Characterization of retinal function and glial cell response in a mouse model of oxygen-induced retinopathy

Abstract

Retinal neovascularization, such as that occurring in proliferative diabetic retinopathy and retinopathy of prematurity, can have serious effects on visual function. By using a mouse model of neovascularization, oxygen-induced retinopathy (OIR), the interplay among angiogenesis, neuronal function, and the macro- and micro-glial response was explored. OIR was induced by exposure of mice to 75% oxygen from postnatal day 7 (P7) to P11 and then room air until P18. Controls were reared in room air. Blood vessel development was assessed by using fluorescence histochemistry. Aberrant intravitreal neovascularization was present across all eccentricities of retina in mice with OIR, whereas the number..
