Figure 1

(A) Immunostaining of neurofilaments (NF-H; DABni). Figures are recomposed in the circle by cut ends of the retina. The magnified retina in the nasal (N; a), inferior (I; b), temporal (T; c) and superior (S; d) quadrants is shown. Axons of the retinal ganglion cells are grouped at their origin and form bundles enveloped by the epineurium. The bundle diameter differs by quadrant: T (c)<S (d)<N (a)<I (b). (B) The difference between phosphorylated (a; SMI-31, DABni) and non-phosphorylated (b; SMI-32) neurofilaments in lamina cribrosa is unremarkable in the temporal quadrant, except for the innermost small bundles near the central vessel. The arteriole of the circle of Haller and Zinn penetrates inside (seen as a circle at the right-central border). The scattered dots in the columns indicate glial cells (a).
