Toxic anterior segment syndrome (TASS) is an acute postoperative inflammatory reaction in which a noninfectious substance enters the anterior segment and induces toxic damage to the intraocular tissues. Toxic anterior segment syndrome (TASS) is an acute postoperative sterile inflammatory reaction that occurs 12–48 h following uneventful cataract surgery. Sterile endophthalmitis appears as an infrequent complication of intravitreal injections and seems to develop mainly in the context of the off-label use of drugs that have not been conceived for intravitreous administration. In the past this condition was known by many names, such as postoperative uveitis and sterile endophthalmitis. Absence of vitreous inflammation is the most significant difference between TASS and endophthalmitis. Toxic Anterior Syndrome (TASS) is a rare sequela of uncomplicated anterior segment surgery. Although there are well known risk factors for postoperative endophthalmitis, some prophylaxis strategies remain controversial.
