Toxic anterior segment syndrome (TASS) is a rare but serious complication of intraocular surgery that occurs when a non-infectious toxic agent enters the anterior segment of the eye and causes an inflammatory reaction. Since June 2004, ambulatory surgical facilities have submitted at least 15 reports of TASS to PA-PSRS, and at least three facilities have reported multiple cases. TASS incidence is difficult to pin-point for several reasons, including that TASS is often confused with and treated as infectious endophthalmitis. (More information on TASS is included in the December 2006 PA-PSRS Patient Safety Advisory.
