Figure 1. The drainage angle of a patient with asymptomatic angle closure following a laser iridotomy. An irregular line of dark pigment has been deposited along the Schwalbe line (black arrow) from the iris pigment epithelium. Although pigment was there prior to iridotomy, the density increased afterwards. Posterior to this, lighter-colored pigment tufts have been deposited on the face of the trabecular meshwork from the adjacent iris stroma (white arrow).
