CD160 represents a new angiogenic factor as its specific engagement by an agonist monoclonal antibody directed against human CD160 reduced angiogenesis of endothelial cells with a distinct mechanism from current angiogenic therapies that target the VEGF/VEGF-R pathway. A soluble form of CD160, sCD160, has been found to be highly expressed in the vitreous and the sera of patients with severe diabetic retinopathies, and can now be dosed with help of an ELISA test. The investigators aim to evaluate the association between ischaemic retinopathies (patients with or without) and sCD160 concentrations in the vitreous, the aqueous humour and the serum.
