Fig. 19. Anterior and lenticular girdle zonular fibers. A. Circumferential zonular fibers (arrows) lying over the crests of the ciliary processes are attached to the anterior hyaloid membrane, which has not been removed in this intact eye. Lens and posterior zonular fibers are visible above (Gomori's hematoxylin, × 15). B. Anterior hyaloid membrane removed as a sheet from the same specimen. Many circumferential zonular fibers (horizontal) and posterior zonules (vertical) remain adherent to the membrane. The horizontal fibers include scanty lenticular (above) and more plentiful anterior ciliary girdle fibers below (Gomori's hematoxylin, × 60). C. Anterior hyaloid membrane with attaching posterior zonules on peripheral lens capsule and associated horizontal lenticular girdle fibers (flat preparation, immunostained for fibrillin-1, × 60). |
