nursery, during a period of rapid growth of the retina, optic nerve and brain. The long-term goal of this study is to help improve preterm infant health care via objective bedside imaging and analysis that characterizes early critical indicators of poor vision, neurological development and ROP, which will rapidly translate to better early intervention and improved future vision care.

More than 29 million people in the US are living with diabetes, many of whom will develop diabetic retinopathy (DR) or diabetic macular edema (DME) collectively known as diabetic eye disease (DED), the leading cause of vision loss and blindness in working-age adults. Annual eye screening is recommended for all diabetic patients since vision loss can be prevented with laser photocoagulation and anti-VEGF treatment if DR is diagnosed in its early stages. Currently, the number of clinical personnel trained for DR screening is orders of magnitude smaller than that needed to screen the large, growing diabetic population. Therefore, to meet this large unmet need for DR screening, a fully-automated computerized DR screening system is necessary. EyeArt is an automated screening device designed automatically analyze color fundus photographs of diabetic patients to identify patients with referable or vision threatening DED. This study is designed to assess the safety and efficacy of EyeArt.

The objectives of this study are to investigate the safety and effectiveness of EYLEA

Purpose: To evaluate the effect of intravitreal triamcinolone acetonide (IVTA) on uveitis-associated cystoid macular edema (CME) using high resolution optical coherence tomography (SDOCT) in conjunction with thorough visual function testing. Methods: 28 patients with uveitis-associated CME were examined before intravitreal triamcinolone injection (IVTA) (v1) and at day 1 (v2), week 1 (v3) and month 1 (v4) after injection. Retinal anatomy was evaluated using Cirrus HD-OCT (Carl Zeiss Meditec). Visual function testing consisted of assessing ETDRS distance visual acuity (VA), reading acuity and reading speed using a standardized German-language test (Radner Reading charts), contrast sensitivity using Pelli-Robson Contrast Sensitivity charts and fundus-controlled microperimetry using the MP-1 Microperimeter (Nidek). Here we utilized a cartesian grid consisting of a central locus and three concentric box-shaped stimulation areas. The changes of retinal anatomy over time were compared to the respective outcome of visual function.

The purpose of this study is to measure biomarkers in the vitreous of patients undergoing Lucentis or avastin treatment.

The study objective is to determine the course of changes in OCT measured macular thickness and visual acuity following a single session of focal photocoagulation for center-involved DME. The response will be evaluated separately in eyes with and without prior focal photocoagulation for DME. The purpose is to determine the proportion of eyes that continue to improve at least 5 letters in visual acuity or at least 10% in central retinal thickness after a session of focal photocoagulation. In addition, the study will explore whether any baseline factors can be identified that are predictive of the response. All subjects will have follow-up visits 8 weeks and 16 weeks post treatment. At the 16-week visit, study eyes are evaluated for change in retinal thickness and visual acuity from baseline. Treatment is to be deferred and follow up continued if visual acuity letter score has improved by >5 or OCT central subfield thickness has decreased by >10% compared with baseline. If visual acuity letter score has not improved by at least 5 and OCT central subfield thickness has not decreased by at least 10%, then the eye is classified as 'not improved' and the investigator may provide additional treatment. Follow up ends for eyes that receive additional treatment at this visit. However, if the investigator and participant elect to defer additional treatment (even if deferral criteria are not met), then follow up will continue until the study eye receives additional treatment for DME. Eyes continuing in follow up have visits every 8 weeks (+1week) as long as there has been continued improvement in visual acuity (letter score improved >5 ) or retinal thickness (central subfield thickness decreased by >10%) compared with the visit 16 weeks earlier. The longest follow-up time will be 48 weeks. By providing information on the length of time during which clinically meaningful improvement occurs following focal photocoagulation, clinicians will be better able to determine when further photocoagulation or other treatments should be considered for persistent DME. Depending on the results of this study, a future randomized clinical trial will be considered comparing the more aggressive retreatment photocoagulation regimen currently serving as the standard DRCR Network approach to focal photocoagulation for macular edema with the less aggressive regimen evaluated in this protocol.

To describe the use of intravitreal aflibercept in routine clinical practice and to describe follow-up as well as treatment patterns in patients with wAMD or DME in routine clinical practice in Canada for a study population of treatment naive patients and those who have received prior therapy (anti-VEGF injections, laser, steroids, etc).

To evaluate the impact of telemedicine system in rural hospitals for diagnosis and treatment of Diabetes retinopathy and Diabetes macular edema.
