Vascular endothelial growth factor (VEGF) has been shown to be an endothelial cell-specific mitogen and an angiogenic inducer in a variety of in vitro and in vivo models. Furthermore, it has been demonstrated to increase retinal vessel permeability by increasing the phosphorylation of tight junction proteins. Recent work has found elevated levels of VEGF in ocular fluids of patients with proliferative diabetic retinopathy (PDR). Thus, it makes sense to consider anti-VEGF treatments in the management of PDR. The purpose of the current research is to determine if intravitreal bevacizumab as anti-VEGF is helpful in the management of complications of PDR.
血管内皮生长因子(VEGF)在多种体外和体内模型中已被证明是一种内皮细胞特异性促有丝分裂原和血管生成诱导剂。此外,它已被证实可通过增加紧密连接蛋白的磷酸化来提高视网膜血管通透性。最近的研究发现,增殖性糖尿病视网膜病变(PDR)患者眼内液中VEGF水平升高。因此,在PDR的治疗中考虑抗VEGF治疗是合理的。本研究的目的是确定玻璃体内注射贝伐单抗作为抗VEGF药物是否有助于治疗PDR的并发症。
