Figure 5

Images showing bleb-related outflow pathways with valve-like structures. A, D, G, J, Ocular surface lymphangiography images demonstrating irregular pathways with intermittent dilations alternating with thinner areas (white arrows). B, E, H, K, Ocular surface lymphangiography images showing where OCT B-scans were placed along these pathways (green dotted lines). C, F, I, L, Corresponding OCT B-scans demonstrating structures that appeared as semilunar valves, single leaflet valves, or septae (white arrows). M–R, Aqueous angiography with OCT B-scans on trabecular outflow pathways demonstrating episcleral vein luminal pathways (white arrows) that were uniform in diameter and devoid of valves: (M–O) left eye of a 67-year-old Asian man and (P–R) right eye of a 73-year-old White man). Scale bars = 1 mm.
