Figure 4. Serial sections of the TM region imaged by 2 photon microscopy. Sections shown here are indicated by the distance from the edge of the tissue block (in microns). The Schlemm’s Canal (SC) opening is apparent in many of the sections. Also prevalent is a ~50 µm round structure, representing a collector channel (CC), visible from the 900 µm section through the 2400 µm section. Black bar=100 µm.
