CD160 represents a new angiogenic factor as its specific engagement by an agonist monoclonal antibody directed against human CD160 reduced angiogenesis of endothelial cells with a distinct mechanism from current angiogenic therapies that target the VEGF/VEGF-R pathway. A soluble form of CD160, sCD160, has been found to be highly expressed in the vitreous and the sera of patients with severe diabetic retinopathies, and can now be dosed with help of an ELISA test. The investigators aim to evaluate the association between ischaemic retinopathies (patients with or without) and sCD160 concentrations in the vitreous, the aqueous humour and the serum.
Branch retinal vein occlusion (BRVO) is often complicated by macular edema, possibly leading to severe visual loss or blindness. Treatment is repeated, intravitreal injections of vascular endothelial growth factor (VEGF)-inhibitors like aflibercept. The treatment is effective, but a need for repetitive injections is a concern for patients as well as society due to risk of side effects, regular hospital visits and the price of the drug. Former treatment included macular grid pattern photocoagulation, but this technology was limited by a poorer visual outcome for the patient and a higher risk of side effects, including central visual loss. A novel laser delivery system, called navigated laser photocoagulation, has proven effective, safe and precise, and has shown promising results in stabilising the effect of the VEGF-inhibitor treatment in similar diseases. Thus, in a 12-month prospective, randomized 1:1 study of 60 patients with BRVO and macular edema the investigators aim to (1) Examine the treatment response of patients treated with intravitreal aflibercept (Eylea®) and navigated retinal laser (Navilas®)(Group 1) as compared to patients treated with intravitreal aflibercept only (Group 2), and (2) Identify non-invasive retinal biomarkers (retinal oxygen saturation, macular ischemia and retinal vascular arteriolar and venular calibre) for successful treatment outcome.
To evaluate the efficacy and safety of Anti-VEGF instead of intraoperative fan-shaped photocoagulation in BRVO combined with vitreous hemorrhage.
Purpose: To evaluate retinal functional improvement by means of visual acuity and retinal sensibility examination after intravitreal dexamethasone implant in patients affected by cystoid macular edema secondary to retinal vein occlusion.
The difficulty to measure blood flow in humans is connected with the necessity of using not invasive, reliable and reproducible techniques. There is several quantitative approaches to study eye blood flow which do not answer all these specifications. The laser doppler velocimetry allows movement speed measures but not vessel diameter. Optical coherence tomography doppler allows a simultaneous diameter and speed of travel (movement) measures, but presents a limited spatial resolution and thereby not easily reproducible vessel diameter measures. The investigators propose development of a technique allowing a simultaneous diameter and velocity measure of these vessels.
Correlation between changes observed in OCT and VA in patients with retinal vein occlusion whether the patient's VA improves when macular edema improves in OCT or not ??
This phase Ib study investigates the safety and efficacy of performing a retinal vein cannulation with recombinant tissue Plasminogen Activator infusion into a retinal vein with the help of an updated dedicated surgical stabiliser for the treatment of central retinal vein occlusion.
The purpose of this study is to evaluate the efficacy and safety of the treat-and-extend regimen extending to 4 months by intervals of 4 weeks using intravitreal aflivercept injection for treatment of macular edema secondary to BRVO.
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.
