Figure 6.

Flat-mounted monkey macula. (A) GS labeling of a flat-mounted macula showing the very dense concentric disposition of glial Müller cells around the fovea centralis. Inset shows a higher magnification of the fovea where glial cells are still present but out of focus. Nuclei are stained in blue. (B, C) Histological section of a monkey macula and computerized reconstitution of GS/PNA-labeled flat-mounted monkey fovea. Outer segments of central cones (green) are longer and in contact with glial Müler cells apical processes (red).

Abbreviation: GS, glutamine synthetase.
