Intravitreal injection of the heparin analog 5-amino-2-naphthalenesulfonate reduces retinal neovascularization in mice.

The effect of the heparin analog 5-amino-2-naphthalenesulfonate (5-amino-2-NMS) on retinal neovascularization was investigated in the mouse model for oxygen-induced retinopathy (OIR). From postnatal day 7 (P7) until P12, mice were kept in a 75% oxygen environment. On P12, they received an intravitreal injection of 10mM 5-amino-2-NMS in one eye and PBS as control substance in the fellow eye.
