- W4253313883 abstract "As with all surgeries, numerous complications can occur with tube shunts; one particular complication is hypotony. Early hypotony is defined as intraocular pressure (IOP) of less than 6 mm Hg and occurs before maturation of the fibrotic capsule around the tube shunt plate. The physiologic development of the capsule typically occurs during the first postoperative 4–6 weeks after implantation. Late hypotony can be defined as IOP of less than 6 mm Hg that occurs after the plate is encysted. Hypotony in and of itself may not require treatment unless secondary complications develop (see Chapter 10 and 34). Untreated, hypotony can result in shallowing or flattening of the anterior chamber, corneal decompensation (see Chapter 40), peripheral anterior synechiae, cataract, maculopathy (see Chapter 22), optic nerve edema, choroidal effusion or hemorrhage (see Chapter 6), and even endophthalmitis (see Chapter 42). Although hypotony is common in the early postoperative period, it is less common as a late complication. Knowing how to prevent and manage late hypotony is essential for long-lasting surgical success. Persistent hypotony is less common with tube shunts than with trabeculectomy. In the Tube Versus Trabeculectomy Study, of the 107 eyes in the tube group, none had persistent hypotony, whereas of the 105 eyes in the trabeculectomy group, 3 developed persistent hypotony. A pediatric population study comparing trabeculectomy with mitomycin-C (24 eyes) with Ahmed™ (New World Medical, Inc., Rancho Cucamonga, California) or Baerveldt® (Abbott Medical Optics, Inc., Santa Ana, California) shunts (46 shunts total) had one eye in the trabeculectomy group with late hypotony, while no eyes in shunt group developed persistent hypotony. WuDunn et al implanted 250 mm Baerveldt® devices in 108 patients, with 5 failing due to persistent hypotony. In all likelihood, late hypotony in the WuDunn et al study was due to either progression of underlying disease resulting in less aqueous production or secondary to another complication of shunt surgery. However, across the different types of shunts, the incidences of early and late hypotony are not significantly different." @default.
