Active clinical trials for "Macular Edema"

after advent of RD photoreceptor degeneration Occurred. This process appears as a incredible and progressive event that will not stop till reattachment of RPE and neurosensory retina happened . Process of degeneration begins from first hours of RD establishment Neuroprotection of photoreceptor following RD is a novel and debatable discussion encountered in recent years . How to stop this phenomena and neuroprotective agent role in this issue are a new interest of researches. In the study investigators are planning to perform a clinical trial to demonstrate the minocycline neuroprotective effect in a double blind design as this impact has been implicated previously in a animal study.

The aim of this study is to evaluate treatment effect and safety of navigation laser photocoagulation for mild diabetic macular edema compared with traditional laser.

Diabetic macular edema degeneration occur is a vision threatening condition. The investigators compare the efficacy of BEOVU and Eylea intravitreal treatment in the management

This pilot study aims to establish that treatment with near infrared light (NIR) reduces cystic macular oedema in patients with a retinal vein occlusion.

Background/aims: Aflibercept is an approved therapy for neovascular macular degeneration (AMD), diabetic macular edema (DME), retinal vein occlusion and other retinal conditions. Ziv-aflibercept is also approved by FDA and is extremely cost-effective relative to the expensive same molecule aflibercept. In vitro and in vivo studies did not detect toxicity to the retinal pigment epithelium cells using the approved cancer protein, ziv-aflibercept. Ziv-aflibercept had no loss of anti-VEGF activity when kept at 4°C in polycarbonate syringes over 4 weeks. Similar to bevacizumab, compounded ziv-aflibercept would yield a tremendous saving compared to aflibercept or ranibizumab. Phase I studies and case reports did not report any untoward toxic effects but attested to the clinical efficacy of the medication. Our purpose is to ascertain the long-term safety and efficacy in various retinal diseases of intravitreal ziv-aflibercept. Methods: Prospectively, consecutive patients with retinal disease that require aflibercept (AMD, DME, RVO, and others) will undergo instead the same molecule ziv-aflibercept intravitreal injection of 0.05 ml of fresh filtered ziv-aflibercept (1.25mg). Monitoring of best-corrected visual acuity, intraocular inflammation, cataract progression, and retinal structure by spectral domain OCT to be done initially, one month, 6 months, 1 year, and 2 years after injections. Anticipated Results: Analyze signs of retinal toxicity, intraocular inflammation, or change in lens status, together with best corrected visual acuity and central foveal thickness at 1 month, 6 months, 1 year and 2 year. Anticipated Conclusions: Off label use of ziv-aflibercept improves visual acuity without ocular toxicity and offers a cheaper alternative to the same molecule aflibercept (or lucentis), especially in the third world similar to bevacizumab.

Diabetic macular edema refers to swelling (fluid accumulation) in the center of the retina. The retina is like the film of a camera and is located in the back of the eye. This condition can develop in diabetics where swelling results from leaking of fluid from the blood vessels of the eye, into the center of the retina, the macula. If left untreated, this can affect central. The current standard treatment for diabetic macular edema includes medications injected directly into the eye (intravitreal injections) and laser eye treatment. The drugs that are injected directly into the eye are known as anti-VEGF agents which help to reduce the leaking. This includes bevacizumab (Avastin®) and ranibizumab (Lucentis®). However, some patients do not respond well to these anti-VEGF treatments and will be given the option of switching to an another newer anti-VEGF medication, called aflibercept (Eylea®) that is approved to treat DME. A recent large study has demonstrated that aflibercept was as efficacious as other anti-VEGF therapies listed above and was even superior in patients with worse vision (Diabetic Retinopathy Clinical Research Network, Wells JA, Glassman AR, et al. Aflibercept, Bevacizumab, or Ranibizumab for Diabetic Macular Edema. N Engl J Med. 2015:150218140025008-150218140025008). The purpose of this study is to determine what factors affect the treatment response to aflibercept (amount of swelling reduction) for patients with diabetic macular edema, who were previously unresponsive to ranibizumab injections.

This study will examine potential factors in the aqueous humor that may contribute to the development or progression of macular edema or fibrosis (due to any underlying disease) in patients suffering from these conditions.

A Single Arm, Single Dose Study to Evaluate the Effect of intravitreal dexamethasone implant (Ozurdex®) on hard exudates of diabetic macular edema.

Objectives: To compare the efficacy of monotherapy with anti-Vascular Endothelial Growth Factor (ranibizumab or bevacizumab) with combined therapy with anti-Vascular Endothelial Growth Factor and end-point-management grid laser photocoagulation for diabetic macular edema. Study design: Open-label non-randomized interventional study. Study overview: This study aims to look at the efficacy of treating diabetic macular edema (DME) with either anti-Vascular Endothelial Growth Factor(anti-VEGF) monotherapy, compared with combination therapy with anti-VEGF and End-Point-Management (EPM) grid laser photocoagulation, over a period of 6 months. Various sites from across Asia (Japan, South Korea, Hong Kong) will participate. Depending on the availability of EPM laser, sites can either contribute to the 'Anti-VEGF monotherapy' arm, or to the 'Combination therapy' arm.

This study is aimed to compare the effect of combined intravitreal Bevacizumab and Fasudil injection with Bevacizumab only injection in patients with persistant macular edema secondary to ratinal vein occlusion. Methods: In this study patients with retinal vein occlusion patient who had at least three or more intravitreal AntiVEGF injection with persistence of macular edema at funduscopic examination is recruited. The eligible patients in randomized in two groups "Bevacizumab" and "Bavacizumab + Fasudil" and in injected intravitreally for 3 times monthly. In "Bevacizumab+Fasudil" group patients receive two injections at each session Bavacizumab and Fasudil. In "Bevacizumab" group patients receive only Bevacizumab. The patients are followed for 6 months and central macular thickness and visual acuity is measured at baseline and monthly for 6 month. Baseline ancillary exams include Fluorescein Angiography and OCT-Angiography which is performed at the final exam as well. Patients needing any therapeutic intervention is addressed during the 6 month follow up period.
