Images showing bleb-related outflow pathway structural evaluation. A, Ocular surface lymphangiography image showing irregular pathways off a bleb. B, Anterior segment (AS) OCT of this region (green dotted line in (A)) demonstrating lumens that match between the angiographic image and OCT image (white arrows). C, Complex bleb-related outflow pathways can be elicited by ocular surface lymphangiography. D, Careful observation allowed delineation of interwoven pathways (red and blue). E, F, These pathways could be identified as lumens on AS OCT (the OCT in (E) represents the top B-scan green dotted line in (D), and the OCT in (F) represents the bottom B-scan green dotted line in (D)). Scale bars = 500 μm.
