This triangle consists largely of the fibres of the ciliary mus- 

 cle, which are divided into meridional fibres, or those which 

 occupy the side next the sclera, and radial fibres, which pass

from the point of origin to the hypothenuse ; the circular fibres 

 of Miiller's muscle lie next to the base of the triangle, and are 

 concentrically arranged. 



In highly myopic eyes the meridional and radial fibres

are strongly developed (Fig. 156), while the circular fibres are 

 Scarcely seen, and the angle of the ciliary body at the point of 

 origin is changed from a right to an acute angle.
