Visualization of episcleral vessels (a) and Schlemm's canal (b) with minimal tissue manipulation. Episcleral vessels are seen emanating from deeper, larger-caliber vascular structures. The white bar represents a length of 50 m. Visualization of Schlemm's canal (white arrow) is only possible after a scleral flap is introduced because the microendoscope is limited to a depth of 100 micron in scleral tissue. The white bar in (b) represents a length of 120 m.
