To investigate the association between the vascular endothelial growth factor (VEGF) gene and response to either intravitreal bevacizumab (IVB) or photodynamic therapy with intravitreal triamcinolone acetonide and IVB (triple therapy) for neovascular age-related macular degeneration (AMD).
Vascular endothelial growth factor (VEGF) plays an important role in the pathogenesis of neovascular age-related macular degeneration and diabetic retinopathy.
Alternative splicing of the last exon (exon 8) of vascular endothelial growth factor (VEGF) pre-mRNA is a key element in the balance of pro- and anti-angiogenic VEGF isoforms in exudative age-related macular degeneration (exAMD) and proliferative diabetic retinopathy (PDR).
Suggestive association between PLA2G12A single nucleotide polymorphism rs2285714 and response to anti-vascular endothelial growth factor therapy in patients with exudative age-related macular degeneration.
To determine whether there is an association between CFH, ARMS2, HTRA1, VEGF, SERPING1 or C3 genotypes and patient response to treatment with intravitreal bevacizumab for neovascular age-related macular degeneration (AMD).
Three previously reported associations of response to VEGF inhibition in nAMD involving single nucleotide polymorphisms (SNPs) at the CFH, FZD4, and HTRA1/ARMS2 loci were tested for replication.
Ocular anti-VEGF therapy is highly effective for treating a subset of patients with blinding eye disorders such as diabetic retinopathy and neovascular age-related macular degeneration (AMD).
Three Variants of or near VEGF-A Gene are Not Associated with Neovascular Age-Related Macular Degeneration and Polypoidal Choroidal Vasculopathy in a Han Chinese Population.
Our findings support the dominant role of VEGF-A121 in neovascular age-related macular degeneration but hint that VEGF-A165 may have an equivalent role in other neovascular retinal pathology.
The aberrant vessels in the Vldlr(-/-) retinas, which invade normally avascular photoreceptors, are reminiscent of the vascular defects in retinal angiomatous proliferation, a subset of neovascular age-related macular degeneration (AMD), which is associated with high vitreous VEGFA levels in humans.
This study suggests that genetic variation in NRP1, a key molecule in VEGFA-driven neovascularization, influences treatment response to ranibizumab in nvAMD patients.
