title: Iris synechia after laser goniopuncture in a patient having deep sclerectomy with a collagen implant.
abstract: Neodymium:YAG (Nd:YAG) goniopuncture is an efficient and safe treatment for low filtration through the trabeculo-Descemet's membrane after deep sclerectomy with a collagen implant (DSCI). The only reported complication of this procedure is choroidal detachment. However, we found an iris synechia in a patient whose intraocular pressure (IOP) was elevated again 1 month after Nd:YAG goniopuncture. Synechiolysis and peripheral iridectomy with Nd:YAG and argon lasers effectively removed the iris synechia, and IOP immediately dropped to the normal range. We believe that iris synechia is a potential complication that may cause elevated IOP after laser goniopuncture in patients having DSCI.
