The purpose of this study is to compare the amount of intraoperative intraocular bleeding during 23-gauge pars plana vitrectomy (PPV) for diabetic traction retinal detachment (TRD) with and without preoperative intravitreal bevacizumab treatment.
Proliferative diabetic retinopathy patients requiring pars plana vitrectomy receiving preoperative 0.625 mg intravitreal bevacizumab 3-10 days prior to vitrectomy will have similar surgery times and similar intra-operative and postoperative complications to subjects who receive preoperative 1.25 mg intravitreal bevacizumab at both 3-5 days, and 6-10 days prior to vitrectomy.
Purpose: Determine the short-term safety of intravitreal bevacizumab by multifocal electroretinography (mf-ERG). Methods: 120 eyes with choroidal neovascularization, proliferative diabetic retinopathy and retinal vein occlusion received intravitreal bevacizumab (2.5mg/0.1cc). All patients underwent best corrected visual acuity, fluorescein angiography, optical coherent tomography and mf-ERG before and 1 month after treatment.
Certain percent of the eyes with proliferative diabetic retinopathymay require pars plana vitrectomy (PPV) due to vitreous haemorrhage, proliferative membrane, and tractional retinal detachment. This study will compare intravitreal injection of anti-vascular endothelial growth factor (ranibizumab) versus sham injection before vitrectomy for PDR. The main focus is to see if pre-operative injection of ranibizuman can reduce peri-operative hemorrahge related complications.
Patients are required to position prior to retinal detachment surgery. We seek to see whether there is a correlation between the performed positioning and retinal detachment progression/regression in fovea-on retinal detachment patients.
Recently, intravitreal bevacizumab (Avastin) injection has gained popularity as a potential treatment of intraocular neovascularization (CNV) associated with age related macular degeneration and diabetic retinopathy. The efficacy of the drug is thought to be related with its pharmacologic blockade of VEGF. The purpose of this study is to determine the effect of the intravitreal bevacizumab on the fibrovascular membrane associated with proliferative diabetic retinopathy by obje...
To investigate the feasibility and advantages of using pressurized perfluorocarbon liquid (PCL) perfusion to remove vitreous during suction-cutting 23 GA vitrectomy using a dual, dynamic drive (3D)technology, in complicated retinal detachment surgeries.
This study investigates the effectiveness of a simple treatment to prevent proliferative vitreoretinopathy (PVR). Intraoperative intravitreal 5-fluorouracil (5-FU) and low molecular weight heparin (LMWH) is used as a prophylactic therapy in high-risk patients with primary rhegmatogenous retinal detachment (RRD). Our major motivation is to reduce the incidence of PVR in the group that receives the trial drug.
Background: to evaluate the 3-month efficacy of a single dose of intravitreal bevacizumab on the progression of severe non proliferative diabetic retinopathy, proliferative diabetic retinopathy and active photocoagulated diabetic proliferative by evaluation of ischemic areas and regression of retinal and disc neovasculrization. Methods: 40 patients were enrolled in a prospective, interventional study. Patients were treated with intravitreal bevacizumab 0.1ml (0.25mg). We evalu...
The aim of this study is to report outcomes of pars plana vitrectomy (PPV) in pediatric retinal detachment (RD) accompanied with proliferative vitreoretinopathy (PVR) as well as complications and factors influencing the final anatomical and functional results. This is retrospective consecutive case series of 14 eyes treated with primary PPV for RD repair. Average postoperative follow-up period is 34 months.
Treatment of severe proliferative diabetic retinopathy (PDR) may require the use of silicone oil for long-term retinal tamponade to prevent recurrent retinal detachment. Massive bleeding during surgery before proper release of traction and peri-silicone oil proliferation after surgery were major causes of surgical failure. The likelihood of reproliferation rises in the presence of significant preretinal blood. It is therefore crucial to reduce intraoperative and postoperative p...
The purpose of this trial is to access the tolerability of INS37217 Intravitreal Injection when administered intravitreally in subjects with macula-on or macula-off rhegmatogenous retinal detachment (RRD).
The purpose of this study is to examine and compare, prospectively, best corrected visual acuity (BCVA) outcomes and complications of a cohort of patients with Proliferative Diabetic Retinopathy and Tractional Retinal Detachment not involving macula undergoing pars plana vitrectomy (PPV) or conventional management (panretinal photocoagulation).
Purpose: To evaluate the logical surgical approaches in closing macular holes in eyes of proliferative diabetic retinopathy with retinal detachment
Postoperative vitreous hemorrhage is a common complication after vitrectomy for proliferative diabetic retinopathy. There have been efforts to lower the incidence of postoperative vitreous hemorrhage such as preoperative bevacizumab injection. Bevacizumab (Avastin) is a potent inhibitor of angiogenesis and has been shown to decrease retinal and iris neovascularization in proliferative diabetic retinopathy. Recently there have been reports showing that preoperative bevacizumab i...
Central serous chorioretinopathy (CSC) has been known since it was first described by Von Graefe and termed “idiopathic detachment of the macula” in 1866, is a well-characterized disorder leading to serous neurosensory elevation of the central macula. The acute form of the disease is associated with focal leakage at the level of the retinal pigment epithelium (RPE) demonstrated with fluorescein angiography (FA). The disorder is self-limited in the majority of patients, who ...
The purpose of this study is to evaluate the role, the safety and the effectiveness of Intravitreal Bevacizumab injections as an adjunct to vitrectomy in the management of severe proliferative diabetic retinopathy.
To evaluate the efficacy of sequential therapy with intravitreal dexamethasone implant followed by bevacizumab compared with bevacizumab monotherapy for macular edema (ME) secondary to retinal vein occlusion (RVO).
The purpose of this study is to demonstrate the efficacy of ranibizumab in patients with retinal pigment epithelial detachment secondary to age-related macular degeneration (AMD).
Retinal detachments correspond to a separation of the neuroepithelium from the pigment epithelium. They can be exudative (sometimes in conjunction with a tumor), tractional, traumatic (postoperative) or rhegmatogenous (in relation to a tear). Ultrasound, requested when the fundus is difficult to achieve and shows a hyperechoic mobile membrane. It can also measure the hemodynamic parameters of retinal arteries. A preliminary study showed a correlation between systolic velocity...
The RECOVERY trial will assess the safety and tolerability of 2 mg intravitreal aflibercept injections (IAI) given monthly (Q4WK) or every 12 weeks (Q12WK) for the treatment of retinal non-perfusion (RNP) associated with proliferative diabetic retinopathy (PDR) primarily assessed through retinal capillary non-perfusion.
Persistent or recurrent vitreous hemorrhage after vitrectomy for diabetic retinopathy complications is a common occurrence with an incidence of 12% to 63%. This complication may prolong vitreous clear-up and delay visual rehabilitation significantly, and sometimes requires additional procedures or surgery. The causes of bleeding are diverse. Evidence suggests fibrovascular proliferation from the sclerotomy sites or from the vitreous base may be an important source of recurrent...
This clinical trial will test the efficacy and safety of oral colchicine in prevention of proliferative vitreoretinopathy (PVR) in cases of rhegmatogenous retinal detachment
Bevacizumab is an anti-VEGF agent used in approved for use in metastatic colorectal carcinoma (FDA Approved). This study analyzes the safety and efficacy of off-label Intravitreal Injection of bevacizumab (Avastin) for CNVM, Macular oedema due to diabetic retinopathy, vascular occlusion and other retinal disorders.
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 "Bevac...
