Anti-VEGF therapy in the management of retinopathy of prematurity: what we learn from representative animal models of oxygen-induced retinopathy.
Retinopathy of prematurity (ROP) remains a leading cause of childhood blindness, affecting infants born prematurely. ROP is characterized by the onset of delayed physiological retinal vascular development (PRVD) and followed by pathologic neovascularization into the vitreous instead of the retina, called intravitreal neovascularization (IVNV). Therefore, the therapeutic strategy for treating ROP is to promote PRVD and inhibit or prevent IVNV. Vascular endothelial growth factor (VEGF) plays an important role in the pathogenesis of ROP. There is a growing body of studies testing the use of anti-VEGF agents as a treatment for ROP. Intravitreal anti-VEGF treatment for ROP has potential advantages compared with laser photocoagulation, the gold standard for the treatment of severe ROP; however, intravitreal anti-VEGF treatment has been associated with reactivation of ROP and suppression of systemic VEGF that may affect body growth and organ development in preterm infants. Therefore, it is important to understand the role of VEGF in PRVD and IVNV. This review includes the current knowledge of anti-VEGF treatment for ROP from animal models of oxygen-induced retinopathy (OIR), highlighting the importance of VEGF inhibition by targeting retinal Müller cells, which inhibits IVNV and permits PRVD. The signaling events involved in mediating VEGF expression and promoting VEGF-mediated angiogenesis, including hypoxia-dependent signaling, erythropoietin/erythropoietin receptor-, oxidative stress-, beta-adrenergic receptor-, integrin-, Notch/Delta-like ligand 4- and exon guidance molecules-mediated signaling pathways, are also discussed.
期刊介绍:
Eye and Brain is an international, peer-reviewed, open access journal focusing on basic research, clinical findings, and expert reviews in the field of visual science and neuro-ophthalmology. The journal’s unique focus is the link between two well-known visual centres, the eye and the brain, with an emphasis on the importance of such connections. All aspects of clinical and especially basic research on the visual system are addressed within the journal as well as significant future directions in vision research and therapeutic measures. This unique journal focuses on neurological aspects of vision – both physiological and pathological. The scope of the journal spans from the cornea to the associational visual cortex and all the visual centers in between. Topics range from basic biological mechanisms to therapeutic treatment, from simple organisms to humans, and utilizing techniques from molecular biology to behavior. The journal especially welcomes primary research articles or review papers that make the connection between the eye and the brain. Specific areas covered in the journal include: Physiology and pathophysiology of visual centers, Eye movement disorders and strabismus, Cellular, biochemical, and molecular features of the visual system, Structural and functional organization of the eye and of the visual cortex, Metabolic demands of the visual system, Diseases and disorders with neuro-ophthalmic manifestations, Clinical and experimental neuro-ophthalmology and visual system pathologies, Epidemiological studies.
