Intravitreal triamcinolone inhibits choroidal neovascularization. To investigate if vascular endothelial growth factor (VEGF) is affected, we examined VEGF expression after intravitreal triamcinolone administration in rat retina. Using in situ hybridization, we have found dense clustered VEGF mRNA signals in the retinal pigment epithelium, moderate patchy signals in the inner nuclear layer, and...
PURPOSE To investigate the clearance of vascular endothelial growth factor (VEGF) after the induction of posterior vitreous detachment by plasmin and/or SF(6). METHODS The study design included four groups of rabbits: group 1 received an intravitreal injection of plasmin and SF(6) in the right eye, group 2 received an intravitreal injection of plasmin in the right eye, group 3 received an int...
We examined the effect of nutritional supplements (modified Age Related Eye Disease Study (AREDS)-II formulation containing vitamins, minerals, lutein, resveratrol, and omega-3 fatty acids) on choroidal neovascularization (CNV). Supplements were administered alone and combined with intravitreal anti-VEGF in an early-CNV (diode laser-induced) murine model. Sixty mice were evenly divided into gro...
Age-related macular degeneration (AMD) is a potentially blinding posterior segment disease; inflammatory responses and subretinal drusen formation lead to leaky blood vessels. The current treatment method involves intravitreal injections of anti-VEGF agents, which highly invasive requires frequent administered by trained personnel. Periocular such as trans-/intra-scleral would provide minimally...
Purpose The formation of macular hole after receiving anti-vascular endothelial growth factor (anti-VEGF) therapy is rare. We report a case of macular hole that occurred after intravitreal injection of an anti-VEGF agent for age-related macular degeneration (AMD) in a patient, who underwent vitrectomy combined with choroidal neovascularization (CNV) removal. Observations A 64-year-old female ...
roidal neovascularization with similar efficacy as anti-VEGF antibodies (Rennel et al. 2011). Several studies have shown that the simultaneous blockade of Ang-2/Tie2 and VEGF pathways reduces vascular leakage and tumour sprouting angiogenesis and has an additive effect to single-agent treatment without apparent increased systemic toxicity (Koh et al. 2010). Combined inhibition of Tie-2 and VEGF...
conclusions vpa and cbz treatments caused a decrease in β-catenin and vegf levels in sw480 colon cancer cell lines. these results suggest that cbz can be considered a potential antitumor drug with potencies different from vpa. methods in the present experimental study, implemented during 2014 - 2015 in iran, after incubation of cells into 96-well plates with 5,500 cells/well, the tested drugs w...
PURPOSE To report a case with ischemic macular edema (ME) due to an acute branch retinal vein occlusion (BRVO) which was treated with repeated intravitreal anti-VEGF injections. METHODS Retrospective case presentation. RESULTS A 66-year-old female patient was treated with repeated intravitreal anti-VEGF injections due to ischemic ME following an acute BRVO. Over a period of 2.5 years best c...
PURPOSE To examine vitreous succinate levels from proliferative diabetic retinopathy (PDR) patients and ascertain their association with PDR activity. DESIGN Comparative case series. METHODS A total of 81 eyes of 72 PDR patients were divided into active PDR (22 eyes), quiescent PDR (21 eyes), and active PDR with intravitreal bevacizumab injection (38 eyes). Twenty epiretinal membrane (ERM) ...
We treated 26 eyes of 25 young patients having a mean age of 30 years with intravitreal vascular endothelial growth factor (VEGF) inhibitor for choroidal new vessel (CNV) formation overlying choroidal osteoma over a mean follow-up of 26 months. Mean number of injections was 2.4 at 6 months, 3.2 at 12 months, and 5.5 at 24 months. CNV was subfoveal in 14 eyes, juxtafoveal in 5, extrafoveal in 5,...
