Macular Edema

Researchers are looking for new ways to treat diabetic macular edema (DME). In this trial, researchers want to learn if a trial medicine called MK-8748 can treat DME. An available standard (usual) treatment for DME is aflibercept. However, standard treatments such as aflibercept may not work for every person. The main goal of this trial is to learn if MK-8748 works as well as aflibercept to treat DME.

Silicone oil is commonly used as a temporary intraocular tamponade to support the retina during vitreoretinal surgery for complex retinal detachment and other severe retinal conditions. Although removing silicone oil typically leads to visual improvement, the degree of visual recovery varies widely among patients. Optical coherence tomography (OCT) is a non-invasive imaging technique that provides detailed cross-sectional views of the macula, the central portion of the retina responsible for detailed vision. The primary aim of this observational study is to evaluate the relationship between specific macular OCT biomarkers (such as central macular thickness, ellipsoid zone integrity, and macular edema) measured before silicone oil removal and visual outcomes after surgery. Identifying these structural features may help ophthalmologists better predict visual recovery and counsel patients prior to surgery. Participants will undergo a standard comprehensive ophthalmic examination, best-corrected visual acuity (BCVA) testing, and a macular OCT scan prior to their scheduled silicone oil removal. Visual acuity will then be reassessed during a standard postoperative follow-up visit at least 1 month after surgery. Participation is observational and does not alter routine surgical or medical management.

This study is open to adults 18 and older with an eye condition called diabetic macular edema. People are required to have a specific type of diabetic macular edema called centre-involved diabetic macular edema (CI-DME) to take part. The purpose of this study is to find out whether a medicine called BI 1815368 improves sight in people with CI-DME and to find the most suitable dose. This study has 2 parts. In the first part, participants are put into 2 groups of equal size randomly, which means by chance. One group takes BI 1815368 tablets and the other group takes placebo tablets. Placebo tablets look like BI 1815368 tablets but do not contain any medicine. In the second part, participants are put into 4 groups of equal size randomly. 3 groups take different daily doses of the study medicine, BI 1815368, while 1 group takes placebo. All participants take tablets twice a day for about 11 months. Participants are in the study for about 1 year. During this time, they visit the study site 16 times. At visits, doctors check the participant's vision and collect information on any health problems. They take detailed pictures of the eye. The changes over time are compared between the groups to see if the treatment works.

This is a multi-center, open label study to assess the safety, tolerability, and efficacy of KIO-104 administered by IVT injection to the study eye of eligible participants with macular edema.

Knowledge of the pathogenesis of ocular conditions, a leading cause of blindness, has benefited greatly from recent advances in ophthalmic imaging. However, current clinical imaging systems are limited in resolution, speed, or access to certain structures of the eye. The use of a high-resolution imaging system improves the resolution of ophthalmoscopes by several orders of magnitude, allowing the visualization of many microstructures of the eye: photoreceptors, vessels, nerve bundles in the retina, cells and nerves in the cornea. The use of a high-speed acquisition imaging system makes it possible to detect functional measurements such as the speed of blood flow. The combination of data from multiple imaging systems to obtain multimodal information is of great importance for improving the understanding of structural changes in the eye during a disease. The purpose of this project is to observe structures that are not detectable with routinely used systems.

This is an open label dose-escalation study to evaluate the safety and treatment benefits of MS-553 in treatment-naive diabetic retinopathy patients with central involved macular edema. Fifteen subjects with diabetic macular edema will be enrolled into each of three dose cohorts and will receive oral administration of MS-553 for 8 weeks.

The purpose of this study is to investigate whether subthreshold treatment with micropulsed laser can be effective in resolving macular edema in patients with inherited retinal dystrophy. Visits will be performed after 1, 3, 6, 9, 12, 18, and 24 months after treatment. Laser treatment will be performed on the day of the first visit, and its repetition at subsequent visits between months 3 and 12 will be evaluated. Evaluations of treatment effects will include: * comprehensive ophthalmologic examination * multifocal electroretinogram * OCT examination * OCT-angiography examination * retinography Primary endpoint. \- central retinal thickness, measured by OCT

Intravitreal dyes are intended to make the surgical extraction of the Internal limiting membrane (ILM) safer and more complete. However, the search for an adequate vitaly dye is ongoing. The most commonly used vital dye is Indocyanine green (ICG), although it is not approved for intravitreal use and has been associated with ocular toxicity. The reason for its continued popularity seems to be that it stains the ILM better than the approved and less toxic alternative substances Brilliant Blue G (BBG) and Trypan blue (TB). According to anecdotal reports from surgeons, another reason for ICGs popularity may be the fact that it seems to make ILM removal easier. Ultimately, the intention of the investigators research is to identify possible modifications to existing dyes to reach improved intraoperative dye utility combined with a favorable safety profile. Protocol was amended and approved concerning additional use of basal membrane of deceased donors.

The purpose of this study is to evaluate the effectiveness of adding curcumin oral treatment to bevacizumab intravitreal injection in patients with central macular edema. A blind study and a randomized and controlled clinical trial are conducted on diabetic patients with macular edema. The patients are divided into two intervention groups (bevacizumab + curcumin) and control (bevacizumab + placebo). The evaluation of the central thickness of the macula and the evaluation of the central volume of the macula are the primary goals and the evaluation of the best visual acuity of the patient is the secondary goal.
