Figure 4. Series of scanning electron micrographs showing an abnormal posterior suture pattern from a 6 month old RCS rat lens

(A) By dissecting this lens to the axial dimensions of a 2.5 month old lens, a slightly atypical anterior Y suture pattern with a single sub-branch extending to confluence at a dorsal branch (box) is exposed. (B) This dorsal anterior branch and its sub-branch are shown to greater advantage at higher magnification. The cellular surface structure within the boxes shown in (B) are shown to greater advantage at higher magnification in (C) and (D). The ends of fibers are more enlarged than usual as they abut and overlap to form atypical anterior suture branches and sub-branches.
