Filter by:With the increasing incidence of proliferative diabetic retinopathy (PDR), subsequent neovascular glaucoma (NVG) has become one of the main causes of blindness in PDR patients, and the intraocular pressure of PDR patients with NVG is often stubborn. For these patients, not only is the effect of drugs in lowering intraocular pressure poor, but the results of surgery are often unsatisfactory. Because of its poor prognosis, clinical research for better strategy is of great significance in the current situation. At present, for such patients, a combination of effective control of intraocular pressure and treatment of the primary disease is often used. The purpose of this study was to investigate the clinical effects of preoperative with/without intraoperative anti-vascular endothelial growth factor (VEGF) drug therapy combined with pars plana vitrectomy (PPV), pan-retinal photocoagulation (PRP), and pressure-reducing valve implantation in patients with NVG secondary to PDR. Furthermore, the changes of neurotrophic factors in the vitreous humor before and after anti-VEGF treatment will be explored.
Purpose: To investigate intravitreal aflibercept (IVA) injection as an adjunctive treatment to trabeculectomy with mitomycin C (TMC) and panretinal photocoagulation (PRP) for neovascular glaucoma (NVG). Setting: Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand Study design: Prospective interventional case series Methods: PRP and IVA (2 mg/0.05 ml) injection were given, and TMC was performed within 2 weeks after IVA. Additional PRP, laser suture lysis, subconjunctival 5-fluorouracil injection, and bleb needling were performed after TMC if indicated. Best-collected visual acuity (BCVA), intraocular pressure (IOP), surgical complications, and number of anti-glaucoma medications were collected.
The neovascular glaucoma (NVG) is a refractory type of secondary glaucoma and often lead to frustrated treatment and blindness. It has been confirmed high levels of vascular endothelial growth factor (VEGF) in NVG. Conbercept is an anti-VEGF agent，its role in regression of other neovascular disorders such as wet-type age-related macular degeneration and diabetic retinopathy has been described. Investigators aim to evaluate the efficacy and safety of intracameral and intravitreal injection of conbercept for the treatment of NVG.
This study will determine the effectiveness of Mitomycin-C use in the glaucoma surgery Ahmed valve implantation. Approximately 100 patients will be enrolled, with half receiving the Mitomycin-C treatment and the other half receiving placebo treatment.
This 52 week study will assess the use of intravitreal aflibercept injections in patients with neovascular glaucoma (NVG) compared to standard of care panretinal photocoagulation. The investigators hypothesize that the neovascularization of the iris and angle present in neovascular glaucoma will resolve more quickly in eye treated with intravitreal aflibercept injection alone and result in increased comfort and preservation of visual field as compared to current standard of care utilizing pan-retinal photocoagulation. The advantages to intravitreal aflibercept injection use could include resolution of NVI/NVA (neovascularization of the iris/neovascularization of the angle) leading to quicker pain relief and quicker lowering of IOP (intraocular pressure).
Proliferative ischemic retinopathies lead to a formation of abnormal vessels on the iris surface induced by an increased level of vascular endothelial growth factor (VEGF). In progressive stages fibrovascular membranes occlude the anterior chamber angle which inhibits aqueous outflow resulting in neovascular glaucoma. The increased intraocular pressure is often difficult to control and frequently results in loss of vision. The aim of this study is to analyze the short- and long-term outcome after adjuvant intraocular Ranibizumab application in patients with neovascular glaucoma and rubeosis and to analyze the role of ranibizumab within a holistic treatment regime.
Assess the efficacy of Avastin as an adjunct to Diode Laser cyclophotocoagulation in the treatment of Neovascular Glaucoma.
To compare the safety and effectiveness between ologen collagen matrix and mitomycin-C (MMC) in glaucoma surgery. The ologen collagen matrix implantation procedure is same as traditional trabeculectomy except implant the ologen collagen matrix on the top of sclera flap after one loose stich the sclera flap. The MMC application is as the standard.
