Filter by:This clinical trial, involving participants with rhegmatogenous retinal detachment, aims to compare Methotrexate Usage Techniques in preventing Proliferative Vitreoretinopathy (PVR) after vitrectomy. The study will evaluate the development of PVR, retinal detachment recurrence, and improvement in visual acuity. Participants will undergo retinal detachment surgery using the vitrectomy technique and will be divided into two groups. One group will receive Methotrexate infusion during surgery, while the other will receive repeated Methotrexate injections post-surgery. The researcher will analyze and compare outcomes between the two groups.
The purpose of this study is to determine if a drug called netarsudil is safe and able to prevent the development of scar tissue after retinal detachment repair. Patients eligible for this study are those diagnosed with a rhegmatogenous retinal detachment deemed at high risk for scar tissue formation (a process called 'proliferative vitreoretinopathy').
Management of primary retinal detachment due to upper retinal break is one of controversial situation that may face ophthalmologists in vitreoretinal subspecialty.
The primary objective of the study is to determine if serial intravitreal aflibercept injections (IAI) improve the single surgery anatomic success rate following surgical repair of primary, macula involving rhegmatogenous retinal detachment (RRD) deemed at high risk for proliferative vitreoretinopathy (PVR). Preclinical work has revealed that competitive inhibition of platelet derived growth factor (PDGF) by vascular endothelial growth factor (VEGF) potentiates a pathologic, sustained activation of PDGF receptors that is critical to the progression of experimental PVR. VEGF blockade would mitigate this pathologic activation.
This multicenter randomized clinical trial evaluates the effect of multiple intra-silicone oil injections of methotrexate (MTX) on rhegmatogenous retinal detachment (RRD) with grade C proliferative vitreoretinopathy (PVR). 74 eyes with the diagnosis of RRD with PVR grade C will be randomized into two groups: the intervention group and the control group. All eyes undergo pars plana vitrectomy(PPV) and intraocular injection of silicone oil (SO). At the end of the surgical procedure, intra-SO injection of 250 µg MTX will be performed in the intervention group. No intra-SO injection will be done in the control group. In the intervention group, Intra-SO injection of MTX will be repeated at 3 and 6 weeks postoperatively. Silicone oil removal will be done 3 months after surgery.Spectral-domain optical coherence tomography (SD-OCT) image of the macula will be acquired at months 3 and 6. The retinal reattachment rate at months 6 will be assessed as the main outcome measure of the study. Best corrected visual acuity, retinal reproliferation rate and adverse events are the secondary outcome measures. Comprehensive ocular examination will be performed at weeks 1, 3, 6 and at months 3, 4 and 6.
To evaluate the efficacy of oral colchicine combined with intraoperative infusion of dexamethasone, low molecular weight heparin and 5-FU during vitrectomy for management of established proliferative vitreoretinopathy (PVR)
