VEGFA and age-related macular degeneration: A clinical trial (NCT04439708) is now ongoing to disclose biomarkers in the blood and aqueous humor in a population of AMD with occult CNV and analyse their relationship with the response to anti-VEGF treatment; another one (NCT05038371) aims to measure levels of connective tissue growth factor (CTGF) in the aqueous humor of patients with neovascular AMD and compare them to controls.
