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
Signs that may indicate a pathological process include: (i) focal changes in the neuroretinal rim eg, notching or focal thinning (Figure 1) (ii) acquired pits of the optic nerve (iii) blood vessel signs such as baring and nasalisation of vessels (Figure 2), and (iv) peri-papillary atrophy (Figure 3); if these signs are associated with corresponding visual field defects, the likelihood of glaucoma increases.
