Convective Movements Immediately after Iridotomy: Gush Sign

A 56-year-old man presented with iris bombé secondary to pupillary seclusion due to recurrent anterior uveitis (Fig A). Extensive peripheral anterior synechiae (yellow asterisks) were observed with OCT (Solix Full-range OCT; Optovue Inc). Pupillary seclusion (blue asterisks) was also detected. Nd-YAG laser peripheral iridotomy was performed in a superotemporal location (at 10 o’clock). The patency was confirmed by the hole occurrence in iridis (red asterisks; Fig B). High-definition convective movements (i.e., gush sign) in the anterior chamber were detected (white asterisks) 5 minutes after iridotomy when pigmental cells mixed with blood cells, present owing to minimal bleeding, were set in motion (Fig B-C) (Magnified version of Fig A-C is available online at www.aaojournal.org).
