Figure 3. AF of the TM region of a human eye from a 73-year-old donor. Another section TM tissue was flat-mounted with the anterior chamber facing the microscope objective. AF was collected as in Figure 1. Single image snapshots from the 3D reconstruction of the TM region are shown along with corresponding degree of rotation (around the y-axis). 0° represents the aqueous humor face of the TM, while 180° represents the scleral-directed face. A non-fibrous structure present at the aqueous surface (black arrow) can be viewed from the scleral face through an open pore-like structure (white arrow). White scale bar=20 µm.
