VARIOUS FORMS OF ATROPHY. 357 atrophy assumes very different forms. If the axis is longer, withoutproportionate extension around the papilla, the crescentic form passesinto the semi-elliptical, of which various modifications occur ( a, b, c); if, on the contrary, the atrophy extends more around thenerve-surface, without proportionate prolongation of the axis, the semi-annular form arises (Fig. 133), and further, the annular (Fig. 134),which, when more extended, deserves the name of elliptical (Fig. 136 a)or circular (Fig. 136 b). In all these forms the ring is almost con-stantly broader on the outside than on the inside, where it is often 135 still slenderer than above and beneath. Finally, the atrophy may136a 13Gi> /37
