Ocular surface lymphangiography images obtained after subconjunctival injection. A–D, Patients requiring subconjunctival lidocaine injection before intravitreal drug treatment received lidocaine mixed with indocyanine green. A, C, D, Initial bleb is visualized clearly. B, Bleb is below and to the left of the image. A–D, Irregular pathways are seen with intermittent dilations (white arrows) alternating with thin regions along the pathways. E, F, This is in contrast to aqueous angiography, where tracer is placed in the anterior chamber to visualize trabecular and conventional outflow that uses scleral and episcleral veins: (E) left eye of a 61-year-old Asian women and (F) left eye of a 54-year-old Hispanic man. In these patients, the pathways are more organized as a web-like mesh in addition to Y-shaped patterns. They appeared even-calibered throughout. Scale bars = 1 mm.
