bayonetting sign (characterised by double angulation of a blood vessel over the edge of the disc): with neuroretinal rim loss between the outer edge of the cup and the optic disc margin, a vessel entering the disc from the retina may angle sharply backwards into the disc and then turn towards the original direction
