Active clinical trials for "Macular Edema"

The complicated schedules for administering topical steroid eye drops combined with forgetfulness and physical difficulties instilling the drops may compromise compliance; which in turn could increase the risk for secondary complications such as PME post-cataract surgery, especially in a high-risk diabetic population. Dextenza, a sustained- release steroid insert, could help preclude adherence difficulties and provide better bioavailability, being as effective as, or more effective than steroid drops in preventing PME. The aim of this study is to assess the incidence of PME in diabetic patients undergoing cataract surgery when comparing the Dextenza insert to topical prednisolone acetate 1% drops.

The purpose of the investigator's study is to evaluate the efficacy and safety profile of the pro re nata (PRN) regimen to 12 months by using intravitreal dexamethasone implant in eyes with treatment-naive diabetic macular edema patients.

Retinal vein occlusion (RVO) may lead to series of complications including retinal ischemia, macular edema (ME) and induce vision impairment. Intravitreal injection of Ranibizumab (0.5mg) has been proved to be a safe and effective method for the treatment of RVO-ME. In this study, different treatment regimens of Ranibizumab is applied and the effects is observed at 1-6 months to explore the best regimen for RVO. After 6 months, anti-VEGF therapy and/or laser photocoagulation is used to explore whether laser photocoagulation can maintain the therapeutic effect of Ranibizumab or reduce the injection number.

The purpose of this study is to evaluate in a prospective study the efficacy of intravitreal autologous plasmin enzyme in macular edema and to analyze the fibrinolytic system in vitreous body.

Diabetic macular edema is the most common cause of visual loss among patients with diabetic retinopathy. Pars plana vitrectomy has been reported to be effective for the treatment of diabetic macular edema. Previous report showed a limited improvement in visual acuity and macular thickness posterior intraoperative triamcinolone acetonide. Bevacizumab intravitreal injection has been proven be effective in the treatment of diabetic macular edema, in recent publications. The purpose of this study is to evaluate whether vitrectomy with and without intravitreal triamcinolone acetonide and bevacizumab injection affects vision outcome and macular thickness in patients with diabetic macular edema.

The purpose of this study is to compare the efficacy and safety of intravitreal injection of bevacizumab alone versus bevacizumab combined with triamcinolone for treatment of refractory diabetic macular edema.

Intravitreal triamcinolone acetonide is a well-known method of treatment of diabetic macular edema, however, it has many side effects, most commonly causing cataract and glaucoma. Suprachoroidal route is an emerging route of delivery of intraocular drugs. This is to our knowledge the first prospective study to compare the effect of triamcinolone acetonide delivered via the intravitreal versus the suprachoroidal route in the treatment of diabetic macular edema as regards safety and efficacy.

The study will explore the impact of photobiomodulation (PBM), pulsating at frequencies of red (660nm) and near-infrared (810nm)(NIR), concurrent with a ketogenic dietary protocol (serum ketones @ .5 - 2.0 mmol/L) to mediate vascular features of diabetic retinopathy (DR), diabetic macular edema (DME), age-related macular degeneration (AMD), mid-peripheral drusens, visual acuity and retinal disorders. Red and near-infrared light via light-emitting diode (LED) treatment promotes retinal healing and improves visual acuity by augmenting cellular energy metabolism, enhancing mitochondrial function, increasing cytochrome C oxidase activity, stimulating antioxidant protective pathways and promoting cell survival. LED therapy directly benefits neurons in the retina, the lateral geniculate nucleus and the visual cortex; likewise, a ketogenic dietary protocol shows metabolic and neuro-modulatory benefits within the CNS, most notably as treatment for refractory epilepsy. Photobiomodulation has been approved as a non-significant risk (NSR) modality for the treatment of eye disorders.

This study evaluates the effectiveness of intravitreal Aflibercept (IVA) injection therapy, combined with peripheral laser photocoagulation, in the treatment of macular edema caused by Leber's miliary aneurysm. We believe that our study makes a significant contribution to the literature because to our knowledge, it is the first to report cases, in which IVA injection therapy was used to treat this condition.

This study will evaluate the effects of add-on carotenoid plus anti-oxidant nutritional supplementation to standard anti-vascular endothelial growth factor therapy for subjects with center-involved diabetic macular edema
